According to the embodied cognition perspective, cognitive systems and perceptuo-motor systems are deeply intertwined and exert a causal effect on each other. A prediction following from this idea is that cognitive activity can result in subtle changes in observable movement. In one experiment, we tested whether reading various sentences resulted in changes in postural sway. Sentences symbolized various human activities involving high, low, or no physical effort. Dutch participants stood upright on a force plate, measuring the body center of pressure, while reading a succession of sentences. High physical effort sentences resulted in more postural sway (greater ) than low physical effort sentences. This effect only showed up in medio-lateral sway but not anterio-posterior sway. This suggests that sentence comprehension was accompanied by subtle motoric activity, likely mirroring the various activities symbolized in the sentences. We conclude that semantic processing reaches the motor periphery, leading to increased postural activity.
根据具身认知观点，认知系统与感知运动系统紧密相连且相互产生因果影响。基于这一观点的一个预测是，认知活动会导致可观察到的运动发生细微变化。在一项实验中，我们测试了阅读不同的句子是否会导致姿势摆动的变化。句子象征着各种涉及高、低或无体力消耗的人类活动。荷兰参与者站在测力板上直立，测量身体压力中心，同时阅读一系列句子。与低体力消耗的句子相比，高体力消耗的句子导致更多的姿势摆动（更大）。这种效应仅在左右摆动中出现，而在前后摆动中未出现。这表明句子理解伴随着细微的运动活动，可能反映了句子中象征的各种活动。我们得出结论，语义处理会延伸到运动外周，导致姿势活动增加。
