Perceptual development, layout perception in infants, the treatment of prosopagnosia (face blindness) and ASD in children. 

Yonas Research Lab

Yonas, his students, and collaborators are creating methods for treating children suffering from Autism Spectrum Disorders and Developmental Prosopagnosia, “face blindness,” by using computer games.

Yonas is also working with Pawan Sinha at MIT to study the development of visual perception in children who are born blind (due to dark cataracts) but not been able to receive any treatment to cure their condition. This is very different from what happens to similar American infants, who have surgery within their first months of life. The Indian children are from very poor rural villages. Professor Sinha’s project makes it possible for them to travel with their parents to a modern hospital in a large city to have cataract surgery.  Over his career, Yonas' research has explored the development of 3-D perception by isolating different cues for spatial layout to discover when infants begin to use such to reach for the closer of two objects.  With the older Indian children, we will be able to ask them to tell us what they see, which clearly provides much more useful data than simple reaches. 

Furthermore, in a new study Yonas and his students will test the notion that as young infants come to see 3-D shapes (bulges) from shading, they lose the ability to detect small differences in the images.
