The Story of the Mind Part 3

In another place below I a.n.a.lyze a child's game and draw some inferences from it. Here it may suffice to say that in their games the young animals acquire the flexibility of mind and muscle upon which much of the social co-operation, as well as the individual effectiveness, of their later life depends. With children, it is not the only agency, of course, though its importance is not less. We have to carry the children further by other means; but the other means should never interfere with this natural schooling. They should aim the rather by supplementing it wisely to direct its operation and to extend its sphere.

CHAPTER IV.

THE MIND OF THE CHILD--CHILD PSYCHOLOGY.

One of the most interesting chapters of modern psychology is that which deals with the child. This is also one of the topics of general concern, since our common humanity reacts with greater geniality upon the little ones, in whom we instinctively see innocence and simplicity. The popular interest in children has been, however--as uncharitable as it may seem to say it--of very little service to the scientific investigation of childhood. Even to-day, when a greater body of valuable results are being secured, the main danger to the proper study of the child's mind comes from the over-enthusiasm and uninstructed a.s.surance of some of its friends. Especially is this the case in America, where "child study" has become a fad to be pursued by parents and teachers who know little about the principles of scientific method, and where influential educators have enlisted so-called "observers" in taking indiscriminate notes on the doings of children with no definite problem in view, and with no criticism of their procedure. It is in place, therefore, to say clearly, at the outset, that this chapter does not mean to stimulate parents or unpsychological readers to report observations; and further to say also that in the mind of the writer the publications made lately of large numbers of replies to "syllabi" are for the most part worthless, because they heap together observations obtained by persons of every degree of competence and incompetence.

On the other hand, the requisites here, as in every other sphere of exact observation, are clear enough. The student of the child's mind should have a thorough knowledge of the principles of general psychology, in order to know what is characteristic of the child when he sees it, and what is exceptional; and he should also have enough originality in his ideas and interpretations to catch the valuable in the child's doings, distinguis.h.i.+ng it from the commonplace, and to plan situations and even experiments which will give him some control upon those actions of the child which seem to be worth it. The need of these qualities is seen in the history of the problems of the child's growth which have been taken up even by the most competent psychologists. The results show a gradual attainment of control over the problem in hand, each observer criticising the method and results of his predecessor until certain rules of observation and experiment have been evolved which allow of the repet.i.tion and repeated observation of the events of the child's life.

As ill.u.s.trating the sort of problems in which there has been this careful and critical work, I may instance these: the child's reflex movements, the beginnings and growth of sensation, such as colour, the rise of discrimination and preference, the origin of right and left-handedness, the rise, mechanism, and meaning of imitation, the acquisition of speech and handwriting, the growth of the child's sense of personality and of his social consciousness, and the laws of physical growth, as bearing upon mental development. In all these cases, however, there is again a greater and a less exactness. The topics with the reports of results which I am going on to give may be taken, however, as typical, and as showing the direction of complete knowledge rather than as having in any one case approached it.

Before we take up particular questions, however, a word may be allowed upon the general bearings of the study of the child's mind. I do this the more willingly, since it is still true, in spite of the hopeful outlook for positive results, that it is mainly the willingness of psychology to recognise the problems and work at them that makes the topic important at present. To investigate the child by scientific methods is really to bring into psychology a procedure which has revolutionized the natural sciences; and it is destined to revolutionize the moral sciences by making them also in a great measure natural sciences. The new and important question about the mind which is thus recognised is this: _How did it grow?_ What light upon its activity and nature can we get from a positive knowledge of its early stages and processes of growth? This at once introduces other questions: How is the growth of the child related to that of the animals?--how, through heredity and social influences, to the growth of the race and of the family and society in which he is brought up?

All this can be comprehended only in the light of the doctrine of evolution, which has rejuvenated the sciences of life; and we are now beginning to see a rejuvenation of the sciences of mind from the same point of view. This is what is meant when we hear it said that psychology is becoming "genetic."

The advantages to be derived from the study of young children from this point of view may be briefly indicated.

1. In the first place, the facts of the infant consciousness are very simple; that is, they are the child's sensations or memories simply, not his own observations of them. In the adult mind the disturbing influence of self-observation is a matter of notorious moment. It is impossible for me to report exactly what I feel, for the observation of it by my attention alters its character. My volition also is a complex thing, involving my personal pride and self-consciousness. But the child's emotion is as spontaneous as a spring. The effects of it in the mental life come out in action, pure and uninfluenced by calculation and duplicity and adult reserve. There is around every one of us adults a web of convention and prejudice of our own making. Not only do we reflect the social formalities of our environment, and thus lose the distinguis.h.i.+ng spontaneities of childhood, but each of us builds up his own little world of seclusion and formality with himself. We are subject, as Bacon said, not only to "idols of the forum," but also to "idols of the den."

The child, on the contrary, has not learned his own importance, his pedigree, his beauty, his social place, his religion; he has not observed himself through all these and countless other lenses of time, place, and circ.u.mstance. He has not yet turned himself into an idol nor the world into a temple; and we can study him apart from the complex accretions which are the later deposits of his self-consciousness.

2. The study of children is often the only means of testing the truth of our a.n.a.lyses. If we decide that a certain mental state is due to a union of simpler elements, then we may appeal to the proper period of child life to see the union taking place. The range of growth is so enormous from the infant to the adult, and the beginnings of the child's mental life are so low in the scale, in the matter of mental endowment, that there is hardly a question of a.n.a.lysis now under debate in psychology which may not be tested by this method.

At this point it is that child psychology is more valuable than the study of the mind of animals. The latter never become men, while children do. The animals represent in some few respects a branch of the tree of growth in advance of man, while being in many other respects very far behind him. In studying animals we are always haunted by the fear that the a.n.a.logy from him to man may not hold; that some element essential to the development of the human mind may not be in the animal at all. Even in such a question as the localization of the functions of the brain described later on, where the a.n.a.logy is one of comparative anatomy and only secondarily of psychology, the monkey presents a.n.a.logies with man which dogs do not.

But in the study of children we may be always sure that a normal child has in him the promise of a normal man.

3. Again, in the study of the child's mind we have the added advantage of a corresponding simplicity on the bodily side; we are able to take account of the physiological processes at a time when they are relatively simple--that is, before the nervous system has grown to maturity. For example, psychology used to hold that we have a "speech faculty," an inborn mental endowment which is incapable of further a.n.a.lysis; but support for the position is wanting when we turn to the brain of the infant. Not only do we fail to find the series of centres now known to be the "speech zone," but even those of them which we do find have not yet taken up this function, either alone or together. In other words, the primary object of each of the various centres involved is not speech, but some other and simpler function; and speech arises by development from a union of these separate functions.

4. In observing young children, a more direct application of experiment is possible. By "experiment" here I mean both experiment on the senses and also experiment directly on consciousness by suggestion, social influence, etc. In experimenting on adults, great difficulties arise through the fact that reactions--such as performing a voluntary movement when a signal is heard, etc.--are complicated by deliberation, habit, custom, choice, etc. The subject hears a sound, identifies it, and presses a b.u.t.ton--_if he choose_ and agree to do so. What goes on in this interval between the advent of the incoming nerve process and the discharge of the outgoing nerve process?

Something, at any rate, which represents a brain process of great complexity. Now, anything that fixes or simplifies the brain process, in so far gives greater certainty to the results. For this reason experiments on reflex actions are valuable and decisive where similar experiments on voluntary actions are uncertain and of doubtful value.

Now the child's mind is relatively simple, and so offers a field for more fruitful experiment; this is seen in the reactions of the infant to strong stimuli, such as bright colours, etc., as related further on.

With this inadequate review of the advantages of infant psychology, it is well also to point out the dangers of the abuse of it. Such dangers are real. The very simplicity which seems to characterize the life of the child is often extremely misleading, and this because the simplicity in question is sometimes ambiguous. Two actions of the child may appear equally simple; but one may be an adaptive action, learned with great pains and really very complex, while the other may be inadaptive and really simple. Children differ under the law of heredity very remarkably, even in the simplest manifestations of their conscious lives. It is never safe to say without qualification: "This child did, consequently all children must." The most we can usually say in observing single children is: "This child did, consequently another child may."

Speaking more positively, the following remarks may be useful to those who have a mind to observe children:

1. In the first place, we can fix no absolute time in the history of the child at which a certain mental process takes its rise. The observations, now quite extensively recorded, and sometimes quoted as showing that the first year, or the second year, etc., brings such and such developments, tend, on the contrary, to show that such divisions do not hold in any strict sense. Like any other organic growth, the nervous system may develop faster under more favourable conditions, or more slowly under less favourable; and the growth of the mind is largely dependent upon the growth of the brain. Only in broad outline and within very wide limits can such periods be marked off at all.

2. The possibility of the occurrence of a mental state at a particular time must be distinguished from its necessity. The occurrence of a single clearly observed fact is decisive only against the theory according to which its occurrence under the given conditions may not occur. For example, the very early adaptive movements of the infant in receiving its food can not be due to intelligence and will; but the case is still open as to the question what is the reason of their presence--i.e., how much nervous development is present, how much experience is necessary, etc. It is well to emphasize the fact that one case may be decisive in overthrowing a theory, but the conditions are seldom simple enough to make one case decisive in establis.h.i.+ng a theory.

3. It follows, however, from the principle of growth itself that the order of development of the main mental functions is constant, and normally free from great variations; consequently, the most fruitful observations of children are those which show that such an act was present _before another_. The complexity becomes finally so remarkable that there seems to be no before or after at all in mental things; but if the child's growth shows a stage in which any process is clearly absent, we have at once light upon the laws of growth. For instance: if a single case is conclusively established of a child's drawing an inference before it begins to use words or significant vocal sounds, the one case is as good as a thousand to show that thought may develop in some degree independently of spoken language.

4. While the most direct results are acquired by systematic experiments with a given point in view, still general observations carefully recorded by competent persons, are important for the interpretation which a great many such records may afford in the end.

In the mult.i.tude of experiences here, as everywhere, there is strength. Such observations should cover everything about the child--his movements, cries, impulses, sleep, dreams, personal preferences, muscular efforts, attempts at expression, games, favourites, etc.--and should be recorded in a regular daybook at the time of occurrence. What is important and what is not, is, as I have said, something to be learned; and it is extremely desirable that any one contemplating such observations should acquaint himself beforehand with the principles of general psychology and physiology, and should seek also the practical advice of a trained observer.

As yet many of the observations which we have in this field were made by the average mother, who knows less about the human body than she does about the moon or the wild flowers, or by the average father, who sees his child for an hour a day, when the boy is dressed up, and who has never slept in the same room with him--let alone the same bed!--in his life; by people who have never heard the distinction between reflex and voluntary action, or that between nervous adaptation and conscious choice. The difference between the average mother and the good psychologist is this: she has no theories, he has; he has no interests, she has. She may bring up a family of a dozen and not be able to make a single trustworthy observation; he maybe able, from one sound of one yearling, to confirm theories of the neurologist and educator, which are momentous for the future training and welfare of the child.

As for experimenting with children, only the psychologist should undertake it. The connections between the body and the mind are so close in infancy, the mere animal can do so much to ape reason, and the child is so helpless under the leading of instinct, impulse, and external necessity, that the task is excessively difficult--to say nothing of the extreme delicacy and tenderness of the budding tendrils of the mind. But others do experiment! Every time we send a child out of the home to the school, we subject him to experiment of the most serious and alarming kind. He goes into the hands of a teacher who is often not only not wise unto the child's salvation, but who is, perchance, a machine for administering a single experiment to an infinite variety of children. It is perfectly certain that a great many of our children are irretrievably damaged or hindered in their mental and moral development in the school; but we can not be at all sure that they would fare any better if they were taught at home! The children are experimented with so much and so unwisely, in any case, that possibly a little intentional experiment, guided by real insight and psychological information, would do them good.

_Methods of experimenting with Children._--In endeavouring to bring such questions as the degree of memory, recognition, a.s.sociation, etc., present in an infant, to a practical test, considerable embarra.s.sment has always been experienced in understanding the child's vocal and other responses. Of course, the only way a child's mind can be studied is through its expressions, facial, lingual, vocal, muscular; and the first question--i.e., What did the infant do? must be followed by a second--i.e., What did his doing that mean? The second question is, as I have said, the harder question, and the one which requires more knowledge and insight. It is evident, on the surface, that the further away we get in the child's life from simple inherited or reflex responses, the more complicated do the processes become, and the greater becomes the difficulty of a.n.a.lyzing them, and arriving at a true picture of the real mental condition which lies back of them.

To ill.u.s.trate this confusion, I may cite one of the few problems which psychologists have attempted to solve by experiments on children: the determination of the order of rise of the child's perceptions of the different colours. The first series of experiments consisted in showing the child various colours and requiring him to name them, the results being expressed in percentages of correct answers to the whole number. Now this experiment involves no less than four different questions, and the results give absolutely no clew to their separation. It involves:

1. The child's distinguis.h.i.+ng different colours displayed simultaneously before it, together with the complete development of the eyes for colour sensation. 2. The child's ability to recognise or identify a colour after having seen it once. 3. An a.s.sociation between the child's colour seeing and word hearing and speaking memories, by which the proper name for the colours is brought up in his mind. 4.

Equally ready facility in the p.r.o.nunciation of the various names of the colours which he recognises; and there is the further embarra.s.sment, that any such process which involves a.s.sociation of ideas, is as varied as the lives of children. The single fact that speech is acquired long after objects and some colours are distinguished, shows that results reached by this method have very little value as far as the problem of the first perception of colours is concerned.

That the fourth element pointed out above is a real source of confusion is shown by the fact that children recognise many words which they can not readily p.r.o.nounce. When this was realized, a second phase in the development of the problem arose. A colour was named, and then the child was required to pick out that colour. This gave results different from those reached by the first method, blue and red leading the list in correct answers by the first method, while by this second method yellow led, and blue came near the end of the list.

The further objection that colours might be distinguished before the word names are learned, or that colour words might be interchanged or confused by the child, gave rise to what we may call the third stage in the statement of the problem. The method of "recognition" took the place of the method of "naming." This consisted in showing to a child a coloured disk, without naming it, and then asking him to pick out the same colour from a number of coloured disks.

This reduces the question to the second of the four I have named above. It is the usual method of testing for colour blindness, in which, from defects of vision, certain colours can not be perceived at all. It answers very well for colour blindness; for what we really want to learn in the case of a sailor or a signal-man is whether he can recognise a given signal when it is repeated; that is, does he know green or red to be the same as his former experience of green or red? But it is evident that there is still a more fundamental question in the matter--the real question of colour perception. It is quite possible that a child might not recognise an isolated colour when he could really very well distinguish the colours lying side by side. The last question, then, is this: When does the child get the different colour _Sensations_ (not recognitions), and in what order?

To solve this question it would seem that experiments should be made upon younger children. The results described above were all secured after the children had made considerable progress in learning to speak.

To meet this requirement another method may be used which can be applied to children less than a year old. The colours are shown, and the child led to grasp after them. This method is of such a character as to yield a series of experiments whose results are in terms of the most fundamental movements of the infant; it can be easily and pleasantly conducted; and it is of wide application. The child's hand movements are nearly ideal in this respect. The hand reflects the child's first feelings, and becomes the most mobile organ of his volition, except his organs of speech. We find spontaneous arm and hand movements, reflex movements, reaching-out movements, grasping movements, imitative movements, manipulating movements, and voluntary efforts--all these, in order, reflecting the development of the mind.

To ill.u.s.trate this method, I may cite certain results reached by myself on the questions of colour and distance perception, and right-handedness in the child.

_Distance and Colour Perception._--I undertook at the beginning of my child H.'s ninth month to experiment with her with a view to arriving at the exact state of her colour perception, and also to investigate her sense of distance. The arrangements consisted in this instance in giving the infant a comfortable sitting posture, kept constant by a band pa.s.sing around her chest and fastened securely to the back of her chair. Her arms were left bare and quite free in their movements.

Pieces of paper of different colours were exposed before her, at varying distances, front, right, and left. This was regulated by a framework, consisting of a horizontal rod graded in inches, projecting from the back of the chair at a level with her shoulder and parallel with her arm when extended straight forward, and carrying on it another rod, also graded in inches, at right angles to the first. This second rod was thus a horizontal line directly in front of the child, parallel with a line connecting her shoulders, and so equally distant for both hands. This second rod was made to slide upon the first, so as to be adjusted at any desired distance from the child. On this second rod the colours, etc., were placed in succession, the object being to excite the child to reach for them. So far from being distasteful to the infant, I found that, with pleasant suggestions thrown about the experiments, the whole procedure gave her much gratification, and the affair became one of her pleasant daily occupations. After each sitting she was given a reward of some kind. I give the results, both for colour and distance, of 217 experiments. Of these 111 were with five colours and 106 with ordinary newspaper (chosen as a relatively neutral object, which would have no colour value and no a.s.sociation, to the infant).

_Colour._--The colours range themselves in the order of attractiveness--blue, red, white, green, and brown. Disregarding white, the difference between blue and red is very slight, compared with that between any other two. This confirms the results of the second method described above. Brown, to my child--as tested in this way--seemed to be about as neutral as could well be. A similar distaste for brown has been noticed by others. White, on the other hand, was more attractive than green. I am sorry that my list did not include yellow. The newspaper was, at reaching distance (9 to 10 inches) and a little more (up to 14 inches), as attractive as the average of the colours, and even as much so as the red; but this is probably due to the fact that the newspaper experiments came after a good deal of practice in reaching after colours, and a more exact a.s.sociation between the stimulus and its distance. At 15 inches and over, the newspaper was refused in 93 per cent of the cases, while blue was refused at that distance in only 75 per cent, and red in 83 per cent.

_Distance._--In regard to the question of distance, the child persistently refused to reach for anything put 16 inches or more away from her. At 15 inches she refused 91 per cent of all the cases, 90 per cent of the colour cases, and, as I have said, 93 per cent of the newspaper cases. At nearer distances we find the remarkable uniformity with which the safe-distance a.s.sociation works at this early age. At 14 inches only 14 per cent of all the cases were refused, and at 13 inches only about 7 per cent. There was a larger percentage of refusals at 11 and 12 inches than at 13 and 14 inches, a result due to the influence of the brown, which was refused consistently when more than 10 inches away. The fact that there were no refusals to reach for anything exposed within reaching distance (10 inches)--other attractive objects being kept away--shows two things; (1) the very fine estimation visually of the distance represented by the arm-length; and (2) the great uniformity at this age of the phenomenon of Motor Suggestion upon which this method of child study is based, and which is referred to again below. In respect to the first point, it will be remembered that the child does not begin to reach for anything that it sees until about the fourth or sixth week; so it is evident at what a remarkably fast rate those obscure factors of size, perspective, light and shade, etc., which signify distance to the eye, become a.s.sociated with arm movements of reaching. This method, applied with proper precautions, obviates many of the difficulties of the others. There are certain requirements of proper procedure, however, which should never be neglected by any one who experiments with young children.

In the first place, the child is peculiarly susceptible to the appeals of change, novelty, chance, or happy suggestion; and often the failure to respond to a stimulus is due to distraction or to discomfort rather than to lack of intrinsic interest. Again, fatigue is a matter of considerable importance. In respect to fatigue, I should say that the first signs of restlessness, or arbitrary loss of interest, in a series of stimulations, is sufficient warning, and all attempts at further experimenting should cease. Often the child is in a state of indisposition, of trifling nervous irritability, etc.; this should be detected beforehand, and then nothing should be undertaken. No series longer than three trials should be attempted without changing the child's position, resting its attention with a song, or a game, etc., and thus leading it fresh to its task again. Furthermore, no single stimulus, as a colour, should be twice repeated without a change to some other, since the child's eagerness or alertness is somewhat satisfied by the first effort, and a new thing is necessary to bring him out to full exercise again. After each effort or two the child should be given the object reached for to hold or play with for a moment; otherwise he grows to apprehend that the whole affair is a case of "Tantalus." In all these matters very much depends upon the knowledge and care of the experimenter, and his ability to keep the child in a normal condition of pleasurable muscular exercise throughout.

In performing colour experiments, several requirements would appear to be necessary for exact results. Should not the colours chosen be equal in purity, intensity, l.u.s.tre, illumination, etc.? In reference to these differences, I think only that degree of care need be exercised which good comparative judgment provides. Colours of about equal objective intensity, of no gloss, of relatively evident spectral purity, under constant illumination--this is all that is required. The variations due to the grosser factors I have mentioned--such as condition of attention, physical unrest, disturbing noises, sights, etc.--are of greater influence than any of these more recondite variations in the stimulus. Intensity and l.u.s.tre, however, are certainly important. It is possible, by carefully choosing a room of pretty constant daylight illumination, and setting the experiments at the same hour each day, to secure a regular degree of brightness if the colours themselves are equally bright; and l.u.s.tre may be ruled out by using coloured wools or blotting-papers. The papers used in the experiments given above were coloured blotting-papers. The omission of yellow is due to the absence, in the neighbourhood, of a satisfactory yellow paper.

The method now described may be further ill.u.s.trated by the following experiments on the use of the hands by the young child.

_The Origin of Right-handedness._--The question, "Why are we right or left-handed?" has exercised the speculative ingenuity of many men. It has come to the front anew in recent years, in view of the advances made in the general physiology of the nervous system; and certainly we are now in a better position to set the problem intelligently and to hope for its solution. Hitherto the actual conditions of the rise of "dextrality" in young children--as the general fact of uneven-handedness may be called--have not been closely observed. It was to gain light, therefore, upon the facts themselves that the experiments described in the following pages were carried out.

My child H. was placed in a comfortable sitting posture, the arms left bare and free in their movement, and allowed to reach for objects placed before her in positions exactly determined and recorded by the simple arrangement of sliding rods already described. The experiments took place at the same hour daily, for a period extending from her fourth to her tenth month. These experiments were planned with very great care and with especial view to the testing of several hypotheses which, although superficial to those who have studied physiology, yet constantly recur in publications on this subject. Among these theories certain may be mentioned with regard to which my experiments were conclusive. It has frequently been held that a child's right-handedness arises from the nurse's or mother's constant method of carrying it, the child's hand which is left free being more exercised, and so becoming stronger. This theory is ambiguous as regards both mother and child. The mother, if right-handed, would carry the child on the left arm, in order to work with the right arm. This I find an invariable tendency with myself and with nurses and mothers whom I have observed. But this would leave the child's left arm free, and so a right-handed mother would be found with a left-handed child! Again, if the mother or nurse be left-handed, the child would tend to be right-handed. Or if, as is the case in civilized countries, nurses largely replace the mothers, it would be necessary that most of the nurses be left-handed in order to make most of the children right-handed. Now, none of these deductions are true. Further, the child, as a matter of fact, holds on with both hands, however it is itself held.

Another theory maintains that the development of right-handedness is due to differences in weight of the two lateral halves of the body; this tends to bring more strain on one side than the other, and to give more exercise, and so more development, to that side. This evidently a.s.sumes that children are not right or left-handed before they learn to stand. This my results given below show to be false.

Again, we are told that infants get right-handed by being placed on one side too much for sleep; this can be shown to have little force also when the precaution is taken to place the child alternately on its right and left sides for its sleeping periods.

In the case of the child H., certain precautions were carefully enforced. She was never carried about in arms at all, never walked with when crying or sleepless; she was frequently turned over in her sleep; she was not allowed to balance herself on her feet until a later period than that covered by the experiments. Thus the conditions of the rise of the right-handed era were made as simple and uniform as possible.

The experiments included, besides reaching for colours, a great many of reaching for other objects, at longer and shorter distances, and in unsymmetrical directions. I give some details of the results of the experiments in which simple objects were used, extending over a period of four months, from the fifth to the ninth in her life. The number of experiments at each sitting varied from ten to forty, the position of the child being reversed as to light from windows, position of observation, etc., after half of each series.

No trace of preference for either hand was discernible during this period; indeed, the neutrality was as complete as if it had been arranged beforehand, or had followed the throwing of dice.

I then conceived the idea that possibly a severer distance test might affect the result and show a marked preferential response by one hand over the other. I accordingly continued to use a neutral stimulus, but placed it from twelve to fifteen inches away from the child. This resulted in very hard straining on her part, with all the signs of physical effort (explosive breathing sounds resulting from the setting of the larynx, rush of blood to the head, seen in the flus.h.i.+ng of the face, etc.). The number of experiments in each series was intentionally made very small, from one to twelve, in order to avoid fatigue.
