青春期性激素对人类性别相关特征的组织影响引起了相当大的兴趣。最近来自啮齿动物的证据表明，在整个青春期，对性激素的敏感性会逐渐降低。如果青春期也代表了人类大脑组织的一个时期，那么在青春期暴露于性典型激素的时间应该对性类型特征有长期影响：早时间的个体应该比晚时间的个体更具有性类型。我们在320名年轻人中测试了这一假设，将他们的青春期时间（与同龄人的回顾性比较）与显示性别差异的认知能力联系起来。结果提供部分支持的假设。对于男性来说，青春期的时间与三维心理旋转测试的分数呈负相关。影响似乎不是由于激素暴露的持续时间（青春期以来的时间），但其他潜在的影响需要进一步研究。(C)2013 Elsevier Inc.

There is considerable interest in the organizational effects of pubertal sex hormones on human sex-related characteristics. Recent evidence from rodents suggests that there is a decreasing window of sensitivity to sex hormones throughout adolescence. If adolescence also represents a period of brain organization in human beings, then the timing of exposure to sex-typical hormones at puberty should have long-term effects on sex-typed characteristics: individuals with early timing should be more sex-typed than individuals with late timing. We tested this hypothesis in 320 young adults by relating their pubertal timing (retrospective comparison to peers) to cognitive abilities that show sex differences. Results provide partial support for the hypothesis. For men, pubertal timing was inversely related to scores on a test of three-dimensional mental rotations. Effects do not appear to be due to duration of hormone exposure (time since puberty), but other potential influences need further study. (C) 2013 Elsevier Inc. All rights reserved.
