We investigated the time course and processes in the recognition of facial expressions in peripheral vision (10.5°). Happy faces were categorized more accurately and faster than angry, fearful, sad, and neutral faces. Consistently, the N1 (90 to 130ms post-stimulus) and N2pc (200-300ms) ERP (event-related-potentials) components were more negative, and the SPWs (slow positive waves; 700-800ms) were smaller, for happy than for non-happy faces. Computational modeling revealed that the smiling… CONTINUE READING
