Early research that relied on standardized assessments of intelligence reported negative effects of bilingualism for children, but a study by Peal and Lambert (1962) reported better performance by bilingual than monolingual children on verbal and nonverbal intelligence tests. This outcome led to the view that bilingualism was a positive…

In contrast to research that examines the effects of socioeconomic status (SES) and bilingualism on development by comparing clearly disparate groups, the present study investigated the role of subtle differences in these experiences for their joint impact on performance on a verbal fluency task and an executive function (EF) task. The study…

Previous research has shown that cognitive development is sensitive to socio-economic status (SES) and multilinguistic experiences. However, these effects are difficult to disentangle and SES may modulate the effects of multilingualism. The present study used data from a large cohort of pupils who took part in the Study of Cognition, Adolescents…

Purpose: The current study examined the role of attention and language ability in nonverbal rule induction performance in a demographically diverse sample of school-age children. Method: The participants included 43 English-speaking monolingual and 65 Spanish-English bilingual children between the ages of 5 and 9 years. Core Language Index…

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…

There is currently much controversy surrounding the cognitive advantages that are often associated with bilingualism, especially regarding the so-called executive control advantage. Recently, it has been suggested that bilingualism emerging from immersion education may not lead to an advantage in executive control, but rather to an improvement…

Children with autism often display discrepancies in their intellectual functioning, with nonverbal skills frequently being more developed than verbal. Compared to monolingual autistic children, however, much less is known about how bilingualism affects intelligence in autism. The current study examined the intelligence profiles of 146 bilingual…

Effects of child and environmental factors in moderating the course of bilingual development were investigated using longitudinal data, from age 2.5 to 5 years, on 126 U.S.-born children with early exposure to Spanish and English. Multilevel models of Spanish and English expressive vocabulary identified children's phonological memory ability as a…

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 from language minority homes reach school age with variable dual language skills. Cluster analysis identified four bilingual profiles among 126 U.S.-born, 5-year-old Spanish-English bilinguals. The profiles differed on two dimensions: language balance and total language knowledge. Balance varied primarily as a function of indicators of…

Background & Aims: Given that standardized language measures alone are inadequate for identifying functionally defined developmental language disorder (fDLD), this study investigated whether non-linguistic cognitive abilities (procedural learning, motor functions, executive attention, processing speed) can increase the prediction accuracy of…

Purpose: This study investigates the interaction of language ability status, cultural experience, and nonverbal cognitive skill performance in Spanish-English bilinguals with typical development (TD) and developmental language disorder (DLD). Method: One hundred sixty-nine Spanish-English bilingual kindergartener's scores on the Symbolic Memory…

Most research reporting that bilingual children exhibit enhanced cognitive skills and social awareness relative to their monolingual peers focusses on children raised and educated bilingually, making it difficult to pinpoint the degree of second language exposure necessary for such advantages to materialise. The current study measures the social…

Purpose: The purpose of this study was to examine differences in performance between monolingual and Spanish-English bilingual second graders (aged 7-9 years old) on executive function tasks assessing inhibition, shifting, and updating to contribute more evidence to the ongoing debate about a potential bilingual executive function advantage.…

A growing body of cross-linguistic research has suggested that morphological awareness plays a key role in both L1 and L2 word reading among bilingual readers. However, little is known about the interaction and development of L1 and L2 morphological awareness in relation to word reading. We addressed this issue by evaluating the unique…
