Rezonans Ses Ediniminde Klinisyen Geri Bildirim Özelliklerinin Etkisinin İncelenmesi

Abstract

There are clinical researches which aim to adapt motor learning principles to voice therapy and which examine individual differences that underlie of behavioral changes and skill acquisition. While there are many studies at the ‘practice’ phase regarding the characteristics of clinician feedback for motor learning principles in the field of voice therapy, there are few studies available in the ‘prepractice’ phase. In this thesis study, by keeping the prepractice phase components motivation, verbal information and modeling steady; resonant voice training was applied by 2 Speech and Language Therapists to 6 different groups (n=90) consisting of women with healthy voices between the ages of 18-35, in which feedback characteristics changed. These 6 groups; consists of groups that do not receive any feedback, receive knowledge of result feedback and receive knowledge of performance feedback (4 subgroups). Auditory-perceptual and acoustic assessments were made before and after the training. Auditory-perceptual assessment was made by 3 experts experienced in the field by grading the quality of the resonant voice, and a statistically significant difference was found between the groups when the participant groups were compared (p<.05). According to the results of multiple comparison analysis, a statistically significant difference was found between the group that did not receive feedback and the kinesthetic + visual + auditory feedback group after the Bonferronni correction (p<.05). According to the findings of the analyzes of acoustic assessment, there was no significant difference between the groups in terms of the intensity and the Cepstral Peak Prominence, but an increase in the repetitions at the end of the training was detected in the feedback-given groups. The findings of the study indicate that it is beneficial to give feedback by using different sensory modalities in the prepractice phase and to use knowledge of result feedback in the acquisition of the resonant voice.
