According to cognitive psychologists, consistent practice (i.e., tasks with a high degree of similarity) of a skill leads to the development of automaticity, with the degree of automatization being increased if the practice also involves exact repetition. Practice is skill specific, meaning that practicing one skill does not automatize related…

The imagination effect occurs when students learn better from imagining concepts and procedures rather than from studying them. Cognitive load theory explains the effect by better use of available working memory resources and increased productive, intrinsic cognitive load. The effect has been found in numerous empirical studies. However, in the…

This study investigates whether dynamic visual enhancement affects the recall of second language (L2) vocabulary and whether working memory interacts with visual enhancement and vocabulary recall. Participants in four groups completed a pre-test, immediate post-test, and delayed post-test that measured the effects of the type of dynamic…

This study investigated the extent to which individual differences in working memory (WM) mediate the effects of captions with or without textual enhancement on attentional allocation and L2 grammatical development, and whether L2 development is influenced by WM memory in the absence of captions. We employed a pretest-posttest-delayed posttest…

This study investigated the effects of captions on the listening comprehension of vlogs. A total of 96 EFL learners watched three vlogs under one of three conditions: L2 captions, L1 captions, and no captions. Each group included low-, mid-, and high-level proficiency learners. The vlogs differed in the pictorial support of the audio, with Vlog 1…

Captioned video is widely used to enhance second language (L2) learners' exposure to oral input beyond the classroom setting, and captioning has been found to provide an instantaneous, useful visual aid for parsing and understanding L2 oral discourse. Nevertheless, a meta-analysis has shown that captioning exerts a selective effect on L2 learners…

There is mounting evidence that phonological memory (PM), a sub-component of working memory, is closely related to various aspects of second language (L2) learning in a variety of populations, suggesting that PM may be an essential cognitive mechanism underlying successful L2 acquisition. This article provides a brief critical review of the role…
