Purpose: Previous studies have shown that individuals who stutter exhibit abnormal speech perception in addition to disfluent production as compared with their nonstuttering peers. This study investigated whether adult Chinese-speaking stutterers are still able to use knowledge of statistical regularities embedded in their native language to…

Purpose: The purpose of this study was to examine the impact of self-disclosure and strategies for communication competence on perceptual ratings and performance evaluations of undergraduate students who do and do not stutter by professors who require oral presentations. Method: Two hundred thirty-eight college instructors who require oral…

Purpose: The purpose of this study was to examine the perceptual ratings and performance evaluations of students who do and do not stutter by professors who require oral presentations. Additionally, this study sought to investigate the influence of behaviors related to communication competence on perceptual and evaluative ratings. Method: One…

Purpose: The primary purpose of this study was to describe the frequency and types of speech disfluencies that are produced by bilingual Spanish-English (SE) speaking children who do not stutter. The secondary purpose was to determine whether their disfluent speech is mediated by language dominance and/or language produced. Method: Spanish and…

Purpose: The objective of this research was to compare the number and types of grammatical and non-grammatical silent pauses presented by stutterers and subjects with Asperger syndrome in their narratives. Method: Ten children who stutter and four participants with Asperger syndrome (mean ages of both groups 10 years) were assessed at the Speech…

Purpose: Chronic disorder can impose a significant negative mental health burden. This research was conducted to explore factors that may protect people from the adversity of chronic stuttering. Method: The study employed a population group cohort design. Participants included 200 adults who have stuttered since childhood, and the sample was…

Measures of language sample length (in c-units) and morphological, syntactic, and narrative abilities were obtained from oral narrative transcripts of 22 children who stutter and 22 children who do not stutter; participants attended kindergarten, first, and second grades. A two-way MANOVA yielded significant main effects for grade, with…

This study with 10 adults who stutter and 10 nonstuttering controls completed speech, orofacial nonspeech, and finger isochronous rhythmic timing tasks to investigate the role of timing in stuttering. Findings extend growing evidence that stuttering individuals do not differ from nonstuttering individuals in the ability to generate temporal…

Pressure buildup patterns preceding the onset of phonation were studied in 573 fluent utterances of 10 stutterers and in 552 utterances of 7 controls. Stutterers evidenced deviant patterns of subglottal pressure buildup and abrupt voice onsets more often than did controls; occurrence of jitter and shimmer did not differ significantly. (Author/JDD)
