先前的研究已经反复证明，类人物体的心理旋转比抽象物体的心理旋转要快得多（一种身体类比效应）。根据现有的说法，身体类比效应是通过将自己的身体轴投射到物体上（空间体现）和对观察到的身体姿势的心理模拟（运动体现）来调节的。为了测试运动体现是否能促进类人物体的心理旋转，我们用一个有自己身体轴但难以模仿的类蛇物体进行了一个实验。24名参与者对有或没有蛇脸的蛇形立方体以及有或没有人脸的人形立方体进行了心理旋转。结果表明，人脸的存在增加了人形和蛇形立方体的心理旋转速度，证实了人体和蛇的类比效应。更重要的是，蛇的类比效应等于人体的类比效应。这些发现与运动体现的解释相矛盾，并表明任何可以被视为一个单元的物体都可以促进整体的心理旋转，从而提高表现。
Previous research has demonstrated repeatedly that the mental rotation of human-like objects can be performed more quickly than the mental rotation of abstract objects (a body analogy effect). According to existing accounts, the body analogy effect is mediated by projections of one's own body axes onto objects (spatial embodiment), and the mental emulation of the observed body posture (motoric embodiment). To test whether motoric embodiment facilitates the mental rotation of human-like objects, we conducted an experiment using a snake-like object that had its own body axes but would be difficult to emulate. Twenty-four participants performed the mental rotation of snake-shaped cubes with or without a snake face as well as human-shaped cubes with or without a human face. Results showed that the presence of a face increased mental rotation speeds for both human-shaped and snake-shaped cubes, confirming both the human-body and snake analogy effects. More importantly, the snake analogy effect was equal to the human-body analogy effect. These findings contradict the motoric embodiment account and suggest that any object that can be regarded as a unit facilitates holistic mental rotation, which in turn leads to improved performance.
