Corina, David P.; McBurney, Susan L. – Journal of Communication Disorders, 2001
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…

Rondal, J. A.; Elbouz, M.; Ylieff, M.; Docquier, L. – Down Syndrome Research and Practice, 2003
This paper reports on a 15-year follow-up of the linguistic and cognitive profile of a woman with standard trisomy 21 (Down syndrome). The follow-up found recent rapid deterioration in receptive and productive language skills. However, basic phonological and morphosyntactic skills are preserved. Her changing profile mirrors that found in aging…

Ertmer, David J.; Mellon, Jennifer A. – Journal of Speech, Language, and Hearing Research, 2001
Early vocal development, consonant production, and spoken vocabulary were examined in a deaf toddler whose multichannel cochlear implant was activated at 20 months. The child understood almost 240 words and spoke approximately 90 words after one year of implant experience. The combination of early cochlear implantation, family support, and regular…
