Objective, quantitative measures of caregiver-child interaction during play are needed to complement caregiver or examiner ratings for clinical assessment and tracking intervention responses. In this exploratory study, we examined the feasibility of using automated video tracking, Noldus EthoVision XT, to measure 159 2-to-7-year-old autistic…

Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

The diagnostic criteria for autism spectrum disorder in the DSM-5-TR features the option to designate levels of support for social communication (SC) and restricted, repetitive behaviors (RRB). These levels are conceptual in nature, but research indicates standardized assessment outcomes correspond with clinician-assigned levels of support. The…

This manuscript aimed to advance our understanding of inhibitory control (IC) in autism spectrum disorders (ASD), adopting a meta-analytic multilevel approach. The first meta-analysis, on 164 studies adopting direct measures, indicated a significant small-to-medium (g = 0.484) deficit in the group with ASD (n = 5140) compared with controls (n =…

Previous studies have reported that ASD children with more severe symptoms are diagnosed earlier. However, previous studies in community settings have mostly relied on retrospective parental reports without the use of quantitative standardized test scores. Here, we evaluated the association of language, cognitive, and ASD severity standardized…

Black children with autism are diagnosed at an older age. Whether or not late detection is paralleled by differing clinical presentation is not known. We evaluated symptom profiles of 245 Black and 488 sex- and age-matched White non-Hispanic participants (82.8% male; mean age: 4.2 years) referred for ASD diagnosis. Both groups showed similar…

This study examined differences in generalized and social anxiety symptoms across two age groups of children with autism spectrum disorder (ASD) while accounting for overall anxiety level, gender, and intellectual functioning. Older children (12-18 years) expressed more overall and social anxiety symptoms than younger children (6-11 years), and…

Inconsistent findings regarding sex differences in cognition have been found in people with autism spectrum disorder (ASD). This study evaluated sex differences in cognitive-developmental functioning in a large clinical sample of young children diagnosed with ASD. The sample included children 18-68 months of age who received the Mullen Scales of…

The processing speed index (PSI) of the Wechsler intelligence scale for children (WISC-IV) has been found to predict a child's level of academic functioning. The consistently reported PSI weakness in children with autism spectrum disorder (ASD) therefore warrants special assistance and attempts at compensation for the disadvantages associated with…

Assessment of anxiety in children with autism spectrum disorder (ASD) most commonly includes parent questionnaires. However, due to the nature of the questions and verbal limitations often present in children with ASD, caregivers may have difficulty completing such measures. Caregivers of 144 children with ASD ages 6 to 12 completed the Child and…

Feeding difficulties related to selective intake, or eating a limited variety of foods, are very common in children with autism spectrum disorder (ASD). A systematic search of PubMed, Embase, PsycInfo, and CINAHL identified 29 studies that evaluated eight correlates: age, ASD symptoms and severity, cognitive and adaptive skills, sensory processing…

This study aimed to investigate factors associated with a delayed autism spectrum (ASD) diagnosis when compared to children with either no or early ASD diagnosis. Among 893 children assessed for ASD before age 8, 39% had no ASD at baseline, of which 21% received a later ASD diagnosis. Autism symptoms, diagnostic history of other developmental…

Recent research has documented impaired ability to resist interference from visual distractors in individuals with autism spectrum disorder (ASD) and suggests that this phenomenon may be more pronounced in young versus older children (Christ et al., "Neuropsychology" 25(6):690-701, 2011). The present study extends previous findings by…

Portable touch-screen devices have been the focus of a notable amount of intervention research involving individuals with autism. Additionally, popular media has widely circulated claims that such devices and academic software applications offer tremendous educational benefits. A systematic search identified 19 studies that targeted academic…

Some evidence suggests that bilingualism improves communication and cognitive skills which are often impaired in autism. However, diagnosing autism in bilinguals may suffer a cultural bias, which can affect the investigation of bilingualism and autism. Therefore, the current study investigates relations between autistic-like traits (ALTs) and…
