Negative-Emotion-Neurophysiogical-Sociability

From Affective, Neuroscience, and Decision-making Lab

Highlights

• We combined virtual reality & simultaneous EEG-ECG recording to probe the neurophysiological responses of nehative emotions
• We first found a common neurophysiological response pattern of negative emotions under virtual reality
• Furthermore, individual variation of sociability could be captured by neurophysiological responses
• Virtual reality has promising utility in naturalistic neuroimaging and socio-affective research

Description

• This repo mainly contains scripts for processing multimodal neurophysiological data from the VR emotion project.
• Data modality: EEG (Brain Porduct 64 ch, montage see BP_Montage), ECG (BIOPAC 3 leads)
• Paradigm: naturalistic viewing of negative emotinal videos under virtual reality (Unity + Steam VR)
• VR googles: VIVE Pro EYE (HTC)
• Main analysis method: Intersubject similarity analysis (ISC) & Intersubject representational similarity analysis (IS-RSA)
