Background: In recent years, there has been increased identification of disfluencies in individuals with autism, but limited examination of disfluencies in the school-age range of this population. We currently lack information about whether the disfluencies of children with autism represent concomitant stuttering, normal disfluency, excessive…

Background: Metronome-paced speech results in the elimination, or substantial reduction, of stuttering moments. The cause of fluency during this fluency-inducing condition is unknown. Several investigations have reported changes in speech pattern characteristics from a control condition to a metronome-paced speech condition, but failure to control…

Background: Treatment of adolescents who stutter is an under-researched area that would benefit from greater attention. Aims: To investigate whether an intensive treatment programme for older teenagers who stutter, aged over 16 years of age, is effective in reducing overt and covert aspects of stuttering. Methods & Procedures: A…

Background: Overt stuttering is inhibited by approximately 80% when people who stutter read aloud as they hear an altered form of their speech feedback to them. However, levels of stuttering inhibition vary from 60% to 100% depending on speaking situation and signal presentation. For example, binaural presentations of delayed auditory feedback…

Purpose: The Lidcombe Program is an operant treatment for early stuttering shown with meta-analysis to have a favorable odds ratio. However, many clients are unable to access the treatment because of distance and lifestyle factors. In this Phase I trial, we explored the potential efficacy, practicality, and viability of an Internet webcam Lidcombe…

Purpose: Percentage of syllables stuttered (%SS) and severity rating (SR) scales are measures in common use to quantify stuttering severity and its changes during basic and clinical research conditions. However, their reliability has not been assessed with indices measuring both relative and absolute reliability. This study was designed to provide…

Purpose: The authors of this quasi-experimental design study explored the effect of an educational documentary video that presented factual and emotional aspects of stuttering on changing attitudes toward stuttering of preservice trainees and in-service public school teachers in Kuwait. Method: Participants were 99 preservice trainees (48 control,…

Background: At present, percent syllables stuttered (%SS) is the gold standard outcome measure for behavioural stuttering treatment research. However, ordinal severity rating (SR) procedures have some inherent advantages over that method. Aims: To establish the relationship between Clinician %SS, Clinician SR and self-reported Speaker SR. To…

Purpose: Individuals who stutter show sensorimotor deficiencies in speech and nonspeech movements. For the mandibular system, the authors dissociated the sense of kinesthesia from the efferent control component to examine whether kinesthetic integrity itself is compromised in stuttering or whether deficiencies occur only when generating motor…

Purpose: Stuttering varies between and within speaking situations. In this study, the authors used statistical process control charts with 10 case studies to investigate variability of stuttering frequency. Method: Participants were 10 adults who stutter. The authors counted the percentage of syllables stuttered (%SS) for segments of their speech…

The purpose of this article is to discuss definitional and measurement issues as well as empirical evidence regarding temperament, especially with regard to children's (a)typical speech and language development. Although all ages are considered, there is a predominant focus on children. Evidence from considerable empirical research lends support…

Purpose: This study examined the effect of speech rate on phonated intervals (PIs), in order to test whether a reduction in the frequency of short PIs is an important part of the fluency-inducing mechanism of chorus reading. The influence of speech rate on stuttering frequency, speaker-judged speech effort, and listener-judged naturalness was also…

The purpose of this study was to examine college students' perspectives on dating a person who stutters (PWS). One hundred and thirty-two college students responded to a 19-item survey questionnaire. Survey items included questions about participants' familiarity with persons who stutter, family and/or personal history of stuttering,…

Nonword repetition and phoneme elision represent the combined influence of several speech and language processes. In the present study we investigated nonword repetition and phoneme elision performance in school-age children who stutter (CWS) and children who do not stutter (CNS). Participants were 14 CWS (mean = 11.7 years, SD = 2.1 years) and…

Background: People who stutter often experience negative judgments and reactions to their stuttering from the nonstuttering majority. Many are stigmatized because of their stuttering and threatened with social exclusion, placing them at risk for compromised quality of life. Aims: The purpose of this investigation was to measure public attitudes…
