Where an infant fixes their gaze 'could be an early indicator of autism' - Daily Mail Researchers at the Kennedy Krieger institute and University of Delaware studied 25 six-month-old infants in this 'high-risk' group along with 25 of their peers. The youngsters were placed in a chair with a simple joystick. When they moved it the musical toy was activated and they were given more attention by their caregiver. When actively engaged the children in both groups spent a similar amount of time looking at the person as they did at the toy. However, the team found that when the babies were not being engaged, those in the high risk group spent far more time gazing at the toy than the caregiver.
