  • Title: "Prepairs" and repairs: different monitoring functions in aphasic language production.
    Author: Schlenck KJ, Huber W, Willmes K.
    Journal: Brain Lang; 1987 Mar; 30(2):226-44. PubMed ID: 2436704.
    Abstract:
    Picture descriptions of aphasic patients and nonaphasic controls were analyzed with respect to type and amount of linguistic repairs and searching phenomena ("prepairs"). Repairs occurred far less frequently than prepairs, which indicates impaired postarticulatory as opposed to intact prearticulatory monitoring. Prepairs were found to be most frequent in patients with relatively good comprehension, in patients with poor production, and in those who had both good comprehension and poor production. Contrary to expectation, there was no reliable difference in the distribution of prepairs and repairs between patients with Wernicke's and Broca's aphasia, although these two groups differed in performance. Possible mechanisms of linguistic monitoring are discussed.
