Some fruits are good sources of many nutrients
As with vegetables, some fruits are good sources of many nutrients, including carbohydrates and fiber. In addition, fruits, unlike most desserts, can satisfy your sweet tooth without tipping the scales. Also unlike many desserts, fruits provide our bodies with a variety of important vitamins and minerals.
Choices include:
apple, fresh juice sauce
apricots, * fresh canned in juice dried
banana
berries, ** except strawberries strawberries
cherries
dates
figs, fresh and dried
fruit cocktail, fresh or canned grapefruit, ** fresh canned in juice juice
grapes
kiwi**
kumquats
mango
melon, *** except watermelon watermelon
nectarine***
orange, ** fresh Mandarin sections juice
papaya
peach, * fresh canned in juice
pear, fresh canned in juice
persimmon
pineapple, fresh canned in juice juice
plums
prunes
prune juice
raisins
tangerine**
* Good source of vitamin A
** Good source of vitamin C

Vegetables are vital to heart health
As excellent sources of vitamins, minerals, complex carbohydrates and fiber, vegetables are vital to heart health. To get the most nutrition from vegetables, eat them raw or minimally cooked (steamed). Keep in mind that each vegetable provides different vitamins and minerals, making variety important. As a role, if the outer portion of the vegetable is edible, that's where you'll find the majority of vitamins and minerals.
One unit in the vegetable group equals 1/2 cup cooked or 1 medium raw vegetable. Choices include:
artichoke
asparagus**
bamboo shoots
beets
broccoli***
Brussels sprouts
cabbage**
carrot*
cauliflower
celery
cucumber
eggplant
greens***(collard, endive, escarole, lettuce, spinach)
kohlrabi
leeks
mushrooms
okra
onion
parsnip
peas
peppers***
pumpkin*
radish
rutabaga
scallions
shallots
squash*
snow peas
string beans
sweet potatoes*
tomato**
tomato juice or tomato-juice cocktail, low-sodium turnips**
water chestnuts
yams*
zucchini
*Good source of vitamin A
** Good source of vitamin C

Note: Starchy vegetables higher in complex carbohydrates are found in the grains group. Tomato juice and tomato-juice cocktail are high in sodium. Select the low-salt variety or make your own!
Learning to Relax
Lie down in a quiet, darkened room. Hold your neck muscles slightly stiff, moderately stiff, quite stiff, then as stiff as you can make them. Now move backwards along the same scale, from totally stiff to quite stiff, to moderately stiff, to slightly stiff, to normal - and then one more step in the same direction, towards looseness and relaxation beyond the original base level. Go through this routine three or four times, until you definitely 'get the feel of it' and can relax your neck muscles at will.
Now you are ready to relax other parts of your body.
Relax your right arm, your right leg, your left leg, your left arm, your scalp, your face, your neck, your back and your tummy muscles. This order - around the clock, then top to bottom - is easy to remember. Do not strive for maximum relaxation of each part: you will relax more thoroughly in a given length of time by focusing your attention on each part only long enough to loosen its musculature through a single 'relaxation command', then shifting your attention to the next body part. After three or four 'go-rounds' you will find yourself drifting into a state of highly restful calm which you can easily maintain for some time.
When you first try part-by-part relaxation, twenty-minute rest breaks in a quiet bedroom work best. After a few weeks, however, you will become good enough at relaxing muscle groups that isolation and quiet are no longer necessary. You can sit in a straight chair with both feet flat on the floor, place your hands in your lap, let your head loll forward, and relax muscle groups in rotation just as if you were in bed. Even when children are playing in the vicinity or dinner is cooking on a nearby stove, you will find that you can readily relax. After two or three 'go-rounds', lift one hand up to shoulder height and let it fall back into your lap like a limp dishrag. Do the same with the other hand. Then resume part-by-part relaxation, perhaps for two to three minutes. Such brief 'refresher slouches' will definitely help to keep tension from building up, of ten with startling effects on your disposition, level of contentment, and sexual responsiveness.
A few more weeks of practice will improve your ability to relax to the point where a set position and chair- or bed supported posture are no longer entirely necessary. Whenever you become conscious of muscular tension you will be able to relax it without interrupting your activities.
Reducing your risk for developing coronary heart disease
1. Consult your physician.
2. Monitor your eating and activity behaviors.
3. Familiarize yourself with foods that contain small or large amounts of cholesterol, fats and sodium.
4. Follow the suggested food-group units for a diet of 1600 or 2000 calories, or calculate your own individual energy needs. The less active you are, the fewer calories you can afford to eat without gaining weight.
5. Study the sample menus that follow to assist you in designing your own diet. What is important is that you generally eat as suggested, paying more attention to the types of food you eat and the way the foods are prepared than to exact amounts. Of course, this does not mean you should eat more than suggested if you are trying to lose weight or if you find you are gaining undesired weight. Use your common sense in these matters.

Rebelliousness, Morality, and Psychological Health
A second consideration which is certainly no news to most people, but which tends to get lost to psychologists who use phrases like guilt feelings, hostility, and anxiety, is that the healthy person psychologically is usually virtuous in the simple moral sense of the term. Psychologically healthy people do what they think is right, and what they think is right is that people should not lie to one another or to themselves, that they should not steal, slander, persecute, intrude, do damage willfully, go back on their word, fail a friend, or do any of the things that put them on the side of death as against life. This probably sounds like old-time religion, and in fact I am willing to be straightforwardly theological about this. I think there is an objective character to guilt, and when a person is false to his nature or offends against the nature of others then he is in sin and the place in which he has his existence is well described by the word "hell." I take "sin" here to be descriptive of the state of separation from the most basic sense of selfhood, or what some existentialist philosophers have called "the grounds of being." In whatever terms it is put, the fact is that a person is most alive and is functioning in such a way that he knows who he is and you know who he is and he knows who you are when his thoughts and actions are in accord with his moral judgment. The corollary is that when you do what you think is wrong you get a feeling of being dead, and if you are steeped in such wrongful ways you feel very dead all the time, and other people know that you are dead. There is such a thing as the death of the spirit. Many of the people whom we know as patients in our mental hospitals or as prisoners in our jails are in a condition of spiritual death, and their only hope is that someone can reach out to them, break through the walls of their isolation, recognize them. I think that too much has been made of the word love in this connection, for usually it connotes a feeling on the part of the person who is to give the love. The essence of the act of love as I understand it is the act of attention, and the affect that accompanies it in the person who is paying attention may be love, hate, sadness, or what have you. A real fight is an act of attention, a genuine condemnation is an act of attention, an understanding of final defeat is an act of attention. These as well as their positive counterparts are on the side of life, and the person who experiences them is in communication with other living beings and offers to them the possibility of community. The sort of philosophy of psychotherapy that prescribes blandness, nonjudgmentalness, and essential indifference on the part of the psychotherapist is simply a form of human debasement. Paying attention, caring, and being there yourself is all that counts.
One of the therapists there was clearly an incompetent by all standarts. Everything he did was wrong. After about six months of his residency, however, it became apparent that many of his patients were unaccountably getting better. Among his aberrant behaviors were such gross actions as telephoning a patient's foreman at work and telling him to stop bullying the patient, suggesting an unusual sexual technique to another patient whose wife was apparently frigid, and bluntly suggesting to a third patient that he should give up his job as an automobile repairman and get into the dispensing of food. The climax of the latter case was especially gruesome to the clinic, for the patient opened a doughnut shop of his own and on his final appointmerit appeared with a dozen doughnuts of his own making which he presented as a gift to the therapist, who without any insight at all offered them around to various other therapists and his supervisor of whom had difficulty, swallowing them. Goodness knows I am not suggesting, in recalling the case of this incompetent fellow, that all psychotherapists go forth and do likewise, for he was he and we are we. But I will say that he was alive, even though so obviously misguided; to his patients, the only thing that was of consequence was that he cared about them and that he thought there was something different they could do which would be right.
Parent Education and Mental Hygiene
There is a tendency in some quarters to view with suspicion the efforts of groups of parents to learn something about mental hygiene as applied to themselves and to their children. Probably not a large number of parents are as yet actually helped; possibly, too, a certain number are harmed--the psychiatrists report a few parents getting just enough of the jargon and the general point of view to find "problem" children where these do not exist. On the whole, however, it is doubtful whether in any other educational field (except the nursery school) mental health principles have penetrated as far and as well as in the modern plans and practices in parent education and education for family life.
Formerly programs for study [by parents' groups] focused attention exclusively upon the child and included for discussion such topics as obedience, punishment, rewards, curiosity, imagination, habit formation, play, etc. More recently, especially with leaders trained in mental hygiene, interest focuses upon the life of the family groups and upon such items as personality development in family relationships, emotional honesty in dealing with children, etc. In attending such study groups parents are able to learn not only important facts about child growth and the family in a changing world, but also more satisfactory self-direction in their daily relationships with children.
So definitely has mental hygiene entered into modern education for family relations that in nearly all the current definitions mental health as an objective is either explicitly stated or unmistakably implied.
Parent education is a voluntary cooperative effort by parents, studying with qualified leaders (1) to understand more about childgrowth and development, family relationships, the conduct of family life, public education, home-school relationships, and the family in community life; and (2) to grow in ability to take a constructive part in family and community relationships with confidence and satisfaction.
Classification of objectives of parent education reflects clearly, especially in the first three of her list, the recent mental health emphasis in education for family relations:
1. To interpret to parents the findings of specialists in regard to various aspects of child and family life.
2. To modify or change the attitudes of parents toward their children and their behavior.
3. To act as a therapeutic device for relieving personal maladjustment.
With the increased knowledge available about human nature and the ways in which it develops and is modified, education in family relations ceases to be the simple matter it was in the past and is sometimes assumed to be today. Many parents who pride themselves on following to the letter the prescribed rules for the physical hygiene of their children. Even among those who realize the importance of early control of behavior problems, there are many who are deeply concerned when their children lie, steal, or have temper tantrums but attach little or no significance to such unhealthy signs as undue self-consciousness, day-dreaming or jealousy. Still less do they realize that these delinquencies and manifestations of abnormal behavior may be due to their own attitude toward their children. Yet many cases of delinquency in children have been traced to the attempt of parents to make the child's life compensate for their own failure to reach certain goals of achievement; to the fact that the child has for years been buffeted between the rigid discipline of one parent and the extreme laxity of the other; to the dominating attitude of one member of the family group, which leaves the child no opportunity for asserting himself as an individual, and to similar forms of conflict between the needs of the child and the conditions prevailing in his family. Parental attitudes are of fundamental importance.
Personality begins very early and persists very late
Possibilities for the school, therefore, are definitely limited at the start. The "education" of the child has been under way for a number of years before he comes to school. What education can do for mental health will depend to a considerable extent on what the family and home have already done; also on what the family continues to do while the youngster is in school. Where the public educational provision includes the nursery school, as it should, the school is able to exert its influence at an earlier stage, of course, but the part of the home remains highly significant even then.
Most authorities believe that the influence of the home and family in making or breaking wholesome personality begins very early and persists very late. Babies in the first year, who showed all the marked differences that characterize later personalities--some slow in their reactions, phlegmatic, dull; others quick, amiable, responding with distinct pleasure to the different stimuli, or with clear evidence of discomfort. At the other end of the scale, there have been some noteworthy cases of adjustment of very difficult boys and girls in foster home surroundings long after older adolescence and beyond.
Clinical case records indicate that the home is still the major force in forming the personality of children. On the ground that home life, quite apart from its physical aspects, may react upon the health of the child by its confusion and discord, or by its harmony and peace, and "this in turn is largely the result of the parents' own emotional adjustment.
It is in the home that the child's needs for affection, security, and opportunities for growth or development, which play so important a part in shaping his personality, are met or thwarted. Even the most affectionate and intelligent parents may not always fully understand the child's needs for security and growth. Security is founded upon the emotional maturity of parents, upon justice, truthfulness, regularity, order and serenity in the home. Opportunities for development can be given the child only by parents who want to see him grow and give him every chance to utilize and enlarge his own powers.

Fully Functioning Persons - Educational Achievement
Even with this limited definition of the goals of education, the abilities involved in creative thinking cannot be ignored. There has been increasing recognition of the fact that traditional measures of intelligence attempt to assess only a few of man's thinking abilities. Certainly we cannot say that one is fully functioning mentally, if the abilities involved in creative thinking remain undeveloped or are paralyzed. These are the abilities involved in becoming aware of problems, thinking up possible solutions, and testing them. If their functioning is impaired, one's capacity for coping with life's problems is indeed marginal.
Educational Achievement
Almost no one disputes the legitimacy of the school's concern about educational achievement. Teachers and guidance workers are asked to help under-achievers to make better use of their intellectual resources and to help over-achievers become better "rounded" personalities. But, how do you tell who is an under- or over-achiever? In my opinion, recent findings concerning the role of the creative thinking abilities in educational achievement call for a revision of these long-used concepts.
We are finding that the creative thinking abilities contribute importantly to the acquisition of information and various educational skills. Of course, we have long known that it is natural for man to learn creatively, but we have always thought that it was more economical to teach by authority. Recent experiments have shown that apparently many things can be learned creatively more economically than they can by authority, and that some people strongly prefer to learn creatively.
Traditional tests of intelligence are heavily loaded with tasks requiring cognition, memory, and convergent thinking. Such tests have worked rather well in predicting school achievement. When children are taught by authority these are the abilities required. Recent and ongoing studies, however, show that even traditional subject matter and educational skills can be taught in such a way that the creative thinking abilities are important for their acquisition.
Most of these findings are illustrated dramatically in a study conducted during three years in the University of Minnesota Laboratory Elementary School. We differentiated the highly creative children (as identified by our tests of creative thinking) from the highly intelligent. The highly creative group ranked in the upper 20 per cent on creative thinking but not on intelligence. The highly intelligent group ranked in the upper 20 per cent on intelligence but not on creativity. Those who were in the upper 20 per cent on both measures were eliminated, but the overlap was small. In fact, if we were to identify children as gifted on the basis of intelligence tests, we would eliminate from consideration approximately 70 per cent of the most creative. This percentage seems to hold fairly well, no matter what measure of intelligence we use and no matter what educational level we study, from kindergarten through graduate school.
Although there is an average difference of over 25 IQ points between these two groups, there are no statistically significant differences in any of the achievement measures used either year.
It is of special interest that the children with high IQ's were rated by their teachers as more desirable, better known or understood, more ambitious, and more hardworking or studious. In other words, the highly creative child appears to learn as much as the highly intelligent one, at least in some schools, without appearing to work as hard. My guess is that these highly creative children are learning and thinking when they appear to be "playing around." Their tendency is to learn creatively more effectively than by authority. They may engage in manipulative and/or exploratory activities, many of which are discouraged or even forbidden. They enjoy learning and thinking, and this looks like play rather than work.
Mental Health - what does all this have to do with creativity
Schools are legitimately concerned about the mental health of children, adolescents, college students, and adults. They would like to be able to help their students avoid mental breakdowns and achieve healthy personality growth. These are legitimate concerns of education. But what does all this have to do with creativity?
Actually, it has a great deal to do with creativity. There is little question but that the stifling of creativity cuts at the very roots of satisfaction in living and ultimately creates overwhelming tension and breakdown. There is also little doubt that one's creativity is his most valuable resource in coping with life's daily stresses.
In one study, a battery of tests of creative thinking was administered to a group of schizophrenics who appeared to be on the road to recovery. Many of them were being considered for vocational rehabilitation by the State Department of Welfare. These individuals manifested an astonishingly impoverished imagination, inflexibility, lack of originality, and inability to summon any kind of response to new problems. Their answers gave no evidence of the rich fantasy and wild imagination popularly attributed to schizophrenics. There was only an impoverished, stifled, frozen creativity. They appeared to be paralyzed in their thinking, and most of their responses were the most banal imaginable.
Although it will be difficult to prove, I suspect that schizophrenics and others who "breakdown" under stress constitute one of the most unimaginative, noncreative groups to be found. I also suspect that it was their lack of creativity rather than its presence which brought about their breakdowns. Certainly the schizophrenics tested lacked this important resource for coping with life's stresses. Creativity is a necessary resource for their struggle back to mental health.

History of Biochemistry and Its Medical Applications
In contrast with the cosmic earthquake that the study of physics underwent in the years before 1930, change moved tranquilly in the fields of biology and chemistry. Indeed in biology most of the work of the 1920's continued along lines already established in the nineteenth century.
In genetics, the key event was the rediscovery in 1900 of the work of the Bohemian monk Gregor Mendel, who, contemporaneously with the later researches of Darwin in the 1860's, conducted the epoch-making experiments with the crossbreeding of peas that were to form the basis of the whole modern study of inheritance. The most significant outcome of Mendel's discoveries was the identification of indivisible and unalterable units called genes, through whose infinitely varied combination the process of heredity proceeded. This genetic theory seriously undermined Darwin's principle of natural selection. Some geneticists were ready to discard natural selection entirely, some preferred to retain it in modified form, but there was general agreement that acquired characteristics were not inherited. Mendel's original conclusions were reinforced when twentieth-century geneticists began to extend his work to systematic experiments with the fast-reproducing fruit fly, and to apply the calculus of probabilities to their findings. As a result, by the 1920's the new science of genetics had reached a high level of technical exactitude. Moreover, in treating the gene as a basic and indivisible unit, it seemed to confirm Planck's contention that nature proceeded by jumps and in definite quantities rather than through the continuous and imperceptible processes of change that had been postulated by nineteenth-century philosophers of nature.
Another link between biology and the theory of physics was provided by the new science of biophysics, which, along with the related field of biochemistry, accounted for a large part of the progress made in the study of the human body. Perhaps the most dramatic experiments were those of Sir Frederick Gowland Hopkins in 1912, which became the starting point for the systematic investigation of nutrition and the identification of the basic vitamins. For a long time the chemistry of all the vitamins except D remained a mystery. But in 1929, with the chemical breakdown of Vitamin A, there began a period of rapid progress in the analysis and synthetic production of these substances that continued down to the outbreak of the Second World War.
Closely related to this study was the development of the new science of glands and internal secretions known as endocrinology. In the 1920's, the function of hormones began to be understood, and work on the pituitary and thyroid glands proceeded steadily. Discoveries such as these obviously had relevance for medicine. Indeed, a salient characteristic of the decade was that now, for the first time in history, new research in physiology and biochemistry was quickly applied in clinical practice. An astounding advance resulted. In the mid-1920's there began a period of breathtaking innovation that brought more progress in medicine in a single generation than the profession had known in all previous human history.
The discovery of antitoxins, begun in the 1890's, moved on steadily, as did the analysis of the corresponding viruses. By this method, medical research succeeded in eliminating certain diseases almost completely: as smallpox had been routed in the nineteenth century, so the conquest of diphtheria, yellow fever, and tetanus followed in the interwar period. But most diseases resisted this sort of immunization. Although the ravages of tuberculosis, for instance, were enormously reduced, no satisfactory antitoxin was discovered to combat it. In dealing with these stubborn diseases, the development of antibiotics marked the crucial turning point. Beginning with Sir Alexander Fleming's almost accidental discovery of penicillin in 1928, one new drug followed another in a rapid sequence of successful experiments leading to commercial production.
In all these cases, however, there had been a time lag between laboratory research and its clinical application. Not until the Great Depression had focused attention on problems of hunger and want were the new discoveries in the field of nutrition and vitamins fully exploited. Through the necessities of treating vast masses of sick and wounded soldiers in the Second World War, penicillin, the sulfa drugs, and DDT came into their own. These examples suggest the close relationship between social needs and the development of scientific and medical knowledge in our time.
Similarly, in the organization of research, economic and social factors began to exert an increasingly important influence. In the past, the isolated scientist or physician could produce useful and even epoch-making results with the simple equipment of his own home laboratory. By the 1920's, only a wellfurnished laboratory or research institute could contribute to the growth of scientific knowledge. With this change, the problem of the organization and financing of research took on a new urgency. In such respects, a large and wealthy society like that of the United States enjoyed obvious advantages; a socialized country, such as the Soviet Union, held potential assets for the future. Thus even as early as the 1920's, men of science in the three countries that together had accounted for most of the scientific progress of the nineteenth century--Britain, Germany, and France--were beginning to wonder whether the economy and the way of life that had yielded such marvelous results a generation or two earlier, would prove capable of dealing with the unfamiliar and pressing demands of twentieth-century mass society.

School Companions and Friendships
Factors in the Formation of Groups
During the first four or five years of the child's life the factors that induce the child's contacts with others and the formation of groups seem to be helplessness and need, companionship in play, and common interests in toys or other objects. These earliest groups usually have two members, while later on larger groups are formed. During the years from six to twelve, common interests and activities, similarity in chronological, mental, and developmental ages, are factors underlying the formation of groups. Such groups are more stable and lasting than the rapidly shifting groupings of the pre-school years. Various environmental factors also may be influential, such as living in a certain neighborhood close to some other groups whose activities are well known. At about the eighth to tenth years boys and girls frequently form clubs or gangs of one sort or another. Many of these are short-lived. A name, membership dues, a time and place of meeting, a list of members, and no very definite specified purposes, are common characteristics of many clubs at this age. We have studied many of them among public-school children, ages eight to fourteen. Girls' clubs are common at these ages and are very transitory and short-lived. Boys' clubs seem to be more definite in their objectives and more lasting. It may be that boys feel a keener need for such social groupings. The intimacy, loyalty, and solidarity in some of these groups are truly remarkable, as various detailed accounts of them have shown.
Community feeling, however, seems to be slow in developing. Tattling is found in the earlier school years. Identification of one's self with the group in such a vital way as to regard group success as highly satisfying is also slow in developing. Doing things for the good of the group, as in teamwork, develops gradually. Even several years after the child begins school it may have little motivating power in child behavior. Anyone organizing a baseball team of ten-year-old boys is not likely to have any scarcity of candidates for catching, pitching, first base, and short stop, but he will lack fielders.
Social Concepts of Children Six to Twelve Years of Age
Such concepts as playing fairly, being kind, helping others, and the like have their beginnings in the early pre-school years. Normally they are well developed before the advent of puberty. We must not conclude, however, that having an accurate knowledge of certain social concepts insures their operation in the daily lives of children. Often a notable discrepancy is found between knowledge and overt behavior.
Social Contacts and Adjustment of Later Childhood
Entrance upon school, provides stimuli to many social reactions. The first reactions of children to school are not necessarily complete indications of their social development. Thus, a one-year study of forty seven-year-old boys just entering school showed that thirteen were confident, sixteen indifferent, and eleven were shy. The early over-submissiveness to the teacher's authority tended to disappear during the first six weeks. Considerable disobedience was found, even though the authority of the teacher was clearly recognized and not disputed. Often difficulties arose because the boys did not know exactly what was expected of them, or because they misunderstood the meaning of a given command.
Various schemes for classifying children's social contacts have been devised. One type of classification divides social contacts into, five principal classes. (1) Protective contacts are those in which the shy and submissive or uncertain child attaches himself to the selfassertive. If anything happens to break up the association, the timid child seeks someone else to whom he may attach himself. (2) Social contacts may reveal a certain kind of devotion in which a beloved or popular child is the center of a group, not because of any marked leadership, but because of his gentle, friendly, attractive ways which make so many children like him. (3) Social contacts also may be those of the "leader." (4) Sometimes they show the "despot." (5) A fifth type is that of the child who is socially unsuccessful. Social contacts, characterized as a despotism, tend to diminish by the time children finish kindergarten or enter first grade. Force as a controlling element becomes socially unacceptable and many children give it up. The socially unsuccessful child often is the one who has some physical defect or who has been badly neglected, having torn, dirty, or ill-fitting clothing. Often such children become trouble-makers in school. By the beginning of the school years the range of the child's social reactions is vast indeed. By the age of twelve years, nearly every type of social response has appeared, although the range and complexity of the situations evoking them are far from the scope shown in later adolescence or adulthood.
The Relationship of Language to Social Development
Social Attitudes of Pre-School Children
Socially indifferent children are rare, however, at the age of four or five years. A few may be observed who seem almost lacking in social perception, and whose behavior is very little influenced by the activities of others. Mental ability has some effect on this characteristic. We have seen feebleminded children ten to twelve years of age who seemed to give no sign of being aware of the presence or activity of other persons. At the very bottom of the scale of intelligence there are always children whose social behavior is practically zero.
Social dependence or social independence may be quite marked in pre-school children, although most youngsters possess this trait in some degree intermediate between the extremes. The social dependence or independence of a child is probably the result of his training, and experience more than of any other factors. We have observed many children in kindergartens of city public schools and in free kindergartens maintained by charitable and philanthropic organizations and have seen timid children lose much of their timidity in groups and develop leadership in group activities. The child on whom satisfactions are bestowed because of his submissiveness, who is threatened into frequent yielding, or who is given no opportunities for spontaneous and voluntary action, is likely to be dependent. When these circumstances operate in the opposite manner, independence results. Since most children receive these stimulations in an intermediate degree, they are neither strikingly dependent nor independent, or else they show these characteristics differently in various particular situations.
The Formation of Friendships During the First Five Years
Obviously, the factors which further the formation of friendships in childhood are those which satisfy, please, comfort, or help the child in some way. Factors which hinder or prevent the formation of friendships are those which irritate, anger, pain, or otherwise displease the child. A very long list of specific conditions tending to develop friendliness could be given, and another list conducive to unfriendliness could be set forth. The close contacts incident to living in the same family may lead to bitter hatred or warm affection. If children interfere with each other in any way continually for a considerable period of time, they are likely to become unfriendly and jealous of each other. With young children proximity is a very common factor in friendship and companionship. The child cannot go far from home. Accordingly, he makes friends with children near at hand. Mere propinquity may not be enough to develop companionship, but if the children are near the same age, they are likely to have enough community of interest to become friends. At all ages, it would seem, community of interest is a very important factor conditioning friendship. Children who like to do the same things are likely to be friends, if they have the opportunity to be together so as to discuss their common likes, provided, of course, that other conditions giving rise to friction are absent.
When pre-school children are allowed to form groups freely, sex plays less of a part than with older children who tend to group themselves according to sex. Children, if left to themselves, form groups largely upon the basis of acceptable behavior and ability to enter into the group activities. When race, color, poverty, or riches are factors in the formation of groups of pre-school children, we may be sure that home pressure or the influence of other adults is likely to be responsible for the social discrimination displayed. Such factors otherwise have little meaning or value for the child of four or five years.
A youngster of three or four years of age often forms a strong attachment for some other child and seeks to be with him as much as possible. Such little chums may be seen going home together from nursery school or kindergarten. They are much together at school and out of school, if opportunity can be found. Such friendships may last for several months, although more commonly they last only a few days or weeks. We have observed many of these among kindergarten children four or five years old. Usually two children are chums. Less frequently three may be chums for a while. In one case we observed three boys who became great chums in kindergarten at the age of five. Their friendship continued through the first and second grades, until one of the boys moved to another city. We also have seen a few cases of three girls being chums in kindergarten for a short time. We have seen the close friendship between two boys or two girls lasting for some time in several cases through kindergarten and several years thereafter. We would expect such cases to be found, because some of the children, having the traits which make for friendship, are likely to develop in ways which will continue their being chums. On the whole, however, pre-school children do not maintain such chumships for a long period of time, as nurseryschool and kindergarten teachers often have observed.
Interpretation of Facial Expressions
More than 70 per cent of the kindergarten children recognized laughter, whereas less than 50 per cent of them recognized fear, anger, or pain. By the age of seven years more than half recognized anger, by eleven, more than half recognized surprise. The course of development may be seen also in the fact that the average number of photographs correctly named was 1.5 at the age of three years, and, nearly four and one-half at the age of eleven. Of course, this test is somewhat artificial because actual facial expressions are mobile or changing rather than fixed or static. Accordingly, we must not conclude that children cannot recognize fear, anger, and pain in a familiar person's behavior until the ages shown in the foregoing study. The addition of vocal expressions is a distinct supplementary aid to the child in identifying the emotional states of a familiar person.
Laughter and Crying of the Pre-School Child
The laughter and crying of children under five years of age have significance in studying their social development. Apparently, 8 more of the two-year-old's laughter takes place when he is unaware of another child's presence and is playing by himself. At a later age, however, the most laughter seems to occur when children are in social contact with other children. Boys seem to laugh most and cry most when with boys. In the latter case, the teasing or amusing nature of the social contact may be a contributing factor.

If they noticed them, it was with no interest or emotion. Even the others' movements were of no interest. Such infants played, moved about, cooed, and smiled without any interest or regard for the presence of other infants who were near. Such behavior may be regarded as exhibiting social blindness. The infants who were not socially "blind," that is, those who paid attention to the behavior of others, exhibited varying degrees of independence in social relations. At one extreme some showed a high degree of social dependence. They were much influenced by the presence and activities of other infants. At the other extreme were infants who, equally aware of the presence and activities of others, still showed a great deal of social independence. The socially dependent infant's behavior seemed to be conditioned largely by that of another. He usually copied it or he may merely have watched it. Or if he was not so timid or if his responses were not so readily inhibited, he might go through his little repertory of stunts trying to arouse or please the other. The socially independent infant was aware of the presence of the other and responded to him and his behavior, but did not seem to be dependent upon him. He played with him but was clearly the leader, not being afraid of or intimidated by the other. Children from six months to eighteen months of age possess these characteristics in greater or less degree. Bühler believed that they show them without reference to previous contacts with others, to their being only children, to the home conditions, or to nationality. We may have here early evidence of dominance and submission.
Any reference to infants as socially dependent or socially independent, however, must not be applied too rigidly. We must not think of all children who are not "socially blind" as belonging at either of these other two extremes. Some do belong to the first class and some to the second. Many, however, seem to fall into groupings between the extremes, especially as they pass from infancy to the pre-school and school years. As characterizations of general social attitudes of individuals, Bühler's classes are suggestive and valuable because they throw into clear relief important considerations in the social development of the child. No scheme of classifying children into two or three "types" is satisfactory, however, as is seen in connection with the discussion of child personalities.

Other Social Responses During Infancy
How Infants Respond to the Presence of Other Infants
Babies at four and five months of age frequently seem to be unaware of each other's presence, even though near each other. By the age of six months, however, they actively look around and attract each other's attention. Thus, the infant of six or seven months may touch another one who is near, or he may coo, or hinder the other's activities in some way. We have observed a few babies of five to eight months, placing them two at a time near each other on a bed or couch. The older ones showed distinct evidence of being aware of the presence of each other. Thus, an eight-months-old infant when placed near one of five months reached out and stroked the younger one and then took hold of her arm, cooing, gurgling, and smiling. The younger infant had given no previous sign of seeing the other and was cooing contentedly. Upon being touched, she stopped cooing, turned her head, and looked at the other baby. She did not, however, put out her hand and try to touch the older one. Responses to the presence and activities of adults and older children are observable at an earlier age than are responses to other infants of about the same age, undoubtedly because the former provide more adequate stimuli.
Earliest Social Stimulations and Responses
By the second month, social responses to persons are more clearly distinguishable. At the age of two full months, many infants will turn the head and eyes toward the sound of a human voice. These responses, of course, do not develop because of any inner social tendency, but are evidences of learned behavior.
The Recognition of Facial and Vocal Expressions
During the first two months of postnatal life the infant's smile at the presence of another human being is not dependent upon the latter's facial expression or tone of voice. The young human is not yet able to differentiate such relatively simple things as smiling and angry facial expressions, or kind and scolding words and tone. If a person bends over the crib of a two-monthsold infant and has a "smiling countenance," the infant may smile in return. But if the adult has an angry expression, the infant also may smile. The, infant even at the age of three or four months probably is unable to differentiate kind and angry looks, tones or gestures, although exceptions occur. From the close of the fourth month, however, infants show distinct signs of differentiating expressions and by the fifth month may cry at the scolding voice and threatening gesture. The child by this time has developed his powers of attention and observation to such an extent that he can watch the face and note any changes in its details. He also is capable of discriminating differences in tone of voice. Perhaps even more important is the fact that he has now learned that kindly expressions typically accompany satisfying ministrations to his needs, while harsh ones imply neglect or even painful punishment. Before the end of the first year he has made a great deal of progress in understanding vocal and facial expressions.
The Learning of Social Behavior
Although the infant is non-social at birth, he cannot remain so for a very long time. He lives in a society and is constantly dependent upon other people for his welfare and comforts. Accordingly, the infant soon learns to make responses to other persons. As he grows from infancy to childhood, these social adjustments become even more evident.
The Learning of Social Behavior
The earliest social behavior of infants arises from the care and handling given to them by, adults. When a baby is fed, dried, kept warm or petted, he responds by behavior that may be taken to indicate satisfaction. If he is restless or crying, this agitated behavior ceases. With a little greater maturity, positive evidences of pleasure are apparent in the forms of smiling, gurgling, cooing, laughing, and reaching with the arms. Fundamentally, all social behavior is based on these responses to the satisfaction of the infant's bodily needs.
During the early months of life, learning takes place by which these reactions come to be made to persons, rather than only to the actual bodily stimulations. This learning is an example of the operation of the conditioned reaction. Since the mother or nurse or some other adult is always present when these ameliorative satisfactions are administered, the sight, sound, or other symbol of these persons becomes capable of evoking the response. The beginning of social behavior in infants is dependent upon the development of their abilities of perception and discrimination and upon the occurrence of experiences through which they may learn.
Children's Recreational and Social Interests
Children at this age may play in small groups, but often they really are not playing in groups, they are merely near each other while playing. The directed play activities of the kindergarten often involve ring games, rhythmic movement, and singing games. The five-year-old is likely to enjoy construction work. If he is given some direction and if tools are available, he will try to make crude objects, using saw and hammer. Play interests at this age are characterized by the child's engaging in the activity from sheer enjoyment of it, and not to acquire any skill. With further increases of age, the nature of his play interests again changes. By the age of ten or eleven marked differences are seen. The free individual play activities without rules and competition have been displaced by games with rules and with some object or goal. Such games are likely to be largely competitive, with much rivalry in the case of boys. Interest centers on skill and excellence. The games run a definite course, that is, they have a beginning and come to an end. Little cooperation is found. In fact the adult who gets together a group of ten-year-old boys for a baseball or football team is likely to have a surplus of would-be pitchers, firstbasemen, quarterbacks, and centers, but a dearth of fielders and players who do not carry the ball. Emphasis upon speed, strength, and accuracy is characteristic of the play activities of the boy at ten. He is much interested in excelling the others in running, throwing, and the like. Using tools to make things, engaging in bicycle-riding, climbing trees, skating, swimming, camping out, and playing with various kinds of mechanical devices are also much enjoyed. Among girls of ten years, doll play has begun to decline and in the next three years will almost disappear. Playing with paper dolls, making clothes for dolls, participating in various kinds of table games, bicycle-riding, playing on the horizontal bar, house-keeping activities, puzzles, dancing, and dramatic games are common among girls of ten or eleven years.
A conspicuous change in recreational activities is suggested by the percentages of children, at each age up to fifteen, attending the movies, climbing trees, porches, and fences, riding bicycles, and playing marbles. At twelve years of age, two-thirds of the town boys and three-fifths of the town girls attend motion pictures. Nearly half of the eight- and nine-year-old town children also attend. These proportions are in distinct contrast with the smaller percentages who engage in climbing, play marbles, skip rope, etc.
The environment facilitates participation in some play activities and limits it in others, as we would expect. In all of these play problems is found the customary wide range of individual differences. Many play activities indicate the development of social interests. Girls' interests include social dancing, picnics, parties, and "dates," while boys' interests are in football, baseball, and basketball, all of which involve cooperation or teamwork.
Relation of Interest to Aptitude and Maturity
Changes in interests are partly dependent upon maturation, as may be seen in the case of children's play interests. The ten-year-old's play activities are different from those of the four-year-old, not necessarily because he has had so much experience with them that he is surfeited by them, but rather because they were suited to a degree of development which he has long since passed. The reading interests of children also vary with age because of differences in, maturity, in intelligence, in outlook, and in experience. Undoubtedly, maturation is a factor in moulding children's interests along many other lines.
Importance of Interests During Childhood
As the years of childhood pass and the child comes into adolescence, we normally find some interests more permanent and of greater strength. Efficiency is dependent upon a few intense abiding interests which lead to centering attention and effort along some particular lines. Greatest achievement seems to be dependent upon the individual's having a strong abiding interest in the work he is doing. We need not, however, expect the child to have such a narrowed, intense, and relatively permanent interest along some line. He may show a very intense interest in some one thing for a short time and then turn with equal intensity to something else, or he may show much interest in several things simultaneously. During childhood cultivating and developing a wealth of wholesome interests should be an objective of child guidance and control by both parent and teacher.
What extent do interests motivate the child's behavior?
The Meaning of Interest. Interest has two diverse meanings in psychological usage. It means a condition or cause of attention; it also refers to the feeling of pleasure resulting from giving attention to something or from experiencing something. Webster defines interest as "excitement of feeling accompanying special attention to some object; concern; as, an interest in Botany." Thus, this term has been used to refer both to the cause and to the result of giving attention or of experiencing. Using the word in the first sense, we say the boy gets out his blocks because he is interested in building a house, or the little girl makes a doll dress because she is interested in having lots of clothes for her doll. Using it in the second sense, that of a resultant feeling of pleasure, we say the child is interested in playing at building a house or making doll dresses. These two meanings, while diverse, are closely related in the experiences and behavior of the child. Interest which is a result of the feeling of pleasure attendant upon some event or experience tends to condition the child in such a way that he later on does attend to that experience, object, or event because of the pleasure which resulted from previously experiencing or attending to it. This is merely saying that the result of a previous response may be, and frequently is, a present cause of repeating that response. Similarly, a present result may be a future cause. At any rate, interests are motives and often have very strong activating influence on the child's behavior.
Genuine interest is the accompaniment of the identification, through action, of the self with some object or idea, because of the necessity of that object or idea for the maintenance of a self-initiated activity. Effort, in the sense in which it may be opposed to interest, implies a separation between the self and the fact to be mastered or task to be performed, and sets up an habitual division of activities. Externally, we have mechanical habits with no mental end or value. Internally, we have random energy or mind-wandering, a sequence of ideas with no end at all, because they are not brought to a focus in action. Interest, in the sense in which it is opposed to effort, means simply an excitation of the sense organ to give pleasure, resulting in strain on one side and listlessness on the other.
Genuine interest is active, projective, or propulsive, is objective in that it does not end simply in itself, as some feelings may, but involves some object of regard, and is personal, signifying direct concern. The emotional side of interest is quite as significant as its active and objective sides.
Habits, Purposes, and Ideals as Motives
There is another very important factor in the relationship of habit to motivation. If a child has become accustomed or habituated to an excessive amount of some satisfaction he will be strongly motivated to seek it. The child who has been given candy cries for more. Similarly, the youngster who has been petted and protected in too great a degree is likely to spend the rest of his life looking for sympathy and guidance. To be dependent is satisfying for the child, but to have this satisfaction continued into later life is a social handicap.
Purposes and ideals also are motivating forces in the individual's behavior. A small boy may want a wagon, "skate-omobile," or scooter. He asks his father to get it for him, and the father does so. In this instance, little overt behavior is observable that may be attributed to the drive of his desire, want, or purpose. Suppose, however, that the father cannot afford to buy the scooter. The boy, if suitably trained to depend upon himself for the satisfaction of many of his own wants, may hunt about to find the necessary parts, materials, and tools and set to work making his own "skate-o-mobile" or wagon. For hours he may work at it, making many mistakes, bruising his fingers or getting splinters in them, having to try several times before he succeeds. Or the little girl who makes clothes for her doll has many things to learn and may have such high standards of excellence that she literally will work for hours, asking her mother many questions and doing things over and over, before she is satisfied with the result. Even at a younger age, long before children enter first grade, we see evidence of some purpose or, desire activating their behavior, as, for example, when a child of three or four years of age uses some blocks to build a house. The purpose in mind or incentive is not only a motivating force in the child's behavior, but it is also an organizing force through which his activities are integrated in accomplishing a given goal. The formation of suitable purposes and ideals is one of the most significant processes in the development of effective human personality. Reliance upon self in accomplishing many of his purposes is an excellent thing for the child. Even in infancy it seems desirable that the child relieve some of his own wants. If, for example, he is in an uncomfortable and cramped position and begins to cry, his own wriggling, squirming, and thrashing about are likely to overcome his discomfort. He thus learns to adjust independently, instead of expecting assistance. Purposes and ideals of children are likely to be concrete and relatively simple. They are often the expression or outgrowth of their "interests," which are thus also powerful motivating forces.
Social Motives
(1) The need for prestige or the desire for social recognition is a very important social motive. To the stimulus of the presence of other people, the individual acts in such a way as to win attention, approval, and recognition. Much of the child's behavior is activated by this powerful motive. If deprived of the attention of a group, the child "shows off" or becomes noisy. Even serious delinquency may be motivated in this way, as when a youngster seeks to be a "tough guy" in the eyes of other children. On the other hand, some may find apparent modesty, docility, or humility a means of gaining recognition, as in the case of Uriah Heep who boasted of his "'umbleness."
The need for recognition and attention is derived from the satisfaction of the individual's physiological needs in infancy. Whenever ameliorative satisfactions such as those resulting from feeding, warming, or petting are administered, some person is present and is giving attention to the infant. Moreover, these services are frequently accompanied by kind words, regards, and gestures. Learning occurs, which causes the attention of human beings to be esteemed and sought throughout the rest of life.
(2) Another important social motive is the need for security. Persons, and especially children, need to feel that they are wanted and loved, and that they will be cared for. The origin of this motive is very similar to that of prestige and recognition. Because his needs are so great, the infant must depend on others for his welfare. Although constantly modified throughout the various stages of life, the security motive remains a strong one.
(3) The need for pre-eminence or mastery is very marked in child and adult behavior. Persons seek to excel, to get ahead, to worst rivals, and to overcome obstructions. If frustrated in the normal attainment of this goal, they often will assume an excessive aggressiveness toward substitute objects, resulting in bullying, quarrelsomeness, and, in some instances, delinquency.
The pre-eminence motive seems to be based on the rage behavior of infancy. If blocked or restrained in activity, the infant will display an intense emotional reaction and strong uncoordinated activity. Later, other situations come to arouse the same intensely motivated response, as when commands, the competition of other children, or material obstructions to be overcome, restrain him. The motivation, under proper training, is redirected from useless responses into persistence and effort. The pre-eminence desire is a very useful one in human, affairs, motivating desirable forms of ambition and labor as well as the less socialized efforts toward mastery.
(4) Persons are usually strongly motivated toward conformity. They desire to do the expected thing, to have the appearance of other people; they fear to be "different" or to receive scorn or blame. In a sense, this is the converse of the prestige motive but is not merely a passive desire to avoid losing approval. The conformity motive is undoubtedly related to the fear reactions of the infancy period. Whenever an adequate stimulus for fear, such as painful punishment by parents or a pummeling by child associates, is accompanied by blame, criticism, or condemnation, a conditioning occurs. Thereafter, attitudes of expressed or implied criticism tend to arouse the original strong, fear-motivated avoidance reactions. In general, conformity motivation is an inferior form of drive, which might well be eliminated. Social control is as adequately and more humanely achieved through the milder motives of prestige, security, and pre-eminence.
Native and Acquired Factors in Motivation
In the course of the development of motives, external stimuli come to play a larger part, but the essential controlling forces remain those within the organism.
The Modification of Motives
Problems of child behavior are complicated by the inextricable blending of native and acquired elements. Conditioning, learning, and habit formation begin the transformation of native responses immediately after birth. Acquired motives are largely developments from the early native ones, but the origin and development of a motive activating the child at the age of ten or twelve years only rarely can be traced in adequate detail. Habits, purposes, and ideals are still more complex forms of acquired motives, although even in these, the native elements might be found to furnish important parts of the total pattern, if we could only resolve it into its native and acquired components.
We see this process of modifying or conditioning drives in many features of child development, as when some external stimuli are substituted for the earlier internal native ones. Thus, at first the stimuli to play probably come from within, but later external stimulation may set off these activities, as when the child sees other children with whom he plays. The sight or smell of food may come to elicit responses which are aroused originally only by the actual pangs of hunger. Merely thinking about food may start off the flow of saliva which originally was activated, by the sight or smell of food. Thus, organic drives eventuating in positive (or negative) responses may become conditioned to various external stimuli. The sight, taste, smell, color, or merely the idea of an object associated with some unpleasant event may come to arouse the response originally evoked by that event. A child at a very early age is bitten by a large black dog. For years he may be decidedly afraid of dogs, and he may even find himself making incipient negative responses to a wide variety of objects that in some way resemble the black dog. A boy of six stepped on the tail of a sleeping Scotch collie, whereupon the dog lunged for the boy's throat, but jumped too high, sinking his two tusks in the boy's upper lip. For years the boy had a violent fear of large dogs, although he had always played with dogs and continued to play with dogs which were not strange to him. A boy of ten, trying to slide on the ice on a little pond into which refuse from a paper mill was dumped, broke through the thin ice which covered the shallow water and sank in above, his waist. For some minutes he was doubtful of his ability to extricate himself. Finally he got hold of a branch of a small willow tree and pulled himself toward the bank and out of the thick, slimy, vilesmelling, nauseating stuff. He, too, for years, at the sight of any place where the ground was yellowish, which had a small shallow puddle of clear water on part of it, and had a few small straggly willow trees about, not only felt afraid, but also felt strong disgust and some nausea at the anticipated thick, slimy, vile-smelling refuse. Even now, in maturity, although he cannot recall vividly the appearance of the place where he had the unpleasant experience, he occasionally sees a place which he instantly recognizes as like that of the childhood episode, and has some feeling of disgust and aversion.
It is evident from the above instances that the principal mechanism operating in the substitution of motive-stimuli is that of the conditioned reaction. By the simultaneous occurrence of an external stimulus with the original internal or sufficient one, the former becomes capable of evoking the behavior in question. This pattern of learning applies as clearly in the case of motives, likes, aversions, and interests as in simpler muscular or glandular responses.
Another class of stimuli, words, come to act as motives through the operation of the same processes of learning. The development of language permits the visual or auditory symbols of things to function in place of the things themselves. Commands, offers of reward, soothing commendations, all commonly act as motives at the earliest ages in which language is understood. As the child grows older, the motivating power of language symbols increases with his experience with them.
Other Physiological Conditions as Sources of Drives
Change or shifting of attention seems also to be a normal human activity, motivated by the boredom which follows a period of attentive regard (which may be too short for fatigue to enter) or by the urge to active seeking of different perceptual or other fields. Whatever the exact nature of this motive may be, we do not doubt its existence. Such a motive or drive is of inestimable value, insuring a wealth of sensory, perceptual, and other experiences.
Emotion as a Source of Motive
Emotional states constitute another important original source of vigorous and directed, or motivated, behavior. In the two preceding chapters, attention was called frequently to the intense character of the emotional response. An emotional state involves an upset condition of the visceral organs, which, in a sense, is not unlike the conditions found in hunger and the other appetitive drives. This visceral state may act as a strong internal stimulus, impelling the individual to activity.
Strong emotional states of the type of fear and rage are likely to stimulate intense physical activities which are, originally, of an uncoordinated nature. A three-year-old who is angered by another child's appropriating a cherished toy may resort to tears, may hold on to the toy, may try to pull it from the other's hands, or may strike, kick, or shove the offender. He selects one response or another according to the circumstances and his own past experiences, but the emotional state is the motivating factor throughout. As children mature, the character of the outward response to emotion usually becomes modified. A young child who is angered may respond by striking. A few years later, when enraged, he may respond only by angry words and facial expression. As he comes into the teens and social pressure is exerting its influence more effectively, he may respond merely by angry looks. As an adult the individual may not change his expression, but may make a remark that does not reveal the inner turmoil that he feels. Even in this last case, however, the stimulating effect of the emotional state may be present, although held in check, and may lead to the highly pertinent reply.
The milder organic states, such as those elicited by a full stomach, by loving attention, or by certain features of enjoying music or art, are sometimes designated as pleasant or relaxed emotions. These also may have an effect on the motivated behavior of the individual, reducing the activity of skeletal muscles and tending toward repose and compliance. Various internal states, therefore, may have the same effects as tissue needs in stimulating the various reactive mechanisms of the individual. The internal drives based on emotion are of great importance in the development of the social motives and in the mental, hygiene of the individual.
Temperature through the skin, Rest and sleep
The combustion processes of the body produce or liberate a great amount of heat. The metabolic functions of the body require only a small part of it. The remainder is given off, chiefly through the skin. With variations in the temperature surrounding the body, in the amount of clothing, and in internal bodily conditions (as in fever), marked changes occur in the rate of temperature release through the skin. An excessive rate of release or a subnormal rate is a powerful stimulus to activity. Many writers have emphasized the rôle of temperature and humidity upon man's mental and bodily efficiency and cultural development. They have shown that to torrid and arctic regions have not developed a high state of civilization and culture, and that science, literature, and other forms of art have been developed chiefly in the more favorable temperature of the temperate zones.
Unfavorable temperature liberation through the skin as one of the tissue needs giving rise to fundamental drives to overt behavior, resembling in this respect the great drives from hunger, thirst, and elimination. He also points out the place of this drive in seeking and developing shelter and clothing, and suggests that "the gregarious form of life among some animals at least is undoubtedly an outgrowth of unfavorable skin conditions," and that "their original 'sociability' is a huddling together of individuals who have been restlessly moving about until the warmth of each other's bodies furnished enough heat to allow the organism's to come to, rest -- as is easily observed in the nestling together of very young animals."
Rest and sleep
When the striped or skeletal muscles are fatigued the individual seeks rest, and when they are rested he again seeks activity. Activity and rest thus alternate with each other in a rhythm analogous to that of hunger and eating. Rest is a normal need of the organism and may be required by other factors than muscular fatigue alone. The hygiene value of rest and sleep is well known. The alternation of activity and rest is best seen in the case of the heart. The brief rest period after each beat occupies approximately one-third of the time, so that the heart muscle has abundant rest, which enables it to do its work for all the years of life.
That maturation plays a part in rest and sleep is shown by the decreasing amount of sleep needed as the child passes through the stages of infancy, early, middle, and late childhood, adolescence, and maturity. Problems of social control relate to training the child to sleep at times that meet his own needs and fit in with the convenience of the other members of the household. To regard sleep as a pleasure, and not to use it as a punishment seems highly desirable.
Sex
One of the most powerful drives is that of sex. During infancy and childhood the drive is manifested largely in connection with stimulating the erogenous zones and autoeroticism. The child's natural curiosity about sex is stimulated by many conditions and events in the environment. Inhibitions and taboos often repel the child's innocent and perfectly natural questions on sex matters as something nasty, unclean, or "bad," and prevent him from receiving adequate training. Accordingly, we reasonably may expect difficulties in the individual's control of this powerful fundamental drive along socially approved lines.
Thirst, Elimination Sources of Simpler Motives
Drives to overt behavior arise also from dryness of the mucous lining of the mouth and throat. Usually this means also a certain amount of water deficiency in the tissues. Saliva usually keeps the mouth and throat moist. As the body tissues become dehydrated, the saliva is no longer secreted in quantity sufficient to supply moisture to the mouth and throat.
As thirst develops the child or adult becomes restless, and, in fact, shows about the same rhythm phases as in hunger: restlessness, satisfaction, and quiescence. The significance and strength of the drive resulting from this tissue need are similar also to those in the case of hunger. The mechanisms involved are ready to function at birth.
Elimination
Many diverse structures and functional processes are involved in the elimination of waste products from the body. Water is eliminated by the lungs, the kidneys, the skin, and the lower intestine. Carbon dioxide is eliminated by the lungs, soluble salts by the kidneys, salts in solution by the skin, and insoluble waste products by the lower intestine. Of psychological importance are the features of these processes which are subject to modification and control for desirable social development. Breathing and the elimination of waste products by the sweat glands of the skin are well established soon after birth and are little modified by child training except in so far as training in breathing is given for singing, sports, and the like. The eliminative functions involving the bladder and lower bowel are of significance in child training because of their bearing on social adjustments. Adequate control of these processes is necessary for the protection of society, that is, for reasons of sanitation. Their control has significance also because of the social taboos developed about them, such as shame and modesty.
Three phases are observed in the rhythms of bladder and lower bowel elimination, corresponding to those in hunger and thirst. First is the period of accumulating pressure which directly necessitates and stimulates elimination. It is followed by that in which some response is made satisfying the drive. Finally ensues the period of relaxation, rest, or quiescence so far as elimination is concerned. Apparently, sensory experiences are involved, both in the increasing pressure of distention and in the eliminative responses, because voluntary control otherwise would be impossible.
During the first few months of post-natal life these processes are involuntary, but with maturation comes the possibility of developing voluntary control. With increasing age the frequency of these two eliminative responses decreases. The eighth month is usually the time to begin training in voluntary bladder control, and by the age of two years the child normally will be able to keep himself dry in the daytime. Similar control while asleep is not developed so soon, but if training is begun shortly after the end of the first year, control may be expected normally to develop by the end of the third year. Training in voluntary bowel control usually may begin advantageously about the end of the first month, and regular habits may be expected to be established by the end of the third or fourth month. The value of shame as an incentive in developing adequate voluntary control is seriously questioned. Intestinal or digestive difficulties, of course, may be expected to interfere with the regular routine being established for these functions.
Hunger: Physiological Conditions as Sources of Simpler Motives
Hunger
Hunger is caused by contractions of the smooth muscles of the walls of the stomach, which seem to appear and disappear at regular intervals. That they provide a fundamental drive is well known. The hungry person is restless; the hungry infant likewise is restless and given to much overt activity which tends to subside as hunger is satisfied.
The importance of this drive in human history can hardly be overestimated. Food supply, with "fat" and "lean" years, is a fundamental problem in any national economy. In one primitive group fish was very scarce. Stealing fish was punishable by death, although stealing various other things such as another person's wife was not a capital offense. The hunger drive is equally important in the life of the child, with its implications for overt behavior and general bodily vigor.
The whole mechanism for the intake and digestion of food is ready to function at birth. With growth and maturation come changes, as well as through social control. Sometime around the sixth month the teeth begin to erupt, and when this process has proceeded far enough solid foods are included in the diet. Three phases of the hunger rhythm are found from birth. The period of restlessness, already referred to, is evidence of an organic need. Among infants this may be marked also by crying or other evidences of discomfort. This is followed by the responses of feeding -- sucking and swallowing. Then follows the period of quiescence during which the infant sleeps or is active in some way not related to hunger. In children and adults these three phases also are found. The feeding schedule and other features incident to the satisfaction of hunger (use of spoon, cup, etc.) are arranged not only to meet the child's requirements but also to meet those of society. As children develop, problems of poor adjustment may arise over eating, such as eating between meals, poor or irregular appetite, dislike for or refusal to eat certain foods, refusal of any food, refusal to drink from a cup or to feed self, etc. Lack of regular routine probably is responsible more than anything else for wanting to eat between meals and for poor or irregular appetite. On the whole, maladjustments like these seem to be due primarily to poor training; the child has learned the particular undesirable behavior from the training he has had.
What are the fundamental drives in children?
Teachers, parents, and others who guide and direct the behavior of children can do so to best advantage, only if they really understand them. Obviously, such an understanding is dependent upon knowing why the child at a particular time does what he does.
A nine-year-old girl, large for her age, comes home with her best shoes not only covered with mud, but her stockings or socks are also covered with mud halfway to her knees, and splotches of mud are on her dress. The mother has told her "a thousand times" to keep out of the mud and has scolded and punished her for getting her shoes and other clothes muddy. To her the girl's behavior is perverse indeed, and the child may be punished severely for disobeying her mother's previous ultimatum, especially if the mother is crowded with work, has a headache, or is under some other strain. A boy of eight, going to school, takes a short-cut across the corner of a large newly seeded lawn, although he has been told repeatedly to keep out. He is a quiet, well-behaved boy, but persists in cutting across the lawn despite scoldings and threats to notify his parents and the police. Regardless of what is done to handle these two cases, the mother and the lawnowner probably can secure a more effective modification of behavior if they understand why the girl got so muddy and why the boy uses the much objected-to short-cut. The girl, taunted and teased by a young bully's remarks, finally in desperation gives chase through a muddy garden and settles the matter. While on his way to school when in the first grade the boy had been very badly frightened by a cross dog on the next street. He had cut through a vacant lot, and for two years had been going to school this way. A new house had been built and the lot graded and seeded. The boy was still using the accustomed way although the cross dog no longer lived on the next street.
Rational guidance and control of children are contingent upon understanding the motives which activate them.
Some of the earlier attempts at understanding human behavior postulated a series of entities known as instincts which acted as drives, or springs to action. Thus, an individual was said to have a drive or urge to do those things which led to selfpreservation because he had an instinct or instinctive urge of selfpreservation. He was said to want to be with other persons because of the drive from the gregarious or social instinct. If he tore things to pieces this was because of his instinct of destructiveness, or if he put things together in some way it was because of the constructive instinct! On the whole such attempts to understand human motives have not carried us very far. Part of the diffculty, but not all, lies in the fact that the term instinct has been used with at least two diverse meanings. Sometimes it means stimulus arousal of an activity, and sometimes it means a pattern or kind of activity itself. Thus it is used to mean the motivation of an activity, as in pugnacity, curiosity, gregariousnes, parental love, and the like; whereas in other cases it refers to the kind of activity, as when it was alleged that walking, manipulation, collecting, etc., were instincts.
Trying to understand complex human behavior by postulating such entities seems to break down in the study of actual cases. The discussion of mass activity in several previous chapters should make it clear that definite, clear-cut, specific, fixed-inadvance patterns of behavior are rare indeed, and that diffuse, non-specific mass activity is generally the rule, the former developing after experience, learning, or-habit formation has played its part in the infant's development. The definite patterns of response called for by the instinct theory are not found upon careful observation of infants during the first few days or weeks of post-natal life; neither does it seem fruitful to suppose entities (instincts or springs of action) concealed inside us, which, when stimulated, make us do this, that, or some other thing. Such a description of human motivation has little to commend it aside from tradition.
