Answer:
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.
