The present study used event-related potentials (ERPs) to investigate deficits in error-monitoring by college students with schizotypal traits. Scores on the Schizotypal Personality Questionnaire (SPQ) were used to categorize the participants into schizotypal-trait (n = 17) and normal control (n = 20) groups. The error-monitoring abilities of the participants were evaluated using the Simon task...

OBJECTIVE Prospective memory (PM) refers to the ability to remember to perform actions in the future. Schizophrenia spectrum disorders show impairments in PM but neural correlates of these impairments remain unclear. The present study aimed to examine brain activation during PM to identify impairments in individuals with schizotypal personality features. METHOD Nineteen participants with schi...

BACKGROUND While increasing evidence suggests that cannabis use may play a role in the development of schizophrenia in some young people, less is known about the strength and specificity of its relationship to latent schizophrenia liability, i.e., schizotypal personality disorder traits. AIMS Determine the predictive value of cannabis use during childhood and early adolescence on schizotypal ...

A link between maladaptive personality traits and an excessive use of massively multiplayer online roleplaying games (MMORPGs) has been documented. However, the role of schizotypal personality traits in MMORPG use is understudied. The aim of this study was to explore the potential links between schizotypal traits, motivations for playing MMORPGs, and symptoms of problematic MMORPG use. Eightyth...

OBJECTIVE This study examined whether the electrophysiological correlates of language processing found previously to be abnormal in schizophrenia are also abnormal in schizotypal individuals. The authors used the N400 component to evaluate language dysfunction in schizotypal individuals. METHOD Event-related potentials were recorded in 16 comparison subjects and 17 schizotypal individuals (wh...

BACKGROUND The clinical picture of schizotypal disorders is rarely comprehensively described. AIMS To describe psychopathological profiles of patients with ICD-10 schizotypal disorder. METHOD A total of 151 first-admitted patients (with affective and somatic disorders excluded) were given a comprehensive psychopathological evaluation, including the Bonn Scale for the Assessment of Basic Sym...

The author questions the assumption that family relationship should be given primacy as the validating criterion in establishing diagnostic items for the DSM-III definition of schizotypal personality disorder (SPD). The presenting characteristics of clinically defined patients may be quite different from those that best describe the nonpatient relatives of schizophrenic patients encountered in ...

The explicit and implicit memory of nonclinical individuals with schizotypal traits was investigated using event-related potentials. Explicit and implicit memory was measured with continuous recognition and categorization tasks, respectively. On the recognition task, the control group demonstrated a greater old/new effect in response to the old than to the new words during the 250-750 ms post-s...
