Teacher attitudes toward stuttering

Attitudes of 100 elementary school teachers toward stuttering were studied using the Teacher Attitudes Toward Stuttering (TATS) Inventory. Teacher attitudes, as indicated by TATS Inventory scores, were compared with teacher knowledge of stuttering, age of teacher, number of years teaching experience, educational level, and whether the teacher had personal experience with a stutterer. Results indicated that significant positive correlations existed between teacher attitudes toward and knowledge of stuttering. Significant negative correlations were demonstrated between teacher attitudes/knowledge of stuttering and the presence of a stuttering child in the classroom. The applicability of the TATS Inventory as a clinical instrument in its current form and the research needed to enhance its flexibility are discussed.     

Clinician attitudes toward stuttering in the United States and Great Britain: A cross-cultural study

The attitudes toward stutterers and stuttering of 702 speech-language clinicians in the United States and Great Britain were studied. Three hundred seventy-one clinicians from six states in the U.S. and 331 clinicians from England and Wales completed the Clinician Attitudes Toward Stuttering (CATS) Inventory. Results of the study were analyzed in terms of differences and similarities in attitudes between the two groups with respect to the etiology of stuttering, early intervention, the effectiveness of stuttering therapies, various therapy techniques, stutterers and their personality, parents of stutterers, clinicians, and reactions of others to stutterers.     

The effect of punishment and reinforcement procedures on a stutterer's factor II avoidance response

The purpose of this clinical experiment was to investigate the manipulability of a Factor II avoidance response (arm movement). The substantive hypothesis under test was that its suppression would be enhanced by repeated punishment sessions. During the first of nine therapy sessions response-contingent negative stimulation was not delivered. In the next five, after a base-rate period, “wrong” was made consequent upon the target response. In each of these sessions the suppression of arm movement was apparent. However, the magnitude of the suppression decreased from session to session. Evidently, the continued use of punishment did not enhance suppression. Because of this finding procedural changes were introduced in the next three therapy sessions. Verbal praise was added as a consequence of increasingly stringent omission criteria and three consecutive units of praise led to time-out from the reportedly fatiguing task of continuous speech. A marked reduction and then complete extinction resulted. Moreover, learning was evidenced since the frequency of arm movement lessened in the base-rate period of each session.     

The effect of punishment on a factor I stuttering behavior

On each of five days the subject of this experiment read aloud different material during an 18-min A₁ (base rate), B (experimental), and A₂ (extinction) period. No stimulation was delivered during the first three days. On the fourth day, the nonsense word “norg” was presented noncontingently during the experimental period. There was no statistically significant difference between the A₁ and B periods on any of these four days. On day five, “wrong” was made contingent on Factor I prolongations during the experimental period. As a result, there was a statistically significant increase in their frequency. When the response consequence was removed in the A₂ priod, there was a reliable reduction in prolongations and the frequency closely approximated that found in the A₁ period. These data suggest that response-contingent negative stimulation is contraindicated as a clinical tactic for use with Factor I prolongations. It not only failed to suppress them, it increased their frequency.     

Are mothers of stutterers different? An investigation of social-communicative integration

Many speech-language pathologists assume that parent-child communicative interactions are critical precipitating or maintaining factors in the onset and development of stuttering. Although parents are frequently counseled to alter their attitudes or behaviors, no studies have pinpointed specific parental behaviors as increasing children's disfluency. The purpose of this study was to analyze differences between 12 mothers of stutterers and 12 mothers of nonstutterers in their social-communicative interactions with their own child, an unfamiliar stutterer, and an unfamiliar nonstutterer. Ten minutes of free-play interaction between each mother and child were video recorded from behind a one-way mirror. Results indicate that the two groups of mothers differed significantly only in their use of routine statements. Other findings indicate that stuttering children used significantly more positive and imperative statements than nonstuttering children. All children asked significantly more questions of their own mothers than of unfamiliar mothers.     

Speech timing skills of normally fluent and stuttering children and adults

This study was designed to explore the speech timing skills of normally fluent and stuttering children and adults producing two sentences, ten consecutive times at basal and modified speaking rates. Spectrographic displays of subjects' utterances in both conditions were made in order to obtain consonant, vowel, pause, and utterance duration measures. Results showed that (1) the two groups of children produced speech durational values similar to those of the two adult groups and (3) there were no consistent between- and within-group differences in the basal and modified rate conditions. Findings are discussed in terms of methodological and sampling differences that exist between the present study and past research on stutterers' speech production abilities.     

Fluency breaks in older speakers: Implications for a model of stuttering throughout the life cycle

In order to test a model describing the occurence of fluency breaks throughout the life cycle, spontaneous speech samples of 40 nonstutterers and 4 stutterers above the age of 50 were perceptually analyzed. Fluency breaks were classified into categories of formulative or motoric breaks. The results supported research, noting an increase in formulative fluency breaks (especially fillers and interjections) for older speakers. There was, however, a significant decrease in the occurence of formulative fluency breaks during the final years of late adulthood. No change was found in the occurence of motoric fluency breaks in the nonstuttering speakers. Stuttering speakers had significantly less formulative breaks and significantly more motoric breaks than nonstuttering speakers.     

“Snowball” and other control groups

In the Spring of 1973, the Office of Research and Development of the Appalachian Center, West Virginia University, began an evaluation of the University's mining extension program. Since all interested miners are allowed to enroll in the course, the only feasible way to obtain a control group was to use the “snowball process.” This paper examines how well the snowball process did in producing a control group which matched the trainees. While the trainees and controls seemed well matched on many demographic characteristics they differed on several variables, particularly attitudes.     

The problem of relapse in stuttering: Some thoughts on what might cause it and how to deal with it

Bloodstein recently wrote that “the most vital part of science is not accurate measurement or the insistence on empiricism. It is an attitude of inquiry into the how and why of things” [Bloodstein, O. Foreword. In: Maintenance of Fluency (E. Boberg ed.). New York: Elsevier, 1981, p. vii]. In the paper below, I present some unsubstantiated and no doubt controversial thoughts on the how and why of relapse in stuttering. The overall thrust of these thoughts is that stutterers have different propensities to stutter because of the inherent variability in their speech production systems. For this reason, for therapy to have long-range success, stutterers must learn to accept and deal with the inherent variability in their speech production mechanisms.     

A case of adult onset of stuttering

A 36-yr-old adult male was treated for stuttering after a “sudden onset” of disfluency according to the client, 3 yr before. The treatment method and results are described and the “awareness” feature of stuttering onset is discussed.     

Word frequency and children's stuttering: The relationship to sentence structure

This study investigated the relationship between word-frequency level and stuttering within the context of four slected sentence types. Fifteen stuttering children, aged 8–12, read 48 sentences of four different transformational types, and three word-frequency levels 12 simple active-affirmative-declarative (SAAD), 12 negative, 12 passive and 12 negative-passive. All sentences were identical in terms of underlying swings and variations of the SAAD sentences. Results agreed with Ronson's study with adults (1976) in that when the group rating was severe and the sentence type was negative, stuttering increased significantly as word-frequency level decreased. It appears that children's stuttering in relationship to word-frequency level is a different response that is subject to variables of sentence type and the severity rating of stuttering.     

An awareness approach to the covert symptoms of stuttering

Speech-language clinicians working with the confirmed stuttering client are often faced with the clinical management of the covert symptoms of stuttering in addition to the more observable and measurable overt symptoms. The authors report the successful use of awareness techniques to exaggerate the subjective experience of these covert symptoms and encourage the use of these techniques as an adjunct to the counseling and desensitization procedures traditionally employed. A transcribed clinical management session in which several awareness techniques are used to aid the client in an introspective examination of “anticipation of stuttering,” is analyzed in order to reach some specific recommendations for using awareness techniques in the clinical management of the covert symptoms of stuttering.
