Shaping Behavior in Voice Therapy

Abstract

This study demonstrates the process of learning and shaping of behavior which occurs during a program of therapy for individuals with hyperfunctional hoarse voice quality. First a therapy program delineating the techniques and criteria to be used was written. The program was presented during 16 individual half-hour sessions over an eight-week period to three clients known to have vocal nodules. The clients' responses were charted at various points from audiotape recordings of each therapy session using a modification of the Boone-Prescott analysis system, to obtain data to demonstrate the learning processes. It was concluded that: (1) the client’s behaviors in this vocal rehabilitation program reflected a learning process; (2) facilitating techniques were used to modify or shape behavior through successive approximations to the terminal goal; (3) self-evaluation is an important factor needed to bring about successful changes in behavior; (4) analysis of client’s behaviors in relation to the learning process can aid in evaluating the effectiveness of the facilitating techniques; and (5) from such evaluation intraclient and interclient program changes are derived hopefully resulting in a greater success rate and maximum benefits from time spent in therapy.
