This randomized group experiment compared the efficacy of 2 communication interventions (Responsive Education and Prelinguistic Milieu Teaching [RPMT] and the Picture Exchange Communication System [PECS]) in 36 preschoolers with autism spectrum disorders. Each treatment was delivered 3 times per week, in 20-min sessions, for 6 months. The results revealed(More)
PURPOSE This randomized group experiment compared the efficacy of 2 communication interventions (Responsive Education and Prelinguistic Milieu Teaching [RPMT] and the Picture Exchange Communication System [PECS]) on spoken communication in 36 preschoolers with autism spectrum disorders (ASD). METHOD Each treatment was delivered to children for a maximum(More)
In 2002, the National Institutes of Health sponsored a meeting concerning methodological challenges of research in psychosocial interventions in Autism Spectrum Disorders. This paper provides a summary of the presentations and the discussions that occurred during this meeting. Recommendations to federal and private agencies included the need for randomized(More)
Later-born siblings of children with autism spectrum disorder (Sibs-ASD) are at elevated risk for social impairments. Two putative predictors of later social impairment-measures of responding to joint attention and weighted triadic communication-were examined in a sample of 43 Sibs-ASD who were followed from 15 to 34 months of age. Results revealed that(More)
We examined the longitudinal relationships between power data in two bands (i.e. 4-6 and 6-9Hz) of electrical activity in the brain at 14 months, as measured by background electroencephalograms (EEG), with protodeclarative and protoimperative pointing at 18 months, as measured by the Early Social Communication Scales (ESCS), [Mundy et al., ESCS: A(More)
This study used an intact group comparison to examine attention following in 34 children aged 2 years diagnosed with autism spectrum disorder (ASD) matched pairwise for vocabulary comprehension with a group of typically developing toddlers. For both groups of children, the presence of verbal labels during a referential task increased attention to a novel(More)
The forms, functions, and complexity of nonverbal communication used by very young children with autism were investigated. Fourteen children with autism were matched to 14 children with developmental delays and/or language impairments on the basis of CA, MA, and expressive vocabulary. Subjects participated in a structured communication assessment consisting(More)
Thirty-five children who received an autism spectrum diagnosis at the age of 2 years (24 with autism, 11 with PDD-NOS) were re-evaluated 2 years later to examine factors related to the development of spoken language. Child variables (play level, motor imitation ability and joint attention) and environmental variables (socioeconomic status and hours of(More)
PURPOSE The aims of this article are twofold: (a) to offer a set of recommended measures that can be used for evaluating the efficacy of interventions that target spoken language acquisition as part of treatment research studies or for use in applied settings and (b) to propose and define a common terminology for describing levels of spoken language ability(More)
PURPOSE The goal of the current study was to identify a predictive model of vocabulary comprehension and production in a group of young children with autism spectrum disorders. Four prelinguistic behaviors were selected for consideration as predictors based on theoretical and empirical support for the relationship of these behaviors to language development.(More)
