What impact does minimal exposure to Welsh have on Executive Functions? Evidence from primary school children.

摘要：该项目研究了最小的额外语言暴露对儿童非语言认知方面的影响。具体来说，该项目考察了在学校接触第二语言（威尔士语）最少的英语儿童与单语儿童的认知控制（执行功能）发展情况。该研究旨在解决有关双语好处的核心问题，特别是与增强执行功能有关的问题。预计产出将为当前的理论和方法争议提供信息。

Summary:The project examines the effect of minimal additional language exposure on non-linguistic aspects of cognition in children. Specifically, the project examines the development of cognitive control (executive functions) in English speaking children with minimal exposure to a second language (Welsh) in school, in comparison with their monolingual peers. The study aims to address central questions in the field regarding benefits of bilingualism, specifically in relation to enhancement of executive functions. Outputs are expected to inform current theoretical and methodological controversies.
