二语熟练度及语言使用特征对双语者抑制控制能力的影响

本文考察双语者二语熟练程度及不同语言使用特征对其抑制控制能力影响的差异。根据二语的熟练程度将被试分为熟练双语者组和不熟练双语者组,在熟练组和不熟练组中根据不同的语言使用特征划分为以口语为主和以阅读为主的两个被试组。所有被试都参与Stroop任务、Simon任务和Flanker任务。结果发现:熟练度高的双语者在三种任务中均表现出了优势反应。说明二语熟练程度对双语者的抑制控制能力有着促进作用;在不同语言使用特征组中,两组被试在simon任务与stroop任务中表现无显著差异,但表现出明显的CA效应。表明二语熟练度影响双语者的抑制控制能力;语言使用特征的不同对双语者的抑制控制能力无显著影响。

Effects of Second Language Proficiency and Language Use Characteristics on Inhibitory Control Ability of Bilinguals

To investigate the effects of second bilinguals language proficiency and language use characteristics on their inhibition and control abilities.According to the proficiency level of the second language,the subjects were divided into the proficient bilingual group and the unskilled bilingual group.In the proficient group and the unskilled group,according to the characteristics of different language use,the subjects were divided into two groups,which were mainly spoken and mainly read.All subjects participated in the Stroop task,Simon task and Flanker task.The results showed that the highly skilled bilinguals showed dominant responses in all three tasks.It indicates that the proficiency of second language can promote the inhibition and control ability of bilinguals.In different language use feature groups,there was no significant difference between the two groups in The Simon task and the Stroop task,but there was significant CA effect.It shows that the second language proficiency affects the inhibition and control ability of bilinguals.The differences of language use characteristics have no significant effect on the inhibitory control ability of bilinguals.
