Background: Language interventions are complex behavioural interventions, making it difficult to distinguish the specific factors contributing to efficacy. The efficacy of oral language comprehension interventions varies greatly, but the reasons for this have received little attention. Aims: The aim of this meta-analysis was to examine which…

Background: Standardised Mandarin assessment tools for examining difficulties in language comprehension and expression at different developmental stages are limited in China. The first comprehensive standardised Mandarin assessment tool is the Diagnostic Receptive and Expressive Assessment of Mandarin-Comprehensive (DREAM-C), which is normed for…

Purpose: This study compares the home language environments of children with (a suspicion of) developmental language disorder (DLD) with that of children with typical development (TD). It does so by adopting new technology that automatically provides metrics about children's language environment (Language ENvironment Analysis [LENA]). In addition,…

Purpose: The primary aim of the study was to examine the association between early childhood practitioners' use of language facilitation strategies during interactive book reading of informational texts related to science and the language skills of preschool children with developmental language disorder (DLD). Method: Twenty-four practitioners (12…

Purpose: This study explores whether the quality of parent-child interaction is associated with language abilities cross-sectionally and longitudinally up to preschool-age among children with developmental language disorder (DLD). Method: Participants were 97 monolingual children with DLD and their parents from the Helsinki Longitudinal SLI study,…

Background: In 2016/17, the CATALISE Consortium published the results of a multinational and multidisciplinary Delphi consensus study, representing agreement among professionals about the definition and process of identification of children with Developmental Language Disorder (DLD) (Bishop et al., 2016, 2017). The extent to which the current…

Background: Individuals with developmental language disorder or Williams syndrome are reported to use more gestures than individuals with typical development. However, these two groups differ considerably in visuospatial and language skills, two skills that are hypothesized to shape gesture rate. Aims: We first examined whether children with both…

Twenty-eight Albanian-Greek bilingual children with Developmental Language Disorder and 28 children with Autism Spectrum Disorder but no language impairment, along with 28 typically-developing, age-, Performance IQ- and socioeconomic status-matched bilingual children were asked to produce two expository texts which were coded for spelling…

Purpose: Cognates, words in two languages that share form and meaning, can be used to support vocabulary development in bilingual children. Typically developing bilinguals have shown better performance on cognates versus noncognates. Of key interest is whether bilinguals with developmental language disorder (DLD) also show a cognate effect and, if…

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…

Background: There is empirical evidence that a developmental language disorder (DLD) in early childhood leads to behaviour problems. However, it is still not clear how changes in language proficiency in these children influence the presence of behaviour problems. Aims: The aim of this study is to examine if changes in language proficiency are…

Purpose: This study investigated the production of tense and subject-verb agreement in Palestinian Arabic-speaking children with developmental language disorder (DLD) in comparison to their typically developing (TD) peers in terms of (a) performance accuracy and (b) error patterns. Method: Participants were 14 children with DLD aged 4;0-7;10 and…

Predictors of expressive grammar were compared in formal and naturalistic assessment tasks for children with typically developing (TD) language and with Developmental Langauge Disorder (DLD). Standardized expressive language assessments were administered to 110 preschoolers. The parents of these children reported whether or not they were concerned…

Background: Early and effective treatment for children with developmental language disorder (DLD) is important. Although a growing body of research shows the effects of interventions at the group level, clinicians observe large individual differences in language growth, and differences in outcomes across language domains. A systematic…

Research has investigated how lexical-semantic and participant factors impact word learning in young children and adults. However, limited information pertaining to expressive vocabulary development exists for school-aged bilinguals--particularly those with developmental language disorder (DLD). Cross-linguistic differences in the semantic…
