众所周知，感知视觉对象和阅读对象名称都会自动激活相关的运动代码并调节运动反应。我们研究了不同效应器（手和脚）的这些运动激活效应的性质，以及图片和文字，在整个反应的时间过程中。由对象和单词引起的兼容性效应的平均效应大小是可比的，都是更大的慢比快的反应和刺激类型之间的影响呈正相关。我们的研究结果支持一个具体的认知帐户，其中的感知对象和文字自动激活感知模拟相关的行动，这表明，对象和文字共享认知和神经机制访问运动代码。然而，对象和单词的兼容性效应在不同的试验中进行：单词的兼容性效应对先前的反应敏感，而对象的效果则更不受这种影响。这一结果表明，物体和动作之间通过视觉途径的联系比通过语言途径的联系更强。
It is known that both perceiving visual objects and reading object names automatically activate associated motor codes and modulate motor responses. We examined the nature of these motor activation effects for different effectors (hands and feet), and for pictures and words, across the time course of responding. The compatibility effects elicited by objects and words were comparable for the mean effect size, both were larger for slow than for fast responses and the effects were positively correlated across the stimulus types. Our results support an embodied cognition account in which the perception of objects and words automatically activates perceptual simulations of the associated actions, suggesting that objects and words share cognitive and neural mechanisms for accessing motor codes. However, the compatibility effects for objects and words carried over across trials differently: the compatibility effect for words was sensitive to a previous response, while the effect for objects was more immune to such influence. This result suggests a stronger link between objects and actions through a visual pathway than through a linguistic pathway.
