ScheduleSim is an interactive tool that lets you explore the foundations of behavior analysis by directly experiencing how basic reinforcement schedules work. With a single click, you can respond on a virtual key and see how reinforcers are delivered across fixed and variable schedules.

What makes ScheduleSim especially powerful is the live cumulative record display. As you respond, the graph is generated in real time, just like the classic records used in experimental analysis of behavior. You’ll be able to see how patterns of responding emerge under different schedules and how to interpret the unique slopes, pauses, and resets that characterize each one.

Whether you’re a student learning the fundamentals, a teacher looking for a classroom demo, or simply curious about the science of behavior, this free tool offers a hands-on way to visualize reinforcement principles and cumulative records as they happen.
