Words that describe sensory perception give insight into how language mediates human experience, and the acquisition of these words is one way to examine how we learn to categorize and communicate sensation. We examine the differential predictions of the typological prevalence hypothesis and embodiment hypothesis regarding the acquisition of…

Children with delays in expressive language (late talkers) have heterogeneous developmental trajectories. Some are late bloomers who eventually "catch-up," but others have persisting delays or are later diagnosed with developmental language disorder (DLD). Early in development it is unclear which children will belong to which group. We…

Communication is best understood as occurring along three dimensions: interactional, conceptual, and linguistic. However, few studies have examined early parent-child communication along all three dimensions simultaneously. This study examines these three dimensions of communication in Norwegian parent-child interactions during play. Thirty-nine…

Linguistic interactions between parents and their children are frequently studied to investigate how children acquire language. From observations, researchers have identified interaction strategies that foster children's language development. In turn, interventions to support children's early language skills employ styles of interaction derived…

This is the first large-scale study of resources as a form of "language management" -- that is, a way of influencing children's language practices. We introduce the distinction between child-directed resources (i.e. those providing parents with opportunities to engage with their children in the languages they are transmitting) and…

Research Findings: Reading e-books is becoming common even among toddlers, but we have limited understanding of how parents-toddlers reading e-books together compares to print books. To address the gap, we investigated interactions of 30 mother-toddler (12 months) dyads, in particular, mothers' language use, while reading both electronic and print…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

This study investigates whether the earliest words children choose to say are mainly words containing sounds they can produce (cf. 'phonological dominance' hypotheses), or whether children choose words without regard to their phonological characteristics (cf. 'lexical dominance' hypotheses). Phonological properties of words in spontaneous speech…

Early trilingual development is an excellent testing ground for input reduction effects on acquisition outcomes. This article reports a study investigating input-outcome relations in a child Leo in Hong Kong, who was addressed to in Mandarin, Cantonese and later also in English by caretakers through 'one caretaker-one language' and 'one day-one…

In this study, the relationship between play, language skills and social competence is explored in a sample (n = 1005) of 33-month-old toddlers in a Norwegian early childhood education setting--Barnehages--based on two observational materials ("Tras" and "Alle med"). The study has two aims: (1) to investigate whether there is a…

This study examined the quantity and quality of parental linguistic input to toddlers with moderate hearing loss (MHL) compared with toddlers with normal hearing (NH). The linguistic input to eighteen toddlers with MHL and twenty-four toddlers with NH was examined during a 10-minute free-play activity in their home environment. Results showed that…

For adults, "no" and "not" change the truth-value of sentences they compose with. To investigate children's emerging understanding of these words, an experimenter hid a ball in a bucket or a truck, then gave an affirmative or negative clue (Experiment 1: "It's not in the bucket"; Experiment 2: "Is it in the…

The expressive lexical skills of 53 Polish bilinguals aged 24-36 months living in the UK and Ireland were assessed using Polish and British English adaptations of the MacArthur-Bates Communicative Development Inventories. Polish vocabulary scores were compared to those of 53 Polish monolinguals matched for age, gender and parental education. The…

Adult responsiveness is related to language development both in young typically developing children and in children with autism spectrum disorders, such that parents who use more responsive language with their children have children who develop better language skills over time. This study used a micro-analytic technique to examine how two facets…

Lexical development in first language (L1) Turkish and second language (L2) German in two- to three-year-old children was examined, using parental vocabulary checklists in Turkish and in German. Children showed strong Turkish dominance in the number of lexical items they produced, which was due to the more frequent exposure to Turkish and higher…
