Lexical frequency benchmarks have been extensively used to investigate second language (L2) lexical sophistication, especially in language assessment studies. However, indices based on semantic co-occurrence, which may be a better representation of the experience language users have with lexical items, have not been sufficiently tested as…

This study examined the semantic features of the simulated mini-lectures in the listening sections of the International English Language Testing System (IELTS) and the Test of English as a Foreign Language (TOEFL) based on automatized semantic analysis to explore the content validity of the two tests. Two study corpora were utilized, the IELTS…

Nonverbal behavior can impact language proficiency scores in speaking tests, but there is little empirical information of the size or consistency of its effects or whether language proficiency may be a moderating variable. In this study, 100 novice raters watched and scored 30 recordings of test takers taking an international, high stakes…

Integrated speaking tasks requiring test takers to read and/or listen to stimulus texts and to incorporate their content into oral performances are now used in large-scale, high-stakes tests, including the TOEFL iBT. These tasks require test takers to identify, select, and combine relevant source text information to recognize key relationships…

This study aims to investigate patterns of variation in the interplay of L2 language ability and general reading comprehension skills in L2 reading, by comparing item-level effects of test-takers' results on L1 and L2 reading comprehension tests. The material comes from more than 500,000 people tested on L1 (Swedish) and L2 (English) in the…

While the research literature on second language (L2) fluency is replete with descriptions of fluency and its influence with regard to English as an additional language, little is known about what fluency features influence judgments of fluency in L2 French. This study reports the results of an investigation that analyzed the relationship between…

The important yet under-researched role of item writers in the selection and adaptation of texts for high-stakes reading tests is investigated through a case study involving a group of trained item writers working on the International English Language Testing System (IELTS). In the first phase of the study, participants were invited to reflect in…

This study explores how second language (L2) texts written by learners at various proficiency levels can be classified using computational indices that characterize lexical competence. For this study, 100 writing samples taken from 100 L2 learners were analyzed using lexical indices reported by the computational tool Coh-Metrix. The L2 writing…

The authors present a model of lexical proficiency based on lexical indices related to vocabulary size, depth of lexical knowledge, and accessibility to core lexical items. The lexical indices used in this study come from the computational tool Coh-Metrix and include word length scores, lexical diversity values, word frequency counts, hypernymy…

Investigated the effect of semantic inconsistency on performance of an auditory sentence-grammaticality judgment task among school-age children with and without language-learning disabilities. Children judged grammatical correctness of semantically consistent sentences and correctness of grammatically inconsistent sentences. Results are discussed.…

Examines ways in which meaning is extracted in authentic language contexts and claims that whatever level of language people use deviates from some putative ideal. Such deviant use of language is common to everyday conversation. Examines two common contexts in which authentic but deviant language is the medium of communication. (Author SED)
