Purpose: Gesture delay in autistic infants and toddlers has been widely reported. The developmental trajectory of gesture production during early childhood is understudied. Thus, little is known about the possible changes of gesture production over time. The present study aimed to document the development of gesture production in autistic children…

Purpose: Toddlers with Down syndrome (DS) showcase comparable or higher rates of gestures than chronological age-- and language-matched toddlers without DS. Little is known about how gesture use in toddlers with DS relates to multiple domains of development, including motor, pragmatics, language, and visual reception (VR) skills. Unexplored is…

In children with autism spectrum disorder, atypical gesture use is a core deficit with consequences for social learning, social interaction, and language development. Little is known about the relevance of early gesture use in predicting developmental outcomes of children receiving early interventions targeting social-communicative behaviors such…

Autism Spectrum Disorder (ASD) diagnostic tools are not designed for mental ages (MA) below 12 months. Autism Diagnostic Observation Schedule (ADOS) and Childhood Autism Rating Scale (CARS) were examined in 2-year-olds with ASD-low MA (n = 53), Global Developmental Delay (GDD; n = 175), and ASD-higher MA (n = 425). ADOS and CARS demonstrated…

Children with autism have atypical gaze behavior but it is unknown whether gaze differs during distinct types of reciprocal interactions. Typically developing children (N = 20) and children with autism (N = 20) (4-13 years) made similar amounts of eye contact with an examiner during a conversation. Surprisingly, there was minimal eye contact…

Children with autism spectrum disorder (ASD) are often delayed in acquiring social initiation skills utilized during common early childhood activities. A multiple probe design was utilized to assess the efficacy of a shared book reading intervention to increase the independent commenting of three young children with ASD. The intervention resulted…

Positive emotional engagement develops in the context of face-to-face interactions during the first 6 months of life. Deficits in emotional engagement are characteristic of autism spectrum disorder (ASD) and may characterize the younger siblings of children with ASD (high-risk siblings). High-risk siblings are likely to exhibit a broad range of…

This study examined Pathways Early Autism Intervention, a community-based, parent-mediated, intensive behavioral and developmental intervention program for children with autism spectrum disorders that could be used as a model for state-funded early intervention programs. A single-subject, multiple-baseline, across-participants design was used.…

Communication spontaneously initiated by infants at heightened risk (HR; n = 15) for autism spectrum disorders (ASD) is compared with that in low-risk (LR; n = 15) infants at 13 and 18 months of age. Infants were observed longitudinally during naturalistic in-home interaction and semistructured play with caregivers. At both ages, HR infants…

Daily living skills (DLS), such as personal hygiene, meal preparation, and money management, are important to independent living. Research suggests that many individuals with autism spectrum disorder exhibit impairments in daily living skills relative to their cognitive skills. This study examined predictors of daily living skills attainment and…
