Numerous studies have investigated the predictors of language in pre-verbal toddlers and verbally fluent children with autism spectrum disorder (ASD). The present study investigated the concurrent relations among expressive language and a set of empirically-selected social communication variables--joint attention, imitation, and play--in a unique…

Comprehensive interventions for children with autism spectrum disorder (ASD) often incorporate augmentative and alternative communication (AAC); however, variability in outcomes exists even among children who access similar intervention. This study investigated predictors of expressive language change for 48 children with ASD aged 31 to 67 months…

Few interventions exist for school-aged minimally verbal children with autism spectrum disorder (ASD). Even though play skills are associated with children's production of language, few studies have focused on play for minimally verbal children. Fifty-eight minimally verbal children with ASD received a naturalistic developmental behavioral…

Young children with autism spectrum disorder (ASD) often demonstrate delays in expressive communication, impacting their ability to independently function in typical environments. Individuals with ASD who develop expressive language during early childhood experience better outcomes later in life; therefore, examination of naturalistic language…

We investigated which item subsets of the Vineland-II can discriminate low-functioning preschoolers with ASD from matched peers with other neurodevelopmental disorders, using a regression analysis derived from a normative sample to account for cognitive and linguistic competencies. At variance with the typical profile, a pattern with Communication…

This study examined associations between three parent-child engagement states and social communication, expressive language, and receptive language at 8 month follow-up, in 63 preschool-age children with autism spectrum disorder. We extend the literature on supported joint engagement by dividing this state into higher order (HSJE) and lower order…

Longitudinal research has demonstrated that responsive parental behaviors reliably predict subsequent language gains in children with autism spectrum disorder. To investigate the underlying causal mechanisms, we conducted a randomized clinical trial of an experimental intervention (Focused Playtime Intervention, FPI) that aims to enhance…

Developmental regression is a complex phenomenon which occurs in 20-49% of the autistic population. Aim of the study was to assess possible differences in the development of regressed and non-regressed autistic preschoolers. We longitudinally studied 40 autistic children (18 regressed, 22 non-regressed) aged 2-6 years. The following developmental…

The relationship between symbolic play and other domains, such as degree of autistic symptomatology, nonverbal cognitive ability, receptive language, expressive language, and social development, was investigated. The assessment files of 101 children with Autism Spectrum Disorder were studied. Nonverbal cognitive ability and expressive language…

Studies are needed to better understand the broad autism phenotype in young siblings of children with autism. Cognitive, adaptive, social, imitation, play, and language abilities were examined in 42 non-autistic siblings and 20 toddlers with no family history of autism, ages 18-27 months. Siblings, as a group, were below average in expressive…

The study investigated the effects of two levels of teacher intrusion upon the behavior of eight elementary level autistic children and their nonhandicapped peers during dyadic play interactions. Few differences in subject behavior were observed, though the low-intrusion condition was associated with higher levels of toy contact and fewer…

Two mentally retarded boys with autism and one girl with Down syndrome were successfully taught to initiate and play a ball game with an adult. The program targeted both nonverbal responses (such as ball contact and cooperative play) and verbal responses for play initiation and compliment delivery. (Author/JDD)
