在心理旋转任务上的性别差异已被反复证明，但在4岁以下儿童中未发现这种差异。为了证明人类婴儿的心理旋转能力，我们让5个月大的婴儿习惯观看一个旋转240°角的物体。在后续的测试试验中，婴儿看到习惯化的物体或其镜像旋转一个之前未见过的120°角。只有男婴似乎能从新的角度识别出熟悉的物体，这一壮举需要心理旋转能力。这些数据为物体在三维空间中心理旋转的性别差异提供了证据，这种差异在成年人群体中一直存在。
A sex difference on mental-rotation tasks has been demonstrated repeatedly, but not in children less than 4 years of age. To demonstrate mental rotation in human infants, we habituated 5-month-old infants to an object revolving through a 240° angle. In successive test trials, infants saw the habituation object or its mirror image revolving through a previously unseen 120° angle. Only the male infants appeared to recognize the familiar object from the new perspective, a feat requiring mental rotation. These data provide evidence for a sex difference in mental rotation of an object through three-dimensional space, consistently seen in adult populations.
