Recent studies have suggested that language aptitude is a domain-general and flexible trait to acquire foreign languages, regarding various cognitive abilities such as memory systems as its crucial components. Despite a growing interest in working memory, however, much remains unknown about the impact of associative memory on language aptitude.…

Research suggests that bilinguals often have weaker vocabulary in their second language compared to that of monolinguals (e.g., Hoff, 2013). It is thus important to identify factors that may facilitate vocabulary learning for bilinguals. One suggested factor is the presence of orthography while learning new oral vocabulary. The current study aims…

Morphological knowledge is known to be positively associated with reading ability. However, whether morphological knowledge affects children's learning of new orthographic representations is less clear. Purpose: This study aimed to investigate morphological effects on orthographic learning in English, and whether this effect, if any, is different…

Language can alter our mental conceptions of space, time, and categories. While there is compelling evidence that thought can be shaped by syntactic, morphological, and lexical features of a language, less is known about the impact of phonology on thought. This dissertation uses novel objects (alien cartoon figures) and pseudoword names in three…

Current models of the affinity between syntax and vocabulary are complex and recognize the contribution of bootstrapping and computational processes. To date, the mutual facilitation between these two constructs over time has not been studied in second language (L2) school children. The present study investigated longitudinally the direction and…

This study investigated bilingualism effects on the production of focus in 5- to 9-year-old Cantonese-English bilingual autistic children's L1 Cantonese, compared to their monolingual autistic peers as well as monolingual and bilingual typically developing children matched in nonverbal IQ, working memory, receptive vocabulary and maternal…

Macaro has stated that the choice between a monolingual, immersive, target language-only pedagogy versus a non-immersive, multilingual pedagogy is 'probably the most fundamental question facing second language acquisition (SLA) researchers, language teachers, and policymakers'. Recognizing that prior empirical work on monolingual versus…

Effective vocabulary interventions for children with hearing loss, including children who are bilingual, are needed because of persistent vocabulary deficits in this population. Current instructional practices for children with hearing loss who are bilingual vary in the degree to which they incorporate the language the child uses at home.…

Word knowledge and the speed of word processing in monolingual children and adults are influenced by word properties, such as the age of acquisition (AoA), imageability, and frequency. Understanding how different properties of words contribute to the ease of processing by bilingual children is a critical step for establishing models of childhood…

This study investigated the vocabulary development of children (N = 547) from linguistically and socioeconomically diverse classrooms in Germany from age 3 in preschool to age 7 in Grade 1. The results showed that for dual language learners (DLLs, n = 107) growth rates in their German majority language skills varied over classrooms. Compared to…

The current study examined the effect of speaker variability on children's cross-situational word learning (XSWL). The study also examined the role of bilingual experience and sustained attention. Forty English monolingual children and 40 Spanish-English bilingual children ages 4-7 completed a XSWL task in a Single Speaker Condition and a Multiple…

This article synthesizes the roles of morphology in English reading acquisition and reports a meta-analytic structural equation modeling study (k = 107, N = 21,818) that tested the effects of morphological awareness (MA) on reading comprehension in school-aged readers. Moderator analysis was conducted through a set of subgroup comparisons based on…

Children who speak one language at home and a different language at school may be at higher risk of falling behind in their academic achievement when schooling is disrupted. The present study examined the effects of COVID-19-related school disruptions on English language and literacy development among monolingual and bilingual children in the US.…

Bilingual children with a limited command of the second language (L2) often yield unsatisfactory results in L2-based non-word repetition tasks (NWRT) for the assessment of working memory. In this study, monolinguals (MO) and bilinguals (BI) of preschool age acquiring German were compared in regard to their performance on German-based NWRT to…

Background: The educational context in South Africa does not always support the development of bilingualism to enable the cognitive and social advantages of dual language proficiency. The emphasis on English as the language of instruction overlooks bilingual competence. This study attempts to show that by considering conceptual vocabulary,…
