This study examined the co-occurrence of word reading difficulty in Chinese (L1) and English as a second language (L2) and tested language and executive functioning (EF) skills as correlates. Thirty-nine poor readers in Chinese (PC), 39 poor readers in English (PE), and 26 poor readers of both languages (PB) were compared to 39 average readers who…

The study sought to understand the general trajectory of children's executive function, as well as whether there was heterogeneity among monolingual English-speaking and dual language learning children in their growth of executive function. In addition, the study examined whether monolingual English-speaking and dual language learning children…

This study investigates the relationship among working memory (WM), mathematics, and language, with the aim of understanding: (1) whether the functions and capacities of WM components can predict achievement in language and mathematics; and (2) whether competence in the first language (L1) and achievement in mathematics can predict success in…

The present study compared bilingualism with bidialectalism in their respective impact on executive control, using a short-term language switching training paradigm for participants who were both bidialectals (Shanghainese-Mandarin Chinese) and bilinguals (Chinese-English). Twenty participants were assigned to a control group where no language…

Despite frequent reliance on teacher and parent ratings of children's behavior for multi-informant assessment, agreement between teachers' and parents' ratings is low. This study examined the predictive utility of teacher and parent ratings for children's self-regulatory outcomes (i.e., executive function, continuous performance task) in four…

Research Findings: Using two groups of dual language learners (DLLs), the current study examined links between two developmental constructs closely linked to school readiness: the home language environment (HLE) and executive function (EF). In a sample of 90 children (age range = 38-70 months, 59% girls) from either Mexican American (MA, N = 46)…

This study investigated the extent to which individual differences in working memory (WM) mediate the effects of captions with or without textual enhancement on attentional allocation and L2 grammatical development, and whether L2 development is influenced by WM memory in the absence of captions. We employed a pretest-posttest-delayed posttest…

Purpose: There is conflicting evidence regarding effects of bilingualism on inhibition, and the mechanisms that might underlie the effects remain unclear. A prominent account views additional demands on structural language use in bilinguals as being at the root of bilingual effects on inhibition. In this study, we tested the novel hypothesis that…

Language switch costs have been explored less in receptive tasks than in productive tasks, and previous studies have produced mixed findings with regard to switch cost symmetry and the relationship of switch costs to executive function. To address these unresolved gaps, one hundred Chinese-English bilingual adults completed a bilingual lexical…

Recent studies have proposed developments to the Simple View of Reading to reflect reading development across age groups and differences among learner profiles and account for additional factors that explain reading comprehension performance beyond word recognition and language comprehension. One of these proposals is the inclusion of cognitive…

This study investigated the relationship between balanced multilingualism and working memory. Specifically, it reports on the relationship between balanced proficiency in speaking, reading and comprehension (across three languages), and verbal and visuospatial working memory in young South African adults. Information about participants' language…

Purpose: This study examined bilinguals' performance on functional executive function map tasks such as the Zoo Map from the Behavioural Assessment of the Dysexecutive Syndrome and the extent to which working memory, set-shifting, and inhibition measures predicted bilinguals' performance on these tasks. Additionally, we explored the utility of…

According to some accounts, the bilingual advantage is most pronounced in the domain of executive attention rather than inhibition and should therefore be more easily detected in conflict adaptation paradigms than in simple interference paradigms. We tested this idea using two conflict adaptation paradigms, one that elicits a list-wide…

The present study investigated the longitudinal effects of early exposure to L2-English on L1-Turkish language competence, narrative skills and executive functioning. We asked whether early immersion-like exposure to L2, starting around 3 years of age, would have reflections on L1 competence, L1 narrative skills and gains in cognitive flexibility.…

This study examined the concurrent relations of English (EL) and heritage language (HL) proficiency to executive functions (EF) among low-income dual language learners (DLLs) from immigrant families. In a sample of 90 children (age = 38-70 months) from Chinese-speaking Chinese American and Spanish-speaking Mexican American families recruited from…
