Reasoning in psychosis: risky but not necessarily hasty.

Introduction: A liberal acceptance (LA) threshold for hypotheses has been put forward to explain the well-replicated "jumping to conclusions" (JTC) bias in psychosis, particularly in patients with paranoid symptoms. According to this account, schizophrenia patients rest their decisions on lower subjective probability estimates. The initial formulation of the LA account also predicts an absence of the JTC bias under high task ambiguity (i.

Complementary group Metacognitive Training (MCT) reduces delusional ideation in schizophrenia.

Background: Symptom reduction under antipsychotic agents is incomplete for most schizophrenia patients. In order to enhance outcome, cognitive approaches are increasingly adopted as add-on interventions. The present study aimed to determine the efficacy of group Metacognitive Training (MCT), which targets cognitive biases putatively involved in the pathogenesis of delusions.

Predictors of performance improvements within a cognitive remediation program for schizophrenia.

Cognitive impairment is regarded a core feature of schizophrenia and is associated with low psychosocial functioning. There is rich evidence that cognitive remediation can improve cognitive functions in patients with schizophrenia. However, little is known about what predicts individual remediation success.

"Don't give me that look" - overconfidence in false mental state perception in schizophrenia.

Dysfunctions in social cognition are implicated in the pathogenesis of schizophrenia and have been extensively replicated over the years. For memory research, the administration of cognitive tasks with metacognitive aspects like confidence ratings has deepened our insight into how impairments contribute to symptoms of the disorder. A total of 76 patients with schizophrenia or schizoaffective disorder and a sample of 30 healthy participants were tested with the Reading the Mind in the Eyes test (Eyes-test).
