Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.
Once a behavior is learned, trainers often switch to partial reinforcement, where rewards are given intermittently rather than every time. Partial reinforcement can be classified into four types: fixed interval, variable interval, fixed ratio, and variable ratio.
Understanding these reinforcement schedules helps in effectively shaping and maintaining desired behaviors in both educational and training settings.
