Fear is a universal experience and fuels our response to cope with threat. Persistent fear, after the threat is no longer present, is a central symptom seen in a number of clinical disorders. Current treatment focuses exclusively on trying to reduce the fear response (fear extinction), rather than target the underlying mechanism: inhibitory learning. Using a newly developed paradigm, we will target inhibitory learning using intentional memory suppression during extinction. We will test whether intentional memory suppression can stop the retrieval of fear memories and, as a result be used to boost fear amnesia, the forgetting of the fear.
