Does cognition in the disconnected right hemisphere require right hemisphere possession of language?

Journal/Book: Brain Lang. 1997; 57: 525 B St, Ste 1900, San Diego, CA 92101-4495. Academic Press Inc Jnl-Comp Subscriptions. 12-21.

Abstract: It has been asserted at times that the human right hemisphere is cognitively inferior to that of a chimpanzee or even a monkey. Related is the even stronger claim that human consciousness, as well as cognition, requires language. These claims are discussed, and counterexamples are presented from both split-brain subjects and patients hemispherectomized in adulthood after customary development as right-handers.
