Surface electrodes were used to describe the perioral reflexes in seven stutterers and five nonstutterers and electromyographic (EMG) recordings were obtained at electrode sites associated with the orbicularis oris inferior muscle and the depressor labia inferior muscle. A difference was noted in the pattern of reflex response between the two…

Speech analysis of 10 two- to three-year-olds diagnosed by parents as having begun stuttering and 10 matched normally speaking children indicated that stutterers were three times more disfluent than nonstutterers. Part-word repetitions and sound prolongations were found to distinguish the two groups significantly. (Author/CL)

Simple reaction times of 13 stuttering and 13 nonstuttering children (8-12 years old) matched for age, sex, and handedness were compared in experimental conditions requiring button-pressing responses and nonspeech and speech-like responses. Results of the forefinger data suggested that stuttering is not related to an organically based overall…

Background: Bloodstein reviewed hundreds of studies that investigated the efficacy of therapeutic protocols for ameliorating the stuttering syndrome. Surprisingly, almost all were effective in significantly reducing overtly perceptible behaviours such as repetitions and prolongations of speech sounds. These results seem highly improbable…

Background: There will always be a place for stuttering treatments designed to eliminate or reduce stuttered speech. When those treatments are required, direct speech measures of treatment process and outcome are needed in clinical practice. Aims: Based on the contents of published clinical trials of such treatments, three "core" measures of…

The purpose of this study was to explore whether stuttering severity or therapy involvement had an effect on the attitudes that individuals who do not stutter reported towards people who stutter (PWS). Two hundred and sixty (260) university students participated in this study. Direct survey procedures consisting of a 25-item semantic differential…

Two studies illustrate the utility of listener ratings of speech naturalness for measuring and modifying speech naturalness during stuttering therapy. The program involved five adolescent stutterers receiving an intensive treatment incorporating a prolonged speech procedure. Results showed that speech naturalness ratings could be modified toward a…

Results of a study involving 76 stutterers and 76 nonstutterers (seven to 15 years old) included (1) a right- ear preference for both groups; (2) differences in dichotic stuttering and nonstuttering Ss; and (3) a relationship between stuttering severity and hemispheric dominance dependency on manner of data analysis.

Electroglottographic (EGG) and acoustic waveforms of the first few glottal pulses of voicing were monitored and voice onset time (VOT) measured during an adaptation task performed by adult stutterers and controls. Fluent utterances of stutterers resembled those of controls. After dysfluencies, however, the EGG signal increased gradually, lending…

During the silent reading of a 320-word passage, the eye movements of 22 grade school stutters and 22 nonstutters were recorded by means of a computer-controlled eye-marker. Frame-by-frame analysis of the recordings revealed that the stuttering children displayed significantly more eye fixations and eye regressions than the nonstuttering children.…

Results indicated that both monolingual and bilingual stutterers were more dysfluent on voiceless consonants; the bilingual stutterers stuttered more on the nasal sounds; and phonetic influences on stuttering might be dependent on the number of languages spoken as well as specific language in which the effects were observed. (Author/CL)

The relationship of syllabic stress, word onsets, and stuttering was examined in selected words within a set of 40 controlled sentences containing bisyllabic words with contrastive stress. Among findings were that participants displayed a greater tendency to stutter on word onsets than stressed syllables or other subsequent syllables. (Author/DB)

This study examined whether stuttering speakers (N=10) differed from fluent speakers in relations between the neural control systems for speech and life support. It concluded that in some stuttering speakers the relations between respiratory controllers are atypical, but that high participation by the high frequency oscillation-producing circuitry…

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…
