Direct and averted gaze modulate the event-related brain responses to social exclusion signals.

ABSTRACT: Social exclusion is a negative experience in social interaction which can be modulated by the perceived eye gaze. In our Cyberball study, we asked how gaze direction - direct versus averted - affects the processing of social exclusion by using electroencephalogram (EEG) methods. Participants encountered neutral gazes in the inclusion phase (Block1) and then either direct or averted gazes during the exclusion phase (Block2). We measured self-reports on Need-Threat Questionnaires (belonging, control, meaningful existence, self-esteem) and negative mood, along with event-related potentials (ERPs), specifically the P3 component (P300) - an indicator of expectation violation. Findings demonstrated that the P3 amplitude showed differential changes between gaze conditions during the transition fr
