ASudden appearance of a brand new response never seen before
BReappearance of an extinguished response after a period of rest
CReplacement of one conditioned response by an entirely different one
DGeneralisation of a conditioned response to all neighbouring stimuli
Answer & Solution
Correct answer: B. Reappearance of an extinguished response after a period of rest
1. After extinction, the conditioned response appears to be gone.
2. However if a period of time elapses and the CS is then presented again, the response reappears.
3. The chapter names this reappearance spontaneous recovery.
4. Amount of recovery depends on how much time has lapsed since the extinction session.
5. Hence spontaneous recovery is reappearance of an extinguished response after a rest interval.
