Forty-two adolescents with Down syndrome (DS) ages 10 to 21 years completed a battery of language and phonological memory measures twice, 2 years apart. Individual differences were highly stable across two years. Receptive vocabulary scores improved, there was no change in receptive or expressive grammar scores, and nonword repetition scores…

The purpose of this cluster randomized group study was to investigate the effect of multitiered, dual language instruction on children's oral language skills, including vocabulary, narrative retell, receptive and expressive language, and listening comprehension. Participants were 3-5 year old children (n = 81) who were learning English and whose…

Purpose: This study investigated the early rule-based sentence productions of 3- and 4-year-old children with severe speech disorders who used single-meaning graphic symbols to communicate. Method: Ten 3- and 4-year-olds requiring the use of augmentative and alternative communication, who had largely intact receptive language skills, received…

Children with Developmental Language Disorder are likely to experience difficulties with morphosyntax, especially regular past tense marking. Few studies have evaluated the effectiveness of intervention to improve morphosyntax in young school-aged children with DLD. This study investigated the efficacy of combined explicit and implicit…

Purpose: This study was conducted to evaluate the effects of a conversation-based intervention on the expressive vocabulary and grammatical skills of children with severe motor speech disorders and expressive language delay who use augmentative and alternative communication. Method: Eight children aged from 8 to 13 years participated in the study.…

This article summarizes the evidence as regards the effectiveness of therapy for grammar for school-aged children with language impairments. I first review studies focusing on specific areas of grammar (both expressive and receptive targets) and then studies aiming to improve language more generally, several of which focus more on the…

Purpose: To determine whether (a) expressive grammar intervention facilitated social and emergent literacy outcomes better than no intervention and (b) expressive grammar gains and/or initial expressive grammar level predicted social and emergent literacy outcomes. Method: This investigation was a follow-up to a recently published study exploring…

This study taught the passive to two children with specific language impairment (aged 8;1 and 8;2). It employed usage-based principles including "constructional grounding"; using short structures as the basis for acquiring long structures, and "construction conspiracy"; encouraging analogies between partially overlapping…

Background: Children with specific language impairment are known to struggle with expressive grammar. While some studies have shown successful intervention under laboratory conditions, there is a paucity of evidence for the effectiveness of grammar treatment in young children in community settings. Aim: To evaluate the effectiveness of a…

This article describes the construction of a procedure for dynamic assessment of the expressive grammar of children already identified with language impairments. Few instruments exist for the dynamic assessment of language, and those that have been developed have been largely used to successfully differentiate language impaired from culturally…

Background: Clinical services in the UK are increasingly delivering "consultative" methods of intervention rather than "direct" intensive input for children with receptive and expressive language difficulties, yet there has been little systematic evaluation of these different intervention models. Aims: To investigate the…

Children with Down syndrome often display speech-comprehensibility and grammatical deficits beyond what would be predicted based upon general mental age. Historically, speech-comprehensibility has often been treated using traditional articulation therapy and oral-motor training so there may be little or no coordination of grammatical and…

This study, involving 26 children (ages 44-70 months) with impairments in grammar and phonology, found that children receiving either a clinician-administered or parent-administered intervention showed gains in expressive grammar, but there were no indirect effects on subjects' phonological production. Language intervention approaches for young…

Three case studies are reported, illustrating use of Structured Role Play Therapy in teaching moderately language-delayed children, aged 4-6, to produce specifically targeted grammatical forms and to generalize production to sentences not included in therapy activities. The role-playing resulted in rapid increases in production accuracy of…

This study compared the relative effectiveness of imitative intervention and conversational recast language intervention applied to grammatical morpheme and complex sentences in 21 children with specific language impairment. The conversational procedure was found to require fewer presentations to first spontaneous use and to produce more…
