The gaze of children as young as 16 months old may help predict whether they have autism and reveal finer-grained details, such as their verbal and social abilities.

Genetics may govern a person’s ability to pay attention to social cues.

Eye tracking shows that mavoglurant, a once-abandoned experimental drug for fragile X syndrome, enters the brain and boosts social interest, says Elizabeth Berry-Kravis.

Scientists are finding new ways to test cognition in autistic individuals who speak little or not at all.

Autistic people who have trouble speaking or moving often do poorly on standard tests of intelligence. Newer methods promise to uncover their abilities — and improve our understanding of autism itself.

After the presentation of more than 14,000 abstracts over five days, the Society for Neuroscience annual meeting in San Diego ended last week.

Rhesus macaques that are drawn to other monkeys’ faces in videos also tend to be highly social with their peers.

Two novel algorithms that analyze where a child looks as she views a video could help clinicians spot autism.

A new assemblage of tools precisely gauges a baby’s biological response to sights, sounds and tactile stimuli all at once.

The pupils of babies later diagnosed with autism shrink more in response to light than those of their typical peers.
