Feeling bad about being wrong: Affective evaluation of performed actions and its trial-by-trial relation to autonomic arousal.

Research on action monitoring and error processing has begun to consider the role of emotion, motivation, and peripheral autonomic arousal. To date, little is known about the specific nature of evaluative processing during action monitoring and its interaction with autonomic arousal. This study aimed to replicate and extend previous findings on affective action evaluation and to examine trial-level associations between action evaluation and autonomic arousal. Thirty participants performed an affective priming paradigm, consisting of a go/no-go task with an embedded word categorization task, while skin conductance response (SCR) was recorded. After each motor response in the go/no-go task, participants categorized an affective word as positive or negative. Using mixed-effects modeling, we replicated previous evidence of action-based affective priming, in that false alarms in the go/no-go task were followed by faster and more accurate categorization of negative compared with positive words, whereas hits were followed by faster categorization of positive compared with negative words. We found no evidence for a trial-level association between this priming effect and SCR. Instead, errors increased SCR and its magnitude predicted post-error slowing (PES) on a trial-by-trial level, in line with an orienting account of PES. Our findings support the notion that valence values are assigned to own performed actions, with incorrect actions being evaluated as negative events and correct actions as positive events. Our results further suggest that this valence evaluation might operate independently of arousal-related processes during action monitoring, indicating that these processes might serve different roles in promoting adaptive behavior.
