| 摘 要： | 目的:通过事件相关电位技术和Eriksen Flanker任务的结合,探讨青少年吸烟者的认知控制能力是否存在异常。方法:采用被试者包括吸烟者19名(n=19),以及年龄、性别、受教育年限等与之相匹配的健康非吸烟者19名(n=19),比较两组的错误相关成分错误正波及其行为学任务表现。结果:与健康非吸烟者相比,吸烟组的错误数明显增加(F=5.133,P=0.030)。同时,青少年吸烟者的错误正波Pe的波幅有明显降低(P<0.001)。结论:青少年吸烟者存在错误处理缺陷,错误处理能力的降低可能与吸烟有关。

| Abstract: | Objective To investigate whether the adolescent smokers'ability of cognitive controlis normal through the combination of event-related potential(ERP)technology and Eriksen Flanker task.Methods The samples included 19 smokers(n=19),and 19 healthy non-smokers(n=19)well matched the former in age,gender and education years.The error-related component,error positivity(Pe)and behavioral task performance of the two groups were compared.Results Compared with the healthy non-smokers,the number of errors inthe smoking group increased significantly(F=5.133,P=0.030).At the same time,the Pe amplitude of adolescent smokers was significantly reduced(P<0.001).Conclusion Adolescent smokers have defects in error processing,and their reduction of error processing ability may be related to smoking. |
