All of the children had been flagged as being at risk for autism and referred to a clinic for standard diagnostic testing 91 of them received an autism diagnosis based on standard clinical tests. The researchers used eye-tracking data from 201 children aged 1 to 17 years to create algorithms that predict autism risk and severity. In the new study, researchers parlay this disparity in gaze into a diagnostic tool. People on the spectrum tend to focus on different parts of an object or scene than their typical peers do 2. Some scientists have suggested that eye tracking could speed autism diagnosis and make it more objective. These assessments can take up to three hours to administer. They might also provide clues to the severity of the child’s autism features, according to a new study 1.Ĭlinicians typically diagnose autism using both a caregiver questionnaire (the Autism Diagnostic Interview-Revised) and a rigorous clinical evaluation called the Autism Diagnostic Observation Schedule (ADOS). Two novel algorithms that analyze where a child looks as she views a video could help clinicians spot autism. Watchful gaze: Researchers track a person’s eyes as they land on ‘regions of interest,’ such as a face or objects in the environment.Ĭourtesy of Thomas Frazier and Eric Klingemier / Cleveland Clinic Children’s Center for Autism
