Behavioral and neural mechanisms underlying contextual processing in naturalistic short video viewing.

ABSTRACT: Contextual processing enables the brain to integrate environmental cues for adaptive emotional perception. It is crucial to understand how this ability operates in dynamic environments of short video viewing and how the brain supports it. In this study, we utilized behavioral and neuroimaging experiments to examine contextual processing during short video viewing. Compared with single-face clips, face-context-face sequences elicited coherent emotional perceptions of neutral faces from emotional contexts. A distributed brain network was involved in the top-down modulation of contextual processing. Temporoparietal junction (TPJ) and precuneus showed sustained engagement during context integration. Activity in TPJ and insula was associated with valence and arousal ratings, respectively. Under
