Researchers have focused on how deaf signing children acquire and use American Sign Language (ASL). One sub-skill of ASL proficiency is ASL phonology. This includes the ability to isolate and manipulate parameters within signs (i.e., handshape, location, and movement). Expressively, signed language phonological fluency tasks have investigated…

Studies of American Sign language including functional magnetic resonance imaging of deaf signers confirms the importance of left hemisphere structures in signed language, but also the contributions of right hemisphere regions to sign language processing. A case study involving cortical stimulation mapping in a deaf signer provides evidence for…
