Psychologists are at odds over the idea that people can forget traumatic events then “recover” intact memories of the trauma years later. On one side are clinicians, who observe that painful memories can be repressed, banished from a trauma survivor’s consciousness until they’re “recovered” with the help of certain psychotherapeutic techniques in adulthood. Memory researchers, on the other hand, say that people don’t repress traumatic events.
