Document Summary
It is a process tht weakens operant behavior. A behavior tht had been reinforced for a period of time was no longer reinforced and behavior stopped occurring. Extinction occurs when a behavior tht has been previously reinforced, no longer results in the reinforcing consequences, and therefore, the behavior stops occurring in the future. Skinner and then joined by ferster demonstrated the principle of extinction with lab animals. When the pigeon in the exprmntl chamber no longer recvd food as a reinforce for pecking the key, the pigeon"s key-pecking behavior stopped. When the lab rat no longer rcvd food pellets for pressing the lever, the lever-pressing behavior decreased and eventually stopped. U don"t extinct a person but rather extinguish a behavior. U could put a behavior on extinction not a person. In the extinction process is tht once behavior is no longer reinforced, it increases briefly in frequency, duration or intensity before it decreases and ultimately stops is called extinction burst.
