Watch the complete replay of Evelina Fedorenko discussing language processing and development in autism.

New artificial-intelligence software detects and analyzes the ultrasonic squeaks and cries that constitute inaudible rodent language.

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.

A monkey-sized jacket embedded with motion sensors — similar to technology used to animate creatures in movies — is helping researchers develop the common marmoset as a model for studying human social behavior.

Inhibiting the social hormone oxytocin alters the songs male zebra finches sing to attract females.

The pattern of high-pitched calls a mouse makes may reflect how, and how much, it is interacting with other mice. The pattern holds for typical mice as well as for two mouse models of autism.

Mice lacking one copy of a gene linked to autism are small and show striking changes in the number and quality of their cries.

Fever in pregnant rats around the time of delivery disrupts their pups’ communication and social behavior.

Rats with a mutation in CACNA1C, a gene linked to autism, make fewer happy squeaks while playing than controls do, and ignore other rats’ requests to play.
