Situations restructure the congruency between action and valence in the action-evaluation effect

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.
