人类婴儿接受了两项认知测试的训练，这些测试此前已揭示，在婴儿猴中，双重解离可以通过围产期雄激素的操纵和特定大脑部位的消融来逆转。儿童表现出与幼猴相同的性别相关行为：小男孩在对象反转任务中表现出色，而年轻女孩在同时辨别任务中表现出色。正如之前在小猴子身上发生的那样，性别差异在老年人类受试者中并不明显。因此，在个体发育早期，人类和猴子都发现了认知性别差异，这可能是影响特定大脑系统成熟率的雄激素性别差异的结果。
Infant humans were trained on 2 cognitive tests that have previously revealed, in infant monkeys, a double dissociation that was reversible by perinatal manipulations of androgens and ablations of specific brain sites. Children showed the same sex-linked behavior found with infant monkeys: young boys were superior on the object reversal task and young girls were superior on the concurrent discrimination task. As happened previously with infant monkeys, the gender difference was not apparent in older human subjects. Thus, early in ontogeny, cognitive gender differences have now been discovered in both humans and monkeys, probably a result of gender differences in androgens that influence the maturation rate of specific brain systems.
