Tina's car was sideswiped as she was making a blind turn while leaving a parking lot. After this accident, Tina had a panic attack whenever she was near that lot, so she could not park there. Several months later, the attacks stopped, and she started parking there again. Then, one day as she was approaching the parking lot, Tina had an unexpected panic attack. This scenario exemplifies

spontaneous recovery

Explanation:

Responses to a stimulus are conditioned into individuals and some of them may remain dormant or in rest.

When such responses are reactivated it is called spontaneous recovery.

In the given scenario Tina had an accident and subsequent panic attacks every time time she came to the parking lot.

After sometime the panic attacks stopped only for them to come back again unexpectedly.

This is an example of spontaneous recovery after a dormancy period.
