Toddlers with autism may closely monitor co-occurring sights and sounds, resulting in a neglect of social signals
When 2-year-olds with autism look at someone’s face, they may crave synchronized detection rather than social connection. Toddlers with this developmental condition track sounds and sights that occur together, such as a mother’s lips moving in time with sounds coming out of her mouth, rather than social cues, such as the gleam in that same mother’s eyes, a new study suggests.

“Our findings lead us to the rather sad hypothesis that a toddler with autism might watch a face but not necessarily experience a person, since so much of that experience involves mutual eye gaze,” Klin says.
The new study, published online March 29 in Nature, indicates that by age 2, kids with auti
