The distinct biological basis of sign language results in a unique interaction between vision and language and between action systems and language production. This project investigates the possible effects of experience with a visual-spatial language and the effects of auditory deprivation from birth on non-language visual perception and on spatial cognition. Specifically, we are addressing the following questions using behavioral methods and neuroimaging:
- How does knowing a visual-spatial language affect visual-spatial cognition?
- Do visual perspective taking abilities differ between deaf signers and hearing speakers?
- Why does short term memory span differ between speech and sign?
- Are theories of action perception and production relevant to sign language?
