Exam 16: Lateralization, Language, and the Split Brain

Bob is dyslexic. Most of his errors occur because he has difficulty applying the rules of English pronunciation. He might say "hen" for "chicken" or "wise" for "wisdom." Bob has __________ dyslexia.

Of the 214 aphasic patients in the classic Hecaen and Angelergues's study, how many displayed disorders of language that were purely expressive (i.e., Broca's aphasia) or purely expressive (i.e., Wernicke's aphasia)?

The findings of the brain stimulation studies of Ojemann and colleagues suggest that language abilities might be organized in the cortex like a
