本研究调查了7-10岁儿童（35名男孩，29名女孩）中，从孕中期羊水中测量的胎儿睾酮（FT）是否与视觉空间能力的特定方面相关。一系列的任务：儿童的嵌入图形测试（EFT）（注意细节的测试），球瞄准任务（测量手眼协调），和计算机化的心理旋转任务（测量旋转能力）。FT是一个显着的预测EFT分数在男孩和女孩，男孩也表现出明显的优势，这项任务。在目标方面没有观察到显著的性别差异。男生在心理旋转上的得分高于女生。然而，没有显着的关系，观察到FT和目标或心理旋转。女童在心理旋转和目标任务上的表现与年龄显著相关，表明这些任务对年龄较小的儿童来说可能太难了。这些结果表明，FT在认知发展的某些方面有显着的作用，但需要进一步的工作，以了解其对视觉空间能力的不同方面的影响。
This study investigated whether fetal testosterone (FT) measured from second trimester amniotic fluid was related to specific aspects of visuospatial ability, in children aged 7-10 years (35 boys, 29 girls). A series of tasks were used: the children's Embedded Figures Test (EFT) (a test of attention to detail), a ball targeting task (measuring hand-eye coordination), and a computerized mental rotation task (measuring rotational ability). FT was a significant predictor for EFT scores in both boys and girls, with boys also showing a clear advantage for this task. No significant sex differences were observed in targeting. Boys scored higher than girls on mental rotation. However, no significant relationships were observed between FT and targeting or mental rotation. Girls' performance on the mental rotation and targeting tasks was significantly related to age, indicating that these tasks may have been too difficult for the younger children. These results indicate that FT has a significant role in some aspects of cognitive development but that further work is needed to understand its effect on the different aspects of visuospatial ability.
