Applied Behavior Analysis is a science and, therefore, involves progressive approaches and outcomes. In this panel discussion we argue that the spirit and the method of science should be maintained in order to avoid reductionist procedures, stifled innovation, and rote, unresponsive protocols that become increasingly removed from meaningful progress for individuals diagnosed with autism spectrum disorder. We describe this approach as progressive. In a progressive ABA approach, the therapist employs a structured yet flexible process, which is contingent upon and responsive to child progress. We will describe progressive ABA and provide rationales for both the substance and intent of ABA as a progressive scientific method for improving conditions of social relevance for individuals with ASD. The chairperson will pose a variety of questions to the other panel members to engender a discussion about how, as a field, we can move toward a more progressive approach and the potential obstacles behavior analysts might face along the way. Finally, we will take questions from the audience members to help facilitate the discussion. The goal of the panel is to help the audience to identify what constitutes progressive ABA and how we as behavior analysts can reach these high standards.
