Error-monitoring across social and affective processing contexts

Area of Science:

• Neuroscience
• Cognitive Psychology
• Affective Science

Background:

• The error-related negativity (ERN) is a key neural marker for cognitive control and error monitoring.
• Existing ERN research often uses neutral stimuli, limiting understanding of affect's role in error processing.
• Affective and social stimuli can be integrated into cognitive tasks to explore their impact on error monitoring.

Purpose of the Study:

• To investigate if affective and social stimuli elicit expected behavioral and psychophysiological error-monitoring responses.
• To adapt the arrow flanker task to incorporate diverse stimuli (arrows, faces, pleasant/unpleasant images).
• To examine the influence of emotional content on error-related negativity (ERN) and cognitive control.

Main Methods:

• A within-subjects design was used, administering four flanker tasks with different stimuli: arrows, neutral faces, unpleasant images, and pleasant images.
• Behavioral data (accuracy, reaction time) and electrophysiological data (ERN) were collected.
• Analyses focused on comparing congruent versus incongruent trials and error versus correct trials across stimulus types.

Main Results:

• Arrow and face flanker tasks showed expected behavioral patterns and ERN modulation.
• Unpleasant and pleasant stimuli also modulated the ERN, but behavioral effects were less consistent.
• The ERN was larger for incongruent trials involving affective stimuli suppression.
• Individual differences in ERN and behavior varied across tasks, with significant task-specific variance.

Conclusions:

• Modifying classic error-monitoring tasks with affective stimuli is feasible and provides insights into emotion's role in cognitive control.
• This approach can better target social and affective constructs relevant to clinical research.
• Affective stimuli influence error monitoring, suggesting a more integrated model of cognitive and affective processes.
