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…

Fifty advanced Korean learners of English participated in a grammatical acceptability judgment task and a self-paced reading task.

Based on L2 data from learners of topic-prominent L1s, a group of researchers have claimed that such "be"-forms are…

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.…

The study employed a…
