Purpose: Previous studies have shown that individuals who stutter exhibit abnormal speech perception in addition to disfluent production as compared with their nonstuttering peers. This study investigated whether adult Chinese-speaking stutterers are still able to use knowledge of statistical regularities embedded in their native language to…

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…

Purpose: The purpose of this study was to examine (a) the role of neighborhood density (number of words that are phonologically similar to a target word) and frequency variables on the stuttering-like disfluencies of preschool children who stutter, and (b) whether these variables have an effect on the type of stuttering-like disfluency produced.…

A study of children who stutter (n=12), who have recovered early from stuttering (n=12), and who recovered later from stuttering (n=12) compared the phonological characteristics of the three groups with a control group. Results indicated that poor phonological ability in the early stage of stuttering appeared to be a contributing factor to the…

Two experiments used a magnitude estimation paradigm to test whether perception of disfluency is a function of whether the speaker and the listener stutter or do not stutter. Utterances produced by people who stutter were judged as "less fluent," and, critically, this held for apparently fluent utterances as well as for utterances…

One of a series of semiannual reports, this publication contains 18 articles which report the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Articles and their authors are as follows: "Phonology and Beginning Reading Revisited (Isabelle Y. Liberman); "The Role of…

The purpose of this study was to assess the influence of phonological priming on the speech reaction time (SRT) of children who do (CWS) and who do not (CWNS) stutter during a picture-naming task. Participants were eighteen 3-5-year-old CWS (M = 50.67 months, SD= 11.83 months), matched in age and gender with 18 CWNS (M = 49.44 months, SD = 10.22…

One of a series of semi-annual reports, this publication contains 25 articles which report the status and progress of studies on the nature of speech, instruments for its investigation, and practical applications. Articles are as follows: "Acoustic Shards, Perceptual Glue" (Robert E. Remez and Philip E. Rubin); "F0 Gives Voicing…
