Abstract
Reaction times in simple response time tasks often increase after a participant has made a mistake. The strength of this post-error slowing (PES) effect de- pends on several cognitive mechanisms involved in error processing. This study aimed to replicate and extend Gupta and Deák’s (2015) findings, which sug- gested that PES is influenced by implicit social feedback, particularly facial ex- pressions. In this experiment, 40 participants completed a line judgment task while task-irrelevant facial expressions (happy, neutral, sad, and disgusted) were briefly presented after correct and incorrect responses. We hypothesized that the magnitude of PES would vary based on the valence of the facial feed- back, with stronger effects expected for incongruent (e.g., happy after an error) or congruent (e.g., disgusted after an error) feedback as opposed to neutral feedback. We found significant PES but failed to replicate the interaction be- tween facial expressions and PES. There was no significant difference in PES be- tween different facial expressions. The results suggests that while PES is a ro- bust phenomenon, its modulation by implicit social feedback may be less con- sistent than previously observed. The findings contribute to the impact of social feedback on error processing. They highlight the need for additional studies in- vestigating this relationship, as we failed to replicate previous studies.
