Abstract

Trauma-related flashback is one of the typical symptoms of patients suffered from posttraumatic stress disorder (PTSD), which intrudes into the body and mind of patients uncontrobaly and repeatedly. Psychodynamic theories of mechanisms of the formation and involuntary repetition of trauma-related flashback establish a foundation for most cognitive theories of PTSD. Cognitive behavioral theories of PTSD, from the initial use of behavioristic principles (e.g., conditioning, alternative learning, generalization, etc.) to explain fear conditioning to the emphasis on the roles of cognitive and behavioral factors (e.g., cognitive model or schema, completion tendency, associative network, data-driven processing, analogue representation, etc.) in the representation and retrieval of traumatic information, present a trend of multirepresentational theorizing. Inherited from the theories proposed by Pierre Janet in the early years of the 20th century and based on the integration of existing cognitive behavioral theories of PTSD, theories of the multiple memory system bring new viewpoints on the representation and retrieval of traumatic information in memory. In the last twenty years, several recent theories have received some empirical evidences both in theoretical and applicational. The clinical and nonclinical implications of the psychological explanations of trauma-related flashback, the ideas of further explorations in the theories of PTSD and the directions of future researches of the prevention and treatment of PTSD are presented.
