Research suggests that heterogeneous life experiences (e.g. multilingualism) might facilitate the development of mental flexibility. The current paper presents the conceptual replication of a study originally presented by Greve and colleagues [Greve, W., Koch, M., Rasche, V., and Kersten, K. (2021). Extending the Scope of the 'Cognitive Advantage'…

Many second language (L2) learners participate in study abroad (SA) experiences believing their choice will be synonymous with increased interaction in the L2, from which enhanced linguistic gains will ensue. Nonetheless, one open question is whether SA participants actually engage in sustained L2 interaction while they are abroad. This paper…

The current study quantitatively applies Spolsky's triangular framework of language policy, including beliefs, practices, and management, to the family domain by investigating language policy in multilingual families in Belgium's Flemish Community. Firstly, we examine whether the three components in fact call for an independent description and…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

This paper examines evidence for relationships among individual differences (IDs) in L1 achievement, L2 aptitude, and L2 achievement. It begins by providing an overview of my academic journey from L1 educator to L2 researcher and explains the development of the Linguistic Coding Differences Hypothesis (LCDH). Next, I review Peter Skehan's…

The Canadian Academic English Language (CAEL) assessment is a proficiency test for university admission. Most research has focused on the paper edition, not the recent computer edition (CE). Validity research on other proficiency tests found that relationships between proficiency scores and academic achievement measures can be tenuous because…

Linguistic complexity serves as an important measure of second language (L2) writing development. Complexity indices, however, rarely feature in the studies of learner languages other than English. Additionally, L2 writing studies have been criticized for the lack of consistency in defining proficiency. The current study addresses these gaps by…

Drawing on theoretical insights from a complex dynamic systems framework, this work explores the ways that learner selves, as they relate to learning and using languages, manifest across different contexts and timescales and emerge in interaction with various factors. First, a broad overview of dynamically-oriented L2 motivation research is…

Across languages, lexical items specific to infant-directed speech (i.e., 'baby-talk words') are characterized by a preponderance of onomatopoeia (or highly iconic words), diminutives, and reduplication. These lexical characteristics may help infants discover the referential nature of words, identify word referents, and segment fluent speech into…

This study examined dual language learners' (DLLs n = 24) and English-only (EO n = 20) children's expressive and receptive language in kindergarten (M[subscript age] = 5.7 years) as well as the relation to peers' language use. Expressive language skills (vocabulary diversity, syntactic complexity) were measured in the fall, winter, and spring…

This longitudinal study examined the moderating roles of language use and gender in the relations between maternal depressive symptoms and child internalizing behaviour problems in 242 preschool children (48% girls) enrolled in Head Start centres. Teachers and parents completed the "Child Behavior Checklist for Ages 1 1/2-5." Mothers…

We advance a tripartite framework of language use to encompass language skills, the practice of language skills, and the subjective experiences associated with language use among Mexican-origin adolescents who function as language brokers by translating and interpreting for their English-limited parents. Using data collected over 2 waves from a…

There is emerging evidence that collocation use plays a primary role in determining various dimensions of L2 oral proficiency assessment and development. The current study presents the results of three experiments which examined the relationship between the degree of association in collocation use (operationalized as t scores and mutual…

The importance of learning an Aboriginal language has been documented, yet associations with positive educational outcomes are inconclusive. Previous research in the area has been limited by small sample studies, lack of comparison groups, and the omission of the consideration of socio-demographic factors and cultural activity participation. This…

The purpose of this study was to examine the relationship between school-based kindergarten transition practices and student achievement and executive functioning using recent, nationally representative data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11. The analysis employed 3-level hierarchical linear models and…
