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…

Purpose: The goal of this study is to examine how shyness affects a child's performance on language assessments that vary in sociability. We hypothesized that accuracy on language tasks would be driven by shyness such that shyer children would perform better on nonsociable tasks compared to sociable tasks. Method: The procedures followed a…

Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

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…

Purpose: Place and manner of articulation in American English-learning children's salient consonant-vowel-consonant-vowel (C[subscript 1]VC[subscript 2]V) target words (e.g., "baby," "bunny," and "cookie") were compared with their actual productions of these words. We hypothesized that target words with repeated place…

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…

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…

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…

The current study used a multiple baseline across behaviors design to evaluate a rapid coaching intervention for teaching two caregivers to implement naturalistic language interventions (NLIs) with their child with autism. Coaches were preservice behavior analysts completing a personnel preparation program in applied behavior analysis who…

The aim of the present study was to investigate the acquisition of ditransitive structures beyond production. We conducted an elicitation task (production) and a picture-sentence matching task measuring accuracy and response times (comprehension). We examined German five-to seven-year-old typically developing children and an adult control group.…

Oral language is the primary means through which a child controls, describes, organises, and evaluates their life experiences and their ability to use oral language which effectively impacts their future literacy development. Currently, the world is awash with dynamic change and constant disruption. These include natural disasters such as the…

Having heard "a pimwit", English-speakers assume that "the pimwit" is also possible. This type of productivity is attributed to syntactic categories such as NOUN and DETERMINER, but the key question is "how" do humans become endowed with these categories in the first place. We propose a novel approach that combines…

This article focuses on complex predicates in Qaqet, a Papuan (Baining) language of Papua New Guinea, spoken by 15,000 people and still being acquired monolingually in remote areas. A large part of the Qaqet verb lexicon is compositional, consisting of simple verb roots that combine with prepositions or particles/suffixes, jointly contributing to…

Children's developing understanding of language may influence their ability to accurately respond to questions inquiring about their event knowledge (i.e., Why and How Come questions), potentially creating misinterpretations in adult-child communication. The present study examined 120 5-, 7-, and 9-year-old's accuracy in responding to Why and How…
