Durational, Proportionate, And Absolute Frequency Characteristics Of Disfluencies: A Longitudinal Study Regarding Persistence And Recovery, Rebecca Throneburg, Ehud Yairi

Faculty Research and Creative Activity

The main objective of this study was to investigate developmental aspects of disfluencies over time as stuttering persists or ameliorates for 2 groups of preschool age children who stutter. Results indicated that the frequency, type, and duration of disfluencies remained relatively constant instead of increasing as expected in the persistent group over a 3-year period. In contrast, the recovered group's initially higher frequency of disfluency decreased over time, as did their number of repetition units and proportion of disrhythmic phonations, while the duration of silent intervals between repetition units and proportion of monosyllabic word repetitions increased.

A Comparison Of Listener And Speaker Perception Of Stuttering Events, Anne Jocelyn Schagen

Dissertations and Theses

Stuttering identification, measurement, research, and treatment have for many years had their basis in listener judgment of stuttering, but the covert aspects of stuttering are not behaviorally observable, and inter-rater reliability has repeatedly been shown to be low. Perkins (1990) has emphasized the importance of consulting the speaker for the most reliable perspective on stuttering identification. The question raised in this study is whether there is a significant correlation between stuttering identification based upon internal perception by a speaker who stutters, and identification based upon external perception of listeners, with points of inter-rater disagreement removed. Six adult males, aged 18 …

A Comparison Of Speech Onset Latencies Between Persons Who Stutter And Persons Who Do Not Stutter Across Varied Phonological Priming Conditions, Brian Joseff Riffel

Dissertations and Theses

A recent theory of stuttering, the "Covert Repair Hypothesis of Disfluencies" (Kolk & Postma, in press; Postma & Kolk, 1992, 1993), accounts for the difference between persons who stutter (PWS) and persons who do not stutter (PWNS) by concluding that PWS are slower than PWNS in their phonological encoding abilities. This belief is supported through experimental studies by Bosshardt (1990) and Postma et al (1990), both of which found PWS to be slower than PWNS in silent reading tasks. In addition, Wijnen and Boers (1994) found that PWS demonstrate longer speech onset latencies than PWNS at baseline, but then approximate …

Relation Between Phonologic Difficulty And The Occurrence Of Disfluencies In The Early Stage Of Stuttering, Rebecca Throneburg, Ehud Yairi, Elaine Paden

Faculty Research and Creative Activity

People who stutter, especially children, have often been reported to exhibit a wide range of concomitant communication problems including articulation and phonologic deficiencies. This study investigated the relation between the phonologic difficulty of words and the point at which stuttering-like disfluencies occurred in the speech of preschool children identified as having a stuttering problem (n = 24). The children were divided into subgroups according to stuttering severity and phonologic ability. A spontaneous speech sample of approximately 1,000 words was tape-recorded from each child, and perceived disfluencies were identified. The phonologic difficulty of each word on which there was a stuttering-like …

The Early Months Of Stuttering: A Developmental Study, Rebecca Throneburg, Ehud Yairi, Nicoline Ambrose

Faculty Research and Creative Activity

Objective data on the development of stuttering during its first several months are sparse. Such a deficit is due to parents' tendency to postpone professional consultation regarding early stuttering until later in the course of the disorder and to a lack of longitudinal studies beginning close to onset. This report presents information on a rare group of 16 preschool subjects who were evaluated within several weeks after stuttering onset and followed for 6 months using multiple measures. The findings show that often early stuttering takes on a moderate-to-severe form. Substantial changes occurred, however, during the 6 months of the study, …

An Analysis Of The Relationship Between The Degree Of Maintained Fluency Improvement Of Former Portland State University Stuttering Clients And The Overall Language Themes They Used, Karen F. Mathew

Dissertations and Theses

This research examined the relationship between the degree of maintained fluency improvement and the type of language used to respond to questions directly and indirectly related to speaking behavior. The subjects included sixteen former Portland State University stuttering clients who had participated in the Ginter (1979) study on fluency maintenance. The subjects responded to a thirteen item questionnaire dealing with themselves and their speaking behavior. Responses were recorded on the Modified Thematic Analysis Form developed by this examiner and analyzed according to guidelines set down by Stone and Casteel (1975) and this examiner.

An Electromyographic Comparison Of Muscle Action Potentials Of Adult Stutterers During Signalled Expectancy And Non-Expectancy To Stutter, Catherine Ann Miller

Dissertations and Theses

The purpose of this study was to determine what relationship (if any) exists between signalled expectancy to stutter and a significant increase in muscle action potential in adults as measured by electromyography (EMG).

An Investigation Of Client Fluency Maintenance Between 1972-1977 At Portland State University, Pricilla Lynn Ginter

Dissertations and Theses

The use of so many different therapeutic approaches to stuttering raises frequent questions about methodology and treatment. Confidence in a methodology and treatment approach depends upon follow-up research conducted with systemic analysis of the individuals prior to treatment and following treatment.

The purpose of this study was to conduct a follow-up evaluation on R.L. Casteel's Four Stage Stuttering Program at Portland State University and to examine the degree of maintained fluency in relation to entering baseline, time in program, and exit stage.

A Comparison Of The Articulatory Proficiency Between Stutterers And Nonstutterers While In A State Of Oral Sensory Deprivation, Clifford Saul Goldman

Dissertations and Theses

The purpose of this thesis was to determine if stutterers monitor speech production differently than nonstutterers while in a state of oral sensory deprivation. The specific questions asked were:

1. Does an imposed oral somesthetic feedback deficit hinder articulation proficiency more in a nonstuttering sample than in a stuttering sample?
2. If the articulation proficiency is deficient in both samples, does the nature of the errors differ between the two samples?

Listener Perception Of Fluent, Breathy, And Imprecisely Articulated Speech Of Stutterers, Diane Carol Campbell

Dissertations and Theses

Because communication involves both a sender of messages, each person could influence the other’s feelings about speaking and listening. The reactions of each member of this communication network will determine how communication will flow in the future. With an understanding of the feedback system between speakers and listeners, researchers have designed management programs which allow the speaker who stutters to develop a new pattern of speech which does not hinder his communication efforts. Fluency is the primary consideration, and normalcy of speech is second. One such program has been devised by Casteel (1974).

In Casteel’s stuttering management program a person …

Recovery From Stuttering In A Sample Of Elementary School Children, Carol Deno Kimball

Dissertations and Theses

Several studies have been undertaken to determine the incidence of recovery from stuttering; however, the results of these investigations are not reliable due to methodological limitations. For the most part, ex-post-facto recall judgements on the parts of adults or parents of young children were relied upon in gathering data for the research. It would appear that a requisite factor in determining incidence of recovery from stuttering should be the use of a formal instrument which would quantify the auditory and visual aspects of speaking behavior to determine the presence or absence of stuttering.

The primary purpose of this study was …

An Investigation Of The Relationship Between Accented Words In The Spontaneous Speech Of Stutterers And The Frequency Of Stuttering Occurrence, Cherie Richardson

All Master's Theses

This study explored the influence of word accent upon the precipitation of audible stutterings in the spontaneous speech of five adult male stutterers. The results indicated that three of the subjects stuttered with significant frequency upon accented words and two of the subjects evidenced a definite tendency to stutter on accented words. It was proposed that accented words may be a locus of stuttering in sentences and phrases of spontaneous speech in addition and perhaps relative to the four loci postulated by earlier research.

The Effect Of Labeling Disfluencies As 'Stuttering' And Contingent And Yoked "Wrong" On The Disfluencies Of Normal Speakers, Dennis Ray Staines

Dissertations and Theses

A labeling variable suggested by Wendell Johnson's "diagnosogenic" theory of the onset of stuttering was included in this study of the disfluencies of normal speaking college students in order to explore further the hypothetical relationship between normal disfluency and the onset of stuttering. A total of 60 Ss were randomly assigned to the following groups, each containing 10 Ss: I. Labeling Chastisement plus Contingent "wrong;" II. Labeling Chastisement plus Yoked (non-contingent) "wrong;" III. Labeling Chastisement - No "wrong;" IV. No Labeling Chastisement Contingent "wrong;" V. No Labeling Chastisement - Yoked "wrong;" VI. No Labeling Chastisement - No "wrong" …

The Structuring Of Procedures Utilized In An Adult Stuttering Treatment Program, Sarah Jane Prichard

Dissertations and Theses

In recent years, operant conditioning techniques have been effectively used to modify a variety of behaviors. For the most part, the modification of stuttering behavior has relied solely on the use of punishment. The shaping of "fluency” through differential reinforcement has been reported as a behavioral approach for the treatment of stuttering; however, the effectiveness of this technique in combination with other "teaching" tools, such as, modeling, instruction, and explanation has not been reported in the literature.

The purpose of this study was to construct behavioral definitions of terminology utilized in a stuttering treatment program at Portland State University to …
