Emotion in action: A study on the enactment effect on emotional action sentences

While abundant literature suggests that both performing congruent actions and emotional stimuli can enhance memory, their combined impact on memory for action phrases remains underexplored. This study investigated the effects of enactment with emotionally charged stimuli on memory performance. Sixty participants encoded action sentences with negative, neutral, or positive emotional connotations using either enactment or verbal-reading methods. Memory performance was assessed through immediate free recall tasks and a delayed yes-no recognition task. Results demonstrated a significant memory advantage for action-enacted sentences compared to verbal reading in recall and recognition tasks. Moreover, recall accuracy was higher for negative action sentences, while recognition performance was enhanced for negative and positive sentences. No interaction was found between encoding type and emotional connotation in memory tasks. Our findings revealed that both enactment and valence independently enhance memory performance, extending the benefits of enactment to emotional stimuli. Furthermore, our results highlight the differential effects of valence on free recall and recognition tasks, suggesting task-specific processes related to memory for negative and positive stimuli.
