Psychological stress in Broca's versus Wernicke's aphasia

  • Published 2007


We advance the hypothesis here that the higher-than-average vocal pitch (FO) found for speech of Broca’s.aphasics in experimental settings is due, in part, to increased psychological stress. Two experiments were conducted which manipulated conversational constraints and the sentence forms to be produced by aphasic patients. Our study revealed significant differences between changes in vocal pitch of agrammatic Broca’s aphasics versus those of Wernicke’s aphasics and normal controls. It is suggested that the greater psychological stress experienced by the Broca’s aphasics, but not by the Wernicke’s aphasics, accounts for these observed differences.
