Abstract

The purpose of the present study was to investigate the impact of utterance length and syntactic complexity on the speech mot-or stability of adults who stutter Lower lip movement was recorded from 8 adults who stutter and 8normally fluent controls. They produced a target phrase in isolation (baseline condition) and the same phrase embedded in utterances of increased length and/or increased syntactic complexity The spatiotemporal index (STI) was used to quantify the stability of lower lip movements across multiple repetitions of the target phrase. Results indicated: (a) Adults who stutter demonstrated higher overall STI values than normally fluent adults across allexperimental conditions, indicating decreased speech motor stability; (b) the speech motor stability of normally fluent adults was not affected by increasing syntactic complexity, but the speech motor stability of adults whostutter decreased when the stimuli were more complex; (c) increasing the length of the target utterance (without increasing syntactic complexity) didnot affect the speech motor stability of either speaker group These results indicate that language formulation processes may affect speech productionprocesses and that the speech motor systems of adults who stutter may be especially susceptible to the linguistic demands required to produce a more complex utterance. The present findings, therefore, support the hypothesis that linguistic complexity is one Factor that contributes to the disruptions of speech motor stability characteristic of stuttering.
