As early identification of autism improves, there is a critical need for interventions to support the development of social communication skills in toddlers. Caregiver coaching and parental involvement is crucial for improving outcomes and providing children with adequate hours of planned active engagement. This pilot study assessed a 4-week…

Infants show shifting patterns of visual engagement to faces over the first years of life. To explore the adaptive implications of this engagement, we collected eye-tracking measures on cross-sectional samples of 10-25-month-old typically developing toddlers (TD;N = 28) and those with autism spectrum disorder (ASD;N = 54). Concurrent language…

We investigated gesture production in infants at high and low risk for autism spectrum disorder (ASD) and caregiver responsiveness between 12 and 24 months of age and assessed the extent to which early gesture predicts later language and ASD outcomes. Participants included 55 high-risk infants, 21 of whom later met criteria for ASD, 34 low-risk…

We examined language profiles of 2571 children, 30-68 months old, with autism spectrum disorder (ASD), other developmental disabilities (DD), and typical development from the general population (POP). Children were categorized as expressive dominant (ED), receptive dominant (RD), or nondominant (ND). Within each group, the ED profile was the least…

The current study compared adaptive and cognitive skills, and autism severity of toddlers with an autism spectrum disorder (ASD) diagnosis under DSM-IV but not DSM-5 criteria (DSM-IV only group) to those who met autism criteria under both diagnostic systems (DSM-5 group) and to those without ASD (non-ASD group). The toddlers in the DSM-IV only…

To explore how being at high risk for autism spectrum disorder (ASD), based on having an older sibling diagnosed with ASD, affects word comprehension and language processing speed, 18-, 24- and 36-month-old children, at high and low risk for ASD were tested in a cross-sectional study, on an eye gaze measure of receptive language that measured how…

This study examined the longitudinal associations between parent verbal responsiveness and language 3 years later in 34 toddlers with a diagnosis of an autism spectrum disorder. Parent-child play samples were coded for child engagement and communication acts and for parent verbal responsiveness. Measures of responsive verbal behaviors were used to…

This prospective, longitudinal, study charted the developmental profiles of young children with Autism Spectrum Disorders (ASD) identified through routine developmental surveillance. 109 children with Autistic Disorder (AD), "broader" ASD, and developmental and/or language delays (DD/LD) were assessed using the Mullen Scales of Early Learning…

This study characterized early language abilities in toddlers with autism spectrum disorders (n = 257) using multiple measures of language development, compared to toddlers with non-spectrum developmental delay (DD, n = 69). Findings indicated moderate to high degrees of agreement among three assessment measures (one parent report and two direct…

Systematic longitudinal observations were made as typically developing toddlers and young children with autism and with Down syndrome interacted with their caregivers in order to document how joint engagement developed over a year-long period and how variations in joint engagement experiences predicted language outcome. Children with autism…

One of the primary diagnostic criteria for the diagnosis of autism spectrum disorders (ASD) is the presence of a language delay or impairment. Children with ASD are now being identified at significantly younger ages, and prior research has consistently found that early language skills in this population are heterogeneous and an important predictor…
