The research compares the perception of facial expressions (FE) of emotions in controls and schizophrenic patients. Three studies are presented. The first and the second study use a new morphing technique to test whether Categorical Perception (CP) exists for static displays of FE. The joint analysis of an identification (first study) and a discrimination task using morphing transitions between Neuter-Happiness and Neuter-Anger expressions demonstrate the presence of CP only for Anger in controls. CP does not occur in first-episode schizophrenia patients. The third study tests the identification of the six basic emotions in dynamic conditions. The results of a recognition task of FE from video clips showing the transformation between a neutral face and an emotional face demonstrates that schizophrenia patients need more time and a more intense facial activity than controls to detect basic emotions. It also shows that patients show selective impairments in the identification of Fear and Disgust.
