Abstract

Flashback, related to the traumatic event, is a prominent symptom of posttraumatic stress disorder (PTSD). The dual representation theory (DRT) of PTSD emphasizes that the weakened contextual representation (C-rep), the enhanced sensory representation (S-rep) and the loss of connection between C-rep and S-rep play an important role in the formation and retrieval of flashback. DRT proposes that cognitive intervention tasks which inhibit S-rep or enhance C-rep can reduce flashbacks. And many studies have proved this theoretical hypothesis. In the future, simulation intervention studies should continue to strengthen, some clinical application studies should also be appropriately carried out. Besides, future researchers should innovate the ideas of intervention, focus on designing new cognitive intervention tasks.
