Abstract
Stuttering is manifested as a disruption in speech timing, but it may stem from a more basic temporal disorder (R. D. Kent, 1984). We compared the ability of stuttering and nonstuttering adults to estimate protensity and to distinguish the relative lengths of short tones. We also examined whether there is a correlation between a person's degree of disfluency and the ability to measure protensity or judge the relative lengths of short tones. Twenty stuttering and 20 nonstuttering adults were given the Duration Pattern Sequence Test. They were also asked to estimate the lengths of 8 tones and silent intervals. A negative correlation was found between degree of disfluency and ability to determine the relative lengths of short tones. A positive correlation was found between degree of disfluency and length of protensity estimates.
