ItemAre schematic diagrams valid visual representations of concepts? Evidence from mental imagery in online processing of English prepositions(Cambridge University Press, 2024)Embodied imagery hypothesis proposes the activation of perceptual-motor systems during language processing. Previous studies primarily used concrete visual stimuli to investigate mental imagery in language processing by native speakers (NSs) and second language (L2) learners, but few studies employed schematic diagrams. The study aims to investigate mental imagery in processing prepositional phrases by English NSs and L2 learners. Using image-schematic diagrams as primes, we examine whether any mental imagery effect is modulated by target preposition (over, in), the abstractness of meaning (spatial, extended), and stimulus onset asynchrony (SOA; 1,040 ms, 2,040 ms). A total of 79 adult L2 learners and 100 NSs of English completed diagram–picture matching and semantic priming phrasal decision tasks. Results revealed interference effects on L2 processing of over phrases and under 2,040 ms SOA, but no such effects were observed in the NS group. The selective interference effects in L2 suggest different mental imagery patterns between L1 and L2 processing, and processing schematic diagram primes requires high cognitive demands, potentially leading to difficulties in integrating visual and linguistic information and making grammaticality judgments. The findings partially validate schematic diagrams as visual representations of concepts and suggest the need for further examination of schematic diagrams with varying degrees of complexity.

ItemFirst and second language speakers’ sensitivity to the distributional properties of wh-clauses: Effects of proficiency, acquisitional context, and language experience(John Benjamins Publishing Company, 2023)The present study investigates L1 and L2 English speakers’ knowledge of the wh-clausal construction along the parameters of (a) conventionality, distinguishing between high-frequency conventional and low-frequency unconventional formulations (I asked him why they agreed/why did they agree), and (b) proposition type, differentiating between interrogative versus non-interrogative proposition types (I asked / told him why they agreed). We also consider the extent to which L2 speakers’ constructional knowledge is influenced by learners’ target language experience, such as L2 proficiency, context of L2 learning (ESL or EFL), and target language exposure. Results from a judgment task revealed nuances in L1-L2 discriminatory capacities, and more importantly, differences in sensitivity to proposition type between the ESL and EFL group, but no L2 differences in sensitivity to conventionality. L2 proficiency, speakers’ length of target immersion experience, and classroom exposure were shown to also impact linguistic sensitivity, highlighting a moderating effect of target language exposure and an important role for classroom instruction.

ItemBridging Australian Indigenous language learner’s guides with SLA materials development frameworks(Taylor and Francis Group, 2022)The learner’s guide (LG) is a genre of pedagogical materials for Australian Indigenous languages, but LGs developed by field linguists are often questioned regarding their capacity to effectively facilitate language learning and, eventually, language revitalisation. This reflects a gap in the literature where applied linguistics perspectives are limited in Indigenous language studies, and vice versa. This study aims to address this gap by examining nine existing LGs published over the past four decades using a modified framework based on Tomlinson’s guidelines for second language acquisition (SLA) materials development. Findings show that the LGs are designed based on one of the three model types: (1) Type 1: non-communicative grammar-based, (2) Type 2: practice-integrated grammar-based, and (3) Type 3: text-driven meaning-based, among which the text-driven model has, theoretically speaking, the best potential to achieve pedagogical purposes. Yet, in general, existing LGs likely fail to equip learners with communicative competence. Other issues of greater complexity are also raised, including material comprehensibility and limited resources. A critical implication for the field is the necessity of empirical needs analyses for future LG development.

ItemSchematic diagrams in second language learning of English prepositions: a behavioral and event-related potential study(Cambridge University Press (CUP), 2020-09-01)In the current study of applied cognitive linguistics (CL), schematic diagrams that represent generalizations of physical-spatial experience were applied in a computer-based tutor that trained English prepositions for second language (L2) learners. Behavioral and electrophysiological (ERP) measures were used to examine whether schematic-diagram feedback provided by the tutor had an instructional advantage over the minimally informed correctness feedback. Behavioral results confirmed this prediction and further revealed that the treatment difference was more striking when the participants had a lower L2 proficiency. The ERP results also supported the prediction. Violation uses of prepositions yielded an N270 and an N400. Schematic-diagram feedback motivated significant changes in brain potentials, whereas correctness feedback failed to do so. Overall, our findings suggest that CL-inspired instruction of a relatively short duration led to significant improvements in learners’ behavioral productive performance and in their sensitivity to semantic violation of preposition use during online sentence processing. The study provided strong neurolinguistic evidence for CL-inspired pedagogy in supporting L2 learning.

ItemMultiple perspectives on group work in a multilingual context(John Benjamins Publishing Company, 2022)Abstract: Group assignments are widely used in higher education for a range of educational reasons. Although there is a large body of research on the merits of group work and factors that may contribute to successful group work, less is known about students’ and teachers’ perspectives, particularly when groups are composed of students from diverse linguistic backgrounds. The current qualitative study investigated students’ and teachers’ perspectives on group assignments in a Master of Applied Linguistics program offered by a leading research university in Australia. The program has predominantly English as an additional language (EAL) students. Teachers and students in four graduate subjects that involved group assignments were interviewed for their views and reflections. Analysis of the interview data revealed similarities and differences in perspectives in five main areas – group work benefits and challenges, group formation and assessment, and the need for pre-implementation training. The findings highlight the need for teachers to promote open discussion about the purposes and merits of group work, both pedagogical and social.

ItemLearning on the Field: L2 Turkish Vowel Production by L1 American English-Speaking NGOs in Turkey(MDPI, 2022-12)This study adopts the Speech Learning Model to investigate the first language (L1) influence as well as the effects of the length of residence and second language (L2) exposure on American English-speaking learners of Turkish in their productions of Turkish unrounded–rounded vowel pairs, with a particular focus on the vowel categories “new” to American English speakers (/y/, /œ/, and /ɯ/). L1 (English) and L2 (Turkish) speech samples were collected from 18 non-governmental organisation (NGO) workers. L2 experience was defined by whether the worker lived in an urban or regional environment in Turkey. Participants’ audio productions of the word list in L1 and L2 were segmented and annotated for succeeding acoustic analyses. The results show an interesting front–back variability in the realisations of the three vowels, including further back variants of the front vowels (/y/, /œ/) and more forward variants of the /ɯ/ vowel, with a substantial degree of interspeaker variability. While the analysis revealed no significant results for the length of residence, language experience was found to have a significant effect on the production of /y/ (F2) and /ɯ/ (F1/F2). This study forms a first step into the research of adult L2 acquisition in Turkish with a focus on L2 in the naturalistic workplace environment, rather than instructed settings. The findings of this study will contribute to the development of teaching materials for NGO workers learning Turkish as their L2.

ItemWillingness to Communicate and Second Language Fluency: Korean-Speaking Short-Term Sojourners in Australia(MDPI, 2022-05-06)The current mixed-method study investigated two groups of Korean-speaking short-term sojourners in Australia. One group (students) was composed of learners enrolled in English training programs, whereas the other group (workers) was of learners in the workplace. We administered questionnaires and a semi-structured interview to examine their willingness to communicate (WTC) in English as their second language (L2) and explored the relationship between this variable and the sojourners’ amount of L2 contact and their oral fluency in English. Our quantitative analyses show that the student group showed a higher level of WTC and amount of L2 exposure than the worker group. For both groups, WTC significantly predicted sojourners’ amount of L2 exposure. However, oral fluency was found neither to be associated with WTC nor with the amount of L2 exposure. Qualitative theme-based analysis suggests that the two sojourn groups demonstrated similarities and differences in their attitudes and motivations related to WTC and unwillingness to communicate (unWTC). The students demonstrated a stronger tendency to engage in L2 interaction than the workers, aligning with their significantly higher frequency of reported L2 exposure. The workers’ attitudes were characterized by feelings of ambivalence, with co-existence of both WTC and unWTC.

ItemModeling Input Factors in Second Language Acquisition of the English Article Construction(FRONTIERS MEDIA SA, 2021-04-22)Based on the Competition Model, the current study investigated how cue availability and cue reliability as two important input factors influenced second language (L2) learners' cue learning of the English article construction. Written corpus data of university-level Chinese-L1 learners of English were sampled for a comparison of English majors and non-English majors who demonstrated two levels of L2 competence in English article usage. The path model analysis in structural equation modeling was utilized to investigate the relationship between the input factors and L2 usage (frequency and accuracy of article cue production). The findings contribute novel and scarce empirical evidence that confirms a central claim of the Competition Model, i.e., the changing importance of cue availability and cue reliability in the frequency and accuracy of production. Cue availability was found to determine L2 production frequency regardless of level of L2 competence. Cue reliability was the input factor that differentiated competence levels. When learners stayed at a relatively lower L2 proficiency, cue reliability played an important role in influencing L2 frequency of usage rather than accuracy of usage. When learners developed increased exposure to and stronger competence in the target language, cue reliability played a significant role in determining learners' success of cue learning. The study is methodologically innovative and expands the empirical applicability of the Competition Model to the domain of second language production and construction learning.

ItemThe Emergence of Second Language Categorisation of the English Article Construction(MDPI, 2020-11-07)This study examines the emergent cognitive categorisation of the English article construction among second language (L2) learners. One hundred and fourteen Mandarin-L1 learners of English, divided into two L2 proficiency levels (low-to-intermediate and advanced), were measured by a computer-based cloze test for the accuracy and response time of appropriate use of English articles in sentential contexts. Results showed that when learners acquired the polysemous English article construction they demonstrated stronger competence in differentiating individual form-function mappings in the article construction. L2 learners’ patterns of article construction usage were shaped by semantic functions. Learners performed better on the definiteness category than on the non-definiteness categories, suggesting that learners were sensitive to the prototypicality of nominal grounding. Advanced learners demonstrated an increased sensitivity to semantic idiosyncrasy, but they lacked contextualised constructional knowledge. Competition among the functional categories and restructuring of functional categories are important ways of regularization that learners go through to acquire semantically complex systems such as articles.
