From a corpus of over 47,000 spontaneous utterances from four nonstuttering preschool children who were beginning to use syntax, 4,881 multiword, disfluent utterances were identified. Semantic-syntactic structures were identified among the disfluent multiword utterances, and differences in frequency of structures were examined. (Author)

Linguistic processing by the left and right cerebral hemispheres was investigated in 10 adult stutterers and 10 matched nonstutterers. The stuttering group exhibited a left visual field efficiency or right hemisphere preference for this task and were slower in both vocal and manual reaction times. (Author/CL)

The speech of five stutterers ranging in age from 3 years, 10 months to 5 years, 7 months was analyzed to determine the types of loci of stutterings. The results related to the hypothesis that early stuttering represents mainly a type of difficulty in either the formulaton or the execution of syntactic units. (Author)

Transcriptions of the speech of 16 adolescent and young adult stutterers and 16 nonstutterers were rated by 12 fourth and fifth year speech/language pathology students as a sample from a stutterer or a nonstutterer. (PHR)

Fourteen individuals who stutter and 14 nonstuttering individuals were assessed for the magnitude of their eye blink responses to noise bursts as a measure of temperament. Eye blink response to the initial noise burst and the mean of 10 responses were significantly greater for the stuttering group. Additionally, the Nervous subscale of the…

The study found no significant trends in the change of acoustical durations of stutter- and disfluency-free speech from readings in an adaptation series with four adapting, four nonadapting, and four nonstuttering subjects (all young adults). Findings suggest that adaptation of stuttering and other fluency-inducing conditions are a result of…

When eight psychiatric adults with stuttering problems were evaluated on seven speech tasks, 12 percent of their total subject output was nonfluencies. Results are analyzed in terms of: tasks most frequently involving nonfluencies; types of nonfluencies; and relative frequency of nonfluencies occurring on words in the beginning, middle, or end of…

This study of 14 school-age children who stuttered found that the average duration of stuttering was approximately three-quarters of a second and was not correlated with age, length of post-onset interval, or frequency of speech disfluency. Stuttering duration may be related to amount of sound prolongations as well as articulatory rate during…

This study investigated the effect of auditory feedback alterations on stuttering frequency of 10 adults. At high speech rates, stuttering frequency was significantly reduced under delayed auditory feedback, frequency altered feedback, and a combination. There were no significant differences among the altered feedback conditions. (Author/SW)

Contact after 6 to 8 years with families of 21 children who were diagnosed as stuttering but did not receive fluency intervention services found that almost all subjects still had a stuttering problem. Results dispute the high spontaneous recovery rates reported in the literature and support the value of early intervention. (Author/DB)

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…

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…
