One of the major issues in SLA is developing language tests that could produce good measures of implicit knowledge. This study examines the validity of an English Elicited Imitation (EI) test as a measure of L2 implicit grammatical knowledge. Forty freshman university students in Turkey took a set of language tests: an EI test, two storytelling tasks, a picture description task, IELTS listening sample tests and a speaking test. Four English morphemes were chosen as the target structures: third person ‘-s’, plural ‘-s’, simple past ‘-ed’, and comparative ‘-er’. Results from a principal component analysis showed that all measures were loaded on a single component labelled as implicit knowledge. Significant correlations with varying magnitude were also recorded between learners’ EI scores for the target structures and their scores on other time-pressured measures: r = .63, r = .63, r = .65 and r = .43, for third person ‘-s’, simple past ‘-ed’, plural ‘-s’ and comparative ‘-er’, respectively. These findings suggest that the likelihood of EI measuring L2 implicit grammatical knowledge may vary depending on language structures.

引诱模仿的结构敏感性作为隐含语法知识的量度

SLA的主要问题之一是开发语言测试，以产生良好的内隐知识度量。这项研究检验了英语模仿考试（EI）作为衡量L2隐含语法知识的一种方法的有效性。土耳其的40名大一新生参加了一系列语言测试：一项EI测试，两项讲故事任务，一张图片描述任务，雅思听力样本测试和一项口语测试。选择了四个英语语素作为目标结构：第三人称“ -s”，复数“ -s”，简单过去的“ -ed”和比较性“ -er”。主成分分析的结果表明，所有度量均加载到标记为隐性知识的单个成分上。还记录了学习者的目标结构的EI得分与他们在其他时间压力测量的得分之间的显着相关性，即第三人称r = .63，r = .63，r = .65和r = .43。 “ -s”，简单过去的“ -ed”，复数“ -s”和比较性“ -er”。这些发现表明，EI评估L2隐式语法知识的可能性可能会因语言结构而异。
