Fluent speakers and stutterer's increased voice level were analyzed in response to voice-delayed auditory feedback, an Edinburgh masker, and white noise. These results are used to assess auditory feedback monitoring accounts of speech behavior of fluent speakers and stutterers with some implications for the treatment of stuttering. (37 references)…

This study analyzed a conversational speech sample from 10 preschool children stuttering for a year or less and age- and sex-matched nonstuttering children. Analysis indicated no significant between-group differences for either the duration of acoustically measured sound/syllable repetitions and sound prolongations or the number of repeated units…

This letter to the editor comments on a 1998 article by J. S. Yaruss which proposed that classification of stuttering be adopted to foster improvement in basic understanding. The article is critiqued as failing to recognize the two major components of a stuttering event and for the author's definitions of impairment and disability as applied to…

A review of research on brain imaging of developmental stuttering concludes that findings increasingly point to a failure of normal temporal lobe activation during speech that may either contribute to (or is the result of) a breakdown in the sequencing of processing among premotor regions implicated in phonologic planning. (Contains references.)…

This study was intended to replicate and extend previous findings that (a) during fluent speech persons who stutter (PS) and those who do not (NS) differ in their vocal tract closing movements (L. Max, A. J. Caruso, & V. L. Gracco, 2003) and (b) ratios relating lip and tongue speed to jaw speed increase with stuttering severity (M. D. McClean & C.…

The purpose of this investigation was to assess the influence of lexical/semantic priming on the speech reaction time of young children who do and do not stutter during a picture-naming task. Participants were 23 children who stutter, age-matched ([+ or -] 4 months) to 23 children who do not stutter, ranging in age from 3;0 (years;months) to 5;11.…

Background: Speech and language therapists treating children who stutter appear to be assigned a difficult task. Natural spontaneous remission accounts for approximately 60-80% of all children recovering from stuttering. Despite our best efforts, no protocol has ever shown its effectiveness separate from natural recovery rates (i.e. 60-80%).…

This study investigated the experiences of adults who have completed a course of therapy for stammering. The objective was to inform clinicians about the effect of therapy by listening to the client's own account of the experience after they had been discharged from therapy. The study involved individuals discussing their experiences and their…

The purpose of this study was to investigate the relation between stuttering and a range of variables of possible relevance, with the main focus on neuromuscular reactivity, and anxiety. The explorative analysis also included temperament, biochemical variables, heredity, preonset lesions, and altered auditory feedback (AAF). An increased level of…

Knowledge of variables that predict treatment time is of benefit in deciding when to start treatment for early stuttering. To date, the only variable clearly related to treatment time with the Lidcombe Program is pre-treatment stuttering frequency. Previous studies have shown that children whose stuttering is more severe take longer to complete…

Background: In recent years, the importance of a multimodal approach to the assessment of the person who stutters (PWS) has become increasingly recognized. The Behavior Assessment Battery (BAB), which is a normed test procedure developed by G. Brutten, makes it possible to assess the multidimensional facets of this disorder. The emotional and…

There is a need to evaluate the effectiveness of stuttering treatment programs delivered in domestic and international contexts and to determine if treatment delivered internationally is culturally sensitive. Evaluation of the effectiveness of the ISTAR Comprehensive Stuttering Program (CSP) within and across client groups from the Netherlands and…

Expectancy in stuttering was investigated with 10 young adult stutterers under conditions that approximate more closely than in previous work the circumstances and mode in which expectancy is purported to operate. (Author/GW)
