This study investigated the feasibility of a vocabulary-based teacher intervention to increase preschool teachers' production of complement clauses (e.g. "I wonder if we can put the monkey in the tree") in teacher-children play interactions. Using a multiple baseline across participants design we measured the impact of an intervention…

This study was designed to examine the strength of question types to obligate complete responses from children, and the effect of age and play context. Participants were typically developing children (mean ages 2;8, 3;4 and 4;7), who engaged in play with three speech-language pathologists in play contexts. Questions posed to the children were…

In this pilot study, we examine the suitability of materials for a vocabulary intervention designed to influence the amount of complex syntax teachers use in at-risk preschool classrooms. Six Head Start classrooms were assigned to one of two vocabulary interventions: a condition using cognitive verbs, which are biased toward complex syntax (e.g.…

Children with hearing impairment (HI) are at an increased risk of developing speech and language problems similar to those of children with developmental language disorder (DLD), including difficulties with phonology and grammar. This study investigated similarities and differences in phonological and grammatical production between children with…

Although many children are referred with difficulties in both their speech and their language, the literature offers relatively little guidance on their therapy.
