1. Gestalt processing: holistic โintegrationโ of social and emotional
information from various sources โ problems with this may affect
social/emotion perception as well as emotion regulation
2. Cross-modality integration of contextual cues: involves both cognitive and

3. Emotion regulation: aberrant physiology Vs. intact emotional experience
