| - | Operant conditioning, sometimes also known as //Skinnerian conditioning// or //radical behaviorism// is a [[learning_paradigms:behaviorism|behaviorist]] learning approach similar to [[clasicall_conditioning|classical conditioning]], mostly influenced by early theoretical and experimental works of American psychologist [[http://www.bfskinner.org/BFSkinner/AboutSkinner.html|Burrhus Frederic Skinner]] from the 1950s. Main difference between those two theories is that **classical** conditioning **modifies only reflex reactions** and **operant** conditioning **shapes new behavior**. | + | Operant conditioning, sometimes also known as //Skinnerian conditioning// or //radical behaviorism// is a [[learning_paradigms:behaviorism|behaviorist]] learning approach similar to [[clasicall_conditioning|classical conditioning]], mostly influenced by early theoretical and experimental works of American psychologist [[http://www.bfskinner.org/bfskinner/AboutSkinner.html|Burrhus Frederic Skinner]] from the 1950s.

The rat soon learned to discriminate between the lights, and stopped or reduced pressing the lever when the "wrong" light was on. | In another experiment, two lights (red and green) were introduced into the box and the rat would only get the food if one of them was on.

| - | Unlike Pavlovian conditioning, where an existing behavior (salivating for food) is shaped by associating it with a new stimulus (sound of a bell), operant conditioning is the **rewarding of an act that approaches a new desired behavior**, but can also be the opposite: **punishing undesirable behavior**. | + | Unlike Pavlovian conditioning, where an existing behavior (salivating for food) is shaped by associating it with a new stimulus (sound of a bell), operant conditioning is the **rewarding of an act that approaches a new desired behavior**, but can also be the opposite: **punishing undesirable behavior** (negative reinforcement).(([[http://webspace.ship.edu/cgboer/skinner.html|Boeree, George.

| An interesting observation he made was that if fixed interval is used, rats managed to find a "rhythm" in displaying of behavior, which was never the case in variable schedules. Variable schedules, surprisingly, have also shown to be very resistant to extinction. The gambling addiction offers another example for this: although reinforcement comes rarely, one can never be sure if it will or won't come the next time so he gives another try. | An interesting observation he made was that if fixed interval is used, rats managed to find a "rhythm" in displaying of behavior, which was never the case in variable schedules.

| - | Operant conditioning can also be used to **shape more complex behaviors** by starting from an idea similar to the intended behavior and after it is learned **slowly shaping it until it becomes exactly what was desired**. An example of this is how Skinner and his students managed to teach pigeons to bowl. | + | Operant conditioning can also be used to **shape more complex behaviors** by starting from an idea similar to the intended behavior and after it is learned **slowly shaping it until it becomes exactly what was desired**.
