研究人员对3到4个月大的男女婴儿进行了一项二维心理旋转任务，类似于对年龄较大的儿童和成人进行的任务。婴儿在0度和360度之间的7个不同的旋转中熟悉数字1（或其镜像），然后用熟悉的刺激与其镜像配对的新旋转进行偏好测试。男性婴儿表现出一种新奇的偏好，镜像刺激的熟悉的刺激的新旋转，而女性之间的两个测试刺激的注意力。结果表明，心理旋转的性别差异在早期就出现了。
Three- to 4-month-old female and male human infants were administered a two-dimensional mental-rotation task similar to those given to older children and adults. Infants were familiarized with the number 1 (or its mirror image) in seven different rotations between 0 degrees and 360 degrees, and then preference-tested with a novel rotation of the familiar stimulus paired with its mirror image. Male infants displayed a novelty preference for the mirror-image stimulus over the novel rotation of the familiar stimulus, whereas females divided attention between the two test stimuli. The results point toward an early emergence of a sex difference in mental rotation.
