A Study of the Behavioral Components of Stuttered Speech. Final Report.
Prins, David T.; Lohr, Frances E.
Selected visible and audible features of stuttered speech were studied to determine whether these phenomena suggested a basis for differentiating among stutterers. Forty-six visible and audible phenomena of stuttering were examined in 23 stutterers, using a frame-by-frame analysis of sound motion picture film. Significant inter-subject differences were found in 11 of these variables which included the following: adaptation, number of film frames in the moment of stuttering, simultaneous suspension of jaw and lip activity, eyelid closure, eyelid movement, total visible tension, number of anatomical areas involved in the moment, and several indices of unilateral facial deviations. A factor analysis of the correlations among audible and visible variables revealed 10 factors which accounted for 83% of the variance. Six of these factors were similar to stuttering dimensions which previously had been implied or hypothesized, but had not been empirically derived; overall stuttering severity, type of audible dysfluency, adaptation, type of unilateral deviation, tension, and stuttering differences between spontaneous speech and reading. Applications are presented of the results of this study to the differentiation and classification of stutterers. (Author/RD)
