Behavioral (reaction time) and prefrontal cortex response revealed differences in grief vs. sadness perception.

ABSTRACT: Research on basic emotions has expanded beyond the traditional six categories, identifying over 20 distinct emotional states. However, differentiating some emotions remained challenging due to partially overlapping facial expressions. Grief and sadness are two such emotions that are difficult to distinguish. This study investigated the behavioral and neural mechanisms of grief perception in the prefrontal cortex (PFC), comparing it with sadness. Participants categorized and rated emotional facial images in grief and sadness conditions on valence, arousal, and dominance scales. While participants perceiving emotional facial images prefrontal cortex (PFC) hemodynamic activities were measured using functional near-infrared spectroscopy (fNIRS). Explicit behavioral responses showed no signific
