This study examines context effects on lexical processing by low-proficiency Japanese learners of English during sentence comprehension, and the role of individual differences in verbal working memory (WM). Thirty Japanese learners of English as a second language (L2) and 27 speakers of English as a first language (L1) were recruited for a…

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…

Guided by Dynamic Systems Theory (DST) and multidimensional perspectives on individual differences (IDs) in instructed second language (L2) learning (e.g., Larsen-Freeman, 2014; Sun & Zhang, 2020), this longitudinal mixed-methods study focuses on three conceptually different categories of L2 learners' IDs: working memory (WM), motivation, and…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

The sentence repetition (SR) test is considered as a promising diagnostic tool for detecting language proficiency in monolingual learners, but less is known about its potential to identify dual language learners' (DLLs) linguistic proficiency. Considering that challenges with language learning, such as developmental language disorders (DLDs), is…

Working memory (WM) is inherently dynamic and complex, being a multi-faceted system that links storage and processing components; yet it is widely understood as internal. Hence, in second language (L2) research, its connection to complex dynamic systems theory (CDST) remains underspecified. This paper seeks to bridge a gap between CDST and WM in…

Most language experiences take place at the level of multiple sentences. However, previous studies of second language (L2) comprehension have typically focused on lexical- and sentence-level processing. Our study addresses this gap by examining auditory discourse comprehension in 32 English/French bilinguals. We tested the prediction of the noisy…

Second language (L2) writing has been determined to be influenced by what is read, with language learners tending to borrow words and short phrases from input texts while writing (e.g., Wang & Wang, 2015). This phenomenon is referred to as lexical alignment. Only one empirical study has investigated the influence that the linguistic complexity…

This study examined interactions of word and learner characteristics during foreign vocabulary learning, focusing on translation ambiguity and individual differences in cognitive resources and linguistic background (language proficiency, multilingual experience). Fifty-three native Hebrew speakers and Russian-Hebrew multilinguals learned the…

According to some accounts, the bilingual advantage is most pronounced in the domain of executive attention rather than inhibition and should therefore be more easily detected in conflict adaptation paradigms than in simple interference paradigms. We tested this idea using two conflict adaptation paradigms, one that elicits a list-wide…

Studies with U.S. secondary second language (L2) learners have revealed individual differences (IDs) in first language (L1) skills and L2 aptitude and shown that these IDs are related to L2 achievement and proficiency. In this study, U.S. students were administered measures of L1 achievement, L1 cognitive processing, and L2 aptitude; followed…

This study investigated whether orthographic consistency and individual learner differences including working memory (WM), first language (L1) background, and second language (L2) proficiency affect Chinese L2 learners' literacy acquisition. Seventy American college students in beginning or intermediate Chinese classes participated in a character…

The extent to which learners benefit from instruction may be largely dependent on their individual abilities. However, there is relatively little work on the interaction between instructional effectiveness in second language learning and learner individual factors. In this study, we investigated the relationship between instruction, individual…

The current study examined the effects of text-based relational (i.e., cohesion), propositional-specific (i.e., lexical), and syntactic features in a source text on subsequent integration of the source text in spoken responses. It further investigated the effects of word integration on human ratings of speaking performance while taking into…

Adults demonstrate difficulty and pronounced variability when developing second language (L2) grammatical knowledge and reading skills. We examine explanations in terms of individual differences in working memory (WM). Despite numerous studies, the association between WM and adult second language (L2) acquisition remains unclear, and longitudinal…
