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…

Our main objective was to analyze the role of imageability in relation to the age of acquisition (AoA) of nouns and verbs in Spanish-speaking children with Down syndrome (DS) and their peers with typical development (TD). The AoA of nouns and verbs was determined using the MacArthur-Bates CDIs adapted to the profile of children with DS. The AoA…

While socioeconomic disparities in the home language environment have been well established, the mechanisms explaining these disparities are poorly understood. One plausible mechanism is heightened stress. The current study investigated whether maternal perceived stress was 1) associated with measures of the home language environment, and 2)…

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…

Background: This study explores how family language policies (FLPs) in multilingual homes where isiXhosa is the primary language influence caregiver choices regarding children's language development and education. Objectives: The study aims to give insight on how non-nuclear family structures in a selected sample of Western Cape families are…

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.…

The association between decontextualized talk (DT; i.e., talk extending beyond immediate context) and child language outcomes is well-attested but not well-understood. This study tested the hypothesis that DT is more linguistically complex than contextualized talk (CT). Thirty-eight Norwegian children (M[subscript age] = 5.5 years; 25 girls; 30…

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…

Person-referring pronouns in the first and second person (I, your) have been viewed as signs of increasing social understanding in children due to their shifting reference properties. However, they are linguistically complex elements and might depend on general language development. We used longitudinal transcript data from Manchester corpus (12…

This article presents a developmental pathway for the acquisition of morphosyntactic variation. Although there is abundant evidence that morphosyntactic variation is pervasive among adults, much less is known about how children acquire such variation. The literature thus far indicates that the pathway of development involves first producing only…

Purpose: The purpose of the present study was to examine whether there is a listening preference for child-directed speech (CDS) over backward speech in moderate-preterm infants (MPIs). Method: Eighteen MPIs of gestational age of 32.0 weeks (range: 32-34.06 weeks), chronological age of 8.09 months, and maturation age of 6.48 months served as the…

This article examines multilingual language use in two groups of children, one group at a state school, and one at a private IB school. The IB school has earlier been assumed to reflect an 'elite' multilingualism. Three research questions are posed: to what extent is the children's language use multilingual, what are their typological profiles,…

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…

This article explores the applicability of mean length of utterance (MLU) as a language assessment measure for Georgian child language, as to-date, Georgian, a morphologically rich language with numerous inflectional categories, experiences an extensive lack of instruments for early language assessment. To this end, a set of guidelines for…
