The Involvement Load Hypothesis (ILH) is a framework for designing vocabulary-learning tasks which was proposed by Batia Laufer and Jan Hulstijn in 2001. It assumes that task effectiveness depends on three components induced by a task: a motivational component (need) and two cognitive components (search and evaluation). The hypothesis has been…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

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…

This study investigates the hypothesis that non-isomorphic syntax-semantics mappings pose a greater challenge for non-native (L2) than for native (L1) speakers, focusing on a previously understudied phenomenon. We carried out an antecedent judgment task with L1 German and L1 Russian-speaking, proficient L2 learners of German to examine Condition C…

The current study investigates the influence of L2 English learners' belief about their interlocutor's English proficiency on phonetic accommodation and explores whether interaction-induced phonetic convergence could improve L2 English learners' vowel pronunciation. Results from two experiments show that when the subjects believed that their…

The current study investigates second language acquisition of Chinese object ellipsis to probe the development of features transferred from learners' native language without robust confirming or disconfirming evidence in the second language (L2) input. It is argued that Chinese allows object ellipsis licensed by a verb with a [VCase] feature but…

Event-related potentials (ERPs) have become widespread in second language acquisition (SLA) research and a growing body of literature has been produced in recent years. We surveyed 61 SLA papers that use ERPs to study L2 sentence processing in healthy late learners. Our main aim was to provide a critical summary of findings from the decade…

This paper explores the adoption of the Communicative Language Teaching (CLT) approach in primary classrooms, emphasizing that language acquisition is best achieved through meaningful communication rather than rote memorization. Drawing on Krashen's Input Hypothesis and Vygotsky's socio-cultural theory, the study highlights the importance of…

In the English "tough" construction (TC), knowledge of "tough" movement is necessary for target performance (the object-interpretation only; e.g. "John is easy to see" e). The acquisition of the English TC raises a learnability problem for first-language (L1) Korean learners of English as a second language (L2): (1)…

This study investigates the effects of four online vocabulary tasks on second language (L2) vocabulary acquisition among learners of different proficiency levels. While tasks are widely used to support L2 vocabulary learning, the efficacy of a task depends on the interplay between task and learner factors. Thus, choosing an appropriate task…

A large amount of literature exists on how native speakers derive and process pragmatic inferences, yet few studies have examined the issue in second language learners, despite a controversial debate of second language (L2) ultimate attainment of phenomena situated at external interfaces. This study contributes to the debate on the integration of…

This study investigated Thai EFL learners' acquisition of English dative constructions, i.e., Prepositional Dative (PD) and Double Object (DO) constructions employing Radford's (2004) Minimalist accounts as a framework and Acceptability Judgment as a task. Two hypotheses were formulated. Firstly, the English PD would be accepted more readily than…

Many studies have explored the second language (L2) acquisition of relative clauses (RCs) and whether L2 speakers transfer a resumptive strategy from first language (L1) to L2. While evidence seems to suggest that there are significant L1-L2 differences in the processing of RCs, relatively little is known about the source of non-target-like L2…

The Interface Hypothesis proposes that second language (L2) learners, even at highly proficient levels, often fail to integrate information at the external interfaces where grammar interacts with other cognitive systems. While much early L2 work has focused on the syntax-discourse interface or scalar implicatures at the semantics-pragmatics…

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…
