Abstract

The purpose of this study was to examine the effects of speaking rate on the ratio of phonological sequencing errors (anticipation/exchange, anticipation/perseveration) and other error (distortion) types in non-brain-damaged individuals and in persons with aphasia who were without concomitant motor speech disorders. The participants self-manipulated their speaking rate while performing a phonologically challenging (tongue twister) speech production task. While null results were obtained for most comparisons, a significant effect of rate was obtained for the anticipation/perseveration ratio. Results are discussed relative to the Dell (1986) speech production model from which the predictions were derived.
