Schedules of Reinforcement
Simple reinforcement-schedule responses
The four reinforcement schedules yield different response patterns. The variable-ratio schedule is unpredictable and yields high and steady response rates, with little if any pause after reinforcement (e.g., gambling). A fixed-ratio schedule is predictable and produces a high response rate, with a short pause after reinforcement (e.g., eyeglass sales). The variable-interval schedule is unpredictable and produces a moderate, steady response rate (e.g., fishing). The fixed-interval schedule yields a scallop-shaped response pattern, reflecting a significant pause after reinforcement (e.g., hourly employment).
