本研究探讨胎儿睾酮（fT）水平（测量羊水）作为一个候选的生物因素，影响性别差异系统化。系统化是一个认知过程，被定义为分析或构建系统的驱动力。最近的一个心理性别差异模型表明，这是性别差异的一个主要方面，男性比女性更倾向于系统化。参与者包括204名儿童（93名女性），年龄6-9岁，参加了一项关于M的影响的长期研究。向这些母亲提供系统化商数-儿童版，以代表他们的孩子回答。男性（平均值= 27.79 +/- 7.64）的得分明显高于女性（平均值= 22.59 +/- 7.53），这证实男孩比女孩更能系统地学习。逐步回归分析显示，fT是唯一显着的预测系统化偏好时，性别一起检查。性别不包括在最后的回归模型，这表明Er水平发挥更大的作用比孩子的性别在系统化偏好的差异。本研究表明，fT水平是影响认知性别差异的生物学因素，并支持性别差异的移情-系统化理论。
This study examines foetal testosterone (fT) levels (measured in amniotic fluid) as a candidate biological factor, influencing sex differences in systemizing. Systemizing is a cognitive process, defined as the drive to analyze or construct systems. A recent model of psychological sex differences suggests that this is a major dimension in which the sexes differ, with males being more drawn to systemize than females. Participants included 204 children (93 female), age 6-9 years, taking part in a long-term study on the effects of M The systemizing quotient - children's version was administered to these mothers to answer on behalf of their child. Males (mean = 27.79 +/- 7.64) scored significantly higher than females (mean = 22.59 +/- 7.53), confirming that boys systemize to a greater extent than girls. Stepwise regression analysis revealed that fT was the only significant predictor of systemizing preference when the sexes were examined together. Sex was not included in the final regression model, suggesting that Er levels play a greater role than the child's sex in terms of differences in systemizing preference. This study suggests that the levels of fT are a biological factor influencing cognitive sex differences and lends support to the empathizing-systemizing theory of sex differences.
