This investigation explored voice use and perception of use in singers as compared with non-singers at the university. Students recorded the amount and type of their voice use for forty-eight hours. They made judgments about their use and whether a voice disturbance was present. Each student was taped, and tapes were judged for disturbances. It was hypothesized that singers would have greater voice use and awareness than non-singers and experienced singers would have greater voice use and awareness than less experienced singers. Singers used their voices more than non-singers, but there were no differences in awareness. No differences between singer groups were noted. There was a high incidence of voice disturbances in all groups. Suggestions for future research were made.
Responses of six severely language delayed (SLD) children were obtained on three measures of central auditory processing and one measure of language proficiency. The results of these measures were compared to the results obtained from six normal-hearing children, matched in age and Performance IQ on the WISC-R. The 12 children were tested with the Pitch Pattern Sequence Test (PPST), the Dichotic Digit Tests (DDT), and the Pediatric Speech Intelligibility Test (PSI). Differences in the central auditory abilities as well as the history of each child were presented in .a case study format. The results of the history information demonstrated no unusual problems among these 12 subjects. Ten out of 12 subjects demonstrated abnormal results on at least one measure of the central auditory battery.
Responses of 122 children were obtained on two measures of central auditory processing to establish normative data. Children aged 6.5 through 12.5 years were tested for humming and tapping responses to the Pitch Pattern Sequence Test (PPST) and the two- and four-digit Dichotic Digit Tests (DDT). Children between ages 6.5 and 9.5 years showed progressively better scores on the tapping response of the PPST and on the four-digit DDT. Children above 9.5 years of age demonstrated adult-like responses on both tests. No differences were demonstrated in performance of children aged 6.5 through 12.5 years on the two-digit DDT or on the humming response of the PPST.
