This study used a combined design to evaluate the effects of nonvocal demands on vocal stereotypy in novel locations by implementing a concurrent multiple baseline design across settings, replicated across all participants. Results indicated that both the traditional and modified response interruption and redirection (RIRD) intervention were effective at reducing occurrences of vocal stereotypic behaviors for all four participants. The traditional RIRD intervention initially resulted in a larger decrease of these behaviors than the modified RIRD intervention; however, by the end of the study, the effects of both interventions on occurrences of vocal stereotypic behaviors were similar. Additionally, the effects of the RIRD intervention on occurrences of vocal stereotypic behavior met mastery criteria and generalized across settings for all four participants. The RIRD intervention generalized to the additional setting in less time than it took for the RIRD intervention to be effective in the first setting for all four participants.

具有声音刻板印象的响应中断和重定向过程的概括

本研究采用组合设计，通过跨设置实施并发多基线设计，在所有参与者中复制，评估非声音需求对新位置声音刻板印象的影响。结果表明，传统和改进的响应中断和重定向 (RIRD) 干预都有效地减少了所有四名参与者的声音刻板行为的发生。与改良的 RIRD 干预相比，传统的 RIRD 干预最初导致这些行为的减少幅度更大；然而，在研究结束时，两种干预措施对声音刻板行为发生的影响是相似的。此外，RIRD 干预对声音刻板行为发生的影响符合掌握标准，并在所有四名参与者的环境中推广。RIRD 干预推广到附加环境所需的时间比 RIRD 干预在第一个环境中对所有四名参与者都有效所需的时间短。
