VCE U4 Psychology - Extinction and spontaneous recovery

  1. 1. Elements of Classical conditioningExtinction• 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.
  2. 2. 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.For Pavlov’s experiment –1. CS extinguished (i.e. bell – no food (UCS) – No response (CR)2. After a time gap3. The CS (bell) is presented again (without the UCS - food) & the CR results (salivation occurs)4. The CR has spontaneously recovered
  3. 3. Extinction & Spontaneous Recovery
