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 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…

This study investigates the speech rate of Cypriot Greek-speaking children with developmental language disorder (DLD) as well as the effect of age and gender. The participants were 16 children with DLD ages 4 years 11 months to 8 years 1 month and 22 children with typical language development (TLD) ages 4 years 5 months to 8 years 7 months. Both…

Background: Language exposure is known to be a key factor influencing bilingual vocabulary development in typically developing (TD) children. There is, however, a lack of knowledge in terms of exposure effects in children with developmental language disorder (DLD) and, especially, in interaction with age of onset (AoO) of second language…

Gesture plays an important role in early language development, as how parents respond to their children's gestures may help to facilitate language acquisition. Less is known about whether parental responses facilitate language learning later in childhood and whether responses vary depending on children's language ability. This study explored…

In the current study, we describe a study of the Internet-based Parent-implemented Communication Strategies-Storybook (i-PiCSS). I-PiCSS is an intervention program designed to train and coach parents to use evidence-based naturalistic communication teaching (NCT) strategies (i.e., modeling, mand-model, and time delay) and reading techniques while…

Purpose: Complexity-based approaches to treatment have been gaining popularity in domains such as phonology and aphasia but have not yet been tested in child morphological acquisition. In this study, we examined whether beginning treatment with easier-to-inflect (easy first) or harder-to-inflect (hard first) verbs led to greater progress in the…

Self-injurious behavior (SIB) is a chronic disorder that often begins in early childhood; however, few studies have examined the onset of SIB in young children. This preliminary study reports on the identification, assessment, and observation of SIB in 32 children who had begun to engage in SIB within the previous 6 months. Participants were under…

Demonstrates that young autistic children suffer from deficits in social understanding and symbolic representations of other individuals. Data suggest that the core deficit appears to lie at the intersection of representational abilities and social experiences. (RWB)

This sequential analysis tested the relative extent to which several adult utterance types elicited conversational replies from eight developmentally delayed children (mean age 53 months). Among findings were that child replies of any length were elicited by adult topic continuations more than by any other adult utterance type. (Author/DB)

Reviews past and present research on early communication and language intervention at the Kennedy Center for Research on Human Development, presenting three premises that inform most of the Kennedy Center's research on the issue, summarizing seven lines of contemporary research by Kennedy Center investigators that influence the development of…
