Misattribution of external speech in patients with hallucinations and delusions.
BACKGROUND One of the main cognitive models of positive symptoms in schizophrenia proposes that they arise through impaired self-monitoring.

We examined whether patients with hallucinations and delusions would demonstrate an...
متن کاملImagine that: elevated sensory strength of mental imagery in individuals with Parkinson's disease and visual hallucinations.
Visual hallucinations occur when our conscious experience does not accurately reflect external reality.

متن کاملImpaired Self-Monitoring of Inner Speech in Schizophrenia Patients with Verbal Hallucinations and in Non-clinical Individuals Prone to Hallucinations
BACKGROUND Previous research has shown that various memory errors reflecting failure in the self-monitoring of speech were associated with auditory/verbal hallucinations in schizophrenia patients and with proneness to hallucinations in non-clinical individuals. METHOD We administered to 57 schizophrenia patients and 60 healthy participants a verbal memory task involving free recall and recogn...

The electroencephalographic and clinical findings in this case suggest that cortical and subcortical structures of the right hemisphere may play a role in mediating the expression of language...
