Executive functions as predictors of Japanese freshman undergraduates' global and four skills English proficiency

这组间比较横断面研究旨在阐明执行功能（EFs）在高中毕业生进入大学的第二语言水平达到的作用。本研究计划对200名大一学生进行测试，以测量他们的转换、更新和抑制能力，并考察他们与标准化的整体和四项技能的L2水平测量成绩之间的关系。该研究1）将当前的研究扩展到对多个EF进行更系统的检查; 2）检查EF在四种技能熟练度中的作用;以及，3）从广泛的学术成就中抽取数据。2019财年为2020财年试点：通过2020年5月和6月的三个阶段（基线，EF测试和L2测量）收集数据。元认知测量也加入了这项研究。2021财政年度的测试使用EPrimeGo（EFs）和微软平台在线进行。由于最终用户芯片组兼容性问题，N=32名参与者放弃了研究。这一数据集转录和分析进行。CFA还对以前的元认知数据进行了分析，得出了一个13项元认知双因素模型，与数据非常吻合（2022/3发布）。在2022财年，在RA的帮助下，于4月至7月进行了数据收集，结果有N=571名参与者，其中n=79名完成了EF和L2生产任务。已转录和分析数据，目前正在编写文件供提交。

This between-groups comparison cross-sectional research seeks to elucidate the role of executive functions (EFs) in the attained L2 proficiency levels of high school graduates entering university. The research plan proposed testing of 200 first year undergraduates to measure EF capacities of switching, updating and inhibition, and examine their relationships to scores on standardized global and four-skills L2 proficiency measures. The study 1) extends current research to a more systematic examination of multiple EFs; 2) examines the role of EFs in four skills proficiency; and, 3) samples data from a wide range of academic achievement.FY2019 for FY2020 pilot: data collection in three phases (baselines, EF tests, and L2 measures) through May and June of 2020. Metacognition measure also added to the study. Face-to-face testing was not possible due to the pandemic.FY2021 testing moved online using EPrime Go (EFs) and Microsoft platforms. Due to end-user chipset compatibility issues study abandoned at N=32 participants. This dataset transcribed and analyses carried out. CFA also carried out on previous metacognition data resulting in a 13-item two-factor model of metacognition with excellent fit to the data (published 2022/3). Further CFAs on FY2020 and FY2021 data indicate a stable model and paper currently being prepared for submission.In FY2022, data collection was carried out April-July with help of RAs, resulting in a N=571 participants of which n=79 completed EF and L2 production tasks. Data transcribed and analysed and paper currently being prepared for submission.
