Most parents will attest that infants convey their needs and interests in a variety of ways, many times without ever making a sound. For researchers in the School of Behavioral and Brain Sciences, it is what babies communicate with their eyes that could be key to understanding the development of certain disabilities, including autism.
Dr. Noah Sasson, an assistant professor in the school, and his colleagues at the UT Dallas Center for Children and Families, are currently tracking and measuring the eye movements of infants. Eye tracking technology is nothing new to Sasson — he has used it in previous research to investigate how children and adults perceive social and non-social information.
“By tracking eye movements, we can infer information about an infant based on what he or she views and for how long,” said Sasson. “Although this information alone is not diagnostic, certain patterns of eye movements may signify an abnormality that could reflect potential developmental difficulties.”[FULL]
