Schizophrenia and Cognitive Distortion

There is now evidence that cognitive distortions are seen in patients with schizophrenia  which are associated with the psychotic symptoms (Moritz, Ramdani, Klass, Andreou, Jungclaussen, Englisch, et al., 2014). Patients show often overconfidence in their errors and underconfidence in correct responses. Moritz et al. (2014) investigated if schizophrenia patients would show overconfidence on a perceptual judgment task. The patient group was compared with patients with obsessive compulsive disorder and healthy control participants. It was found that overconfidence to errors was not related to either memory or social cognition, rather it was related to perception.
