Zusammenfassung
Theories on conflict control assume that the detection of response conflict leads to increased conflict resolution on the subsequent trial. For emotion-mediated response conflicts, it has been suggested that conflict resolution acts by suppressing activity in the amygdala. However, many studies have shown that emotional stimuli are preferentially processed already in early sensory pathways. Based on these findings, the present fMRI-study investigated whether emotion-mediated response conflict is also resolved by reducing preferential sensory processing of emotional pictures. Participants discriminated between emotional words while ignoring simultaneously presented face distractors. These included neutral, as well as emotional facial expressions which were either congruent or incongruent to the target word. Preferential processing of emotional stimuli was measured as enhanced BOLD-activity when comparing emotional to neutral face distractors. Results indicate that enhanced processing of emotional faces in early visual pathways is eliminated following response conflict. This suggests that emotionmediated response conflict is resolved by reducing preferential sensory processing of emotional stimuli.
