Abstract
Children with autism spectrum disorder (ASD) usually show little interest in academic activities and may display disruptive
behavior when presented with assignments. Research indicates that incorporating motivational variables during interven tions results in improvements in behavior and academic performance. However, the impact of such motivational variables
varies between children. In this paper, we aim to address the problem of selecting the right motivator for children with
ASD using reinforcement learning by adapting to the most infuential factors impacting the efectiveness of the contingent
motivator used. We model the task of selecting a motivator as a Markov decision process problem. The states, actions and
rewards design consider the factors that impact the efectiveness of a motivator based on applied behavior analysis as well
as learners’ individual preferences. We use a Q-learning algorithm to solve the modeled problem. Our proposed solution
is then implemented as a mobile application developed for special education plans coordination. To evaluate the motivator
selection feature, we conduct a study involving a group of teachers and therapists and assess how the added feature aids
the participants in their decision-making process of selecting a motivator. Preliminary results indicated that the motivator
selection feature improved the usability of the mobile app. Analysis of the algorithm performance showed promising results
and indicated improvement of the recommendations over time.
