There is considerable controversy over the factors that shape infants' developing knowledge of grammar. Work with artificial languages suggests that infants' ability to track statistical regularities within the speech they hear could, in principle, support grammatical development. However, little work has tested whether infants' performance on…

Children with Down syndrome (DS) present language deficits in all linguistic domains and their language development lags behind that of typically developing children. However, their receptive language skills appear to be better than their productive in all linguistic domains. Research on bilingual children with DS is limited, but has shown that…

Bilingual children demonstrate varying levels of proficiency in each of the two languages to which they are exposed. Even though it is widely acknowledged that bilingual children are not a homogenous group, existing studies on dual-language profiles in bilingual children have focused on expressive language profiles. In this study, we used the…

The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages…

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are…

The purpose of the present study was to examine how foreign language education may affect preschool children's native language development. The study was carried out with 70 children who were 48-60 months-old and attending a public preschool in Alanya, a district of Antalya, in Turkey. The research method of the study was Solomon Four-Group…

Before infants produce words, they can discriminate changes in motion event components such as manner (how an action is performed) and path (trajectory of an action). Individual differences in nonlinguistic event categorization are related to children's later verb comprehension (Konishi, Stahl, Golinkoff, & Hirsh-Pasek, 2016). We asked: (a) Do…

The current study examines the relationship between bilingual children's dual language experience (i.e. language input, language output and vocabulary proficiency), and their social-emotional and behavioral skills. Data were analysed from 805 Singaporean bilingual preschoolers (ages 4; 1-5; 8 years), who are learning English and either Mandarin (n…

This article reports results from a longitudinal study from age 4 to 7 of comprehension and production of narrative macrostructure in Swedish monolingual children (N = 17). "Baby Birds/Baby Goats" from the Multilingual Assessment Instrument for Narratives (LITMUS-MAIN) were used to elicit narratives and ask comprehension questions at age…

Literacy is a powerful tool against poverty, leading to further education and vocational success. In sub-Saharan Africa, schoolchildren commonly learn in two languages--African and European. Multiple early literacy skills (including phonological awareness and receptive language) support literacy acquisition, but this has yet to be empirically…

This study employs the Specificity Principle to examine the relative impacts of external (input quantity at home and at school, number of books and reading frequency at home, teachers' degree and experience, language usage, socioeconomic status) and internal factors (children's working memory, nonverbal intelligence, learning-related…

There is a need to provide bilingual assessments and reference data to identify those who struggle to acquire their heritage language (L1) or the language spoken in the country of residence (L2). However, bilingual assessments and data are still sparse. Therefore, the aim was to use a tablet application to screen receptive vocabulary in different…

The purpose of this study was to examine the fast mapping skills in Spanish-English bilingual preschool children in two learning contexts: storybook reading and cartoon viewing. Eighteen typically developing Spanish-English bilingual preschool children completed a fast mapping task in Spanish (L1) and in English (L2). In 4 different sessions, each…

In many low- and middle-income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a country's official language(s). Thus, assessments of children before school age, conducted in a nation's official language, may not fully reflect a…

Previous research has shown that learners of English as a second language have difficulties in understanding connected speech spoken by native English speakers. This study examines the role of the perception of reduced forms (e.g., contraction, elision, assimilation) of English words in connected speech comprehension and the phonological skills…
