The current study investigated the impact of birth order on vocabulary and social language development in 1338 first-born and 1049 s-born autistic youth (M age = 9.03 years, SD = 3.57; 86.4% male) from the Simons Simplex Collection. Frequentist and Bayesian analyses revealed mixed findings in language development. There were no differences in…

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…

This study tested the hypothesis that pragmatic (i.e., social) language impairment is linked to arousal dysregulation in autism spectrum disorder (ASD) and fragile X syndrome (FXS). Forty boys with ASD, 39 with FXS, and 27 with typical development (TD), aged 4-15 years, participated. Boys with FXS were hyperaroused compared to boys with TD but did…

This community effectiveness trial examined the feasibility and efficacy of a comprehensive psychosocial treatment for 28 children, aged 7 to 10 years with high-functioning autism spectrum disorders (HFASDs). Treatment included instruction and therapeutic activities targeting social skills, face-emotion recognition skills, interest expansion, and…

The purpose of this study was to investigate the effects of peer intervention on the social interactions of children with autism spectrum disorder (ASD). In this model, a speech-language pathologist and three early childhood educators trained typically developing peers to engage children with ASD in play. Three preschool children with ASD and six…

Qigong massage is an eastern form of massage that can be delivered by western parents to their children with appropriate training and support. It has been shown to improve developmental measures in young children with autism when given daily for five months. A recent trial evaluating its effect on motor development in young children with Down…

Prospective questionnaire data from a longitudinal population sample on children with autism spectrum disorders (ASD), developmental delay, specific language impairment, or typical development (TD), were collected at ages eight, 12 and 24 months, via the Communication and Symbolic Behavior Scale Developmental Profile (CSBS)--Infant Toddler…

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…

This study aimed to investigate the relationships between abilities to initiate and respond to joint attention and symptoms of autism that have, and have not, been theoretically linked to joint attention. Participants were 51 boys and five girls with autistic disorder, aged between 2 years and 6 years 5 months. Measures of joint attention…

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 monograph describes a systematic attempt to develop language behavior in a nonverbal autistic 4.5-year-old boy who was essentially unresponsive to environmental stimuli of any kind. The 45-session intervention focused on teaching him to attend, increasing his responsiveness to people, effecting discriminative responses to a variety of…

The present study examined the social significance of changes resulting from teaching symbolic play skills to children with autism using Pivotal Response Training (PRT). Qualitatively obtained results from a previous study indicated that, following symbolic play training, children with autism increased their symbolic play behaviors and play…

The article describes language development techniques used with a 5-year-old autistic boy to increase his verbal behavior. Intervention consisted of 1.5 hour sessions four times a week over an 8-month period. The intervention focused on increasing nonvocal imitation, vocal imitation, verbal labeling, and verbal discrimination. Development of…

Background: Psychosocial treatments are the mainstay of management of autism in the UK but there is a notable lack of a systematic evidence base for their effectiveness. Randomised controlled trial (RCT) studies in this area have been rare but are essential because of the developmental heterogeneity of the disorder. We aimed to test a new…

Joint attention refers to an early developing set of behaviors that plays a critical role in both social and language development and is specifically impaired in children with autism. In a series of three studies, preschool teachers demonstrated the effectiveness of discrete trial instruction and pivotal response training strategies to teach joint…
