Building up on studies that have revealed L2 transfer of imperfective meaning from one Romance language into another [Salaberry, M. R. (2005). Evidence for transfer of knowledge of aspect from L2 Spanish to L3 Portuguese. In D. Ayoun & R. Salaberry (Eds.), "Tense and aspect in romance languages: Theoretical and applied perspectives"…

Recent studies in the second language acquisition of negation have focused on polarity items and their licensing contexts. Although several studies show a correlation between higher degrees of second language (L2) proficiency and the acquisition of the target L2 structures, less attention has been given to the relation between the acquisition of…

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 explored a way to help Japanese university students write longer essays while maintaining grammatical accuracy. Participants were three groups of students enrolled in a one-year EFL course in different academic years (N = 111), and the number of words they wrote in 30 minutes and the number of errors made per 100 words were compared. To…

This study investigated the interactions among different cognitive abilities, linguistic structures, and the efficacy of different corrective feedback (CF) types. The cognitive abilities examined were declarative and procedural memory. The target linguistic structures were English regular and irregular past tense forms. In terms of the…

This mixed methods study draws upon theoretical perspectives from usage-based linguistics (UBL) and variationist sociolinguistics to explore four learners' use of second language (L2) Spanish present tense indicative verbal inflectional morphology (i.e., simple present conjugations). The study compares the frequency and distribution of students'…

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…

This study explores the effects of receptive derivational affix knowledge, derivative frequency, part of speech, and vocabulary breadth on production of derivatives. Twenty-one speakers of English as a first language and 107 learners of English as a second language were asked to produce derivatives for 90 prompt words on a decontextualized…

It has been shown that morphological skills are particularly enhanced in bilingual children, whereas they are compromised in dyslexics. The aim of this work is that of investigating how bilingualism interacts with dyslexia in a task measuring the subject's morphological abilities, to verify if the advantage typically found in bilingualism arises…

This multifactorial corpus-based exploration of past tenses focuses specifically on the present perfect (PP) versus simple past (SP) alternation in intermediate-to-advanced learner English produced by French and German native speakers. While existing work on past tenses in L2 has traditionally focused on the role of lexical aspect in the…

This study aimed to investigate the effectiveness of a new instructional toolkit for improving English grammar skills, particularly verb tense structures, among Thai EFL students. The research objectives were (1) to evaluate the toolkit's effectiveness in enhancing students' English grammar skills in verb tense structures; (2) to examine the…

It is generally agreed that first language (L1) morphological awareness, the ability to reflect upon, analyze and manipulate morphemes and morphological structure of words, can transfer and facilitate second language (L2) reading subskill acquisition. However, the facilitative role of L1 morphological awareness is unclear in the literature…

Previous studies on bilingual children have shown a significant correlation between first language (L1) and second language (L2) morphological awareness and a unique contribution of morphological awareness in one language to reading performance in the other language, suggesting cross-linguistic influence. However, few studies have compared…

In response to McLean (2021), Laufer (2021) makes three claims which are either not supported by research or are based on studies with important limitations. First is that a vocabulary size, instead of a level, can be used to match learners with lexically appropriate materials despite test creators and research not supporting this. Second is that…

The study aimed to examine the relationship between morphological knowledge and reading comprehension ability among college-level English as a foreign language (EFL) students. One hundred and twenty-one students participated in this study and they completed two morphological knowledge measures (morpheme-form knowledge and morpheme-meaning…
