False memories in schizophrenia? An imagination inflation study.
Summary of "False memories in schizophrenia? An imagination inflation study."
Data showing how schizophrenia patients tend to be more susceptible to false memories have been rather mixed and, as far as we know, no studies have investigated whether patients with a schizophrenia spectrum disorder are particularly prone to imagination inflation effects, that is, whether repeatedly imagining an action increases the likelihood of remembering the action as having been performed. In this study, a group of patients with psychosis and a group of normal controls were asked to perform or to imagine performing simple action statements one or four times in a single study session. In a test session that occurred 24 h later, participants were instructed to discriminate whether the action statement had been carried out, imagined or whether it was new (a source monitoring task). The primary finding was that patients were more susceptible to source-monitoring errors than controls, especially in terms of considering an imagined action as having been performed. However, both groups showed comparable levels of imagination inflation effects. Results add evidence to the hypothesis that the nature of patients' false memories may be particularly linked to poor use of source-monitoring processes.

Medical and Biotech [MESH] Definitions
A chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.
A type of schizophrenia characterized by abnormality of motor behavior which may involve particular forms of stupor, rigidity, excitement or inappropriate posture.
An obsolete concept, historically used for childhood mental disorders thought to be a form of schizophrenia.

Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.
