This article presents a theoretical review of and methodological guidelines for the study of two key notions in second language acquisition research, complexity and difficulty. The term "complexity" has gained considerable currency over the past decades and has taken on a wide range of meanings. We argue for a more restricted…

Background: The ability to understand the mental state of others (social cognition), as well as language, is crucial for children to have good social adaptation. Social cognition (SC) has been shown to be a hierarchical model of three factors (Cognitive, intermediate and affective SC) interrelated with linguistic processes. Children on the autism…

This dissertation deals with the perception of the aspirated coda /s/ by Spanish L2 learners. Second language research, with some exceptions, focuses on whether L1English-L2 Spanish learners can perceive the aspirated variant, showing that only advanced learners with time spent in s-weakening regions succeed at the task. L2 studies about…

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…

Construction Grammar has been a prominent framework in linguistic research for nearly three decades, attracting scholars from various disciplines, including language acquisition, corpus linguistics, and psycholinguistics. While considerable progress has been made in understanding the first language (L1) construction learning of various languages,…

This article traces the intellectual roots and developments of the notion of competence in second language (L2) teaching and research. Since L2 teaching and research invariably concern competence of some sort (linguistic, communicative, interactional, or otherwise), there have been countless attempts to define competence from diverse theoretical…

Coalson, Peña, and Byrd published a systematic review that demonstrated significant limitations in the language profile descriptions for multilingual participants who stutter for studies that were completed through September 2011. Given the average number of investigations of multilingual speakers who stutter has shifted from one study every 5…

In the past two decades, syntactic complexity measures (e.g. the length or number of words per clause/t-unit/sentences and number of clauses per t-unit/sentence, and types of clauses used) have been widely used to determine and benchmark language proficiency development in speaking and writing. (Norris and Ortega 2009; Lu 2011). However, the…

This paper represents a summary and discussion of the three studies presented at the morning session of the Fall 2022 JALT Vocabulary SIG. The papers, which were written by Ali Al-Hoorie, Masaki Eguchi, Derek Canning, Stuart McLean, Christopher Nicklin, and Joseph Vitta, represent a range of topics and study designs that are common in recent…

This paper discusses the association between bilingualism and creativity considering the contribution of executive functions in this relationship. The studies which investigated the relationship between bilingualism, creativity and executive functions are reported. In the psychology literature, divergent thinking and creativity are synonymous…

Globally classrooms are increasingly linguistically diverse. Research often oversimplifies lived linguistic heterogeneity as binary variables: native versus non-native. Linguistic distance (LD) measures allow a fine-grained operationalization of linguistic diversity in foreign language education. This study investigated associations of cognate LDs…

Indigenous communities, linguists, teachers, and language activists have been developing methods to revitalise endangered languages over several decades. Not only are these methods diverse, they are usually implemented in various ways according to local needs and aspirations. Language revitalisation methods focus on proficiency, but there is also…

Elicited imitation tasks (EITs) have been proposed and examined as a practical measure of second language (L2) proficiency. This study aimed to provide an updated and comprehensive view of the relationship between EITs and other proficiency measures. Toward that end, 46 reports were retrieved contributing 60 independent effect sizes (Pearson's r)…

In my research I examine the linguistic practices of Moroccans in Spain, many of whom speak Moroccan Arabic as well as Modern Standard Arabic, Tamazight, French, English and Spanish at varying levels of proficiency. As part of my research, I conducted a 10-month linguistic ethnography. I was able to rely on my native English and near-native…

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…
