The purpose of this study was to assess clause, syllable, and response latency characteristics of conversational utterances produced by children who stutter. Subjects were 14 boys who stutter (M age = 52.07 months; SD = 9.02 months) and 14 boys who do not stutter (M age = 51.93 months; SD = 8.55 months). Selected aspects of speech fluency, clause and(More)
Selected characteristics of disfluent conversational utterances with and without disfluency clusters were examined in 14 children who stutter (CWS) and 14 children who do not stutter (CWNS). For CWS, utterances with disfluency clusters contained significantly more syllables and clausal constituents than disfluent utterances without clusters, which, in turn,(More)
UNLABELLED Diadochokinetic (DDK) rates are commonly assessed in children with speech-language disorders, even though the implications of fast or slow DDK rates are not clear. This study explored the possibility that the accuracy and fluency of DDK productions may provide a meaningful supplement to traditional measures of DDK rate. Participants were 15 boys,(More)
School-aged children who stutter often present concomitant impairments in articulation and language that can complicate treatment. In this article, a framework is offered for designing intervention programs for such children. It is stressed that clinicians must first identify clinical priorities by determining the severity of the impairments, their impact(More)
The present study examined language and fluency characteristics of single-utterance (SU) and multiple-utterance (MU) conversational turns produced by 15 preschoolers who stutter and 15 age- and sex-matched preschoolers who do not stutter. Participants conversed with a parent in a play seating. Each interaction was videotaped and the participants' resultant(More)
UNLABELLED Past research has shown that adults who stutter tend to be slower than adults who do not stutter at initiating various speech-like movements, nonsense syllables, words, short phrases, and simple sentences. The present study sought to extend this research by examining the effect that syntactic structure has upon stutterers' and nonstutterers'(More)
PURPOSE To compare articulation and speech rates of school-aged children who do and do not stutter across sentence priming, structured conversation, and narration tasks and to determine factors that predict children's speech and articulation rates. METHOD 34 children who stutter (CWS) and 34 age- and gender-matched children who do not stutter (CWNS) were(More)
PURPOSE This study was designed to (a) compare the speech fluency of school-age children who do and do not stutter (CWS and CWNS, respectively) within 2 standard diagnostic speaking contexts (conversation and narration) while also controlling for speaking topic, and (b) examine the extent to which children's performance on such discourse tasks is affected(More)
UNLABELLED The purpose of this study was to examine the extent to which adults who do not stutter can predict communication-related attitudes of adults who do stutter. 40 participants (mean age of 22.5 years) evaluated speech samples from an adult with mild stuttering and an adult with severe stuttering via audio-only (n=20) or audio-visual (n=20) modes to(More)
