本实验探讨了9个月大婴儿的心理旋转能力是否与其爬行和手动探索物体的能力有关。48名9个月大的婴儿接受了测试，其中一半的婴儿平均爬行时间为9.3周。婴儿习惯于一个简化的Shepard-Metzler物体的视频，该物体围绕物体的纵轴来回旋转240°角。他们用同一物体旋转120°的视频和显示器的镜像进行了测试。所有的婴儿还参与了一个手动物体探索任务，在这个任务中，他们自由地探索五个玩具块。结果表明，爬行者在新的（镜像）物体上看的时间明显长于熟悉的物体，与他们的手动探索分数无关。相比之下，非爬行者的寻找时间受到手动探索分数的影响。没有自发探索积木的婴儿倾向于表现出熟悉的偏好，而那些探索积木的婴儿更喜欢看新的物体。因此，所有的婴儿都能够掌握心理旋转任务，但对于没有爬行经验和不会自发探索物体的婴儿来说，这似乎是最复杂的过程。
The present experiment examined whether the mental rotation ability of 9-month-old infants was related to their abilities to crawl and manually explore objects. Forty-eight 9-month-old infants were tested; half of them had been crawling for an average of 9.3 weeks. The infants were habituated to a video of a simplified Shepard–Metzler object rotating back and forth through a 240° angle around the longitudinal axis of the object. They were tested with videos of the same object rotating through a previously unseen 120° angle and with a mirror image of the display. All of the infants also participated in a manual object exploration task, in which they freely explored five toy blocks. The results showed that the crawlers looked significantly longer at the novel (mirror) object than at the familiar object, independent of their manual exploration scores. The non-crawlers looking times, in contrast, were influenced by the manual exploration scores. The infants who did not spontaneously explore the toy blocks tended to show a familiarity preference, whereas those who explored the toy blocks preferred to look at the novel object. Thus, all of the infants were able to master the mental rotation task but it seemed to be the most complex process for infants who had no crawling experience and who did not spontaneously explore objects.
