Through the application of the Douglas Fir Group's transdisciplinary framework, this study investigated how three levels of mutually dependent influence (i.e., the micro level of social action and interaction, meso level of sociocultural institutions and communities, and macro level of ideological structures) operate across time and space to shape…

This mixed-methods study explores the efficacy of a multidimensional identity measurement tool that aims to represent the diverse language experiences of heritage language learners (HLLs) and heritage language speakers (HLSs). Drawing on the thematic commonalities across 13 definitions of HLLs, a questionnaire was developed to capture age of…

The effects of learner- and task-related variables on second language (L2) writing syntactic complexity (SC) have been extensively investigated. However, previous research has rarely assessed the reliability of computational tools for analyzing the SC of L2 spoken production, and we know less about the effects of such variables on L2 speaking SC.…

While an elicited imitation test (EIT) has been widely used as a measure of oral proficiency in second language acquisition (SLA) research, it is still unclear the extent to which memory capacity impacts EIT performance. In light of this gap, the present study sought to clarify the nature of elicited imitation by examining the relative…

The Seal of Biliteracy (SoBL) is a language policy that has gained traction across the United States as stakeholders seek to recognize students' competencies in languages other than English. Despite its potential to enhance language proficiency and encourage participation in language education, the SoBL has been unevenly implemented, with…

Learner corpus studies using syntactic complexity as a construct for characterizing learner proficiency have found that higher proficiency permits learners to produce more complex syntactic structures. However, the majority of previous studies have focused on writing, almost exclusively with adult second language (L2) learners. Given the…

This study examines first language (L1) English transfer in the acquisition of plural noun semantics in second language (L2) Arabic. Drawing on previous research on the L2 acquisition of plural noun interpretation, the study presents and discusses new production data of specific and generic definite plurals by English-speaking learners of Arabic…

Current quantitative methods in second language (L2) acquisition have proven useful in examining how phraseological unit production changes over time. However, these methods are limited in that they do not allow for the analysis of individual differences in those changes. This study demonstrates the potential for Latent Curve Modeling, a type of…

It has been noted that Chinese shows both satellite- and verb-framed properties (Beavers, Levin, & Tham, 2010; Slobin, 2004), a fact that offers the opportunity to explore the typological influence of learners' dominant language because they can choose either option to describe the same motion events and be grammatically correct. This study…

Research on multilingual acquisition has investigated various combinations of languages to identify the factors determining how learners express motion. Our research examines the semantics of motion expression in learners whose first language (L1) exhibits more variation than their foreign language (L2/L3). The present study compares upward motion…

This article investigates bilingual versus monolingual construal of manner of motion in speech and gesture across three languages--Mandarin, Japanese, and English--argued to be typologically distinct in speech and co-speech gesture (Brown & Chen, 2013; McNeill, 2001; Slobin, 2004b; Talmy, 1991). Narrative descriptions of motion were elicited…

The aim of the current study is to investigate motion event cognition in second language learners in a higher education context. Based on recent findings that speakers of grammatical aspect languages like English attend less to the endpoint (goal) of events than do speakers of nonaspect languages like Swedish in a nonverbal categorization task…

This study compares Arabic L1, L2, and heritage speakers' (HS) knowledge of plural formation, which involves concatenative and nonconcatenative modes of derivation. Ninety participants (divided equally among L1, L2, and heritage speakers) completed two oral tasks: a picture naming task (to measure proficiency) and a plural formation task. The…

This study investigates relations between second language (L2) lexical input and output in terms of word information properties (i.e., lexical salience; Ellis, 2006a). The data for this study come from a longitudinal corpus of naturalistic spoken data between L2 learners and first language (L1) interlocutors collected over a year's time. The…

This study was an examination of the relationship of lexical richness to the quality of English as a second language (ESL) learners' oral narratives. A computational system was designed to automate the measurement of 3 dimensions of lexical richness, that is, lexical density, sophistication, and variation, using 25 different metrics proposed in…
