Eighteen adult listeners assessed whether stuttering samples were authentic or simulated. Results support the concepts that the production of stuttered and nonstuttered speech disruptions are experienced as being qualitatively different; only stutterers can validly recognize the difference, and only when it occurs; stuttering is a…

Changes in upper/lower lip integrated electromyographic (IEMG) amplitude and temporal measures related to linguistic factors known for their influence on stuttering were investigated in 12 male Dutch nonstutterers. Findings indicated that production of stressed, vowel-rounding gestures of words in initial position, longer words, and words in…

Unsophisticated raters judged speech naturalness and stuttering severity in audio-only and audiovisual presentations of speech samples. For stutterer samples, raters judged the audiovisual presentation more unnatural than the audio presentation, but for the nonstutterer samples, there was no difference. Stuttering severity ratings did not differ…

Sound/syllable repetitions of 13 young children who stutter were acoustically analyzed to identify differences in second formant (F2) transitions between the stuttered and nonstuttered portions of the words. Findings indicated no significant differences in the frequency of occurrence of missing or atypical F2 transitions for young children at…

Eight children (ages 6-10) were given a simplified treatment program for stuttering which included awareness training, training a response incompatible with stuttering, and social support. The home treatment program was effective in reducing stuttering to less than 3% for all subjects. Maintenance of effects was seen at 10-13 months posttreatment.…

Examines the prevalence of nervous habits, tics, and stuttering and the relationship between these behaviors and general anxiety in college students (n=256). Participants completed self-report measures of general anxiety and somatic awareness. Relationships were found between number of nervous habits and self-reported awareness of bodily…

A study investigated voice onset time in voiced stop consonants under varying constraints. Under variation of rate, lexical stress location and location of key words beginning with voiced stops, the three adult stutterers realized voiced stops by voicing before release, whereas controls realized voiced stops by voicing following the release.…

The purpose of this study was to investigate the nature of recovery from stuttering based on the experiences of adults who recovered without treatment. Using a semi-structured, open-ended interview format, 15 speakers verified as persons who recovered without treatment were asked to describe their status as everyday speakers. Seven speakers…

Purpose: To investigate the effect of repeated exposure to delayed auditory feedback (DAF) during a 3-month period outside a clinical environment and with only minimal clinical guidance on speech fluency in people who stutter. Method: A pretest-post-test design was used with repeated exposure to DAF during 3 months as the independent variable.…

The study investigated: (1) whether the mothers of young stuttering children differ from the mothers of young normally disfluent children in their verbal interaction patterns during free play with their children; and (2) whether disfluency in young children is related systematically to the type of speech act expressed. Four preschoolers and their…

The study explored the verbal and nonverbal conversational competency of five adult males who exhibited fluency disorders. Five subject/interactant videotaped conversational interactions were analyzed utilizing an INter-REActive Learning (INREAL) Model analysis format. Descriptive individual and composite profiles resulting from trained raters'…

The study examined inadequate behaviors of Japanese mothers with their stuttering children. Video tape recordings of playing situations of five stuttering children (ages 3-5) and their mothers and five non-stuttering children and their mothers were evaluated using two rating check lists. Results found differences in the behaviors of the two groups…

The report summarizes a project investigating effects of biofeedback on nine secondary students with speech problems including stuttering, vocal nodules, articulation problems, and cerebral palsy. It is explained that a portable electromyograph was used to give the students immediate visual and/or auditory feedback. Results listed include that Ss…

Speech and hearing screening conducted with 136 penitentiary inmates revealed normal prevalence figures for articulation and fluency disorders but appreciably higher prevalence for voice and hearing disorders. Possible correlations with age levels 21-25 years and educational levels 0-6 years were noted. (Author/CL)

Disfluency characteristics of 36 nonstuttering boys aged two, four, and six years were analyzed from tape recorded speech samples made during free play within neutral and stress situations. Comparisons of frequency of disfluency were made among the different ages within each situation and between the neutral and stress situations. (Author)
