Abstract

In processing their two languages, bilinguals have to selectively attend to the target language and reduce interference from the non-target language. This experience may have specific cognitive consequences on Executive Functions (EF) through bilingual language processing. Some studies found cognitive consequences in executive functioning skills. However, other studies did not replicate these findings or found a bilingual disadvantage. The aim of this study was to test for the cognitive consequences of bilingualism in EF among a large number of young adults using a latent variable approach, to rule out non-EF task differences as an explanation for inconsistency across studies. Also, we were interested in testing the EF structure using the Confirmatory Factor Analysis (CFA) approach. The results did not support a cognitive consequence of bilingualism and also the EF structure was the same for both groups. We discuss other possible variables that might contribute to the mixed results across studies.

利用确证因子分析分析单语和双语成人的执行功能结构
在处理两种语言时,双语者必须有选择地注意目标语言,减少非目标语言的干扰。这种经历可能会通过双语语言处理对执行功能(EF)产生特定的认知后果。一些研究发现了对执行功能技能的认知影响。然而,其他研究并没有重复这些发现,或者发现了双语的劣势。本研究的目的是采用潜在变量法,在大量年轻成人中测试双语对执行功能的认知影响,以排除非执行功能任务差异对不同研究不一致的解释。此外,我们还有兴趣使用确证因子分析(CFA)方法来测试 EF 结构。结果不支持双语的认知结果,而且两组的 EF 结构相同。我们还讨论了可能导致不同研究结果参差不齐的其他变量。
