Abstract:
Many theories for explaining speech production problems in apraxia of speech (AOS) have been advanced. Schmidt's schema theory of motor control has been widely used to explain motor learning in normal subjects as well as in individuals with motor speech disorders especially, AOS. Several studies have provided the data on motor learning in limb system from the perspective of schema theory of motor control and learning. Those studies investigated important variables of motor learning such as practice (random and blocked), feedback (100% feedback, reduced feedback), and their influence on acquisition and retention. However, few studies have investigated motor speech production for AOS. Furthermore, many of the variables directly related to relearning or learning outcomes of complex motoric speech behavior have gone uninvestigated. The purpose of this study was to determine the effect of the manipulation of several parameters (the schedules of practice trials, the schedules of feedback, and retention) of motor learning theory on the verbal acquisition and retention of words in a foreign language (Korean). Thirty two normal English speaking subjects participated in this study. Ten Korean sentences were presented for each participant to practice. The subjects were directed to practice by listening to the sentences that the experimenter orally modeled for them. The speech samples were produced with one day of retention and one week of retention following training. The results showed that the combination of 100 practice trials and 20% feedback was more effective than the other combinations on the retention of novel verbal productions of Korean phrases one day after training. Also, the effects of the combination of 100 practice trials and 20% reduced feedback were retained one week after acquisition. ; A Dissertation submitted to the Department of Communication Disorders in partial fulfillment of the requirements for the degree of Doctor of Philosophy. ; Summer Semester, 2007. ; January 25, 2007. ; Practice Trials On Motor Speech Retention, Apraxia Of Speech, Treatment Of Apraxia Of Speech, Retention, Motor Learning Theory, Effect Of Feedback Schedules ; Includes bibliographical references. ; Leonard L.
