Bottom Line: The prefrontal cortex is responsible for emotional conflict resolution, and this control mechanism is affected by the emotional valence of distracting stimuli.Importantly, these visual areas negatively coupled with the dorsolateral prefrontal cortex (DLPFC).This study thus provides a plausible mechanism of emotional conflict resolution that the rapid pathway for negative emotion processing efficiently triggers control mechanisms to preventively resolve emotional conflict.

ABSTRACT
The prefrontal cortex is responsible for emotional conflict resolution, and this control mechanism is affected by the emotional valence of distracting stimuli. In the present study, we investigated effects of negative and positive stimuli on emotional conflict control using a face-word Stroop task in combination with functional brain imaging. Emotional conflict was absent in the negative face context, in accordance with the activation observed in areas regarding emotional face processing (fusiform face area, middle temporal/occipital gyrus). Importantly, these visual areas negatively coupled with the dorsolateral prefrontal cortex (DLPFC). However, the significant emotional conflict was observed in the positive face context, this effect was accompanied by activation in areas associated with emotional face processing, and the default mode network (DMN), here, DLPFC mainly negatively coupled with DMN, rather than visual areas. These results suggested that the conflict control mechanism exerted differently between negative faces and positive faces, it implemented more efficiently in the negative face condition, whereas it is more devoted to inhibiting internal interference in the positive face condition. This study thus provides a plausible mechanism of emotional conflict resolution that the rapid pathway for negative emotion processing efficiently triggers control mechanisms to preventively resolve emotional conflict.

Mentions: A 2 (emotional congruency: congruent or incongruent)2 (the valence of emotional face: negative or positive) repeated-measures ANOVA was conducted on reaction time (RT) and accuracy. The statistical results for RT are displayed in Fig. 1A. There was a significant main effect of congruency (F1, 30 = 33.719, P < 0.001) (incongruent: 642 ms vs. congruent: 632 ms), a significant main effect of emotional face valence (F1,30 = 12.556, P = 0.001) (positive face: 640 ms vs. negative face: 634 ms), and a significant interaction effect (F1,30 = 10.719, P = 0.003). Follow-up analyses revealed that the conflict effect was absent for negative faces (F1,30 = 0.165, P = 0.687); in contrast, for positive faces, responses for congruent trials were faster than those for incongruent trials (F1,30 = 32.970, P < 0.001). In brief, the congruency effect was different between the contexts of positive and negative distracting faces.
