词汇的复杂性是写作能力的重要组成部分。新的词汇指标涉及范围，n-gram频率，心理语言学词汇信息，学术语言，一词多义和上位词产生了新的见解词汇复杂性的结构及其与第二语言（L2）的习得和写作的关系。例如，最近的研究表明，在二语习得和二语写作和口语水平的背景下，范围和二元语法指数是比频率更强的词汇复杂性指标。本研究探讨了这些新开发的词汇成熟度指标与独立写作和基于源代码写作的整体成绩之间的关系。结果表明，范围和二元语法是独立任务中文章质量的重要预测因子，但词汇复杂度指数在基于源代码的任务中并不是文章质量的强预测因子。结果还表明，基于源的任务的反应往往包括更复杂的词汇项目比独立的任务的反应。对第二语言写作评估和教学的影响进行了讨论。(C)2016 Elsevier Inc.

Lexical sophistication is an important component of writing proficiency. New lexical indices related to range, n-gram frequency, psycholinguistic word information, academic language, polysemy, and hypernymy have yielded new insights into the construct of lexical sophistication and its relationship with second language (L2) acquisition and writing. For example, recent studies have suggested that range and bigram indices are stronger indicators of lexical sophistication than frequency in the context of L2 acquisition and L2 writing and speaking proficiency. This study explores the relationship between these newly developed indices of lexical sophistication and holistic scores of writing proficiency in both independent and source-based writing tasks. The results suggest that range and bigrams are important predictors of essay quality in independent tasks, but that lexical sophistication indices are not strong predictors of essay quality in source-based tasks. The results also indicate that responses to source-based tasks tend to include more sophisticated lexical items than responses to independent tasks. Implications for second language writing assessment and pedagogy are discussed. (C) 2016 Elsevier Inc. All rights reserved.
