We examined differences between children with autism spectrum disorder and typically developing children over an 8-month period in: (a) longitudinal associations between expressive and receptive vocabulary and (b) the extent to which caregiver utterances provided within an "optimal" engagement state mediated the pathway from early…

Background: There is a growing body of literature investigating the efficacy of music interventions for children with autism spectrum disorder (ASD); however, little empirical research has been conducted into the use of musical elements to facilitate language learning. Methods: This crossover-design study compared the responses of 22 children with…

Naturalistic interventions show promise for improving language in children with autism. Specific interventions differ in direct elicitation of child language and indirect language stimulation, and thus may produce different language outcomes. This study compared the effects of responsive interaction, milieu teaching, and a combined intervention on…

Characterizing early communicative development in children with Autism Spectrum Disorders (ASD) is valuable for understanding profiles of ability in this population. The current investigation was modeled on Charman, Drew, Baird & Baird (2003b). Analyses explored parent report of early vocabulary, non-verbal communication, functional object use and…

Review of literature on indicators of the effectiveness of language intervention programs for autistic children showed that mitigation in echolalia was a critical characteristic, as it implied that the prerequisites for language were accessible through speech. Children whose speech ranged from mutism to unmitigated echolalia had a more negative…

This study of 80 autistic (ages 6-18), mentally handicapped, and normal children found that more autistic subjects used neologisms and idiosyncratic language than age- and language-skill-matched control groups. More autistic children used words inappropriately that were neither phonologically nor conceptually related to intended English words than…
