我们回顾了一系列关于儿童和成人模仿的行为实验，这些实验测试了一种新的模仿理论的预测。大多数最近的模仿理论都假设感知到的动作和模仿的动作之间存在直接的视觉到运动的映射。基于我们对模仿的系统性错误的发现，新的目标导向模仿理论(GOADI)转而假设模仿是由认知上指定的目标引导的。根据GOADI的说法，模仿者并不是作为一个整体来模仿观察到的运动，而是将其分解为单独的方面。这些方面是按层次排列的，最高方面成为模仿者的主要目标。其他方面变成了子目标。根据理想运动原则，主要目标启动与实现这一目标最密切相关的运动方案。当执行时，这个运动程序有时与模特的运动相匹配，有时不匹配。然而，从模型运动中提取的主要目标几乎总是被正确地模仿。
We review a series of behavioural experiments on imitation in children and adults that test the predictions of a new theory of imitation. Most of the recent theories of imitation assume a direct visual-to-motor mapping between perceived and imitated movements. Based on our findings of systematic errors in imitation, the new theory of goal-directed imitation (GOADI) instead assumes that imitation is guided by cognitively specified goals. According to GOADI, the imitator does not imitate the observed movement as a whole, but rather decomposes it into its separate aspects. These aspects are hierarchically ordered, and the highest aspect becomes the imitator's main goal. Other aspects become sub-goals. In accordance with the ideomotor principle, the main goal activates the motor programme that is most strongly associated with the achievement of that goal. When executed, this motor programme sometimes matches, and sometimes does not, the model's movement. However, the main goal extracted from the model movement is almost always imitated correctly.
