To demonstrate the capability of computer vision analysis to detect atypical orienting and attention behaviors in toddlers with autism spectrum disorder. One hundered four 16-31 months old (mean = 22) participated this study. Twenty-two had disorder 82 typical development or developmental delay. Toddlers watched video stimuli on a tablet while built-in camera recorded their head movement. Computer measured participants' response name calls. Reliability algorithm was tested against human...
Evidence suggests that differences in motor function are an early feature of autism spectrum disorder (ASD). One aspect ability develops during childhood is postural control, reflected the to maintain a steady head and body position without excessive sway. Observational studies have documented control older children with ASD. The present study used computer vision analysis assess midline as rate spontaneous movements states active attention, 104 toddlers between 16-31 months age (Mean = 22...
Commonly used screening tools for autism spectrum disorder (ASD) generally rely on subjective caregiver questionnaires. While behavioral observation is more objective, it also expensive, time‐consuming, and requires significant expertise to perform. As such, there remains a critical need develop feasible, scalable, reliable that can characterize ASD risk behaviors. This study assessed the utility of tablet‐based assessment eliciting detecting one type behavior, namely, patterns facial...
Individuals with autism spectrum disorder are more likely than typically developing individuals to experience a range of gastrointestinal abnormalities, including chronic diarrhea, constipation, food sensitivities, and abdominal pain. These symptoms have been associated higher levels irritability aggressive behavior, but less is known about their relationship core symptoms. We investigated the between symptom severity while accounting for three behavioral domains (Irritability,...
Abstract To improve early identification of autism spectrum disorder (ASD), we need objective, reliable, and accessible measures. that end, a previous study demonstrated tablet‐based application (app) assessed several risk behaviors distinguished between toddlers with ASD non‐ASD toddlers. Using vocal data collected during this study, investigated whether vocalizations uttered administration app can distinguish among aged 16–31 months typical development (TD), language or developmental delay...
Executive functioning describes a set of cognitive processes that affect thinking and behavior. Past research has shown autistic individuals often have delays in the acquisition executive function abilities. Our study explored how differences attention abilities relate to social communication/language 180 young children. Data were gathered via caregiver report (questionnaires/interviews) an assessment vocabulary skills. The ability sustain dynamic video was measured eye tracking. We found...
Play-based observations allow researchers to observe autistic children across a wide range of ages and skills. We recorded playing with toys in the center room at corner table while caregiver remained seated off side used video tracking technology track children's movement location. examined how time spent regions whether or not they approached each region during play related their cognitive, social, communication, adaptive skills determine if child location can meaningfully demonstrate...
The present study is a single-site quality improvement project within pediatric primary care involving the implementation of digital version Modified Checklist for Autism in Toddlers–Revised. We evaluated impact screener on likelihood physician referral developmental evaluation or autism diagnosis, and age patients at time event. Patients were children 16–30 months old seen 18 24 months’ well-child visits (1279 encounters), who screened positive risk spectrum disorder Toddlers–Revised...
Prior eye-tracking studies involving autistic individuals have focused on total looking time or proportion of to key regions interest. These not examined another important feature, the ability sustain attention stimuli. In particular, a dynamic social stimulus might reflect more advanced self-regulatory skills that may enhance engagement with and comprehension information. sample 155 children (2–8 years age), we children’s average look duration while they viewed complex, containing both...
