Perceptual, Acoustic, And Kinematic Effects Of Sentence-Initial, Single-Phoneme Prolongation In People Who Do And Do Not Stutter, Darrell Sharp Matthews
Perceptual, Acoustic, And Kinematic Effects Of Sentence-Initial, Single-Phoneme Prolongation In People Who Do And Do Not Stutter, Darrell Sharp Matthews
Theses and Dissertations
This study examined a sentence-initial one-second sound prolongation as a possible fluency-inducing condition in people who stutter. The effects of this prolongation technique on the single sentence utterances of five people who stutter (PWS) and five age- and gender-matched controls were investigated. Variables tested included stuttering percentages, speaking rate, duration of phonated intervals, and correlation between upper lip and lower lip/jaw. Results showed a non-significant trend for less stuttering to occur when participants used the prolongation technique. Significant findings included longer durations of phonated intervals and more negatively correlated upper- and lower-lip movements during the prolongation condition. Rate of speech …

Investigating Motor Training In People Who Stutter Using Fnirs, Kristen Michelle Johnson
Masters Theses, 2010-2019
This pilot study investigated motor learning and neuroplasticity in persons who do and do not stutter before and after participation in a phonation onset training protocol. Outcomes included phonation onset time and percent change in oxygenation level of hemoglobin using fNIRS in prescribed brain areas as a result of training. The authors hypothesized that people who stutter (PWS) would 1) exhibit a breakdown in auditory perception to motor production interactions, 2) demonstrate a difference in the way in which they perceive and learn motor information compared to someone who does not stutter (nPWS), and 3) exhibit reduced brain activity correlations …
Self-Modeling As An Intervention For Stuttering In Elementary Students, Jason Northrup
Self-Modeling As An Intervention For Stuttering In Elementary Students, Jason Northrup
Legacy Theses & Dissertations (2009 - 2024)
Stuttering is a disorder involving disruptions and disfluencies in speech that impacts overall communication and affects approximately 1% of the population. In addition to speech disfluency, stuttering is often related to physical tension, embarrassment, fear, anxiety, and other negative social-emotional problems, especially for children and adolescents. Fortunately, research indicates that stuttering can be alleviated before becoming more advanced and complex as individuals enter adolescence and adulthood. Self-modeling, an intervention that involves individuals watching themselves engage in exemplary behavior, appears to be particularly effective for individuals who stutter and can be implemented in a school setting. The purpose of this study …
