Abstract: 

The researchers tracked eye movements and blinks in 41 2-year-olds with autism and 52 healthy controls while the children watched a short movie of two toddlers on a playground. Both groups on average blinked about five times per minute. But they differed significantly in how their blinking lined up with the content of the movie.

Healthy toddlers refrained from blinking as they watched scenes with high emotional content, such as when the toddler-actors fought about a toy. Toddlers with autism, in contrast, were just as likely to blink during emotional scenes as during dull ones.
