Sequential and domain-specific processing mechanisms for dual cognitive-emotional conflict.

Abstract

This study aimed to investigate how the cognitive control system resolves conflicts when cognitive and emotional conflicts occur simultaneously, and how it performs. To achieve this, a factorial task-crossing design was employed, combining the spatial Simon task and the face-word emotional interference task, allowing cognitive and emotional conflicts to occur concurrently within a single trial. The results revealed that the Simon cognitive conflict was only associated with N2 and early SP, while it did not affect the amplitude of N450 and late SP. Conversely, the face-word emotional conflict affected the amplitude of N450 and late SP, but had no impact on N2 and early SP. These findings demonstrate the adaptive sequencing organization and domain specificity in cognitive-emotional dual conflict processing, which reflects the precise and flexible orchestration and strategic adjustments of the cognitive control system. The results contribute to a better understanding of the dynamic and temporal processes involved in the cognitive control of multiple conflicts.
