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…

The objective of this study was to teach manual signs through an automated matching-to-sample procedure and to test for the emergence of new conditional relations and imitative behaviors. Seven adults with mild to severe mental retardation participated. Four were also hearing impaired. Relations between manual signs (set A) and pictures (set B)…

Five profoundly deaf adults were recorded reading lists of individual words under three expressive modes (speech alone, speech and signs, and speech with cues). Results indicated that speech with cues produced the highest level of intelligibility, speech and signs the lowest. (Author/CL)

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…

Forty hearing-impaired adults read and retold short stories, in either English or American Sign Language (ASL). Analysis indicated that there was more explicitness in ASL, with more importance placed on specification of instruments involved in an action. No significant story differences were found between subjects' stories and stories of…
