Facilitating generalized requesting behavior in Broca's aphasia: an experimental analysis of a generalization training procedure.
The effects of a generalization training procedure on requesting by 4 subjects with chronic Broca's aphasia were examined using a multiple baseline design across behaviors and subjects. Subjects were trained to request information on three topics sequentially. Generalization across topics and persons was assessed in weekly probe sessions consisting of 5-min conversational interactions with trainers and unfamiliar volunteers in a nontreatment setting. Results revealed generalization effects were greatest when trainers, as opposed to unfamiliar volunteers, served as conversational participants. Nevertheless, subjects' requests increased with all conversational participants to a level comparable to a normal comparison group assessed under conditions identical to the experimental probes. Social validation of treatment effects using a subjective evaluation procedure revealed significant improvement on the parameters of talkativeness, inquisitiveness, and conversational success.
