This study compared Korean adult learners' English speech in dialogic and monologic tasks, measuring 57 college students' oral proficiency in terms of holistic and analytic grades. The statistical analyses were focused on two questions: (1) how much do the holistic grades of oral proficiency and analytic grades of the four linguistic features…

This study explored how task complexity, writing behaviors (i.e., pausing and revision behaviors), and writing performance (i.e., task completion, coherence and cohesion, language use, and expression and tone) influence and relate to each other. Thirty advanced-level Korean EFL undergraduates completed writing tasks differing in complexity. A…

The Cognition Hypothesis postulates that more cognitively complex tasks can trigger more accurate and complex language production, thereby advancing second language (L2) development. However, few studies have directly examined the relationship between task manipulations and L2 development. To address this gap, this article reviews, via an analytic…

This paper investigated the "be"-insertion phenomenon in L2 English. L2 learners often insert "be"-forms before thematic verbs, creating nontargetlike forms (e.g. "She is love ice cream"). Based on L2 data from learners of topic-prominent L1s, a group of researchers have claimed that such "be"-forms are…

By adopting a usage-based approach to language acquisition, this study investigated the emergence and development of L2 constructional knowledge. A total of 19 English verb-argument constructions (VACs) and their associated verbs were extracted from a learner corpus and three verbal fluency tasks, each conducted in L1 and L2 English and L1 Korean.…

This study investigated whether task complexity may affect L2 speaking performance as predicted by the Cognition Hypothesis (Robinson, 2011), and whether the effect of task complexity may interact with individual differences in working memory capacity. A total of twenty Korean advanced-level EFL learners performed two separate picture description…

Intelligibility of second language (L2) English has become an important goal in English pronunciation teaching. However, intelligibility research primarily focused on L2 English users and L2 production features; only a handful of studies have examined other effects on the intelligibility of L2 English. In line with the three-part model of…
