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

这一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时达到的第二语言熟练水平中的作用。本研究计划对200名一年级本科生进行测试，以测量英语的转换、更新和抑制能力，并研究它们与标准化全球和四技能外语熟练程度测试分数的关系。该研究1)将目前的研究扩展到对多个EFs进行更系统的检查；2)考察ef在四项技能熟练程度中的作用；3)从广泛的学术成就中取样数据。2020财年试点的2019财年：到2020年5月和6月分三个阶段（基线、EF测试和L2措施）收集数据。元认知测量也加入到研究中。由于大流行，无法进行面对面检测。2021财年的测试将使用EPrime Go （EFs）和微软平台进行在线测试。由于终端用户芯片组兼容性问题，研究在N=32参与者时被放弃。对该数据集进行转录和分析。CFA还对以前的元认知数据进行了分析，得到了一个13项的元认知双因素模型，与数据拟合良好（发表于2022/3）。关于2020财年和2021财年数据的进一步CFAs表明，目前正在准备提交一个稳定的模型和文件。在2022财年，在RAs的帮助下，数据收集于4月至7月进行，结果有N=571名参与者，其中N= 79名完成了EF和L2生产任务。对数据进行转录和分析，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.
