Time-resolved multivariate EEG decoding in immersive VR reliably distinguishes neutral, happy, angry, and surprised facial expressions, and stereoscopic depth cues add a distinct decodable neural signature.
- Why it matters: Most face-processing EEG work uses two-dimensional displays, leaving uncertainty about whether binocular depth information changes neural representations of facial expressions.
- What they did: Thirty-four participants viewed computer-generated frontal faces in monoscopic versus stereoscopic VR while EEG and eye tracking were recorded; time-resolved multivariate decoding tested expression and depth representations.
- The result: Expression decoding stayed robust across depth conditions, implying invariant neural representation of behaviorally distinguishable expressions under controlled frontal viewing, while depth signals were not present in gaze patterns.
