How do fundamental emotion beliefs affect the rapid emotional processing? An ERP study

Abstract

Beliefs about whether emotions are good or bad, controllable or uncontrollable are two fundamental emotion beliefs. Studies have confirmed the link between the two beliefs and emotional responses, but how emotion beliefs affect the process from emotional stimulus perception to emotion generation and automatic regulation is unclear. Answering this question helps to understand the role of emotion beliefs in emotional dysfunction and dysregulation and can provide a basis for effective emotion regulation. Therefore, the current study used event-related potential (ERP) measures to examine the time course and neural mechanisms by which emotional beliefs influence the processing of emotional pictures. One hundred participants were divided into four groups (25 per group) according to controllable or uncontrollable beliefs about emotions and good or bad beliefs about negative emotions, and viewed emotional negative and neutral pictures. Results showed that P2 was more positive in participants with emotion controllable vs. uncontrollable belief. The early posterior negativity (EPN) was more negative for unpleasant than neutral images in participants with emotion good and controllable beliefs as well as with bad and uncontrollable beliefs. On late positive potential (LPP), middle LPP (500-1000ms) was more positive in emotion good vs. bad belief holders and the late LPP (1000-2000 ms) was more positive for negative than neutral images in emotion uncontrollable belief holders. The findings suggest that fundamental emotion beliefs can affect individuals' early attention and late meaning evaluation towards unpleasant stimuli. Furthermore, they provide insight into altered beliefs about emotion in people with emotion dysfunction or dysregulation.
