N400 and automatic semantic processing abnormalities in patients with schizophrenia.
BACKGROUND One factor hypothesized to underlie thinking disturbance in patients with schizophrenia is abnormal or disinhibited automatic spreading activation of semantic networks, which can be assessed using the N400 event-related potential. N400 is a negative-going component elicited at about 400 milliseconds following semantic stimuli that are not primed by the preceding context. Semantic pri...
متن کاملThe Relationships of Sensory Processing Sensitivity and Information Processing Styles to Clinical Symptoms in Drug-Dependent Individuals
Objective: The aim of this study was to examine the roles of sensory processing sensitivity and information processing styles in predicting clinical symptoms in drug-dependent individuals. Method: The current study was correlational-descriptive. The statistical population included all drug-dependent individuals referred to addiction treatment centers in Tabriz. Among them, 290 people were selec...
متن کاملInformation-processing deficits across childhood- and adult-onset schizophrenia.
Event-related potentials were recorded for childhood- and adult-onset schizophrenia subjects performing the span of apprehension (Span) task, which is sensitive to vulnerability factors in schizophrenia. Subjects responded to the onset of the Span arrays in a reaction time condition and then responded differentially to the presence of one of two target letters in the Span condition. While neith...
متن کاملAutomatic semantic priming abnormalities in schizophrenia.
Abnormal activation of semantic networks characterizes schizophrenia and can be studied using the N400 event-related potential (ERP). N400 is elicited by words that are not primed by the preceding context and provides a direct measure of the neural mechanisms underlying semantic priming. Semantic priming refers to facilitated semantic processing gained through pre-exposure to semantic context, ...
متن کاملPrevalence of diabetes, metabolic syndrome and metabolic abnormalities in schizophrenia over the course of the illness: a cross-sectional study
BACKGROUND Patients with schizophrenia are at high risk of developing metabolic abnormalities. METHOD A prospective study focusing on metabolic disturbances in patients with schizophrenia, including an oral glucose tolerance test, is currently ongoing at our University Hospital and affiliate services. The prevalence of metabolic abnormalities at baseline was assessed in a cohort of 415 patien...
