Elicited imitation (EI) tasks are a practical tool for measuring second language (L2) knowledge and skills. In this study, we implemented a web-based EI task that measures English morphosyntactic knowledge and compared its measurement properties to a traditional laboratory-based EI. A cohort of 149 L2 English learners engaged in the web-based EI task, and 151 participants completed a traditional lab-based EI counterpart. Correlation analyses revealed a significant, comparable relationship between English proficiency and the two EI versions, with the ungrammatical items showing less consistency that neither improved nor harmed the overall EI effectiveness. Factor analyses corroborated the validity of web-programmed EI, with both EI versions relating similarly to time-pressured, implicit knowledge and untimed, explicit knowledge measures. Our results suggest the potential for utilizing web-based EI to substitute lab-based tasks, enabling larger-scale, more diverse sampling. We end with implications for future web-based EI task users and include a coding guideline for customized web-based EI use.

基于实验室和网络的诱发模仿的比较:来自显性隐含 L2 语法知识和 L2 熟练程度的见解



诱发模仿 (EI) 任务是衡量第二语言 (L2) 知识和技能的实用工具。在这项研究中,我们实施了一项基于 Web 的 EI 任务,该任务测量英语形态句法知识,并将其测量特性与传统的基于实验室的 EI 进行比较。一组 149 名 L2 英语学习者参与了基于网络的 EI 任务,151 名参与者完成了传统的基于实验室的 EI 对应任务。相关性分析显示,英语熟练度与两个 EI 版本之间存在显著的、可比的关系,非语法项目显示出较差的一致性,既没有提高也没有损害整体 EI 有效性。因子分析证实了网络编程 EI 的有效性,两种 EI 版本都与时间紧迫的内隐知识和不定时的外显知识测量相似。我们的结果表明,利用基于 Web 的 EI 来替代基于实验室的任务,实现更大规模、更多样化的采样的潜力。最后,我们总结了对未来基于 Web 的 EI 任务用户的影响,并包括了自定义基于 Web 的 EI 使用的编码指南。
