Despite earlier claims that language abilities are intact in individuals with Williams syndrome (WS), many studies have shown that language development is often delayed and atypical, that is, it develops in line with different cognitive abilities compared to typically developing populations. It is unclear, however, whether general cognitive…

Emotion words allow us to identify, describe and regulate our emotional states. Emotion vocabulary grows through childhood, but little research has considered emotion words in the context of children's written language. To address this gap, we used a cross-corpus developmental approach to chart the emergence of emotion words in children's reading…

Shared intentionality theory posits that at age 3, children expand their conception of plural agency to include 3- or more-person groups. We sought to determine whether this conceptual shift is detectable in children's pronoun use. We report the results of a series of Bayesian hierarchical generative models fitted to 479 English-speaking…

This study investigated the complex relationship between false-belief (FB) understanding, structural language and pragmatic communication in typically developing children. A total of 78 Finnish children, aged from 4 to 6 years, including an equal number of boys and girls, participated in this study. In the first instance, the study explored the…

Research suggests that girls acquire language faster than boys, with gender differences most pronounced in vocabulary acquisition during early childhood. This study examines the role of gender in the acquisition of vocabulary and morphosyntax in Palestinian Arabic-speaking children aged 18 to 36 months. Using the Palestinian Arabic Communicative…

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…

This study examines whether children acquiring Tseltal (Mayan) demonstrate a noun bias -- an overrepresentation of nouns in their early vocabularies. Nouns, specifically concrete and animate nouns, are argued to universally predominate in children's early vocabularies because their referents are naturally available as bounded concepts to which…

Shared book reading in preschool settings plays an influential role in supporting children's oral language and emergent literacy skills. Early childhood teachers can provide high-quality shared book reading experiences using extratextual utterances (reading beyond the story text) to maximise these learning outcomes. We report on the development…

Child-directed speech has long been known to influence children's vocabulary learning. However, while we know that caregiver utterances differ from those directed at adults in various ways, little is known about any differences in the lexical properties of child-directed and adult-directed utterances. We compare over half a million word tokens…

A growing body of research suggests that fine motor skills (FMS) are associated with language development. In this study, we examined 76 children aged 3-6 years assessing the link between language and FMS. Specific measures included receptive and expressive vocabulary, oral narrative skills, and various fine motor tasks. Hierarchical linear…

Vocabulary size is a crucial early indicator of language development, for both monolingual and bilingual children. Assessing vocabulary in bilingual children is complex because they learn words in two languages, and there remains significant controversy about how to best measure their vocabulary size, especially in relation to monolinguals. This…

Children's speech is influenced by the speech they hear, in particular by the parental speech addressed directly to them. The aim of this study was to analyse toddlers' speech with their parents and to investigate the influence of specific characteristics of child-directed speech on child speech in real time during mother-child and father-child…

This exploratory study evaluates the effectiveness of an online instructional vocabulary module in enhancing parents' understanding of early childhood vocabulary development and how to demonstrate this in a home environment. Forty-one parents viewed the vocabulary video and completed pre- and post-surveys. While most parents could define…

Mind-mindedness (MM), the parent's propensity to treat their young child as an individual with a mind of their own, has repeatedly been found to be positively associated with subsequent child development outcomes. In the current Swedish study, the first aim was to investigate the main features of MM in this cultural context and the second aim was…

Toddlers with smaller vocabulary than expected for their age are considered late talkers (LT). This study explored the effects of characteristics of words on vocabulary acquisition of 12- to 24-month-old LT children compared with an age matched (AM) and a vocabulary matched (VM) group of typically developing peers. Using the…
