quiet until these latter had been duly
admired. The love of self-adornment is almost peculiar to female
children; boys, on the other hand, prefer rough outdoor games, in which
their muscles are actively employed, robber-games, soldier-games, and
the like. And whereas, in early childhood, both sexes are fond of very
noisy games, the fondness for these disappears earlier in girls than in
boys.

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 indivi
