Purpose: This exploratory study examined predictive relationships between 5 types of behaviors and the trajectories of vocabulary and language development in young children with autism over 2 years. Method: Participants were 69 children with autism assessed using standardized measures prior to the initiation of early intervention (T1) and 6 months (T2), 12 months (T3), and 24 months (T4) later. Growth curve modeling examined the extent to which behaviors at T1 and changes in behaviors between

Method: Communicative acts were examined in 125 children 18 to 24 months of age: 50 later diagnosed with ASD; 25 with developmental delays (DD); and 50 with typical development (TD). Precise measures of rate, functions, and means of communication were obtained through systematic observation of videotaped behavior samples from the Communication and Symbolic Behavior Scales Developmental Profile (A. Wetherby B. Prizant, 2002). Results: Children with ASD communicated at a significantly low

Conclusions: By 18 to 24 months of age, children later diagnosed with ASD showed a unique profile of communication, with core deficits in communication rate, joint attention, and communicative gestures. from the Journal of Speech, Language, and Hearing Research

Abstract We investigated correlates of language regression for children diagnosed with autism spectrum disorders (ASD). Using archival data, children diagnosed with ASD (N = 114, M age = 41.4 months) were divided into four groups based on language development (i.e., regression, plateau, general delay, no delay) and compared on developmental, adaptive behavior, symptom severity, and behavioral adjustment variables. Few overall differences emerged between groups, including similar non-language de

More pieces in the complex autism inheritance puzzle are emerging in the latest study from a research team including geneticists from The Children's Hospital of Philadelphia, the University of Pennsylvania School of Medicine and several collaborating institutions. This study identified 27 different genetic regions where rare copy number variations - missing or extra copies of DNA segments - were found in the genes of children with autism spectrum disorders (ASDs), but not in the healthy controls
