分析羊水中胎儿睾酮(FT)水平。出生后，这些婴儿(29名女孩和41名男孩)和父母在12个月大时被拍摄下来，并记录婴儿与父母的眼神接触量。女孩比男孩进行更多的眼神交流。这重复了之前的研究，这些研究表明女性在社交方面更具优势，尤其是眼神交流。当两个性别的数据一起检查时，以及当男孩的数据单独检查时，眼神接触量与胎儿睾酮水平呈二次曲线变化。这表明胎儿睾丸激素可能塑造了社会发展的神经机制。(C)2002 Elsevier Science Inc.保留所有权利。
Amniotic fluid was analysed for foetal testosterone (FT) level. Postnatally, the infants (29 girls and 41 boys) and parents were filmed at 12 months of age, and the amount of eye contact made by the infant to the parent was recorded. Girls made significantly more eye contact than boys. This replicates previous studies showing a female superiority in sociality more broadly, and eye contact in particular. The amount of eye contact varied quadratically with foetal testosterone level when data from both sexes was examined together, and when the data for the boys was examined alone. This suggests that foetal testosterone may shape the neural mechanisms underlying social development. (C) 2002 Elsevier Science Inc. All rights reserved.
