Description
  Extinction (Ext):  if a behaviour that was previously reinforced stops being reinforced,  the behaviour will stop occurring. Example: you turn the handle to open the emergency  door(response)▯ the door does not open(consequences)▯ you are less likely to use this door  in future. Other research applied to both humans (child trantrum), pigeon and rat ( not  given food when hit the lever) etc. •  Main points of Extinction:   1. A behaviour that has been previously reinforced 2. no longer results in the reinforcing consequence 3. And therefore, the behavior STOPS occurring in the future(Ext) • Something to watch for:  Correct ▯ you extinguished the behavior and NOT correct to say  you extincted behavior. Correct ▯ you put a behavior on extinction rather than a person.  Correct▯behavior is extinguished rather than extinct.   Extinction Burst:  • 1) Behaviour may briefly increase in frequency, duration, or intensity after the  reinforcement is eliminated e.g., child swears: parents ignore it; swearing increases  before declining to 0. But this is a natural process ( not necessarily a conscious process  either) • Extinction Burst: after a period of extinction, behaviour may reappear, despite the lack of  reinforcement.  2) Interesting to note that often we see a novel behavior: a behavior that  never occurred before but occurs this time when there is not reinforcement (i.e. child  swearing increases but also this time he punches the doors). 3) Sometime might be  emotional responses (i.e. you don’t get you food so your get angry and curse) or  aggression might occurs.   Spontaneous recovery:  • After a period of extinction, behaviour may reappear,
