Presenting pictures of faces side by side is a common paradigm to assess infants' attentional biases according to social categories, such as gender, race, and language. However, seeing static faces does not represent infants' typical experience of the social world, which involves people in motion and performing actions. Here, we assessed infants'…

Previous studies found that bilingual children and adults with typical language development (TLD) perform better than monolinguals in novel word learning, but show lower scores on lexical retrieval tasks (e.g., naming known words). Children with developmental language disorder (DLD) lack in their abilities in both tasks compared with children with…

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…

Language and accent strongly influence the formation of social groups. By five years of age, children already show strong social preferences for peers who speak their native language with a familiar accent (Kinzler, Shutts, DeJesus, & Spelke, 2009). However, little is known about the factors that modulate the strength and direction of…

A central question in the field of foreign language acquisition is whether the processes involved in reading development in a foreign language are universal or dependent on characteristics of the specific language involved. We investigated the impact of orthographic depth and writing system on word reading acquisition in a foreign orthography, by…

Academic language has been shown to significantly contribute to success across school subjects. However, to date, there are no empirical studies addressing its development across primary school age. The present study investigated the growth of academic vocabulary and influential conditions from Grades 2 to 4 based on a newly developed and…

The present study investigated the contribution of morphological and cognate awareness to the development of English and French vocabulary knowledge among young minority and majority language children who were enrolled in a French immersion program. Participating children (n = 75) were assessed in English and French on measures of morphological…

Little is known about 2nd language development among young, low-income, language-minority children. This article examined the longitudinal English development of low-income, dual language learners (DLLs) in Miami ("n" = 18,532) from kindergarten through 5th grade. Growth curve modeling indicated that social skills, good behavior, Spanish…

This twin study examined the relative contributions of genes and environment on 2nd language reading acquisition of Chinese-speaking children learning English. We examined whether specific skills-visual word recognition, receptive vocabulary, phonological awareness, phonological memory, and speech discrimination-in the 1st and 2nd languages have…

A 4-stage developmental model, in which auditory sensitivity is fully mediated by speech perception at both the segmental and suprasegmental levels, which are further related to word reading through their associations with phonological awareness, rapid automatized naming, verbal short-term memory and morphological awareness, was tested with…
