通常假设动作感知和物体识别受到大脑中功能和神经解剖学上不同的处理流的促进。然而，最近的证据挑战了这种经典观点，并表明两种视觉处理流之间存在相互作用。虽然之前的研究表明对象感知对动作相关任务的影响，但我们研究了动作表征是否促进视觉对象识别。为了解决这个问题，两个简短显示的蒙版物体被依次呈现，要么提供一致的运动交互，要么提供不一致的运动交互。我们发现，与不一致的运动交互相比，一致的对象对的命名准确性更高（实验 1）。这种动作启动效应表明动作表征可以促进物体识别。我们进一步研究了这种行动启动效应背后的表征的本质。当主要刺激以单词形式呈现时，效果不存在（实验 2）。因此，动作启动效应似乎依赖于视觉对象信息指定的动作表征。我们的研究结果表明，面向对象的行动过程会影响对象识别。
It is typically assumed that perception for action and object recognition are subserved by functionally and neuroanatomically distinct processing streams in the brain. However, recent evidence challenges this classical view and suggests an interaction between both visual processing streams. While previous studies showed an influence of object perception on action-related tasks, we investigated whether action representations facilitate visual object recognition. In order to address this question, two briefly displayed masked objects were sequentially presented, either affording congruent or incongruent motor interactions. We found superior naming accuracy for object pairs with congruent as compared to incongruent motor interactions (Experiment 1). This action priming effect indicates that action representations can facilitate object recognition. We further investigated the nature of the representations underlying this action priming effect. The effect was absent when the prime stimulus was presented as a word (Experiment 2). Thus, the action priming effect seems to rely on action representations specified by visual object information. Our findings suggest that processes of object-directed action influence object recognition.
