Unlike typical toddlers, those with autism tend not to share experiences involving sound — dancing to music with their parents, for example, or calling attention to the source of a sound.

A pair of tools that gauge social abilities in rhesus macaques may help researchers study autism-like behaviors in monkeys.

Autistic infants as young as 6 months display subtle signs of the condition, according to a study of visual attention.

Understanding how gaze differs in autistic people may help improve their lives.

The social brain has a sweet spot that activates when people look each other in the eyes but not when they look at eyes in a video.

The relatives of autistic people often have mild traits of the condition. Studying these family members could broaden our understanding of autism.
