This article presents a conceptual replication of Hashimoto and Egbert (https://doi.org/10.1111/lang.12353), a study that featured multivariate models where lexical sophistication variables accounted for word difficulty (yes-no recognition) better than frequency alone among learners of English as a second or foreign language from North America.…

An extensive body of research has investigated the role of syntactic complexity in gauging the linguistic complexity of reading texts, particularly for the purpose of determining their grade appropriateness. However, little such research has focused on adapted teaching materials for English as a foreign language (EFL) contexts, and to date there…

We investigated how learner factors, such as vocabulary proficiency, strategy use, and working memory, are associated with successful corpus-based second language (L2) vocabulary learning, in which learners are encouraged to analyze and explore large, structured collections of authentic language data (i.e., corpora) to resolve their lexical issues…

The aim of this study was to investigate deaf and severely hard-of-hearing students' foreign language learning characteristics. In order to provide a better understanding of the challenges this group of learners face, a mixed methods study was designed including a questionnaire survey to provide generalizable results for our context and an…

Working with Korean university-level learners of English, this study provides a detailed analytical comparison of 2 task work groups that were video-recorded, with 1 group scoring very high and the other relatively low based on the results of a Group Work Dynamic (GWD) measuring instrument. Adopting a complexity theory (CT) perspective and…

In research on task-based learning and teaching, it has traditionally been assumed that differing degrees of cognitive task complexity can be inferred through task design and/or observations of differing qualities in linguistic production elicited by second language (L2) communication tasks. Without validating this assumption, however, it is…

While there exists a considerable body of literature on task-based difficulty and second language (L2) fluency in English as a second language (ESL), there has been little investigation with French learners. This mixed methods study examines learner appraisals of task difficulty and their relationship to automated utterance fluency measures in…

The present study explores the use of conjunctions in simple versus complex argumentative tasks performed by second language (L2) learners as a specific measure for the amount of reasoning involved in task performance. The Cognition Hypothesis (Robinson, 2005) states that an increase in cognitive task complexity promotes improvements in L2…
