Electrophysiological insights into conceptual disorganization in schizophrenia.
Disorganized speech, or thought disorder, in schizophrenia may reflect abnormal processing of meaningful concepts. To examine whether schizophrenia involves abnormalities in how a meaningful context influences processing of concepts strongly, weakly, or not related to it, we used the N400, an event-related brain potential (ERP) index of semantic relatedness. ERPs were recorded from schizophreni...
متن کاملElectrophysiological insights into language processing in schizophrenia.
Deficits in language comprehension in schizophrenia were examined using event-related potentials (ERPs). Schizophrenic and healthy participants read sentences in which the first clause ended with a homograph, and the second clause started with a target word that was semantically related to the homograph's dominant meaning (e.g., 1. Diving was forbidden from the bridge because the river had rock...
متن کاملElectrophysiological insights into connectivity anomalies in schizophrenia: a systematic review
The pathophysiology of schizophrenia may fundamentally involve a disturbance in the interaction between neuronal groups that leads to impaired communication within and between brain areas. Such a “dysconnectivity syndrome” could underlie the pronounced cognitive deficits as well as the emergence of psychosis. Evidence for this hypothesis has mainly come from functional magnetic resonance imagin...
متن کاملElectrophysiological insights into language deficits
The human capacity for communication by means of a natural language is undoubtedly one of the most complex products of evolution. Most people seem to speak and listen effortlessly. And, yet, both psycholinguistic and neuropsychological research attest to the diverse set of representations that are accessed or constructed anew during ordinary language comprehension and production. Moreover, thes...
متن کاملConceptual disorganization weakens links in cognitive pathways: Disentangling neurocognition, social cognition, and metacognition in schizophrenia.
Disentangling links between neurocognition, social cognition, and metacognition offers the potential to improve interventions for these cognitive processes. Disorganized symptoms have shown promise for explaining the limiting relationship that neurocognition holds with both social cognition and metacognition. In this study, primary aims included: 1) testing whether conceptual disorganization, a...
