Introduction to the Science of Sociology

by Robert Ezra Park; E. W. Burgess

Differences between the sexes have been established also by means of experimental psychology, based upon the examination of a very large number of instances. Berthold Hartmann has studied the childish circle of thought, by means of a series of experiments. Schoolboys to the number of 660 and schoolgirls to the number of 652, at ages between five and three-fourths and six and three-fourths years, were subjected to examination. It was very remarkable to see how, in respect to certain ideas, such as those of the triangle, cube, and circle, the girls greatly excelled the boys; whereas in respect of animals, minerals, and social ideas, the boys were better informed than the girls. Characteristic of the differences between the sexes, according to Meumann, from whom I take these details and some of those that follow, is the fact that the idea of "marriage" was known to only 70 boys as compared to 227 girls; whilst the idea of "infant baptism" was known to 180 boys as compared to 220 girls. The idea of "pleasure" was also much better understood by girls than by boys. Examination of the memory has also established the existence of differences between the sexes in childhood. In boys the memory for objects appears to be at first the best developed; to this succeeds the memory for words with a visual content; in the case of girls, the reverse of this was observed. In respect of numerous details, however, the authorities conflict. Very striking is the fact, one upon which a very large number of investigators are agreed, that girls have a superior knowledge of colors.

There are additional psychological data relating to the differences between the sexes in childhood. I may recall Stern's investigations concerning the psychology of evidence, which showed that girls were much more inaccurate than boys.

It has been widely assumed that these psychical differences between the sexes result from education, and are not inborn. Others, however, assume that the psychical characteristics by which the sexes are differentiated result solely from individual differences in education. Stern believes that in the case of one differential character, at least, he can prove that for many centuries there has been no difference between the sexes in the matter of education; this character is the capacity for drawing. Kerschensteiner has studied the development of this gift, and considers that his results have established beyond dispute that girls are greatly inferior in this respect to boys of like age. Stern points out that there can be no question here of cultivation leading to a sexual differentiation of faculty, since there is no attempt at a general and systematic teaching of draughtsmanship to the members of one sex to the exclusion of members of the other.

I believe that we are justified in asserting that at the present time the sexual differentiation manifested in respect of quite a number of psychical qualities is the result of direct inheritance. It would be quite wrong to assume that all these differences arise in each individual in consequence of education. It does, indeed, appear to me to be true that inherited tendencies may be increased or diminished by individual education; and further, that when the inherited tendency is not a very powerful one, it may in this way even be suppressed.

We must not forget the frequent intimate association between structure and function. Rough outdoor games and wrestling thus correspond to the physical constitution of the boy. So, also, it is by no means improbable that the little girl, whose pelvis and hips have already begun to indicate by their development their adaption for the supreme functions of the sexually mature woman, should experience obscurely a certain impulsion toward her predestined maternal occupation, and that her inclinations and amusements should in this way be determined. Many, indeed, and above all the extreme advocates of women's rights, prefer to maintain that such sexually differentiated inclinations result solely from differences in individual education: if the boy has no enduring taste for dolls and cooking, this is because his mother and others have told him, perhaps with mockery, that such amusements are unsuited to a boy; whilst in a similar way the girl is dissuaded from the rough sports of boyhood. Such an assumption is the expression of that general psychological and educational tendency, which ascribes to the activity of the will an overwhelmingly powerful influence upon the development of the organs subserving the intellect, and secondarily also upon that of the other organs of the body. We cannot dispute the fact that in such a way the activity of the will may, within certain limits, be effective, especially in cases in which the inherited tendency thus counteracted is comparatively weak; but only within certain limits. Thus we can understand how it is that in some cases, by means of education, a child is impressed with characteristics normally foreign to its sex; qualities and tendencies are thus developed which ordinarily appear only in a child of the opposite sex. But even though we must admit that the activity of the individual may operate in this way, none the less we are compelled to assume that certain tendencies are inborn. The failure of innumerable attempts to counteract such inborn tendencies by means of education throws a strong light upon the limitations of the activity of the individual will; and the same must be said of a large number of other experiences.

Criminological experiences appear also to confirm the notion of an inherited sexual differentiation, in children as well as in adults. According to various statistics, embracing not only the period of childhood, but including as well the period of youth, we learn that girls constitute one-fifth only of the total number of youthful criminals. A number of different explanations have been offered to account for this disproportion. Thus, for instance, attention has been drawn to the fact that a girl's physical weakness renders her incapable of attempting violent assaults upon the person, and this would suffice to explain why it is that girls so rarely commit such crimes. In the case of offenses for which bodily strength is less requisite, such as fraud, theft, etc., the number of youthful female offenders is proportionately larger, although here also they are less numerous than males of corresponding age charged with the like offenses. It has been asserted that in the law courts girls find more sympathy than boys, and that for this reason the former receive milder sentences than the latter; hence it results that in appearance merely the criminality of girls is less than that of boys. Others, again, refer the differences in respect of criminality between the youthful members of the two sexes to the influences of education and general environment. Morrison, however, maintains that all these influences combined are yet insufficient to account for the great disproportion between the sexes, and insists that there exists in youth as well as in adult life a specific sexual differentiation, based, for the most part, upon biological differences of a mental and physical character.

Such a marked differentiation as there is between the adult man and the adult woman certainly does not exist in childhood. Similarly in respect of many other qualities, alike bodily and mental, in respect of many inclinations and numerous activities, we find that in childhood sexual differentiation is less marked than it is in adult life. None the less, a number of sexual differences can be shown to exist even in childhood; and as regards many other differences, though they are not yet apparent, we are nevertheless compelled to assume that they already exist potentially in the organs of the child.

6. Racial Differences[63]

The results of the Cambridge expedition to the Torres Straits have shown that in acuteness of vision, hearing, smell, etc., these peoples are not noticeably different from our own. We conclude that the remarkable tales adduced to the contrary by various travelers are to be explained, not by the acuteness of sensation, but by the acuteness of interpretation of primitive peoples. Take the savage into the streets of a busy city and see what a number of sights and sounds he will neglect because of their meaninglessness to him. Take the sailor whose powers of discerning a ship on the horizon appear to the landsman so extraordinary, and set him to detect micro-organisms in the field of a microscope. Is it then surprising that primitive man should be able to draw inferences which to the stranger appear marvelous, from the merest specks in the far distance or from the faintest sounds, odors, or tracks in the jungle? Such behavior serves only to attest the extraordinary powers of observation in primitive man with respect to things which are of use and hence of interest to him. The same powers are shown in the vast number of words he will coin to denote the same object, say a certain tree at different stages of its growth.
