对他人行为的观察促进了观察者的类似行为。这种启动效应可以通过观察者和被观察者在以身体为中心或空间坐标（或两者兼而有之）的对齐来驱动。这些启动源的单独和共同贡献仍有待充分描述。在这里，我们通过使用手和脚的反应，比较了整个身体“空间”的空间和身体启动效应。这使得身体启动和空间启动的分离比以前的研究更清晰。此外，我们还展示了这些动作启动效应的两个进一步特征。首先，当观看的显示器的布局与参与者的身体匹配时（例如手高于脚），会产生一般的干扰和促进效应。这些影响在以前的研究中没有被考虑到。其次，通过考虑这些布局效应，我们确定了空间和身体启动效应的促进和干扰成分。这两种类型的启动效应都可以被观察到，而促进效应和干扰效应只有在身体和空间参考框架在同一方向上工作时才会被观察到。这些发现表明，在动作感知中，他人的行为在多个参照系中同时被处理，这些参照系对观察者的运动系统有复杂的相互作用，既有促进作用，也有干扰作用。
The observation of someone else’s action facilitates similar actions in the observer. Such priming effects can be driven by alignment between the observer and the observed in body-centred or spatial coordinates (or both). The separate and joint contributions of these sources of priming remain to be fully characterised. Here, we compare spatial and body priming effects across the whole body “space”, by using hand and foot responses. This allows a clearer separation of body priming from spatial priming than available from previous studies. In addition, we demonstrate two further features of these action priming effects. First, there are general interference and facilitation effects when the layout of viewed displays matches the participant’s body (e.g. hand above the foot). These effects have not been considered in previous studies. Second, by taking these layout effects into account, we identify the facilitation and interference components of spatial and body priming effects. Both types of priming effect are observed, and facilitation and interference effects are only observed when both body and spatial frames of reference are working in the same direction. These findings show that in action perception, the behaviours of others are processed simultaneously in multiple frames of reference that have complex, interacting effects—both facilitating and interfering—on the motor system of the observer.
