Clinicians are particularly challenged by the development of interventions for behavior maintained by automatic reinforcement because reinforcers that maintain the responses often cannot be directly observed or manipulated. Researchers have conducted either preference assessments or competing items assessments when developing effective treatments for behavior maintained by automatic reinforcement. However, interventions based on these assessments have not been directly compared. The current study evaluated procedures to make such a comparison. High-competition items resulted in greater reductions in vocal stereotypy than did high-preference items for a preschool boy with autism.
临床医生在开发由自动强化维持的行为干预措施时面临特别的挑战，因为维持反应的强化物通常无法直接观察或操纵。在为自动强化维持的行为开发有效治疗方法时，研究人员已经进行了偏好评估或竞争项目评估。然而，基于这些评估的干预措施尚未直接进行比较。本研究评估了进行这种比较的程序。对于一个患有自闭症的学龄前男孩，高竞争项目导致的发声刻板行为减少量大于高偏好项目。
