We investigated the role of delayed cerebral maturation, hemisphere asymmetry and regional differences in children with stuttering and healthy controls during resting state and hyperventilation, using conventional EEG techniques and quantitative EEG (QEEG) analysis. This cross-sectional case control study included 26 children with stuttering and…

Purpose: The purpose of this study was to investigate chorus reading's (CR's) effect on speech effort during oral reading by adult stuttering speakers and control participants. The effect of a speech effort measurement highlighting strategy was also investigated. Method: Twelve persistent stuttering (PS) adults and 12 normally fluent control…

Purpose: The purpose of this study was to develop guidelines for the statistical analysis of percentage of syllables stuttered (%SS) data in stuttering research. Method; Data on %SS from various independent sources were used to develop a statistical model to describe this type of data. On the basis of this model, %SS data were simulated with…

This leaflet provides a summary of research and recent advances in understanding stuttering. Stuttering is defined as a disorder in which the rhythmic flow of speech is frequently disrupted by repetitions of sounds or syllables. The leaflet outlines possible causes of stuttering, methods of measurement of fluency and work on a uniform method of…

To determine whether or not a modified delayed auditory feedback would smooth the speech pattern and increase fluency in stutterers, eight severe stutterers were given individual 10 to 40 hour speech sessions. Feedback was delayed by .2 seconds, the rate of speech controlled by the experimenter, and speech patterns were smoothed by prolonging…

Stuttering is explained to be a time and rhythm speech disorder. The overview in outline form on stuttering notes the nature of the disorder, primary and secondary types, incidence, age of onset, stutterer's profile, intelligence, psychological traits, physiological traits, sociological traits, predisposing conditions, precipitating conditions,…

Twenty-five male stutterers and 25 male non-stutterers (5-13 years old) matched by age and speaking task, read or recited under normal and 113-, 226-, 306-, 413-, 520-msec. delayed auditory feedback conditions. (Author)

Described is a procedure for the reduction of stuttering behavior by means of reality confrontations in structure verbal exchanges, which has been used by the author as treatment with over 200 adolescent stutterers. (Author/IM)

A study involving 14 stutterers (mean age 20.7 years) was conducted to determine the effect of sentence length on the frequency of stuttering. (Author/SBH)
