The Interface Hypothesis proposes that the pragmatic-discursive interface with syntax is more vulnerable to crosslinguistic influence than the syntactic-semantic interface [Tsimpli, Ianthi, and Antonella Sorace. 2006. "Differentiating Interfaces: L2 Performance in Syntax- Semantics and Syntax-Discourse Phenomena." In Proceedings of the…

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…

Family language policy (FLP) impacts the maintenance of heritage language(s) in the family domain, where parents play a crucial role in making language-related decisions for their children. Globalisation, immigration, the COVID-19 pandemic, and digital communication have all affected FLP. Studies are now calling for examining how dispersed…

aaaPlural marking differs across languages. Some must mark plurality using an overt morpheme (e.g. English, Russian), while others mark it optionally (e.g. Korean) or lack an explicit plural morpheme (e.g. Chinese). This crosslinguistic difference in plural marking has received much attention in research exploring language transfer in the context…

As one type of the most extensively used sentences, English questions are must-learn grammatical structures for learners of English as a foreign language (EFL). However, it is commonly seen that English learners across proficiency levels produce ungrammatical English questions. To determine the source of learners' erroneous production, we…

This study aimed to investigate the production of stress in English compound nouns and phrasal verbs by L1 Thai learners. Based on the Interlanguage Hypothesis (Corder, 1982; Selinker, 1972), it was hypothesized that (1) there is a positive relationship between English proficiency levels and accuracy in stress assignment in compound nouns and…

The population of emergent bilingual students in the United States is growing rapidly, requiring that teachers be prepared to provide them an effective education. Inadequate preparation of teachers to work with these students indicates the need to revise the ways that teacher education programs address this issue (Palmer & Martínez, 2013),…

Literacy in a first language or in additional languages involves a set of complex cognitive, social, and linguistic skills that develop over time. However, pedagogical materials for low-proficiency English as an additional language (EAL) learners tend to target low-level literacy skills only, such as responding to fact-based questions. Materials…

In content and language integrated learning (CLIL) classrooms, it is assumed that non-language content subjects provide more authentic communicative contexts for students to learn a foreign/second/additional language (L2). However, learning abstract concepts and academic language in an L2 simultaneously is also challenging for CLIL students. It is…

This research investigated avoidance behaviour, one of the strategies L2 learners may resort to because of L1-L2 differences, or the non-existence of L2 structures for L1 learners, i.e. the Avoidance Behaviour Hypothesis (Schachter 1974). However, based on the Factors of L2 Non-Avoidance Hypothesis (FNAH) (Thiamtawan & Pongpairoj, 2013, 2019),…

There is quite a bit of evidence showing that the experience of learning an L2 will help in learning an L3, but as far as we know, very little research has investigated the possible impact of L3 learning on the already existing and still developing L2 system within the learner. According to Complex Dynamic Systems Theory (CDST), language…

In recent years, despite the fact that many researchers have devoted much of their attention to second language attrition, not much focus has been given to first language attrition (FLA) specifically among Iranian immigrants. The present study attempts to describe FLA in the semantic domain of idiomatic expression and effect of length of residence…

This research paper presents a quasi-experimental empirical study investigating the effects of structured input and structured output tasks on the acquisition of English causative forms. This research is framed on VanPatten's (1996) input processing theory. The grammatical form chosen for this investigation is affected by a processing strategy…

How languages are acquired and what stages learners go through has been the focus in language teaching area, and this cross-sectional study investigated the use of English adverbs by elementary, pre-intermediate and intermediate level Turkish EFL students at Anadolu University School of Foreign Languages by analyzing it from acquisitional…

Using Swain's (1985) output hypothesis as a basis, this article investigated the effect an immediate repeated oral task had on the performance of participants. Two groups of beginner learners of English as an additional language in Brazil performed a decision-making oral task in groups. Drawing from Lynch and MacLean's (2001) carousel task, the…
