Formant Frequency Transitions In The Fluent Speech Of Adults Who Do And Do Not Stutter: Testing The Over-Reliance On Feedback Hypothesis, Kaitlin Arnold

Masters Theses

A recent theory proposed by Civier and colleagues (Civer et al. 2010; Civer et al. 2013) developed a model of stuttering that implicates a faulty feedforward control system. The hypothesis suggests that stuttering results from relying too heavily on sensory feedback to guide speech movements. An overreliance on sensory feedback would result in subtle anomalies in fluent speech (such as slowed articulatory transitions) as well as overt stuttering behaviors (such as sound repetitions). The present study tested this general hypothesis by comparing articulatory transition rates of adults who do and do not stutter across casual and fast speech rates. Participants …

College Professors’ And Students’ Perceptions Toward College Students Who Stutter, Patricia N. Chastain

Honors Theses

Research on stuttering has reflected the perceptions of speech-language pathologists (Swartz, Gabel & Irani, 2009; Crichton-Smith, Wright & Stackhouse, 2003; Cooper & Cooper, 1996; Kalinowski, Armson, J., Stuart, A., & Lerman, J. W., 1993; Daniels, Panico, & Sudhoolt, 2011), students (Mayo & Mayo, 2013; Dorsey & Guenther, 2000), and professors (Dorsey & Guenther, 2000; Silverman, 1990; Ruscello et al., 1990) toward people who stutter (PWS). The findings of the aforementioned studies indicated there is neither a wholly positive or negative attitudinal trend in the perceptions towards PWS within or across groups. Only one study was conducted (15 years ago) that …

Fnirs Measures Of Prefrontal Cortex Lateralization During Stuttered And Fluency-Enhanced Speech In Adults Who Stutter, Danra M. Kazenski

Graduate College Dissertations and Theses

The present study compared lateralization of cortical activation patterns in the prefrontal cortex (PFC) of adults who stutter (AWS) and typical speakers (TS) as measured with functional near infrared spectroscopy (fNIRS) in habitual and fluency-enhanced speaking conditions.

Participants were AWS (n = 11) and gender- and age-matched TS (n = 11) who completed speaking tasks in three condition blocks: (1) habitual speech using no speaking strategy (2) prolonged speech after receiving short-term training in fluency-shaping strategy-use (3) syllable-timed speech after being trained to speak in rhythm with a metronome at 92 beats per minute.

The three primary dependent variables were …

Online Communities For People Who Stutter: An Ethnographic Study Of A Facebook Social Networking Support Group, Erik X. Raj

Wayne State University Dissertations

The purpose of this study was to explore the experiences of people who stutter who digitally connect and share with other people who stutter on a social networking site, specifically Facebook. This study used a qualitative, ethnographic approach to gain insight from members of a private Facebook group for people who stutter and to collect their opinions as to whether an online community was a beneficial means of obtaining psychosocial support from other people who stutter. The primary investigator collected textual data and artifacts from 3 months of Facebook group postings, semi-structured interviews with 7 of the Facebook group members, …

Identifying Speech-Language Pathologists' Current Perceptions And Practice Patterns, Mary Margaret Griffith

Online Theses and Dissertations

A web-based survey was collected and analyzed from 39 speech-language pathologists (SLP) contacted through the American Speech-Language-Hearing Association's (ASHA) Special Interest Groups #2 and #4 as well as members of the American Board of Fluency and Fluency Disorders (ABFFD) via email regarding their current perceptions and clinical practice patterns with individuals with neurogenic and psychogenic stuttering. Participants reported using a battery of assessments and a variety of treatment approaches to diagnose neurogenic and psychogenic stuttering in addition to traditional fluency assessments and fluency enhancing techniques. Participants rated themselves as having more knowledge and experience with neurogenic stuttering than psychogenic stuttering. …

Anticipatory Coarticulation And Stability Of Speech In Typically Fluent Speakers And People Who Stutter Across The Lifespan: An Ultrasound Study, Alissa Joy Belmont

USF Tampa Graduate Theses and Dissertations

This study uses ultrasound to image onset velar stop consonant articulation in words. By examining tongue body placement, the extent of velar closure variation across vowel contexts provides for the measurement of anticipatory coarticulation while productions within the same vowel context provide measurement of extent of token-to-token variation. Articulate Assistant Advanced 2.0 software was used to semi-automatically generate midsagittal tongue contours at the initial point of maximum velar closure and was used to fit each contour to a curved spline. Patterns of lingual coarticulation and measures of speech motor stability, based on curve-to-curve distance (Zharkova, Hewlett, & Hardcastle, 2011), are …

Outcomes Of A Combined Mindfulness, Stuttering Modification, And Fluency Shaping Intervention For Children Who Stutter, Jennifer Kordell

USF Tampa Graduate Theses and Dissertations

A week-long intervention for five school-age children who stutter was implemented using techniques of fluency shaping, stuttering management, and mindfulness training. The purpose of this study was to investigate if children who stutter stuttered less frequently, stuttered with less struggle, and demonstrated changes in mindfulness measures after the completion of this week-long intervention. Pre- to post-treatment measures were analyzed by individual and group-level results. A comparative analysis between reading and narrative tasks was also performed. Findings indicate that three out of five children reduced the total number of disfluencies during the reading task, and two children reduced this total during …
