Linguistic complexity serves as an important measure of second language (L2) writing development. Complexity indices, however, rarely feature in the studies of learner languages other than English. Additionally, L2 writing studies have been criticized for the lack of consistency in defining proficiency. The current study addresses these gaps by…

This study examined how well second language (L2) recall and recognition vocabulary tests correlated with a reading test, how well each vocabulary test discriminated between reading proficiency levels, and how accurate each test was in predicting reading proficiency when compared with corpus studies. A total of 116 college-level learners of…

One of the central considerations in the validity argument for the TOEFL iBT is the relationship between the language on the exam and the language required for university courses. Corpus linguistics has recently been shown to be an effective way to explore this relationship, which can also be considered as an aspect of authenticity. Applying…

This study investigates relations between second language (L2) lexical input and output in terms of word information properties (i.e., lexical salience; Ellis, 2006a). The data for this study come from a longitudinal corpus of naturalistic spoken data between L2 learners and first language (L1) interlocutors collected over a year's time. The…

This study suggests that Intermediate High and Advanced speakers produce aspectually valid constructions in Oral Proficiency Interviews (OPIs) in large part because they are doing more than assigning aspect to lexical categories (Lexical aspect hypothesis), but because they are assigning lexicalized meaning to discrete verbs, for example…

This study was an examination of the relationship of lexical richness to the quality of English as a second language (ESL) learners' oral narratives. A computational system was designed to automate the measurement of 3 dimensions of lexical richness, that is, lexical density, sophistication, and variation, using 25 different metrics proposed in…

This study explores the development of multiple dimensions of linguistic complexity in the writing of beginning learners of German both as a group and as individuals. The data come from an annotated, longitudinal learner corpus. The development of lexicogrammatical complexity is explored at 2 intersections: (a) between cross-sectional trendlines…
