| Abstract: The terms Motivating Operation and Discriminative Stimulus are widespread and thought to be generally well understood in the field of ABA. However, there are significant issues with Interobserver Agreement among Behavior Analysts when attempting to discriminate between these stimuli in realistic situations. Jack Michael made a major contribution to the science of ABA with his development of the MO concept. However, further refinement of the concept, as well as the published definition of the discrimination stimulus need to be explored. This talk explores IOA in textual vignettes and video stimuli, uses Equivalence Based Instruction to teach revised definitions of these terms and evaluates whether IOA improves. It also evaluates the utility of Moodle as a platform to deliver equivalence based instruction to large groups without a proctor. Discussion and evaluation of the applied utility of current definitions for stimulus control are discussed as well. |
