Best practice for the assessment of autism spectrum disorder (ASD) symptom severity relies on clinician ratings of the Autism Diagnostic Observation Schedule, 2nd Edition (ADOS-2), but the association of these ratings with objective measures of children's social gaze and smiling is unknown. Sixty-six preschool-age children (49 boys, M =…

Background: In typically developing (TD) children, gesture emerges around 9 months of age, allowing children to communicate prior to speech. Due to the important role gesture plays in the early communication of autistic and TD children, various tasks have been used to assess gesture ability. However, few data exist on whether and how tasks…

This study examined the effects of an intervention package using high-tech augmentative and alternative communication (AAC) with Naturalistic Instruction (NI), time delay, and prompting during social routines for preschoolers on the autism spectrum. The AAC was a communication application on a tablet programmed with color photo representations of…

Background: Within cohorts of children with autism spectrum disorder (ASD) there is considerable variation in terms of language ability. In the past, it was believed that children with ASD either had delayed articulation and phonology skills or excelled in those areas compared to other language domains. Very little is known about speech sound…

The purpose of the present study was to investigate the direct and indirect relationships between autism traits and listening comprehension among Chinese preschool children with autism, of varying verbal and non-verbal IQ. Ninety-eight (N = 98) children aged from 35 to 86 months participated in the study. Autism traits were measured with the…

Starting early in life, autistics are characterized as having atypical facial expressions, as well as decreased positive and increased negative affect. The literature on autistic facial expressions remains small, however, with disparate methods and results suggesting limited understanding of common autistic emotions. Furthermore, unlike…

The purpose of this study was to determine the effectiveness of a peer mediated intervention to increase social communication acts of preschool children with autism spectrum disorder (ASD). Utilizing a single-subject A-B design across four peer dyads, I examined the overall effectiveness of the intervention in relation to specific nonverbal,…

Early gesture plays an important role in prelinguistic/emerging linguistic communication and may provide insight into a child's social communication skills before the emergence of spoken language. Social interactionist theories suggest children learn to gesture through daily interactions with their social environment (e.g., their parents). As…

Introduction: Autism Spectrum Disorders (ASD) are a continuum of traits that may negatively affect social and emotional competencies of individuals, including challenges in their engagement abilities, possible limitations in reciprocal interactions, and inflexibility in initiating and sustaining communication. Such challenges may affect language…

Purpose: Children with autism are found to have delayed and heterogeneous gesture abilities. It is important to understand the growth of gesture abilities and the underlying factors affecting its growth. Addressing these issues can help to design effective intervention programs. Method: Thirty-five Chinese-speaking preschoolers with autism…

Background and Aims: Children with autism spectrum disorder (ASD) present with impairments in social interaction and stereotypic behaviors. About a third may exhibit delays in verbal expression beyond preschool age, potentially categorizing them as nonverbal/minimally verbal (NV/MV), a condition that can persist into adulthood and affect their…

The purpose of this study was to evaluate the use of an interrupted chain procedure and a time delay with full physical prompts, in the establishment of peer manding, within a naturally occurring classroom routine. The participants included three preschool aged children with autism spectrum disorder (ASD), who used a tablet-based speech-generating…

This pilot placebo-controlled trial (NCT00965068, 07/28/2009) explored effects of cholesterol supplementation on autism spectrum disorder (ASD) symptoms in children with abnormally low cholesterol. Fifteen children age 4-12 with ASD and cholesterol <5th percentile for age/sex were randomized to 225 mg cholesterol vs. matched placebo twice daily…
