Children with autism may learn from 'virtual peers'

EVANSTON, Ill. --- Using “virtual peers” -- animated life-sized children that simulate the behaviors and conversation of typically developing children -- Northwestern University researchers are developing interventions designed to prepare children with autism for interactions with real-life children.

Justine Cassell, professor of communication studies and electrical engineering and computer science, recently presented a preliminary study on the work at a meeting of the American Association for the Advancement of Science.

“Children with high-functioning autism may be able to give you a lecture on a topic of great interest to them but they can’t carry on a ‘contingent’ -- or two-way -- conversation,” said Cassell, director of Northwestern’s Center for Technology and Social Behavior.

Cassell and researcher Andrea Tartaro collected data from six children with high-functioning autism aged 7 to 11 as they engaged in play during an hour-long session with a real-life child, and with a virtual peer named Sam.

In an analysis of those interactions, they found that children with autism produced more and more “contingent” sentences when they spoke with the virtual peer, while their sentences did not become increasingly contingent when they were paired with the real-life children.
