In typewriting, the stimulus is the copy, or the idea of what is to be written, and the response is the striking of the keys in the proper order. Speaking generally, we may say that the stimulus is the force or forces which excite the sense organs, and thereby, through the nervous system, bring about a muscular response.

This is the ordinary type of action, but we have already indicated a different type. In speaking of typewriting we said the stimulus might be either the copy or ideas. One can write from copy or dictation, in which the stimulus is the written or spoken word, but one can also write as one thinks of what one wishes to write. The latter is known as centrally initiated action. That is to say, the stimulus comes from within, in the brain, rather than from without.

Let us explain this kind of stimulation a little further. Suppose I am sitting in my chair reading. I finish a chapter and look at my watch. I notice that it is three o'clock, and recall that I was to meet a friend at that time. The stimulus in this case is in the brain itself; it is the nervous activity which corresponds to the idea of meeting my friend. If we disregard the distinction between mind and body, we may say that the stimulus for a response may be an idea as well as a perception, the perception arising from the immediate stimulation of a sense organ, and the idea arising from an excitation of the brain not caused by an immediate stimulation of a sense organ.

Instincts and Habits. In human action it is evident that there is always a stimulus to start the nerve-impulse which causes the action. If we make inquiry concerning the connection between the stimulus and response; if we ask how it has come about that a particular stimulus causes a particular response rather than some other possible response, we find two kinds of causes. In one case the causal connection is established through heredity; in the other, the causal connection is established during a person's lifetime through training.

A chicken, for example, hides under some cover the first time it hears the cry of a hawk; it scratches the first time its feet touch sand or gravel; it pecks the first time it sees an insect near by. An infant closes its eyes the first time it feels cold wind blow upon them; it cries the first time it feels pain; it clasps its fingers together the first time a touch is felt inside them. The child's nervous system is so organized that, in each of the cases named, the stimulus brings forth the particular, definite response. These acts do not have to be learned.

But it is quite different in typewriting and piano playing. One must learn what keys on the piano to strike in response to the various situations of the notes as written in the music. One must also learn the keys on the typewriter before he can operate a typewriter. And in the case of other habits, we find, for example, that one does not respond by saying "81" for 9 times 9; nor "13" for 6 plus 7; nor "8" for 15 minus 7; nor "8" for the square root of 64; nor "144" for the square of 12, etc., until one has learned in each case.

Some connections between stimulus and response we have through inheritance; all others are built up and established in one's lifetime, particularly in the first thirty years of one's life.

We have spoken of bonds between stimulus and response, but have not explained just what can be meant by a bond. In what sense are stimulus and response bound together? A bond is a matter of greater permeability, of less resistance in one direction through the nervous system than in other directions. Nerves are conductors for nerve-currents. When a nerve-current is started in a sense organ, it passes on through the path of least resistance.

Now, some nerves are so organized and connected through inheritance as to offer small resistance. This forms a ready-made connection between stimulus and response. Muscular responses that are connected with their stimuli through inherited bonds, by inherited nerve structure, are called instincts. Those that are connected by acquired bonds are called habits. Sucking, crying, laughing, are instinctive acts. Adding, typewriting, piano playing, are habits.

The term instinct may be given to the act depending upon inherited structure, an inherited bond, or it may be given to the inherited bond itself. Similarly, the term habit may be given to an act that we have had to learn or to the bond which we ourselves establish between response and stimulus. In this book we shall usually mean by instinct an action depending upon inherited structure and by habit an act depending upon a bond established during lifetime. A good part of our early lives is spent in building up bonds between stimuli and responses. This establishing of bonds or connections is called learning.

Appearance of Inherited Tendencies. Not all of our inherited tendencies are manifested immediately after birth, nor indeed in the earliest years of childhood, but appear at different stages of the child's growth. It has already been said that a child, soon after birth, will close its eyelids when they are blown upon. The lids do not close at this time if one strikes at them, but they will do this later. The proper working of an instinct or an inherited tendency, then, depends upon the child's having reached a certain state of development.

The maturing of an instinct depends upon both age and use, that is to say, upon the age of the animal and the amount of use or exercise that the instinctive activity has had. The most important factor, however, seems to be age. While our knowledge of the dependence of an instinct upon the age of the animal is not quite so definite in the case of human instincts, the matter has been worked out in the case of chickens.

The experiment was as follows: Chickens were taken at the time of hatching, and some allowed to peck from the first, while others were kept in a dark room and not allowed to peck. When the chickens were taken out of the dark room at the end of one, two, three, and four days, it was found that in a few hours they were pecking as well as those that had been pecking from birth. It seems probable, if we may judge from our limited knowledge, that in the human child, activities are for the most part dependent upon the age of the child, and upon the state of development of the nervous system and of the organs of the body.

Significance of Inherited Tendencies. Although human nature is very complex, although human action nearly always has some element of habit in it, nevertheless, inborn tendencies are throughout life powerful factors in determining action. This will at once be apparent if we consider how greatly we are influenced by anger, jealousy, love, fear, and competition. Now we do not have to learn to be jealous, to hate, to love, to be envious, to fight, or to fear. These are emotions common to all members of the human race, and their expression is an inborn tendency. Throughout life no other influences are so powerful in determining our action as are these. So, although most of our detailed actions in life are habits which we learn or acquire, the fundamental influences which decide the course of our action are inherited tendencies.

Classification of Instincts. For convenience in treatment the instincts are grouped in classes. Those instincts most closely related to individual survival are called individualistic instincts. Those more closely related to the survival of the group are called socialistic. Those individualistic tendencies growing out of periodic changes of the environment may be called environmental instincts. Those closely related to human infancy, adapting and adjusting the child to the world in which he lives, may be called adaptive. There is still another group of inherited tendencies connected with sex and reproduction, which are not discussed in this book.

We shall give a brief discussion of the instincts falling under these various classes. It must be remembered, however, that the psychology of the instincts is indefinite and obscure. It is difficult to bring the instincts into the laboratory for accurate study. For our knowledge of the instincts we are dependent, for the most part, on general observation. We have had a few careful studies of the very earliest years of childhood. However, although from the theoretical point of view our knowledge of the instincts is incomplete, it is sufficient to be of considerable practical value.

The Individualistic Instincts. Man's civilized life has covered but a short period of time, only a few hundred or a few thousand years. His pre-civilized life doubtless covered a period of millions of years. The inborn tendencies in us are such as were developed in the long period of savage life. During all of man's life in the time before civilization, he was always in danger. He had many enemies, and most of these enemies had the advantage of him in strength and natural means of defense. Unaided by weapons, he could hardly hold his own against any of the beasts of prey. So there were developed in man by the process of natural selection many inherited responses which we group under the head of fear responses.

Just what the various situations are that bring forth these responses has never been carefully worked out. But any situation that suddenly puts an individual in danger of losing his life brings about characteristic reactions. The most characteristic of the responses are shown in connection with circulation and respiration. Both of these processes are much interfered with. Sometimes the action is accelerated, at other times it is retarded, and in some cases the respiratory and circulatory organs are almost paralyzed. Also the small muscles of the skin are made to contract, producing the sensation of the hair standing on end. Just what the original use of all these responses was it is difficult now to work out, but doubtless each served some useful purpose.

Whether any particular situations now call forth inherited fear responses in us is not definitely established. But among lower animals there are certain definite and particular situations which do call forth fear responses. On the whole, the evidence rather favors the idea of definite fear situations among children. It seems that certain situations do invariably arouse fear responses. To be alone in the dark, to be in a strange place, to hear loud and sudden noises, to see large, strange animals coming in threatening manner, seem universally to call forth fear responses in children.

However, the whole situation must always be considered. A situation in which the father or mother is present is quite different from one in which they are both absent. But it is certain that these and other fears are closely related to the age and development of the child. In the earlier years of infancy, certain fears are not present that are present later. And it can be demonstrated that the fears that do arise as infancy passes on are natural and inherited and not the result of experience.

Few of the original causes of fear now exist. The original danger was from wild animals chiefly. Seldom are we now in such danger. But of course this has been the case for only a short time. Our bodies are the same sort of bodies that our ancestors had, therefore we are full of needless fears. During the early years of a child's life, wise treatment causes most of the fear tendencies to disappear because of disuse. On the other hand, unwise treatment may accentuate and perpetuate them, causing much misery and unhappiness. Neither the home nor the school should play upon these ancestral fears. We should not try to get a child to be good by frightening him; nor should we often use fear of pain as an incentive to get a child to do his work.

Man has always been afraid, but he has also always been a fighter. He has always had to fight for his life against the lower animals, and he has also fought his fellow man. The fighting response is connected with the emotions of anger, envy, and jealousy. A man is angered by anything that interferes with his life, with his purposes, with whatever he calls his own. We become angry if some one strikes our bodies, or attacks our beliefs, or the beliefs of our dear friends, particularly of our families. The typical responses connected with anger are such as faster heart-beat, irregular breathing, congestion of the blood in the face and head, tightening of the voluntary muscles, particularly a setting of the teeth and a clinching of the fists. These responses are preparatory to actual combat.

Anger, envy, and jealousy, and the responses growing out of them, have always played a large part in the life of man. A great part of history is a record of the fights of nations, tribes, and individuals. If the records of wars and strifes, and the acts growing out of envy and jealousy and other similar emotions should be taken out of history, there would not be much left. Much of literature and art depict those actions of man which grew out of these individualistic aspects of his nature. Competition, which is an aspect of fighting, even to the present day, continues to be one of the main factors in business and in life generally. Briefly, fighting responses growing out of man's selfishness are as old as man himself, and the inherited tendencies connected with them are among the strongest of our natures.

In the training of children, one of the most difficult tasks is to help them to get control over the fighting instinct and other selfish tendencies. These tendencies are so deeply rooted in our natures that it is hard to get control of them. In fact, the control which we do get over them is always relative. The best we can hope to do is to get control over our fighting tendencies in ordinary circumstances.

It is doubtful whether it would be good for us if the fighting spirit should disappear from the race. It puts vim and determination into the life of man. But our fighting should not be directed against our fellow man. The fighting spirit can be retained and directed against evil and other obstacles. We can learn to attack our tasks in a fighting spirit. But surely the time has come when we should cease fighting against our neighbors.

Social Tendencies. Over against our fighting tendencies we may set the socialistic tendencies. Cooeperative and sympathetic actions grow out of original nature, just as truly as do the selfish acts. But the socialistic tendencies are not, in general, as strong as are the individualistic ones. What society needs is the strengthening of the socialistic tendencies by use, and a weakening of at least some of the individualistic tendencies, by control and disuse.

Socialistic tendencies show themselves in gangs and clubs formed by children and adults. It is, therefore, a common practice now to speak of the "gang" instinct. Human beings are pleased and content when with other human beings and not content, not satisfied, when alone. Of course circumstances make a difference in the desires of men, but the general original tendency is as stated.

The gang of the modern city has the following explanation: Boys like to be with other boys. Moreover, they like to be active; they want to be doing something. The city does not provide proper means for the desired activities, such as hunting, fishing, tramping, and boating. It does not provide experiences with animals, such as boys have on the farm. Much of the boy's day is spent in school in a kind of work not at all like what he would do by choice. There is not much home life. Usually there is not the proper parental control. Seldom do the parents interest themselves in planning for the activities of their children. The result is that the boys come together on the streets and form a club or gang. Through this organization the boy's nature expresses itself. Without proper guidance from older people, this expression takes a direction not good for the future character and usefulness of the boy.

The social life of children should be provided for by the school in cooeperation with the home. The school or the schoolroom should constitute a social unit. The teacher with the parents should plan the social life of the children. The actual work of the school can be very much socialized. There can be much more cooeperation and much more group work can be done in the school than is the case at present. And many other social activities can be organized in connection with the school and its work. Excursions, pageants, shows, picnics, and all sorts of activities should be undertaken.

The schoolhouse should be used by the community as the place for many of its social acts and performances. Almost every night, and throughout the summer as well as in the winter, the people, young and old, should meet at the school for some sort of social work or play. The Boy Scouts should be brought under the control of the school to help fulfill some of its main purposes.

Environmental Instincts. In this class there are at least two tendencies which seem to be part of the original nature of man; namely, the wandering and the collecting tendencies.

Wandering. The long life that our ancestors lived free and unrestrained in the woods has left its effect within us. One of the greatest achievements of civilization has been to overcome the inherited tendencies to roam and wander, to the extent that for the most part we live out our lives in one home, in one family, doing often but one kind of work all our lives. Originally, man had much more freedom to come and go and do whatever he wished.

Truancies and runaways are the result of original tendencies and desires expressing themselves in spite of training, perhaps sometimes because of the lack of training. In childhood and youth these original tendencies should, to some extent, be satisfied in legitimate ways. Excursions and picnics can be planned both for work and for play. If the child's desires and needs can be satisfied in legitimate ways, then he will not have to satisfy them illegitimately. The teaching itself can be done better by following, to some extent, the lead of the child's nature. Much early education consists in learning the world. Now, most of the world is out of doors and the child must go out to find it. The teacher should make use of the natural desires of the children to wander and explore, as a means of educating them. The school work should be of such a nature that much outdoor work will need to be done.

Collecting. It is in the nature of children to seize and, if possible, carry away whatever attracts attention. This tendency is the basis of what is called the collecting instinct. If one will take a walk with a child, one can observe the operation of the collecting tendency, particularly if the walk is in the fields and woods. The child will be observed to take leaves, flowers, fruits, seeds, nuts, pebbles, and in fact everything that is loose or can be gotten loose. They are taken at first aimlessly, merely because they attract attention. The original, natural response of the child toward that which attracts attention is usually to get it, get possession of it and take it along. It is easy to see why such tendencies were developed in man. In his savage state it was highly useful for him to do this. He must always have been on the lookout for things which could be used as food or as weapons. He had to do this to live. But one need not take a child to the woods to observe this tendency. One can go to the stores. Till a child is trained not to do it, he seizes and takes whatever attracts attention.

Just as the wandering tendencies can be used for the benefit of the child, so can the collecting tendencies. Not only should the children make expeditions to learn of the world, but specimens should be collected so that they can be used to form a museum at the school which will represent the surrounding locality. Geological, geographical, botanical, and zooelogical specimens should be collected. The children will learn much while making the collections, and much from the collections after they are made.

"Education could profit greatly by making large demands upon the collecting instinct. It seems clear that in their childhood is the time when children should be sent forth to the fields and woods, to study what they find there and to gather specimens. The children can form naturalists' clubs for the purpose of studying the natural environment. Such study should embrace rocks, soils, plants, leaves, flowers, fruits, and specimens of the wood of the various trees. Birds and insects can be studied and collected. The work of such a club would have a twofold value. (1) The study and collecting acquaint the child with his natural environment, and in doing it, afford a sphere for the activity of many aspects of his nature. They take him out of doors and give an opportunity for exploring every nook and corner of the natural environment. The collecting can often be done in such a way as to appeal to the group instincts. For example, the club could hold meetings for exhibiting and studying the specimens, and sometimes the actual collecting could be done in groups. (2) The specimens collected should be put into the school museum, and the aim of this museum should be to represent completely the local environment, the natural and physical environment, and also the industrial, civil, and social environment. The museum should be completely illustrative of the child's natural, physical, and social surroundings. The museum would therefore be educative in its making, and when it is made, it would have immense value to the community, not only to the children but to all the people. In this museum, of course, should be found the minerals, rocks, soils, insects,—particularly those of economic importance,—birds, and also specimens of the wild animals of the locality. If proper appeal is made to the natural desire of the children, this instinct would soon be made of service in producing a very valuable collection. The school museum in which these specimens are placed should also include other classes of specimens. There should be specimens showing industrial evolution, the stages of manufacture of raw material, specimens of local historical interest, pictures, documents, books. The museum should be made of such a nature that parents would go there nearly as often as the children. The school should be for the instruction of all the people of the community. It should be the experiment station, the library, the debating club, the art gallery for the whole community."[2]

Imitation. One of the fundamental original traits of human nature is the tendency to imitate. Imitation is not instinctive in the strict meaning of the word. Seeing a certain act performed does not, apart from training and experience, serve as a stimulus to make a child perform a similar act. Hearing a certain sound does not serve as a stimulus for the production of the same sound. Nevertheless, there is in the human child a tendency or desire to do what it sees others doing.

A few hours spent in observing children ought to convince any one of the universality and of the strength of this tendency. As our experience becomes organized, the idea of an act usually serves as the stimulus to call it forth. However, this is not because the idea of an act, of necessity, always produces the act. It is merely a matter of the stimulus and the response becoming connected in that way as the result of experience. Our meaning is that an act can be touched off or prompted by any stimulus. Our nervous organization makes this possible. The particular stimulus that calls forth a particular response depends upon how we have been trained, how we have learned. In most cases our acts are coupled up with the ideas of the acts. We learn them that way.

In early life particularly, the connection between stimulus and response is very close. When a child gets the idea of an act, he immediately performs the act, if he knows how. Now, seeing another perform an act brings the act clearly into the child's consciousness, and he proceeds to perform it. But the act must be one which the child already knows how to perform, otherwise his performance of it will be faulty and incomplete. If he has never performed the particular act, seeing another perform the act sets him to trying to do it and he may soon learn it. If he successfully performs an act when he sees it done by another, the act must be one which he already knows how to perform, and for whose performance the idea has already served as a stimulus. Now if imitation were instinctive in the strict sense, one could perform the act for the first time merely from seeing another do it, without any previous experience or learning. It is doubtful whether there are any such inherited connections. It is, however, true that human beings are of such a nature that, particularly in early life, they like to do and want to do what they see others doing. This is one of the most important aspects of human nature, as we shall see.

Function and Importance of Imitation in Life. Natural selection has developed few aspects of human nature so important for survival as the tendency to imitate, for this tendency quickly leads to a successful adjustment of the child to the world in which he lives. Adult men and women are successfully adjusted to their environment. Their adjustment might be better, but it is good enough to keep them alive for a time. Now, if children do as they see their parents doing, they will reach a satisfactory adjustment. We may, therefore, say that the tendency to imitate serves to adjust the child to his environment. It is for this reason that imitation has been called an adaptive instinct. It would perhaps be better to say merely that the tendency to imitate is part of the original equipment of man.

Imitation is distinctively a human trait. While it occurs in lower animals it is probably not an important factor in adjusting them to their environment. But in the human race it is one of the chief factors in adjustment to environment. Imitation is one of the main factors in education. Usually the quickest way to teach a child to do a thing is to show him how.

Through imitation we acquire our language, manners, and customs. Ideals, beliefs, prejudices, attitudes, we take on through imitation. The tendency to imitate others coupled with the desire to be thought well of by others is one of the most powerful factors in producing conformity. They are the whips which keep us within the bounds of custom and conventionality. The tendency to imitate is so strong that its results are almost as certain as are those of inherited tendencies. It is almost as certain that a child will be like his parents in speech, manners, customs, superstitions, etc., as it is that he will be like them in form of body. He not only walks and talks and acts like his parents, but he thinks as they do. We, therefore, have the term social heredity, meaning the taking on of all sorts of social habits and ideals through imitation.

The part that imitation plays in the education of a child may be learned by going to a country home and noting how the boy learns to do all the many things about the farm by imitating his father, and how the girl learns to do all the housework by imitating her mother. Imitation is the basis of much of the play of children, in that their play consists in large part of doing what they see older people doing. This imitative play gives them skill and is a large factor in preparing for the work of life.

Dramatization. Dramatization is an aspect of imitation, and is a means of making ideas more real than they would otherwise be. There is nothing that leads us so close to reality as action. We never completely know an act till we have done it. Dramatization is a matter of carrying an idea out into action. Ideas give to action its greatest fullness of meaning.

Dramatic representation should, therefore, have a prominent place in the schools, particularly in the lower grades. If the child is allowed to mimic the characters in the reading lesson, the meaning of the lesson becomes fuller. Later on in the school course, dramatic representation of the characters in literature and history is a means of getting a better conception of these characters. In geography, the study of the manners and customs and occupations of foreign peoples can be much facilitated through dramatic representation. Children naturally have the dramatic tendency; it is one aspect of the tendency to imitate. We have only to encourage it and make use of it throughout the school course.

Imitation in Ideals. Imitation is of importance not only in acquiring the actions of life but also in getting our ideals. Habits of thinking are no less an aspect of our lives than are habits of acting. Our attitudes, our prejudices, our beliefs, our moral, religious, and political ideals are in large measure copied from people about us. The family and social atmosphere in which one lives is a mold in which one's mind is formed and shaped. We cannot escape the influence of this atmosphere if we would. One takes on a belief that his father has, one clings to this belief and interprets the world in the light of it. This belief becomes a part of one's nature. It is a mental habit, a way of looking at the world. It is as much a part of one as red hair or big feet or a crooked nose. Probably no other influence has so much to do with making us what we are as social beings as the influence of imitation.

Play. Play is usually considered to be a part of the original equipment of man. It is essentially an expression of the ripening instincts of children, and not a specific instinct itself. It is rather a sort of make-believe activity of all the instincts. Kittens and dogs may be seen in play to mimic fighting. They bite and chew each other as in real fighting, but still they are not fighting.

As the structures and organs of children mature, they demand activity. This early activity is called play. It has several characteristics. The main one is that it is pleasurable. Play activity is pleasurable in itself. We do not play that we may get something else which we like, as is the case with the activity which we call work. Play is an end in itself. It is not a means to get something else which is intrinsically valuable.

One of the chief values of play comes from its activity aspect. We are essentially motor beings. We grow and develop only through exercise. In early life we do not have to exert ourselves to get a living. Play is nature's means of giving our organs the exercise which they must have to bring them to maturity. Play is an expression of the universal tendency to action in early life. Without play, the child would not develop, would not become a normal human being.

All day long the child is ceaselessly active. The value of this activity can hardly be overestimated. It not only leads to healthy growth, but is a means through which the child learns himself and the world. Everything that the child sees excites him to react to it or upon it. He gets possession of it. He bites it. He pounds it. He throws it. In this way he learns the properties of things and the characteristics of forces. Through play and imitation, in a very few years the child comes to a successful adjustment in his world.

Play and imitation are the great avenues of activity in early life. Even in later life, we seldom accomplish anything great or worth while until the thing becomes play to us, until we throw our whole being into it as we do in play, until it is an expression of ourselves as play is in our childhood. The proper use of play gives us the solution of many of the problems of early education.

Play has two functions in the school: (1) Motor play is necessary to growth, development, and health. The constant activity of the child is what brings about healthy growth.

In the country it is not difficult for children to get plenty of the proper kind of exercise, but in the larger cities it is difficult. Nevertheless, opportunity for play should be provided for every child, no matter what the trouble or expense, for without play children cannot become normal human beings. Everywhere parents and teachers should plan for the play life of the children.

(2) In the primary grades play can have a large place in the actual work of the school. The early work of education is to a large extent getting the tools of knowledge and thought and work—reading, spelling, writing, correct speech, correct writing, the elementary processes of arithmetic, etc. In many ways play can be used in acquiring these tools.

One aspect of play particularly should have a large place in education; namely, the manipulative tendencies of children. This is essentially play. Children wish to handle and manipulate everything that attracts their attention. They wish to tear it to pieces and to put it together. This is nature's way of teaching, and by it children learn the properties and structures of things. They thereby learn what things do and what can be done with them. Teachers and parents should foster these manipulative tendencies and use them for the child's good. These tendencies are an aspect of curiosity. We want to know. We are unhappy as long as a thing is before us which we do not understand, which has some mystery about it. Nature has developed these tendencies in us, for without a knowledge of our surroundings we could not live. The child therefore has in his nature the basis of his education. We have but to know this nature and wisely use and manipulate it to achieve the child's education.

SUMMARY. Instincts are inherited tendencies to specific actions. They fall under the heads: individualistic, socialistic, environmental, adaptive, sexual or mating instincts. These inherited tendencies are to a large extent the foundation on which we build education. The educational problem is to control and guide them, suppressing some, fostering others. In everything we undertake for a child we must take into account these instincts.

CLASS EXERCISES

1. Make a study of the instincts of several animals, such as dogs, cats, chickens. Make a list showing the stimuli and the inherited responses.

2. Make a study of the instincts of a baby. See how many inherited responses you can observe. The simpler inherited responses are known as reflexes. The closing of the eyelids mentioned in the text is an example. How many such reflexes can you find in a child?

3. Make a special study of the fears of very young children. How many definite situations can you find which excite fear responses in all children? Each member of the class can make a list of his own fears. It may then be seen whether any fears are common to all members of the class and whether there are any sex differences.

4. Similarly, make a study of anger and fighting. What situations invariably arouse the fighting response? In what definite, inherited ways is anger shown? Do your studies and observations convince you that the fighting instinct and other inherited responses concerned with individual survival are among the strongest of inherited tendencies? Can the fighting instinct be eliminated from the human race? Is it desirable to eliminate it?

5. Make a study of children's collections. Take one of the grades and find what collections the children have made. What different objects are collected?

6. Outline a plan for using the collecting instinct in various school studies.

7. With the help of the principal of the school make a study of some specific cases of truancy. What does your finding show?

8. Make a study of play by watching children of various ages play. Make a list of the games that are universal for infancy, those for childhood, and those for youth. (Consult Johnson's Plays and Games.)

9. What are the two main functions of play in education? Why should we play after we are mature?

10. Study imitation in very young children. Do this by watching the spontaneous play of children under six. What evidences of imitation do you find?

11. Outline the things we learn by imitation. What is your opinion of the place which imitation has in our education?

12. Make a study of imitation as a factor in the lives of grown people. Consider styles, fashions, manners, customs, beliefs, prejudices, religious ideas, etc.

13. On the whole, is imitation a good thing or a bad thing?

14. Make a plan of the various ways in which dramatization can be profitably used in the schools.

15. Make a study of your own ideals. What ideals do you have? Where did you get them? What ideals did you get from your parents? What from books? What from teachers? What from friends?

16. Show that throughout life inherited tendencies are the fundamental bases from which our actions proceed, on which our lives are erected.

CHAPTER V

FEELING AND ATTENTION

The Feelings. Related to the instincts on one side and to habits on the other are the feelings. In Chapter III we discussed sensation, and in the preceding chapter, the instincts, but when we have described an act in terms of instinct and sensation, we have not told all the facts.

For example, when a child sees a pretty red ball of yarn, he reaches out to get it, then puts it into his mouth, or unwinds it, and plays with it in various ways. It is all a matter of sensation and instinctive responses. The perception of the ball—seeing the ball—brings about the instinctive reaching out, grasping the ball, and bringing it to the mouth. But to complete our account, we must say that the child is pleased. We note a change in his facial expression. His eyes gleam with pleasure. His face is all smiles, showing pleasant contentment. Therefore we must say that the child not only sees, not only acts, but the seeing and acting are pleasant. The child continues to look, he continues to act, because the looking and acting bring joy.

This is typical of situations that bring pleasure. We want them continued; we act in a way to make them continue. We go out after the pleasure-giving thing.

But let us consider a different kind of situation. A child sees on the hearth a glowing coal. It instinctively reaches out and grasps it, starts to draw the coal toward it, but instinctively drops it. This is not, however, the whole story. Instead of the situation being pleasant, it is decidedly unpleasant. The child fairly howls with pain. His face, instead of being wreathed in smiles, is covered with tears. He did not hold on to the coal. He did not try to continue the situation. On the contrary, he dropped the coal, and withdrew the hand. The body contracted and shrank away from the situation.

These two cases illustrate the two simple feelings, pleasantness and unpleasantness. Most situations in life are either pleasant or unpleasant. Situations may sometimes be neutral; that is, may arouse neither the feeling of pleasantness or unpleasantness. But usually a conscious state is either pleasant or unpleasant. A situation brings us life, joy, happiness. We want it continued and act in a way to bring about its continuance. Or the situation tends to take away our life, brings pain, sorrow, grief, and we want it discontinued, and act in a way to discontinue it.

These two simple forms of feeling perhaps arose in the beginning in connection with the act of taking food. It is known that if a drop of acid touches an amoeba, the animal shrinks, contracts, and tries to withdraw from the death-bringing acid. On the other hand, if a particle of a substance that is suitable for food touches the animal, it takes the particle within itself. The particle is life-giving and brings pleasure.

The Emotions. Pleasure and displeasure are the simple feelings. Most situations in life bring about very complex feeling states known as emotions. The emotions are made up of pleasure or displeasure mixed or compounded with the sensations from the bodily reactions.

The circulatory system, the respiratory system, and nearly all the involuntary organs of the body form a great sounding board which instantly responds in various ways to the situations of life. When the youth sees the pretty maiden and when he touches her hand, his heart pumps away at a great rate, his cheeks become flushed, his breathing is paralyzed, his voice trembles. He experiences the emotion of love. The state is complex indeed. There is pleasantness, of course, but there is in addition the feeling of all the bodily reactions.

When the mother sees her dead child lying in its casket, her head falls over on her breast, her eyes fill with tears, her shoulders droop, her chest contracts, she sobs, her breathing is spasmodic. Nearly every organ of the body is affected in one way or another. The state is unpleasant, but there is also the feeling of the manifold bodily reactions.

So it is always. The biologically important situations in life bring about, through hereditary connections in the nervous system, certain typical reactions. These reactions are largely the same for the same type of situation, and they give the particular coloring to each emotion. It is evident that the emotions are closely related to the instincts. The reflexes that take place in emotions are of the same nature as the instincts. Each instinctive act has its characteristic emotion. There are fear instincts and fear emotions. Fear is unpleasant. In addition to its unpleasantness there is a multitude of sensations that come from the body. The hair stands on end, the heart throbs, the circulation is hastened, breathing is interrupted, the muscles are tense. This peculiar mass of sensations, blended with the unpleasantness, gives the characteristic emotion of fear. But we need not go into an analysis of the various emotions of love, hate, envy, grief, jealousy, etc. The reader can do this for himself.[3]

[3] See James' Psychology, Briefer Course, Chapter XXIV.

Nearly every organ of the body plays its part in the emotions: the digestive organs, the liver, the kidneys, the throat and mouth, the salivary glands, the eyes and tear glands, the skin muscles, the facial muscles, etc. And every emotion is made up of pleasantness or unpleasantness and the sensations produced by some combination of bodily reactions.

It is well for us to remember the part that bodily conditions and states play in the emotional life. The emotional state of a man depends upon whether he has had his dinner or is hungry, whether the liver is working normally, and upon the condition of the various secreting and excreting organs and glands. In a word, it is evident that our emotions fall within a world of cause and effect. Our feeling states are caused.

Importance in Life. Our feelings and emotions are the fountains from which nearly all our volitional actions flow. Feeling is the mainspring of life. Nearly everything we do is prompted by love, or hate, or fear, or jealousy, or rivalry, or anger, or grief. If the feelings have such close relation to action, then the schools must take them into account, for by education we seek to control action. If the feelings control action, then we must try to control the feelings. We must get the child into a right state of mind toward the school, toward his teacher, and toward his work. The child must like the school, like the teacher, and want to learn.

Moreover, we must create the right state of mind in connection with each study, each task. The child must come to feel the need and importance of each individual task as well as of each subject. The task is then desirable, it is to be sought for and worked at, it is important for life.

This is merely enlisting the child's nature in the interest of his education. For motive, we must always look to the child's nature. The two great forces which pull and drive are pleasure and pain. Nature has no other methods. Formerly the school used pain as its motive almost exclusively. The child did his tasks to escape pain. For motive we now use more often the positive influences which give pleasure, which pull instead of drive. What will one not do for the loved one? What will one not do to the hated one? The child who does not love his teacher gets little good from school while under that teacher. Moreover, school work is often a failure because it is so unreal, has so little relation to an actual world, and seems foreign to any real needs of the child. No one is going to work very hard unless the work is prompted by desire. Our desires come from our needs. Therefore, if we are to enlist the child's feelings in the service of his education, we must make the school work vital and relate it, if possible, to the actual needs of the child.

It must not be forgotten, however, that we must build up permanent attitudes of respect for authority, obedience, and reverence for the important things of life. Neither must it be forgotten that we can create needs in the child. If in the education of the child we follow only such needs as he has, we will make a fine savage of him but nothing else. It is the business of the school to create in the child the right kind of needs. As was pointed out in our study of the instincts, we must make the child over again into what he ought to be. But this cannot be a sudden process. One cannot arouse enthusiasm in a six-year-old child over the beauties of higher mathematics. It takes ten or fifteen years to do that, and it must be done little by little.

Control of the Emotions. Without training, we remain at the mercy of our baser emotions. The child must be trained to control himself. Here is where habit comes in to modify primitive action. The child can be trained to inhibit or prevent the reactions that arise in hatred, envy, jealousy, anger, etc. For a fuller discussion of this point we must wait till we come to the discussion of habit and moral training.

Mood and Temperament. A mood is a somewhat extended emotional state continuing for hours or days. It is due to a continuance of the factors which cause it. The state of the liver and digestive organs may throw one for days into a cross and ugly mood. When the body becomes normal, the mood changes or disappears. Similarly, one may for hours or days be overjoyed, or depressed, or morose, or melancholy. Parents and teachers should look well to the matter of creating and establishing continuous and permanent states of feeling that are favorable to work and development.

Some people are permanently optimistic, others pessimistic. Some are always joyful, others as constantly see only the dark side of life. Some are always serious and solemn, others always gay, even giddy. These permanent emotional attitudes constitute temperament, and are due to fundamental differences within the body that are in some cases hereditary. Crossness and moroseness, for example, may be due to a dyspeptic condition and a chronically bad liver. The happy dispositions belong to bodies whose organs are functioning properly, in which assimilation is good—all the parts of the body doing their proper work.

Poor eyes which are under a constant strain, through the reflex effects upon various organs of the body, are likely to develop a permanently cross and irritable disposition. Through the close sympathetic relation of the various organs, anything affecting one organ and interfering with its proper action is likely to affect many other organs and profoundly influence the emotional states of the body. In growing children particularly, there are many influences which affect their emotions, things of which we seldom think, such as the condition of vision and hearing, the condition of the teeth, nose, and throat, and the condition of all the important vital organs of the body. When a child's disposition is not what we think it ought to be, we should try to find out the causes.

Training the Emotions. The emotions are subject to training. The child can be taught control. Moreover, he can be taught to appreciate and enjoy higher things than mere animal pleasure; namely, art, literature, nature, truth. The child thereby becomes a spiritual being instead of a mere pig. The ideal of the school should be to develop men and women whose baser passions are under control, who are calm, self-controlled, and self-directed, and who get their greatest pleasure from the finer and higher things of life, such as the various forms of music, the songs of birds, the beauties and intricate workings of nature.

This is a wonderful world and a wonderful life, but the child may go through the world without seeing it, and live his life without knowing what it is to live. His eyes must be opened, he must be trained to see and to feel. It is not the place here to tell how this is to be done. This is not a book on methods of teaching. We can only indicate here that the business of the school is not merely to teach people how to make a living, but to teach them how to enjoy the living. There are many avenues from which we get the higher forms of pleasure. There are really many different worlds which we may experience: the world of animals, the world of plants, the mechanical world, the chemical world, the world of literature and of art, the world of music. It is the duty of the schools to open up these worlds to the children, and make them so many possibilities of joy and happiness.

The emotions and feelings, then, are not lawless and causeless, but are a part of a world of law and order. They are themselves caused and therefore subject to control and modification.

Attention. Attention, too, is related to inherited tendencies on the one side and to habits on the other. If one is walking in the woods and catches a glimpse of something moving in the trees, the eyes instinctively turn so that the person can get a better view of the object. If one hears a sudden sound, the head is instinctively turned so that the person can hear better. One stops, the body is held still and rigid, breathing is slow and controlled—all to favor better hearing.

The various acts of attention are reflex and instinctive. But what is attention? By attention we mean sensory clearness. When we say we are attentive to a thing or subject, we mean that perceptions or ideas of that thing or subject are clear as compared to other perceptions and ideas that are in consciousness at the same time. The contents of one's consciousness, the perceptions and ideas that constitute one's mind at any one moment are always arranged in an attentive pattern, some being clear, others unclear. The pattern constantly changes and shifts. What is now clear and in the focus of consciousness, presently is unclear and may in a moment disappear from consciousness altogether, while other perceptions or ideas take its place.

The first question that arises in connection with attention is, What are the causes of attention? The first group of causes are hereditary and instinctive. The child attends to loud things, bright things, moving things, etc. But as we grow older, the basis of attention becomes more and more habit. An illustration will make this clear. I once spent a day at a great exposition with a machinist. He was constantly attending to things mechanical, when I would not even see them. He had spent many years working with machinery, and as a result, things mechanical at once attracted him. Similarly, if a man and a woman walk along a street together and look in at the shop windows, the woman sees only hats, dresses, ribbons, and other finery, while the man sees only cigars, pipes, and automobile supplies. Every day we live, we are building up habits of attending to certain types of things. What repeatedly comes into our experience, easily attracts our attention to the exclusion of other things.

The Function of Attention. Attention is the unifying aspect of consciousness. There are always many things in consciousness, and we cannot respond to all at once. The part of consciousness that is clear and focal brings about action. The things to which we attend are the things that count.

In later chapters we shall learn that in habit-formation, attention is an important factor. We must attend to the acts we are trying to make habitual. In getting knowledge, we must attend to what we are trying to learn. In committing to memory, we must attend to the ideas that we are trying to fix and make permanent. In thinking and reasoning, those ideas become associated together that are together in attention.

Attention is therefore the controlling aspect of consciousness. It is the basis of what we call will. The ideas that are clear and focal and that persist in consciousness are the ideas that control our action. When one says he has made up his mind, he has made a choice; that merely means that a certain group of ideas persist in consciousness to the exclusion of others. These are the ideas which ultimately produce action. And it is our past experience that determines what ideas will become focal and persist.

Training the Attention. There are two aspects of the training of attention. (1) We can learn to hold ourselves to a task. When we sit down to a table to study, there may be many things that tend to call us away. There lies a magazine which we might read, there is a play at the theater, there are noises outside, there is a friend calling across the street. But we must study. We have set ourselves to a task and we must hold fast to our purpose.

The young child cannot do this. He must be trained to do it. The instruments used to train him are pleasure and pain, rewards and punishments that come from parents. Gradually, slowly, the child gains control over himself. No one ever amounts to anything till he can hold himself to a task, to a fixed purpose. One must learn to form plans extending over weeks, months, and years, and to hold unflinchingly to them, just as one must hold himself to his study table and allow nothing to distract or to interfere. No training a child can receive is more important than this, for it gives him control over his life, it gives him control over the ideas that are to become focal and determine action. It is for this reason that we call such training a training of attention. It might perhaps better be called a training of the will. But the will is only the attentive consciousness. The idea that is clear, that holds its own in consciousness, is the idea that produces action. When we say that we will to do a certain thing, all we can mean is that the idea of this act is clearest and holds its focal place in consciousness to the exclusion of other ideas. It therefore goes over into action.

(2) The training just discussed may be called a general training of attention giving us a general power and control over our lives, but there is another type of training which is specific. As with the machinist mentioned above, so with all of us; we attend to the type of thing that we have formed a habit of attending to. Continued experience in a certain field makes it more and more easy to attend to things in that field. One can take a certain subject and work at it day after day, year after year. By and by, the whole world takes on the aspect of this chosen subject. The entomologist sees bugs everywhere, the botanist sees only plants, the mechanic sees only machines, the preacher sees only the moral and religious aspects of action, the doctor sees only disease, the mathematician sees always the quantitative aspect of things. Ideas and perceptions related to one's chosen work go at once and readily to the focus of consciousness; other things escape notice.

It is for this reason that we become "crankier" every year that we live. We are attending to only one aspect of the world. While this blinds us to other aspects of the world, it brings mastery in our individual fields. We can, then, by training and practice, get a general control over attention, and by working in a certain field or kind of work, we make it easy to attend to things in that field or work. This to an extent gives us control of our lives, of our destiny.

Interest. The essential elements of interest are attention and feeling. When a person is very attentive to a subject and gets pleasure from experience in that subject, we commonly say that he is interested in that subject.

Since the importance of attention and feeling in learning has already been shown and will be further developed in the chapters which follow in connection with the subjects of habit, memory, and thinking, little more need be said here.

The key to all forms of learning is attention. The key to attention is feeling. Feeling depends upon the nature of the child, inherited and acquired. In our search for the means of arousing interest, we look first to the original nature of the child, to the instincts and the emotions. We look next to the acquired nature, the habits, the ideals, the various needs that have grown up in the individual's life. Educational writers have overemphasized the original nature of the child as a basis of interest and have not paid enough attention to acquired nature. We should not ask so much what a child's needs are, but what they ought to be. Needs can be created. The child's nature to some extent can be changed. The problem of arousing interest is therefore one of finding in the child's nature a basis for attention and pleasure. If the basis is not to be found there, then it must be built up. How this can be done, how human nature can be changed, is to some extent the main problem of psychology. Every chapter in this book, it is hoped, will be found to throw some light on the problem.

SUMMARY. The two elementary feeling states are pleasantness and unpleasantness. The emotions are complex mental states composed of feeling and the sensations from bodily reactions to the situations. Feeling and emotion are the motive forces of life, at the bottom of all important actions. The bodily reactions of emotions are reflex and instinctive. Attention is a matter of the relative clearness of the contents of consciousness. The function of attention is to unify thought and action. It is the important factor in all learning and thinking, for it is only the attentive part of consciousness that is effective.

CLASS EXERCISES

1. Make out a complete list of the more important emotions.

2. Indicate the characteristic expression of each emotion in your list.

3. Can you have an emotion without its characteristic expression? If, for example, when a situation arises which ordinarily arouses anger in you, you inhibit all the usual motor accompaniments of anger, are you really angry?

4. Are the expressions of the same emotion the same for all people?

5. Try to analyze some of your emotional states: anger, or fear, or grief. Can you detect the sensations that come from the bodily reactions?

6. Try to induce an emotional state by producing its characteristic reactions.

7. Try to change an emotional state to an opposite emotion; for example, grief to joy.

8. Try to control and change emotional states in children.

9. Name some sensations that for you are always pleasant, others that are always unpleasant—colors, sounds, tastes, odors, temperatures.

10. Confirm by observation the statement of the text as to the importance of emotions in all the important actions of life.

11. To what extent do you have control of your emotional states? What have you observed about differences in expression of deep emotions by different people? In case of death in the family, some people wail and moan and express their grief in the most extreme manner, while others do not utter a sound and show great control. Why the difference?

12. Make an introspective study of your conscious states to note the difference in clearness of the different processes that are going on in consciousness. Do you find a constant shifting?

13. Perform experiments to show the effects of attention in forming habits and acquiring knowledge.

(1) Perform tests in learning, using substitution tests as described in Chapter X. Use several different keys. In some experiments have no distractions, in others, have various distracting noises. What differences do you find in the results?

(2) Try learning nonsense syllables, some lists with distractions, others without distractions.

(3) Try getting the ideas from stories read to you, as in the logical memory experiment described in Chapter X. Some stories should be read without distractions, others with distractions.

14. Why are you unable to study well when under the influence of some strong emotion?

15. Are you trained to the extent that you can concentrate on a task and hold yourself to it for a long time?

16. Do you see that as far as will and attention and the emotions are concerned, your life and character are in large measure in your own hands?

17. Make a complete outline of the chapter.

CHAPTER VI

HABIT

The Nature of Habit. We now turn from man's inherited nature to his acquired nature. Inherited tendencies to action we have called instincts; acquired tendencies to action we shall call habits. We can best form an idea of the nature of habit by considering some concrete cases.

Let us take first the case of a man forming the habit of turning out the basement light. It usually happens that when a man has an electric light in the basement of his house, it is hard for him at first to think to turn out the light at night when he retires, and as a consequence the light often burns all night. This is expensive and unnecessary, so there is a strong incentive for the man to find a plan which will insure the regular turning-off of the light at bedtime. The plan usually hit upon is the following: The electric switch that controls the basement light is beside the basement stairway. The man learns to look at the switch as he comes up the stairs, after preparing the furnace fire for the night, and learns to take hold of the switch when he sees it and turn off the light. Coming up the stairs means to look at the switch. Seeing the switch means to turn it. Each step of the performance touches off the next. The man sees that in order to make sure that the light will always be turned off, the acts must all be made automatic, and each step must touch off the next in the series. At first, the man leaves the light burning about as often as he turns it off. After practicing for a time on the scheme, the different acts become so well connected that he seldom leaves the light burning. We say that he has formed the habit of turning off the light.

For a second illustration, let us take the process of learning that nine times nine equals eighty-one. At first, one does not say or write "eighty-one" when one sees "nine times nine," but one can acquire the habit of doing so. It does not here concern us how the child learns what the product of nine times nine is. He may learn it by counting, by being told, or by reading it in a book. But however he first learns it, he fixes it and makes it automatic and habitual by continuing to say or to write, "nine times nine equals eighty-one." The essential point is that at first the child does not know what to say when he hears or sees the expression "nine times nine," but after long practice he comes to give automatically and promptly the correct answer. For the definite problem "nine times nine" there comes the definite response "eighty-one."

For a third illustration, let us take the case of a man tipping his hat when he meets a lady. A young boy does not tip his hat when he meets a lady until he has been taught to do so. After he learns this act of courtesy he does it quite automatically without thinking of it. For the definite situation, meeting a lady of his acquaintance, there comes to be established the definite response, tipping the hat. A similar habit is that of turning to the right when we meet a person. For the definite situation, meeting a person on the road or street or sidewalk, there is established the definite response, turning to the right. The response becomes automatic, immediate, certain.

There is another type of habit that may properly be called an intellectual habit, such as voting a certain party ticket, say the Democratic. When one is a boy, one hears his father speak favorably of the Democratic party. His father says, "Hurrah for Bryan," so he comes to say, "Hurrah for Bryan." His father says, "I am a Democrat," so he says he is a Democrat. He takes the side that his father takes. In a similar way we take on the same religious notions that our parents have. It does not always happen this way, but this is the rule. But no matter how we come to do it, we do adopt the creed of some party or some church. We adopt a certain way of looking at public questions, and a certain way of looking at religious questions. For certain rather definite situations, we come to take definite stands. When we go to the booth to vote, we look at the top of the ballot to find the column marked "Democratic," and the definite response is to check the "Democrat" column. Of course, some of us form a different habit and check the "Republican" column, but the psychology of the act is the same. The point is that we form the Democratic habit or we form the Republican habit; and the longer we practice the habit, the harder it is to change it.

In the presidential campaign of 1912, Roosevelt "bolted" from the Republican party. It was hard for the older Republicans to follow him. While one occasionally found a follower of Roosevelt who was gray, one usually found the old Republicans standing by the old party, the younger ones joining the Progressive party. It is said that when Darwin published "The Origin of Species," very few old men accepted the doctrine of evolution. The adherents of the new doctrine were nearly all young men. So there is such a thing as an intellectual habit. One comes to take a definite stand when facing certain definite intellectual situations.

Similar to the type of habits which we have called intellectual is another type which may be called "moral." When we face the situation of reporting an occurrence, we can tell the truth or we can lie. We can build up the habit of meeting such situations by telling the truth on all occasions. We can learn to follow the maxim "Tell the truth at all times, at all hazards." We can come to do this automatically, certainly, and without thought of doing anything else.

Most moral situations are fairly definite and clear-cut, and for them we can establish definite forms of response. We can form the habit of helping a person in distress, of helping a sick neighbor, of speaking well of a neighbor; we can form habits of industry, habits of perseverance. These and other similar habits are the basis of morality.

The various kinds of habits which we have enumerated are alike in certain fundamental particulars. In all of them there is a definite situation followed by a definite response. One sees the switch and turns off the light; he sees the expression "nine times nine" and says "eighty-one"; he sees a lady he knows and tips his hat; in meeting a carriage on the road, he turns to the right; when he has to vote, he votes a certain ticket; when he has to report an occurrence, he tells it as it happened. There is, in every case, a definite situation followed by a definite response.

Another characteristic is common to all the cases mentioned above, i.e. the response is acquired, it does not come at first. In every instance we might have learned to act differently. We could form the habit of always leaving the light burning; could just as easily say "nine times nine equals forty"; we could turn to the left; we could vote the Republican ticket. We can form bad moral habits as well as good ones, perhaps more easily. The point is, however, that we acquire definite ways of acting for the same situations, and these definite ways of acting are called habits.

Habit and Nerve-Path. It has already been stated that a habit is a tendency toward a certain type of action in a certain situation. The basis of this tendency is in the nervous system. In order to understand it we must consider what the nervous system is like. Nerves terminate at one end in a sense organ and at the other end ultimately in a muscle.

In Figure II, A is a sense organ, B a nerve going from the sense organ to the brain C. D, E, F, G, and H are motor nerves going from the brain to the muscles. Now, let us show from the diagram what organization means and what tendency means. At first when the child sees the expression "nine times nine," he does not say "eighty-one." The stimulus brings about no definite action. It is as likely to go out through E or F as through D. But suppose we can get the child to say "nine times nine equals eighty-one." We can write the expression on the blackboard and have the child look at it and say "nine times nine equals eighty-one." Suppose the act of saying "eighty-one" is brought about by the nerve-current going out through nerve-chain D. By repetition, we establish a bond. A stimulus of a particular kind comes through A, goes over B to C, and out over D, making muscles at M bring about a very definite action in saying "eighty-one."



From the point of view of physiology, the process of habit-formation consists in securing a particular nerve coupling, establishing a particular nerve path, so that a definite form of stimulation will bring about a definite form of response. A nerve tendency is simply the likelihood that a stimulus will take a certain course rather than any other. This likelihood is brought about by getting the stimulus to take the desired route through the nervous system to a group of muscles and to continue following this route. The more times it passes the same way, the greater is the probability that at any given time the stimulus will take the accustomed route and bring about the usual response. At first any sort of action is possible. A nerve stimulus can take any one of the many routes to the different muscles. By chance or by conscious direction, the stimulus takes a certain path, and by repetition we fix and make permanent this particular route. This constitutes a nerve tendency or habit.

Plasticity. Our discussion should have made it clear that habit is acquired nature, while instinct is inherited nature. Habit is acquired tendency while instinct is inherited tendency. The possibility of acquiring habits is peculiarly a human characteristic. While inanimate things have a definite nature, a definite way of reacting to forces which act upon them, they have little, if any, possibility of varying their way of acting. Water might be said to have habits. If one cools water, it turns to ice. If we heat it, it turns to steam. But it invariably does this. We cannot teach it any different way of acting. Under the same conditions it always does the same thing.

Plants are very much like inanimate things. Plants have definite ways of acting. A vine turns around a support. A leaf turns its upper surface to the light. But one cannot teach plants different ways of acting. The lower forms of animals are somewhat like plants and inanimate objects. But to a very slight extent they are variable and can form habits. Among the higher animals, such as dogs and other domestic animals, there is a greater possibility of forming habits. In man there are the greatest possibilities of habit-formation. In man the learned acts or habits are many as compared to the unlearned acts or instincts; while among the lower animals the opposite is the case—their instincts are many as compared to their habits.

We may call this possibility of forming habits plasticity. Inanimate objects such as iron, rocks, sulphur, oxygen, etc., have no plasticity. Plants have very little possibility of forming habits. Lower animals have somewhat more, and higher animals still more, while man has the greatest possibility of forming habits. This great possibility of forming habits is one of the main characteristics of man. Let us illustrate the contrast between man and inanimate objects by an example. If sulphur is put into a test tube and heated, it at first melts and becomes quite thin like water. If it is heated still more, it becomes thick and will not run out of the tube. It also becomes dark. Sulphur always does this when so treated. It cannot be taught to act differently. Now the action of sulphur when heated is like the action of a man when he turns to the right upon meeting a person in the street. But the man has to acquire this habit, while the sulphur does not have to learn its way of acting. Sulphur always acted in this way, while man did not perform his act at first, but had to learn it by slow repetition.

Everything in the world has its own peculiar nature, but man is unique in that his nature can be very much changed. To a large extent, a man is made, his nature is acquired. After we become men and women, we have hundreds and thousands of tendencies to action, definite forms of action, that we did not have when young. Man's nature might be said to consist in his tendencies to action. Some of these tendencies he inherits; these are his instincts. Some of these he acquires; these are his habits.

What Habits Do for Us. We have found out what habits are like; let us now see what they do for us. What good do they accomplish for us? How are we different after forming a habit from what we were before? We can best answer these questions by a consideration of concrete cases. Typewriting will serve very well the purpose of illustration. We shall give the result of an actual experiment in which ten university students took part. During their first half hour of practice, they wrote an average of 120 words. At the end of forty-five hours of practice, they were writing an average of 680 words in a half hour. This was an increase of speed of 560 per cent. An expert typist can write about 3000 words in a half hour. Such a speed requires much more than forty-five hours practice, and is attained by the best operators only.



In the foregoing experiment, the students improved in accuracy also. At the beginning of the work, they made 115 errors in the half hour. At the end of the practice, with much faster speed, they were making only 327 errors in a half hour. The actual number of errors had increased 280 per cent. The increase in errors was therefore exactly half as much as the increase in speed. This, of course, was a considerable increase in accuracy, for while the speed had increased to 5.6 times what it had been at the beginning, the errors had increased only 2.8 times. The subjects in this experiment paid much more attention to speed than they did to accuracy. If they had emphasized accuracy, they would have been doing almost perfect work at the end of the practice, and their speed would have been somewhat less. Practice, then, not only develops speed but also develops accuracy.

There are also other results. At the beginning of work with the typewriter, there is much waste of energy and much fatigue. The waste of energy comes from using unnecessary muscles, and the fatigue is partly due to this waste of energy. But even apart from this waste of energy, an habituated act is performed with less fatigue. The various muscles concerned become better able to do their work. As a result of habituation there is, then, greater speed, greater accuracy, less waste of energy, and less fatigue.

If we look not at the changes in our work but at the changes in ourselves, the changes in our minds due to the formation of habits, we find still other results. At the beginning of practice with the typewriter, the learner's whole attention is occupied with the work. When one is learning to do a new trick, the attention cannot be divided. The whole mind must be devoted to the work. But after one has practiced for several weeks, one can operate the typewriter while thinking about something else. We say that the habituated act sinks to a lower level of consciousness, meaning that as a habit becomes more and more fixed, less and less attention is devoted to the acts concerned.

Increased skill gives us pleasure and also gives us confidence in our ability to do the thing. Corresponding to this inner confidence is outer certainty. There is greater objective certainty in our performance and a corresponding inner confidence. By objective certainty, we mean that a person watching our performance, becomes more and more sure of our ability to perform, and we ourselves feel confidence in our power of achievement.

Now that we have shown the results of habituation let us consider additional illustrations. In piano playing, the stimuli are the notes as written in the music. We see the notes occupying certain places on the scale of the music. A note in a certain place means that we must strike a certain key. At first the response is slow, we have to hunt out each note on the keyboard. Moreover, we make many mistakes; we strike the wrong keys just as we do in typewriting. We are awkward, making many unnecessary movements, and the work is tiresome and fatiguing. After long practice, the speed with which we can manipulate the keys in playing the piano is wonderful. Our playing becomes accurate, perfect. We do it with ease, with no unnecessary movements. We can play the piano, after we become skilled, without paying attention to the actual movements of our hands. We can play the piano while concentrating upon the meaning of the music, or while carrying on a conversation, or while thinking about something else. As a rule, pleasure and confidence come with skill. Playing a difficult piece on the piano involves a skill which is one of the most complicated that man achieves. It is possible only through habituation of the piano-playing movements.

Nailing shingles on a roof illustrates well the various aspects of habituation. The expert carpenter not only nails on many more shingles in a day than does the amateur, but he does it better and with more ease, and with much less fatigue. The carpenter knows exactly how much he can do in a day, and each particular movement is certain and sure. The carpenter has confidence in, and usually prides himself on, this ability, thus getting pleasure out of his work.

The operations in arithmetic illustrate most of the results of habituation. Practice in addition makes for speed and accuracy. In a few weeks' time we can very much increase our speed and accuracy in adding, or in the other arithmetical operations.

The foregoing examples are sufficient, although they could be multiplied indefinitely. Almost any habit one might name would show clearly most of the results enumerated. The most important aspects of habituation may be summed up in the one word efficiency. Habituation gives us speed and accuracy. Speed and accuracy mean skill. Skill means efficiency.

How Habits Are Formed. It is clear from the foregoing discussion that the essential thing in a habit is the definiteness of the connection between the stimulus and the response, between the situation and the reaction to the situation. Our question now is, how is this definiteness of connection established? The answer is, through repetition. Let us work the matter out from a concrete case, such as learning to play the piano. In piano playing the stimulus comes from the music as printed on the staff. A note having a certain position on the staff indicates that a certain key is to be struck. We are told by our music teacher what keys on the piano correspond to the various notes on the staff, or we may learn these facts from the instruction book. It makes no difference how we learn them; but after we know these facts, we must have practice to give us skill. The mere knowledge will not make us piano players. In order to be skillful, we must have much practice not only in striking the keys indicated by the various note positions, but with the various combinations of notes. For example, a note on the second space indicates that the player must strike the key known as "A." But "A" may occur with any of the other notes, it may precede them or it may follow them. We must therefore have practice in striking "A" in all these situations. To have skill at the piano, we must mechanize many performances. We must be able to read the notes with accuracy and ease. We must practice so much that the instant we see a certain combination of notes on the staff, our hands immediately execute the proper strokes. Not only must we learn what keys on the piano correspond to the various notes of the music, but the notes have a temporal value which we must learn. Some are to be sounded for a short time, others for a longer time. We have eighth notes, quarter notes, half notes, etc. Moreover, the signature of the music as indicated by the sharps or flats changes the whole situation. If the music is written in "A sharp" then when "A" is indicated on the staff, we must not strike the white key known as "A," but the black key just above, known as "A sharp."

Briefly, in piano playing, the stimulus comes from the characters printed on the staff. The movements which these characters direct are very complicated and require months and years of practice. We must emphasize the fact that practice alone gives facility, years of practice. But after these years of practice, one can play a piece of music at sight; that is, the first stimulus sets off perfectly a very complicated response. This sort of performance is one of the highest feats of skill that man accomplishes.

To get skill, then, one must practice. But mere repetition is not sufficient. For practice to be most effective, one must put his whole mind on what he is doing. If he divides his attention between the acts which he is practicing and something else, the effect of the practice in fixing and perfecting the habit is slight. It seems that when we are building up a new nerve-path which is to be the basis of a new habit, the nervous energies should not be divided; that the whole available nervous energy should be devoted to the acts which we are repeating. This is only another way of saying that when we are practicing to establish a habit, we should attend to what we are doing and to nothing else. But after the habit-connection is once firmly established, we can attend to other things while performing the habitual act. The habitual action will go on of itself. We may say, then, that in order to be able to do a thing with little or no attention, we must give much attention to it at first.

Another important factor in habit-formation is pleasure. The act which we are practicing must give us pleasure, either while we are doing it or as a result. Pleasurable results hasten habit-formation. When we practice an act in which we have no interest, we make slow progress or none at all. Now the elements of interest are attention and pleasure. If we voluntarily attend to a thing and its performance gives us pleasure, or pleasure results from it, we say we are interested in it. The secret of successful practice is interest. Repeatedly in laboratory experiments it happens that a student loses interest in the performance and subsequently makes little, if any, progress. One of the biggest problems connected with habit-formation is that of maintaining interest.
