The researcher in this study applied the notions of quantitative method, theoretical linguistics and applied linguistics to examine the correlation between the linguistic theory of end-weight principle and English adjective clauses in Q1-SCOPUS applied linguistics articles and Thai EFL learners' descriptive essays. The significance of this study…

This study investigated how input frequency (i.e., type frequency and token frequency) and proficiency levels enhanced the perception of English nominal suffixes by first language (L1) Thai learners. Based on the Usage-based Account (Tomasello, 2003), it was hypothesized that input frequency, i.e., token frequency (frequency of derived forms…

This study revisits the term 'communicative competence' and delves into its details. It presents briefly various models of communicative competence to show what has been written on this term, and then it introduces the term 'communication proficiency' as a broader term that includes all competencies and skills required for communication. It…

Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

In Thailand, where students encounter both Native EnglishSpeaking Teachers (NESTs) and Non-Native English Speaking Teachers (NNESTs)--with a significant portion of NNESTs being Thai and Filipino--a gap exists in understanding how Thai students interpret the terms Native English Speakers (NESs) and NESTs. This study aimed to explore this…

A particular status of the English language as the language of international communication and connections between the nearly related English and German languages resulted in the emergence of many interlingual borrowings in the Modern English and German language vocabularies. The paper aims to consider the functioning of borrowings (loanwords) in…

We investigated whether the accuracy of grammatical morphemes in second language (L2) learners' writing is associated with usage-based distributional factors. Specifically, we examined whether the accuracy of L2 English inflectional morphemes is associated with the availability (i.e., token frequency) and contingency (i.e., token frequency…

Despite increasing number of studies on incidental vocabulary learning through viewing in a foreign language, glosses, which have been proven to have facilitative effects in incidental vocabulary learning via other modes of input, have remained underexplored in audiovisual input. The current study investigates the effects of (1) traditional gloss…

In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic…

The relationship between language and thought has fascinated us for centuries. The relationship between the two is far beyond what the two words represent on the literal level, and the discussions around it have been covered in various fields from philosophy and psychology to linguistics. Even complicating the situation, the relationship between…

The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

The amalgamation of multimedia, collaborative learning, and established language acquisition theories engenders a dynamic and continuously evolving milieu within the domain of language instruction. The objective of this study was to examine the correlation between cooperative learning, multimedia, and specific language acquisition theories across…

This study examines the correlation between the theory of pragmatic discourse of givenness and CP adverbial clauses from the two datasets: Q1 SCOPUS applied linguistics research articles and Thai undergraduate students' writing. The first set was 24 applied linguistics research articles from journals of "English for Specific Purposes"…

Second language development can be viewed as a complex and dynamic process in which learners follow non-linear trajectories and develop their language over a period of time (Larsen-Freeman, 2006). Intrinsic to the view of Complex Dynamic Systems Theory (CDST), a system is composed of hierarchical, interdependent subcomponents (learner, learner…

A great deal of research undertaken in child language development, neurolinguistics and various branches of functional and cognitive linguistics has shown that a main source of language development is the spoken input to which learners are exposed. Despite the fact that for most adult L2 learners, the greatest exposure to the L2 is the input they…
