B.F. Skinner on Schedules of Reinforcement

This one-minute video discusses schedules of reinforcement in B.F. Skinner‘s experiments. Reinforcement is delivered to different animals on a schedule that states the contingencies on which reinforcement depends. Interval schedule is contingent upon the passage of time. Ratio schedule is contingent upon the number of responses emitted. A variable ratio schedule (contingent upon an unpredictable number of responses) produces a very high and stable rate of responding.
