In order to explore the cognitive mechanisms and processing involved in incidental vocabulary acquisition, this study examines whether two crucial cognitive factors, attention and working memory, influence incidental vocabulary acquisition during second language reading. Employing a combined online-offline approach, attention, working memory, and…

The tantalizing prospects of learning benefits from multimodal conditions on second language (L2) learning in general, and L2 vocabulary development in particular, have important implications. Indeed, opening a language learning app on any device provides the immediate experience of simultaneous input modalities, and a wide range of input types.…

In light of mixed findings in existing input enhancement research, Issa and Morgan-Short in a 2019 article urged researchers to compare the relative effects of input enhancement that taps into learners' attention to the external format of second language (L2) target forms (e.g. through capitalizing or boldfacing the forms) and input enhancement…

Recent studies have suggested that language aptitude is a domain-general and flexible trait to acquire foreign languages, regarding various cognitive abilities such as memory systems as its crucial components. Despite a growing interest in working memory, however, much remains unknown about the impact of associative memory on language aptitude.…

Incidental vocabulary learning through reading may be influenced by a range of learner-internal as well as learner-external factors. This study, specifically, examined the potential impacts of three factors: text type, prior L2 vocabulary knowledge, and working memory capacity. Forty-six 1st grade high school students in Korea completed a battery…

Multimodal input can significantly support second language (L2) vocabulary learning and comprehension. However, very little research has examined how L2 learners, especially young learners, allocate attention when exposed to such input and whether learning from multimodal input can be explained by attention allocation. This study therefore…

This paper presents a new method for accurately measuring the vocabulary size of second language (L2) learners. Traditional vocabulary size tests (VSTs) are limited in capturing a tester's vocabulary and are often population-specific. To overcome these issues, we propose an intelligent vocabulary size measurement method that utilizes massive robot…

Working memory (WM) is essential to vocabulary learning. However, limited attention has been paid to young beginner learners' vocabulary development under various task conditions from the perspective of WM. This study investigates how two types of WM--complex WM and phonological short-term memory--may influence two instructional approaches (i.e.,…

Lexical ability, an umbrella term to cover various knowledge and skills pertaining to words in print, is a key component in reading comprehension. Little is known how different facets of lexical ability jointly contribute to L2 reading comprehension and how the contributions may differ between higher- and lower-proficiency L2 learners. This study,…

The present study aims to examine incidental vocabulary learning from different genres of captioned videos while considering frequency, vocabulary knowledge, comprehension, and working memory. A total of 210 learners who learn English as a foreign language (EFL) were assigned to 6 treatment conditions that differed in terms of video genres…

The present dissertation reports two experiments that examine implicit and explicit language learning methods and their impacts on early vocabulary, grammar, and phonological acquisition, in addition to working memory, proactive/reactive control, and fluid intelligence, as well as learner motivation. Experiment 1 investigated adult L2 acquisition…

Working memory (WM) may be an essential component of incidental vocabulary learning and retention from captioned videos. However, how WM affects young learners' incidental vocabulary learning under different types of captions remains unclear. The present study employs a between-subject research design. The main purpose is to examine how two types…

This study investigates the effects of three word-focused exercise conditions on vocabulary learning. The exercises were developed based on the involvement load hypothesis. This study also explores how individual differences (e.g. second-language English proficiency level and working memory) affect vocabulary learning outcomes. A total of 180…

Working memory plays an important role in learning since it serves as the buffer between past sensations and future behavior, making it essential to understand not only how we encode and recall sensory information in memory but also how we plan for its upcoming use. This study examined the effect of working memory training on vocabulary recall and…

This study aimed to examine incidental learning of multiword expressions (MWEs) from bilingual captioned videos among language minority students. The participants consisted of 403 language minority university students enrolled in the Preparatory Year Programme (PYP) in the Southern part of China. The study evaluated participants' vocabulary…
