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.
采用行为和受试者间的多基线设计，考察了泛化训练程序对4名慢性布罗卡失语症患者请求行为的影响。受试者被依次训练就三个主题请求信息。在每周的探测环节中评估跨主题和跨人员的泛化情况，探测环节包括在非治疗环境中与训练者和不熟悉的志愿者进行5分钟的对话互动。结果显示，与不熟悉的志愿者相比，当训练者作为对话参与者时，泛化效果最为显著。然而，在与所有对话参与者的交流中，受试者的请求次数都有所增加，达到了与在与实验探测相同条件下评估的正常对照组相当的水平。使用主观评估程序对治疗效果进行的社会效度检验显示，在健谈性、好奇心和对话成功率等参数上有显著改善。
