The appropriate amount of first language (L1) and second language (L2) to use in L2 learning has been constantly debated (e.g., Cummins, 2007; Hall & Cook, 2012). This study situates the debate of L1 and L2 use in the context of vocabulary learning from reading. By examining the potential moderating factors on the comparison of L1 and L2…

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 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.…

"How can teachers help students improve their second language (L2) speaking accuracy?" This is a question that most L2 educators ask themselves every day. Although L2 writing is a popular topic among Second Language Acquisition (SLA) researchers, the consideration that L2 writing has the potential to act as a scaffold for L2 speaking…

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…

For many people, learning a second language as an adult is a challenging endeavor. Much interest in the study of adult second language learning has concerned the type of input that learners receive in their second language, with findings suggesting that second language learners are often exposed to a register of speech called 'foreigner talk' that…

Research suggests that proficient second language (L2) learners are able to leverage their metacognitive knowledge and apply strategies that improve their listening comprehension. However, it remains unclear whether strategy use is directly related to listening success, or whether it is moderated by vocabulary knowledge and/or other individual…

The present study investigates the time course of acoustic cue integration in the processing of the Korean three-way laryngeal stop contrast by native Korean listeners and English second language (L2) learners of Korean. As such, this study seeks to understand how native listeners and L2 learners weight and integrate fine-grained acoustic…

Bilingual advantage literature proposes that bilinguals perform significantly better on tasks of executive functioning when compared to monolingual individuals. This study explored the theory of the bilingual advantage when individuals were exposed to an increased cognitive load due to emotionally valenced stimuli. Due to the limited capacity of…

The focus of the classroom karaoke study was to determine if singing could help Japanese EFL students improve their English pronunciation skills. Five students from a private English language school in Japan were the main participants. They ranged in age (from 20-50) as well as in English proficiency level (from beginning to advanced). After the…

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…

Despite the importance that learners must place on using prosody appropriately in EIL interaction, pragmatic functions of prosody have been largely disregarded in teaching materials and classroom instruction (Nikolic, 2018). Moreover, with a recent change in classroom paradigms instigated by the global development of educational technologies and…

Skill acquisition theorists conceptualize second language (L2) learning as the acquisition of a set of perceptual, cognitive, and motor skills. The dominant view in skill acquisition theory is to regard L2 skill acquisition as a three-stage process "from initial representation of knowledge through initial changes in behavior to eventual…

Lexical inferencing is considered a listening strategy that is commonly employed by advanced EFL (English as a Foreign Language) listeners and a factor that contributes to successful listening comprehension. However, investigations of the factors that influence inferencing success in listening as well as how much each factor contributes to success…
