Early vocabulary development benefits from diverse lexical exposures within children's language environment. However, the influence of lexical diversity on children as they enter middle childhood and are exposed to multimodal language inputs remains unclear. This study evaluates global and local aspects of lexical diversity in three…

Purpose: The Language ENvironment Analysis (LENA) technology uses automated speech processing (ASP) algorithms to estimate counts such as total adult words and child vocalizations, which helps understand children's early language environment. This ASP has been validated in North American English and other languages in predominantly monolingual…

In low- and middle-income countries, urbanization has spurred the expansion of peri-urban communities, or urban communities of formerly rural residents with low socioeconomic status. The growth of these communities offers researchers an opportunity to measure the associations between the level of urbanization and the home language environment…

The dynamic nature of multilingual families and their language policies has been touched upon by numerous studies. Adding to the field, the present study assesses the stability of family language policy in a standardised and quantitative manner. To this end, a linguistically heterogenous sample consisting of 488 multilingual families raising young…

Purpose: Previously, Lancaster and Camarata (2019) showed that the continuum/spectrum model of the developmental language disorder (DLD) best explained the high heterogeneity of symptoms in children with DLD. We hypothesize that the continuum/spectrum approach can include not only children with DLD but also typically developing (TD) children with…

Infants' preference for vowelharmony (VH, a phonotactic constraint that requires vowels in a word to be featurally similar) is thought to be language-specific: Monolingual infants learning VH languages show a listening preference for VH patterns by 6 months of age, while those learning non-VH languages do not (Gonzalez-Gomez et al., 2019; Van…

This study investigated phonological whole-word measures in bilingual Arabic-English speakers to explore how the target approximations influence children's phonological development. To this end, fifteen bilingual Arabic-English speakers and nine monolingual Arabic-speaking children aged 36-48 months (mean = 42) participated in a parent-child…

Inspired by research in language play and linguistic ethnography, this article examines children's language play in early childhood education and care (ECEC) as a locally situated generic practice created through children's semiotic repertoires. The article is based on video-recorded linguistic ethnographic fieldwork in a Danish day care centre.…

Young learners are known to extend verb regularity further than it actually is. When it happens, this children's overregularization phenomenon can be a result of several reasons: a failed linguistic development due to confusion between rules and memory, a lack of feedback from adults, and problems with cognitive development. The present study…

Children's language development can reflect the developmental process of children's cognition and social emotions. The present study focuses on preschool children's conversational competence and narrative competence, aiming at exploring developmental features of preschool children's pragmatic competence through analyzing data from self-built oral…

Purpose: The Arabic verb system features a nonlinear root and pattern derivational morphology. Previous studies suggest that young Arabic and Hebrew speakers' early verb use is based on semantic complexity rather than derivational morphological structure. The present study examines the role of morphological and semantic complexity in the emergence…

Associative anaphora refers to a discourse operation that links a definite determiner phrase (DP) to an antecedent that acts as an indirect referent of the definite DP. For example, in the sequence 'I bought a laptop. The keyboard was black', the definite DP 'the keyboard' is linked to 'a laptop', meaning 'the keyboard of the laptop'. The…

Purpose: Our study analyzes probabilistic constraints on subject expression previously found in adult Spanish in the speech of typically developing (TD) Spanish-speaking children and children with developmental language disorder (DLD). Previous work shows that children with DLD produce fewer overt subjects than typically developing children, and…

Background: There is a global need for synthetic speech development in multiple languages and dialects, as many children who cannot communicate using their natural voice struggle to find synthetic voices on high-technology devices that match their age, social and linguistic background. Aims: To document multiple stakeholders' perspectives…

In early childhood centres, decontextualised talk is often associated with literacy activities. In this study, however, we investigated toddler-educator conversations across various activities with a focus on those about topics that were not related to the immediate context. We examined the communicative purposes and linguistic features of these…
