Ali frequently engages in humming during academic instruction. His behavior analyst sets a reinforcement criterion based on Ali’s rate of humming during the previous week’s academic periods. The behavior analyst permits Ali to leave academic instruction 15 minutes early if he hums fewer times than he did, on average, the previous week. The analyst adjusts the reinforcement criterion weekly until rates of humming are near zero. Which differential reinforcement schedule is exemplified in this scenario?
