- Abstract: The underlying nature of delusions remains unclear despite their importance in psychopathology. Here we present a review of the neurocognitive model of delusions from a cognitive neuroscience viewpoint. There have been numerous reports on cognitive impairments in delusional patients, such as in their reasoning, attention, metacognition, and attribution biases. These findings have been incorporated into several cognitive models that aim to explain the formation, maintenance, and content of delusion. Although delusions are commonly conceptualized as beliefs, not all models make reference to models of normal belief formation. This review focused on two-factor theory models that make a distinction between factors that explain the content of delusions and those that explain their presence. This cognitive theory that includes the 'pragmatic pathology' of delusions can address both the phenomenology and treatment of delusion-related distress.
