Deaf Vision

Have you ever wondered whether deaf people see the world differently than hearing people do?

Or whether deaf people have enhanced vision because they use a visual language every day? We have recently been funded by the National Science Foundation and National Eye Institute to study whether deafness and sign language experience change visual perception over the course of the lifespan from infancy to adulthood. Our goal is to measure different visual abilities (including motion, face and shape perception) in deaf and hearing infants, children, and adults. We are also interested in studying children who have or will receive cochlear implants who might also have altered visual abilities. By understanding the developmental trajectory of altered vision due to deafness and/or sign language, we hope to elucidate mechanisms of developmental plasticity. We also hope to further develop tools for language and cognitive assessments used for Deaf children.

If you are in one of the following groups of people, we would love to have you in our lab. Our studies involve interviews, short questionnaires and computerized game-like tests of visual perception and visual reasoning skills. We provide monetary compensation, small prizes for children, and free parking.

We are currently recruiting:

-Deaf or Hard of Hearing infants and children
-Infants and children with Cochlear Implants
-Deaf Adults who use Sign Language
-“CODA” Infants and children – hearing or deaf children who have deaf parents who use sign language
