-Operant conditioning, sometimes also known as Skinnerian conditioning or radical behaviorism is an [[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 does only modify reflex reactions** and **operant conditioning shapes new behavior**.

 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. The rat soon learned to discriminate between the lights, and stopped or reduced pressing the lever when the "wrong" light 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. F. B. Skinner. Personality Theories.]]))
-Skinner also observed effects of different **schedules of reinforcement** (**continuous** - every day at the same time, **fixed ratio** - the reinforcement occurs every X trials, or **fixed interval** schedules - reinforcement occurs if desired behavior is showed within the time interval). One interesting observation he also made is **resistance to extinction when variable schedules is used**. Gambling presents a model of the same: reinforcement comes rarely, yet one can never be sure if it will or won't come the next time so he gives it another try.
+After accidentally running short on rat food once, Skinner also started observing effects of different **schedules of reinforcement**(([[http://webspace.ship.edu/cgboer/skinner.html|Boeree, George. F. B. Skinner. Personality Theories.]])):
-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.

+  * **fixed interval** schedules - reinforcement occurs if desired behavior is shown within the specific time interval, or
+  * **variable schedules** - number of required behavior displays in order to receive reinforcement is different every time.
+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.

+Some of his ideas Skinner incorporated in his book "Walden II", about a behavior control based utopian society. He is also remembered for claiming that if his house was on fire, he would rather save his books than his children, since his writings could make greater contributions than his genes.(([[http://webspace.ship.edu/cgboer/skinner.html|Boeree, George.

 ===== What is the practical meaning of operant conditioning? =====
-There are many examples of operant conditioning in everyday use. The act of completing homework in order to get a reward from a teacher, or **finishing projects to receive praise or promotions from the employer is a form of operant conditioning(([[http://psychology.about.com/od/behavioralpsychology/a/introopcond.htm|Cherry, K. Introduction to Operant Conditioning. About.com Psychology.]])). In these examples, the increased probability of certain behavior is the result of possibility of **rewards**.

 Oppositely, operant conditioning can also be used to **decrease** probability of certain **behavior by** use of **punishment** (//averse stimulus//). For example, children in classroom may be told they will have to sit in the back of the classroom if they talk out of turn(([[http://psychology.about.com/od/behavioralpsychology/a/introopcond.htm|Cherry, K. Introduction to Operant Conditioning. About.com Psychology.]])). The possibility of punishment may decrease the probability of unwanted behaviors.
