Effects of childhood emotional neglect on pain empathy: Evidence from event-related potentials

Abstract

Emotional neglect during childhood was associated with adverse long-term consequences for mental health and may impact neural responses by altering the trajectories of brain development. Pain empathy, a crucial social adaptive ability that recognizes and understands another person's pain, was found to be correlated with early developmental experiences. However, the impact of emotional neglect on neural responses related to pain empathy remains inadequately explored. Utilizing childhood trauma questionnaires and event-related potential (ERP), the electrical response of the brain to a specific stimulus, this study investigated the impact of emotional neglect experiences on pain empathy neural responses among 62 Chinese college students. The results of correlation analysis demonstrated a significant association between childhood emotional neglect scores and the empathic N2 responses (defined as pain minus non-pain conditions), representing the early emotional sharing process of pain empathy. The findings clarified the effects of specific forms of traumatic experiences on individuals' social functioning and laid the foundation for further exploring the impact of trauma on neural responses.
