Once shaping has occurred, the Continuous Reinforcement (CRF) Schedule is implemented. Continuous Reinforcement means that after each desired behavior is emitted, positive reinforcement is delivered. Therefore, 100% of the desired behaviors are followed by positive reinforcement. Because a CRF Schedule requires a large supply of positive reinforcement as well as time, it is important to switch to an Intermittent or Partial Schedule of Reinforcement. With an Intermittent Schedule, fewer than 100% of the desired behaviors will be followed by positive reinforcement.
