For generations the study of vocal development and its role in language has been conducted laboriously, with human transcribers and analysts coding and taking measurements from small recorded samples. Our research illustrates a method to obtain measures of early speech development through automated analysis of massive quantities of day-long audio recordings(More)
Down syndrome (DS) is associated with abnormalities in multiple organ systems and a characteristic phenotype that includes numerous behavioral features. Language, however, is among the most impaired domains of functioning in DS and, perhaps, also the greatest barrier to independent meaningful inclusion in the community. In this article, we review what is(More)
Research over the past 50 years has yielded several promising approaches and many specific intervention techniques designed to enhance the communication and language development of young children with intellectual and developmental delays and disabilities. Yet virtually no systematic research has been conducted on the effects of different treatment(More)
This study tested the effect of a method of facilitating prelinguistic communication on parents' responsivity and children's communication and productive language development. The method involved Responsivity education for the parents and Prelinguistic Milieu Teaching for the children (RPMT). Thirty-nine prelinguistic toddlers with intellectual disabilities(More)
PURPOSE To evaluate the efficacy of a 6-month course of responsivity education/prelinguistic milieu teaching (RE/PMT) for children with developmental delay and RE/PMT's effects on parenting stress in a randomized clinical trial. METHOD Fifty-one children, age 24-33 months, with no more than 10 expressive words or signs, were randomly assigned to(More)
PURPOSE The authors sought to determine whether a program of 5 weekly doses of milieu communication teaching (MCT) would yield improvements in children's communication and word use compared with a once-weekly delivery of the same treatment. METHOD Sixty-four children with intellectual and communication delay were randomly assigned to receive 60-min(More)
The relationship between early maternal responsivity and later child communication outcomes in young children with fragile X syndrome was investigated. Data were obtained from 55 mother-child dyads over a 36-month period. Performance data were obtained at each measurement point from video observations of four different contexts. These were coded for (a)(More)
There is growing evidence that cumulative exposure to highly responsive parenting styles throughout the early childhood period may provide a variety of important child benefits in terms of language, cognitive, social, and emotional development. We view maternal responsivity as a dynamic construct of central importance to the development of children with(More)
BACKGROUND AND OBJECTIVES Although home visiting programs have been documented to improve parenting in high-risk families, their effectiveness is diminished when parents disengage from programs. Cellular phones offer an approach to promoting parent engagement and enhancing parenting outcomes. Our objective was to examine whether mothers in a parenting(More)
This paper tests whether two prelinguistic communication interventions have a differential effect on productive and receptive language development 6 and 12 months after the end of treatment. We predicted that treatment effects on language development would vary as a function of pretreatment maternal responsivity or amount of mothers' formal education.(More)
