The action-evaluation effect indicates that the processing of affective valence is affected by bodily actions. However, whether this effect is based on bodily simulation or situational priming is unknown. Moreover, P2 is a neural marker for this effect, suggesting the integration between valence and actions. Whether the P2 component is modulated by the situation is also unknown. In this study, we tested this effect in multiple situations to examine (1) whether this effect is dependent on the situation and (2) the amplitude of P2 is modulated by the situation. During the experiments, participants pushed/pulled computer mice to verify the valence of affective words in far-near (Experiment 1), front-back (Experiments 2a-2b), and up-down (Experiments 3a-3b) situations. Pulling (or pushing) mice responding to positive (or negative) words were treated as the congruent condition, while the opposite combination was the incongruent condition. In the far-near situation, participants' response times were faster and the amplitude of the P2 component was smaller in the congruent condition than the incongruent one; however, these results were reversed in other situations. The results suggested that the congruency of action-evaluation effect was restructured by the situation. Therefore, the action-evaluation effect might be based on situational priming.
动作-评价效应表明，情感效价的加工受到身体动作的影响。然而，这种效应是基于身体模拟还是情境启动尚不清楚。此外，P2是这种效应的神经标志物，表明效价与动作之间的整合。P2成分是否受情境调节也不清楚。在本研究中，我们在多种情境下测试了这种效应，以检验：（1）这种效应是否依赖于情境；（2）P2的波幅是否受情境调节。在实验过程中，参与者推拉电脑鼠标，以验证情感词在远近（实验1）、前后（实验2a - 2b）和上下（实验3a - 3b）情境中的效价。将拉动（或推动）鼠标以回应积极（或消极）词汇的情况视为一致条件，而相反的组合则为不一致条件。在远近情境中，与不一致条件相比，一致条件下参与者的反应时间更快，P2成分的波幅更小；然而，在其他情境中这些结果则相反。结果表明，动作-评价效应的一致性受情境重构。因此，动作-评价效应可能基于情境启动。
