摘要: article i nfo Objective: This study aimed to examine semantic processing features in individuals with and without schizotypal personality disorder (SPD) features. Methods: An implicit task was used the automatic spreading activation process which is relatively free from influence of attention. explicit controlled requires high involvement Individuals stable SPD (n=17) were those who scored higher than 36 on questionnaire (SPQ) at two time points. unstable (n=15) defined as participants baseline point but lower second point. Their per- formances tasks then compared 17 (scoring below both points). Event-related potentials (ERP) recorded when performing tasks. Results: Behavioral data, early ERP components N400s analyzed each experiment. No between-group difference observed task. In task, dif- ferences involved only N400 component. When group features, partici- pants showed enhanced effects (difference wave), while there no between groups Moreover, larger found be due less negative amplitudes related target words. Conclusion: These findings suggest that impaired context-related stimuli. The inhibition function contextually unrelated materials appeared intact.
