Int J Appl Linguist. 2018;1–15. wileyon This paper examines the development and variation of syntactic complexity in the speech of 66 L2 learners over three academic semesters in an intensive English program. This investigation tracked development using hierarchical linear modeling with three commonly‐used, recommended measures of productive complexity (i.e., length of AS‐unit, clause length, subordination) and three exploratory measures of structural complexity (i.e., syntactic variety, weighted complexity scores, frequency of nonfinite clauses) to capture different aspects of syntactic complexity. All measures showed growth over time, suggesting that learners are not forced to prioritize certain aspects of the construct at the expense of others (i.e., no trade‐off effects) across development. The unexplained significant variation found in these data differed among the measures reinforcing notions of multidimensionality of linguistic complexity.

寻找变化：评估 ESL 语音中句法复杂性的发展

Int J Appl 语言学家。2018 年；1-15。wileyon 本文研究了 66 名 L2 学习者在三个学期的英语强化课程中的语音中句法复杂性的发展和变化。该调查使用分层线性建模跟踪开发，其中包含三个常用的生产复杂性推荐度量（即 AS 单元的长度、子句长度、从属）和三个结构复杂性的探索性度量（即句法多样性、加权复杂性分数、非限定从句的频率）来捕捉句法复杂性的不同方面。所有措施都显示出随着时间的推移而增长，这表明学习者不会被迫在整个发展过程中以牺牲其他方面（即没有权衡效应）为代价来优先考虑结构的某些方面。
