通过考虑他人的观点来评估他人的心理状态在社会交往中起着重要的作用。基于视觉信息的模仿是将感官输入转化为行动的典型案例。虽然人类经常成功地模仿复杂的动作，但成功模仿的机制却知之甚少。在早期的研究中，有人认为，通过模仿来理解他人的思想是在自我和他人的表征之间进行比较的过程中实现的，这涉及到自我中心视角到他者中心视角的转变。自我表征与他人表征之间的转换有两种可能的策略。一种可能的情况是，模仿者感知和模仿他人，就像在看镜子一样（镜像模仿，例如，演示者的右手对应于模仿者的左手）。或者，模仿者可能会使用解剖学上一致的肢体来估计演示者的动作（解剖学模仿，例如，演示者的右手对应于模仿者的右手）。在这里，我们进行了一系列的实验中，受试者模仿简单的手的动作，如按下一个按钮，从几个不同的空间方向旋转在不同的角度。我们观察到，模仿者改变他们的模仿策略（镜像或解剖模仿）取决于空间配置的性质。这项研究的行为数据支持这一假设，即镜像和解剖模仿提供了理解他人行为和意图的互补系统。
Assessing the mental state of others by considering their perspective plays an important part in social communication. Imitation based on visual information represents a typical case of the translation of sensory input into action. Although humans are often successful in imitating complex actions, the mechanisms that underlie successful imitation are poorly understood. In earlier findings, it has been suggested that understanding others’ minds through imitation is realized in the course of the comparison between the representations of the self and others, involving a transformation of the egocentric perspective to the allocentric one. There are two possible strategies of transformation between the representation of the self and others. One possible scenario is that the imitator perceives and imitates others as if looking in a mirror (mirror-image imitation, where, for example, the demonstrator’s right hand corresponds to the imitator’s left hand). Alternatively, the imitator might estimate the demonstrator’s action using the anatomically congruent limb (anatomic imitation, where, for example, the demonstrator’s right hand corresponds to the imitator’s right hand). Here, we conducted a series of experiments in which the subjects imitated simple hand actions such as pushing a button presented from several different spatial orientations rotated at various angles. We observed that the imitators changed their strategy of imitation (mirror-image or anatomic imitation) depending on the nature of spatial configurations. Behavioral data from this study support the hypothesis that mirror-image and anatomic imitations provide complementary systems for understanding the actions and intentions of others.
