In the present study, we investigate whether subliminal complex social cues have an impact on error-monitoring processes. For this purpose, we presented two social status ranks (high and low) with three possible emotional expressions (happy, neutral, angry), using a backward masking paradigm. Participants were instructed to perform a flanker task while recording Event-Related brain Potentials. Results showed larger amplitudes for the Error-Related Negativity index after the presentation of high relative to low social ranks, only for neutral expressions. Neither the angry nor the happy faces induced significant differences in social rank processing. This indicates that subliminal high social ranks, specifically with neutral expressions, increase error processing by boosting attentional control to perform the ongoing task. Our findings extend current knowledge on the automaticity of social and emotional processing and its influence on performance monitoring mechanisms.
