CHAPTER 5 EXTINCTION Defining extinction a behaviour that had been reinforced for a period of time was no longer reinforced and therefore the behaviour stopped occurring Extinction occurs when 1 A behaviour that has been previously reinforced 2 No longer results in the reinforcing consequences 3 And therefore the behaviour stops occurring in the future when a behaviour stops occurring bc it is no longer reinforced we say that the behaviour has undergone extinctionExtinction burst one characteristic of the extinction process is that once the behaviour is no longer reinforced it often increases briefly in frequency duration or intensity before it decreases and ultimately stops extinction burst Eg your remote is dead You push the power button and it doesnt turn on the tv You push longer and harder and then you quit trying but not until you tried pushing it longer and harder this is the extinction burst another characteristic of extinction burst is that novel behaviours behaviours that dont usually occur may occur for a brief period when a behaviour is no longer reinforcedsometimes the novel behaviours during extinction bursts may include emotional responsesEg get angry and curse or kick or hit the object extinction burst serves a valuable purpose bc sometimes the novel behaviours may be reinforced Eg if you push the remote REALLY hard it could turn the tv on and it could be that the button was just stuck extinction burst is not necessarily a conscious process it may just be a natural characteristic of an extinction situationSpontaneous recover
