Autism is difficult to detect in infants and toddlers, but treating it at an early age can improve a child's language and IQ scores.

Researchers from Yale and Canada's McMaster University are studying eye movement in young children with the hope of learning more about diagnosing the disease, according to the Wall Street Journal. They want to figure out how to diagnose and treat autism earlier and believe learning more about what interests and motivates the autistic mind will help them do so.

This amazing video shows how the researchers go about tracking how a baby looks at a human face. Researchers suspect autistic infants and toddlers may have different scanning patterns than those without it.
