【摘要】 本文利用词意分类作业对19例精神分裂症病人的事件相关电位进行对照研究。结果表明,词意分类作业中,虽然无关刺激在精神分裂症病人中诱发 ERPs 在300—600ms 内负性活动也显著高于相关刺激诱发的 ERPs,但精神分裂症组相关刺激诱发的 ERPs 在以上时间窗内的负性活动显著高于正常对照组。这种差异提示精神分裂症病人的语言信息处理过程可能存在某种程度的障碍。更多还原

【Abstract】 A controlled study of ERP in semantic categorization task was carried out on 19schizophrenics.On contrast to the ERP to related pictorial stimuli,the ERP to unrelated pictorial stim-uli was significantly more negative in the latencies ranging from 300 to 600 ms.These cases occurredin both the two groups.But the ERPs to related stimuli in schizophrenia were more negative in theabove time window than those in normal controls.These results suggested there were differences in se-mantic information processing between the two groups.更多还原
