Abstract Details

1973, Doctor of Philosophy (Ph.D.), Bowling Green State University, Communication Disorders.
This study attempted to determine if the frequency of stuttering during adaptation is differentially influenced by selected phonemic and articulatory feature cues embedded in a reading task. Furthermore, an attempt was made to determine if the relationship between molar and molecular units of stuttering is also influenced by these cues. Eight subjects were selected based on their responses to a questionnaire in which they indicated that they experienced unusual difficulty with certain phonemes in the reading task. The phonemes represented specific cues which, through experimental design, were isolated from other variables known to influence stuttering. Each subject was video taped while reading the experimental sentences fifteen times or for one hour, whichever came first. Molar units of stuttering and their molecular components were tabulated as they occurred on each of the specific phonemic cues. A single-subject design was employed. The frequency of molar and molecular units of stuttering was: (1) plotted separately for each of the four different phonemes; (2) plotted collectively for all of the phonemes combined; (3) collapsed across, and plotted along, anterior and posterior phonemes; (4) collapsed across, and plotted along voiced and voiceless phonemes. The subjects in this study represented a subgroup of the general stuttering population identified on the basis of their past experience with certain sounds. Conclusions, therefore, are generalizable only to stutterers in the general population who meet the same criteria. Three subjects exhibited cycles of responding that resemble those produced by lower organisms during the experimental extinction of operantly learned behavior. For most subjects the frequency of stuttering and the ratio between molar and molecular units of stuttering during adaptation were differentially influenced by the presence of phonemic and/or articulatory feature cues. Certain phonemic cues and/or their properties may represent a special class of discriminitive stimuli that exert differential degrees of stimulus control over stuttering behavior.
