Elements of Classical conditioning Extinction • occurs in classical conditioning when a CR no longer occurs when the CS is presented • E.g. The Dog stopped salivating after a while when Pavlov rang bell and did not present the food.
CC: Spontaneous Recovery • Reappearance of a C.R following a rest period (i.e. when no C.S is presented) • But note: Spontaneous recovery occurred after the CR has been extinguished (and a corresponding time gap) E.g.ForPavlov’s experiment – • CS extinguished (i.e. bell – no food (UCS) – No response (CR) • After a time gap • The CS (bell) is presented again (without the UCS - food) & the CR results (salivation occurs) • The CR has spontaneously recovered
