title: Verbal expression of right cerebrovascular accident patients: convergent and divergent language.
abstract: This investigation examined the role of the right hemisphere in language expression. Three groups of 12 subjects each--right CVAs, left CVAs, and controls--performed convergent and divergent language tasks of naming, function, and connected speech. For all convergent tasks and for number of words, number of message units, and fluency in divergent connected speech, controls surpassed both brain-damaged groups, who performed similarly. For the other divergent tasks, controls were superior to the brain-damaged groups, but the right CVAs outperformed the left CVAs. In general, verbal expression problems of right-hemisphere-damaged patients were almost as severe as those of left-hemisphere-damaged patients.
