Using eye-tracking technology, researchers at Washington University School of Medicine in St. Louis and Emory University School of Medicine in Atlanta have found compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people’s eyes and faces or at objects. The discovery adds new detail to understanding the causes of autism spectrum disorder. Studying twins, the researchers found that where babies focus their eyes is under stringent genetic control.
