The Role of Expectations in the Development of Intrusive Memories: An Experimental Approach Using the Trauma Film Paradigm  May 13, 2019

The study aims to examine the influence of different expectations on the development of intrusive memories by using a well-established experimental paradigm - the trauma film paradigm. In healthy volunteers, intrusion-like symptoms are to be induced with an analogue stressor, i.e., aversive film clip footage (trauma film). After viewing this so-called trauma film, the expectations of intrusions during the following week are manipulated by assigning participants randomly to three different groups. In the first group, negative expectations are induced (experimental group 1), the second group is exposed to positive expectations (experimental group 2) and a third group does not face any kind of manipulation of their expectations (control group). Participants are asked to report occurring intrusions in a diary during the following week and are invited to a subsequent cued laboratory inquiry at follow-up.
