Although the development of implicit grammatical knowledge is highly desirable, not all grammatical constructions could be learned implicitly. Therefore, one of the ultimate objectives of most English as Foreign Language (EFL) classrooms is to aid learners in developing their (automatic) explicit grammatical knowledge. Using progressively complex…

The present work examines the impact of code-switching (CS) on novel word learning in adult second language (L2) learners of Spanish. Participants completed two sessions (1-3 days apart). In the first session, they were taught 32 nonwords corresponding to novel creatures. Training occurred across 4 conditions: (1) a sentence in English only, (2) a…

To unlock language proficiency among learners, speaking is regarded to be an essential and crucial aspect to master, not only for learning purposes but for recognized communication dynamics. Language learning has numerous critical aspects. To be lacking in speaking proficiencies has been noted to impart negatively toward language learning. This…

This study explored how the first language (L1) influences discourse marker use in second language (L2) speech. Some studies (e.g., Liu, 2013; Sankoff et al., 1997) have addressed the issue of L1 transfer of discourse markers in L2 speech, suggesting that non-native speakers' L1 use may influence the frequency and usage of English discourse…

Previous literature has shown that voicing contrast is a difficult feature for Chinese-English emergent bilingual learners of L3 Spanish (Bravo Diaz, 2020; Chen, 2007; Zhang, 2022). The production of voicing contrast in stops has been broadly investigated in second and third language studies (e.g., Zampini, 1998; Llama, 2010; Wrembel, 2014), but…

This study investigated the effect of Chatbot-Assisted Dynamic Assessment (CA-DA) on vocabulary learning and provided insights into learner abilities drawn from its implementation. Through the use of mediating chatbots, this study implemented DA to multiple learners simultaneously and provided each learner with human-like interaction. The chatbots…

This dissertation analyzes the production and perception of lexical stress in trilinguals' first, second, and third languages (L1, L2, and L3) to evaluate how the cue-weighting transfer hypothesis applies to L3 acquisition. According to this hypothesis, acoustic cues to stress have different weights across languages, and results from both…

Chinese character learning requires various reading subskills, such as radical awareness and character knowledge. Radical awareness refers to learners' ability to identify, analyze, and apply semantic radicals in compound characters. Previous studies have shown that radical awareness and character knowledge facilitate learning semantically…

Learning to mark for tense in a second language is notoriously difficult for speakers of a tenseless language like Chinese. In this study we test two reasons for these difficulties in Chinese-English sequential bilingual children: (1) morphophonological transfer (i.e., avoidance of complex codas), and (2) interpretation of -"ed" as an…

We used delayed sentence-picture verification tasks to investigate multilingual perceptual representations. In experiment 1, participants listened to sentences with implied shapes. After a 10-min interval, they judged whether pictures had been mentioned in the preceding sentences or not. Results in experiment 1 showed significant match effect in…

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…

Recent research on advanced theory of mind (ToM) has questioned the extent to which existing ToM measures capture a single construct, particularly for groups understudied in developmental research. The present study examined the factor structure of one of the most commonly used advanced ToM measures, the Strange Stories task, in samples of low-…

Despite frequent reliance on teacher and parent ratings of children's behavior for multi-informant assessment, agreement between teachers' and parents' ratings is low. This study examined the predictive utility of teacher and parent ratings for children's self-regulatory outcomes (i.e., executive function, continuous performance task) in four…

There has been much debate in assessment research about the inclusion of Global English accents in high-stakes listening tests. This study explored test-takers' attitudes toward the inclusion of different English accents in the Duolingo English Test (DET) 2021 test version and their associations with listening test scores. One hundred sixty…

While task-based language teaching (TBLT) is a teaching methodology favoured by the Chinese Ministry of Education, it has not been sufficiently researched to be validated empirically in practice in the EFL classroom. Few studies have investigated teachers' responses to TBLT in the Chinese college English context. This research contributes to…
