A Hearing Assessment Using Operant Audiological Testing With A Severely Retarded Deaf-Blind Child, Patricia Timpson

Masters Theses

This study assessed the feasibility of teaching a 7-year-old severely retarded, hearing and vision impaired girl to respond consistently to a pure tone stimulus using operant audiometric techniques. The experimenter first shaped a head turn response using the opportunity to rock on a rocking horse as reinforcement. Following response shaping, the experimenter used a bone conduction transducer (BCT) as a tactile stimulus in training the subject to turn her head to the left in a similar fashion to a 500 Hz, 65 dB tone/vibration. After 15 days of transfer training, designed to bring the left head turn response under control …
