Individuals with schizophrenia display behaviour inconsistent with learned social impressions during a gambling task.

Many studies of social perception and judgement have required individuals to make evaluations of social parameters based on static presentations of social stimuli. In the current study, we assessed whether individuals with a schizophrenia spectrum disorder and community controls differed in their judgements of others based on a series of computerized encounters designed to simulate impression formation over time. Twenty-eight community controls and 29 individuals with a schizophrenia spectrum disorder completed 25 gambling interactions with three different computer partners.

Course and symptom and functional correlates of passivity symptoms in schizophrenia: an 18-year multi-follow-up longitudinal study.

Background: Change in the experience of oneself may lay the groundwork for the development of additional hallucinations and delusions in individuals with schizophrenia. However, to date, the course and symptom and functioning correlates of passivity symptoms (cf. thought insertion, thought withdrawal) have not been measured consistently over long periods of time.

Altered amygdala-prefrontal connectivity during emotion perception in schizophrenia.

Individuals with schizophrenia evidence impaired emotional functioning. Abnormal amygdala activity has been identified as an etiological factor underlying affective impairment in this population, but the exact nature remains unclear. The current study utilized psychophysiological interaction analyses to examine functional connectivity between the amygdala and medial prefrontal cortex (mPFC) during an emotion perception task.

Schizophrenia symptom and functional correlates of anterior cingulate cortex activation to emotion stimuli: An fMRI investigation.

Schizophrenia is a chronic mental illness characterized by distinct positive and negative symptoms and functional impairment. The anterior cingulate cortex (ACC) is a region of the brain's limbic system that is hypoactive during emotion processing in schizophrenia. Recent evidence suggests the hypoactive ACC in schizophrenia is due to negative (and not positive) symptoms.

Associations between trait anhedonia and emotional memory deficits in females with schizophrenia versus major depression.

Individuals with schizophrenia (SZ) and individuals with major depressive disorder (MDD) demonstrate impaired emotional memory and decreased enjoyment of pleasant experiences (e.g., anhedonia).
