Research on embodied cognition assumes that language processing involves modal simulations that recruit the same neural systems that are usually used for action execution. If this is true, one should find evidence for bidirectional crosstalk between action and language. Using a direct matching paradigm, this study tested if action-languages interactions are bidirectional (Experiments 1 and 2), and whether the effect of crosstalk between action perception and language production is due to facilitation or interference (Experiment 3). Replicating previous findings, we found evidence for crosstalk when manual actions had to be performed simultaneously to action-word perception (Experiment 1) and also when language had to be produced during simultaneous perception of hand actions (Experiment 2). These findings suggest a clear bidirectional relationship between action and language. The latter crosstalk effect was due to interference between action and language (Experiment 3). By extending previous research of embodied cognition, the present findings provide novel evidence suggesting that bidirectional functional relations between action and language are based on similar conceptual-semantic representations.
具身认知研究假设，语言处理涉及模式模拟，这些模拟会调用通常用于执行动作的相同神经系统。如果这是真的，人们应该在动作和语言之间找到双向交流的证据。本研究使用直接匹配范式，检验了动作-语言相互作用是否是双向的（实验 1 和 2），以及动作感知和语言产生之间的交流效应是否是由于促进还是干扰（实验 3）。我们复制了之前的发现，当必须同时进行手动操作和动作词感知（实验 1）时，或者当必须在同时感知手部动作时进行语言表达（实验 2）时，我们发现了交流的证据。这些发现表明动作和语言之间存在明确的双向关系。后一种交流效应是由于动作和语言之间的干扰（实验 3）造成的。通过扩展具身认知的先前研究，本研究结果提供了新的证据，表明动作和语言之间的双向功能关系基于相似的概念-语义表示。
