Behavioral differences between the sexes include methods of carrying books. Females clasp books against their chests; males carry them at their sides. In kindergarten and the first grade, both sexes carry like mature males. Sex-typical carrying appears before adolescence. Behavioral differences seem to be primarily a consequence of morphological differences and social modeling.
