Abstract

Growing evidence suggests that positive mood has a profound influence on cognitive control. Yet the neural underpinnings of positive mood regulations on conflict resolution remain unclear. Event-related potentials (ERPs) offer a direct, temporally precise, multidimensional view of brain activity, and thus are well suited to examine how processing dynamics are modulated in response to a positive mood. In this study, we investigated the interactions of positive mood and cognitive control by using the numerical Stroop task in which numerical value and physical size were varied under task-relevant and -irrelevant conditions. Mood was induced by emojis, symbols that are considered a new medium for effective emotion sharing when using computer-mediated communication. The ERP results showed that congruent trials had a less negative N200 response than neutral trials (a facilitation effect) under both neutral and positive moods, and the facilitation effect was larger under positive mood. Incongruent trials elicited a larger early N450 response than neutral trials (an interference effect) only in positive mood. On the late positive component (LPC), both facilitation and interference effects were still observed in positive mood. In contrast, only facilitation effect was observed in neutral mood at LPC. Additionally, the LPC latency was later and the accuracy was lower under positive mood. Overall, the findings imply that positive mood broadened the attention and thereby increased the processing of task-irrelevant information. These results are compatible with the broaden-and-build theory, and demonstrate that positive mood impaired conflict resolution.
