Spontaneous Recovery

Modified: 2020-03-27


One extinction episode is usually not enough to undo completely a conditioned response. So, when an animal is returned to the original conditioning situation and allowed to make the conditioned response, it will. In order to obtain complete extinction, many extinction trials will be required. Think of how many trials were required for the original conditioning. It only makes sense that a similar number of trials will be required for complete extinction.

Think about someone trying to quit drinking alcohol. When they return to the same situations where they used to drink, they must battle spontaneous recovery. That is why programs like Alcoholics Anonymous try to prevent their members from returning to their old haunts. Another good example is when a recently divorced couple visit each other. They may, through spontaneous recovery, engage in an old conditioned response (e.g., lovemaking), much to the chagrin of their new partners.
