猕猴镜像神经元的发现点燃了人们对包括言语和语言在内的运动认知理论的浓厚兴趣。在这里，我们考察了两个这样的主张，即言语声音的感知关键取决于言语手势的运动表征(言语感知的运动理论)，以及与动作相关的语义知识的表征严重依赖于执行动作所涉及的运动表征。我们的结论是，有强有力的证据反对言语知觉严重依赖于运动系统的说法，也没有确凿证据支持运动系统支持动作语义学的观点。相反，我们提出，知觉过程中与运动相关的活动源于感觉-运动网络中的扩散激活，而感觉-运动网络对言语和语言产生至关重要。
The discovery of mirror neurons in the macaque monkey has ignited intense interest in motor theories of cognition, including speech and language. Here we examine two such claims, that the perception of speech sounds critically depends on motor representations of speech gestures (the motor theory of speech perception) and that the representation of action-related semantic knowledge critically depends on motor representations involved in performing actions. We conclude that there is strong evidence against the claim that speech perception critically depends on the motor system and that there is no conclusive evidence in support of the view that the motor system supports action semantics. We propose instead that motor-related activity during perceptual processes stem from spreading activation in sensory-motor networks that are critical for speech and language production.
