SOCIAL COGNITION IN SCHIZOPHRENIA
Associate Professor Melissa Green, PhD.
NHMRC Biomedical Career Development Fellow School of Psychiatry, Faculty of Medicine
University of New South Wales, Australia.
Themes for discussion:
1. Gestalt processing: holistic ‘integration’ of social and emotional information from various sources – problems with this may affect social/emotion perception as well as emotion regulation
2. Cross-modality integration of contextual cues: involves both cognitive and social cognitive information; implications for neural circuitry
3. Emotion regulation: aberrant physiology Vs. intact emotional experience
Integration of contextual cues in social cognition
