The anger expression trait affects conflict monitor: a Go/No-go event-related potential study

The Anger-Out and Anger-In is the emotional expression of anger in two main ways. To explore the time course of inhibitory control in individuals with different anger expression trait, we recorded and analyzed event-related potential data relevant to the Go/No-go task. Although the No-go effect of P3 closely related to the actual inhibition of the motor system was similar between two groups, the No-go effect of N2 related to conflict monitoring was smaller in the Anger-In than that in the Anger-Out group. These data suggest the reduced early stage of inhibitory processes in Anger-In individuals, implicating the dysfunction of conflict monitoring and providing new electrophysiological evidence for the theory of anger expression.
