A growing body of work suggests that speaker-race influences how infants and toddlers interpret the meanings of words. In two experiments, we explored the role of speaker-race on whether newly learned word-object pairs are generalized to new speakers. Seventy-two 20-month-olds were taught two word-object pairs from a familiar race speaker, and two…

The Yucatec Maya language has a highly complex deictic system with interesting typological differences that in addition to demonstratives and locative adverbs also includes ostensive evidentials and modal adverbs. Given that deictic words are among the first that children produce, the aim of this study is to identify the early acquisition that…

Children need to learn the demands of their native language in the early vocabulary development phase. In this dynamic process, parental multimodal input may shape neurodevelopmental trajectories while also being tailored by child-related factors. Moving beyond typically characterized group profiles, in this article, we synthesize growing evidence…

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…

Background: In typically developing (TD) children, gesture emerges around 9 months of age, allowing children to communicate prior to speech. Due to the important role gesture plays in the early communication of autistic and TD children, various tasks have been used to assess gesture ability. However, few data exist on whether and how tasks…

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…

To learn language, children must map variable input to categories such as phones and words. How do children process variation and distinguish between variable pronunciations ("shoup" for "soup") versus new words? The unique sensory experience of children with cochlear implants, who learn speech through their device's degraded…

Computational cognitive modeling is a tool we can use to evaluate theories of syntactic acquisition. Here, I review several models implementing theories that integrate information from both linguistic and non-linguistic sources to learn different types of syntactic knowledge. Some of these models additionally consider the impact of factors coming…

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 collaborative decision-making, partners compare reasons behind conflicting proposals through meta-talk. We investigated UK-based preschoolers' (mixed socioeconomic status) use of meta-talk (Data collection: 2018-2020). In Study 1, 5- and 7-year-old peer dyads (N = 128, 61 girls) heard conflicting claims about an animal from two informants. One…

The number of U.S. children living in households with extended families has greatly increased in the last 4 decades. This demographic shift calls for a reevaluation of the impact of household size on children's development. Household density (HHD), measured as the ratio of people to bedrooms in a home, has been shown to negatively relate to…

I argue that the variation within and across contexts detailed by Shin & Miller is indicative of a broader phenomenon in which morphosyntax and the discourse context are intertwined, including elements like perspective, discourse relations, information structure, and common ground. Appealing to independent evidence highlighting the role of…

The well-known sampling limitation of most longitudinal corpus data can be even more consequential in the study of morphosyntactic variation in child language. An analysis of caregiver input suggests that variable use in overlapping contexts may be hard to find by solely relying on corpus data collected under the sampling procedures that are…

Joint attention and imitation are thought to facilitate a developmental cascade of language and social communication skills. Delays in developing these skills may affect the quality of children's social interactions and subsequent language development. We examined how responding to joint attention and object imitation skills predicted rate of…
