Abstract

Abstract

En 中文
• Metacognition can be assessed both directly and indirectly using clinical, cognitive insight and cognitive bias measures. • Hallucinations and delusions may be conceptualized as failures of metacognitive processes. • Poorer metacognitive abilities are associated with greater positive symptom severity. • Metacognitive training is associated with reductions in positive symptoms, thus improvements in quality of life. • A deeper understanding of the epistemological relationship between positive symptoms and altered metacognition, whether as a cause or a consequence, may inform more effective treatment and preventive interventions for psychotic disorders.
