Document Summary
Extinction: is a basic principle of behaviour in which a behaviour that has previously been reinforced for a period of time was no longer reinforced and therefore the behaviour stops occurring in the future. Extinction burst-when behaviour is no longer reinforced, three things might happen: the behaviour may briefly increase in frequency, duration and intensity, novel behaviours may occur, emotional responses and aggressive behaviour may occur. Spontaneous recovery: is the natural tendency for the behaviour to occur again in situations that are similar to those in which it occurred and was reinforced before extinction. E. g amanda may cry at night long after extinction and if she gets no attention, she will eventually stop crying. However, if her parents come and give her attention, then her behaviour is reinforced and the effect of extinction will be lost. The positive reinforce is no longer delivered after the behaviour. The negative stimulus is no longer removed after the behaviour.
