Masters Thesis-Open Access


A deaf, mentally-impaired youth was trained to emit intraverbal responses within the same response class to verbal stimuli which were presented in daily probe sessions (e.g., "food" evoked "apple", "bread","hot dog", etc.). Training consisted of a transfer of stimulus control procedure. If an incorrect response was made, the therapist would re-present the verbal training stimulus and immediately present a non-verbal prompt (picture) which evoked a verbal response. Since the transfer procedure was only Implemented contingent upon incorrect responding, it resulted in longer delays to trade-in for back-up reinforcers in sessions where mistakes were made. Correct responding Increased only as training occurred for each verbal stimulus* Generalization was observed to occur between training and probe sessions and across responses within the same class. In addition, token reinforcers were introduced in probe sessions to facilitate the generalization of trained behavior across therapists and settings.
