Post-traumatic fear memories: Analysing a case study of a sexual assault
Christianson and Nilsson (1989) described a case of hysterical amnesia in a woman (called CM) who was assaulted and raped when she was out jogging. This highly traumatic event produced an almost complete retrograde amnesia up to the moment in time when she was found by a fellow jogger. When accompanied to the scene of the assault by a police oﬃcer four weeks after the assault, the victim “felt very uncomfortable at speciﬁc places, but had no recollection of the traumatic evening except that the word ‘bricks’ crossed her mind” (Christianson & Nilsson, 1989, p. 291). Later they came to a small path covered with crumbled bricks that ran parallel to the running path. When encountering this path, CM “showed an intense emotional stress, and claimed that she associated the unpleasant feelings with the pieces of bricks on the track that she was walking on. She strongly felt that something must have happened at this speciﬁc place, although she did not know for certain at this point in time that she had been raped. From the confession by the rapist a few days earlier the policeman knew, however, that this was the place where he had assaulted her and from which she had been forced out onto the small meadow where the actual rape took place” (Christianson & Nilsson, 1989, p. 291). It was only several weeks later, when she was out jogging for the ﬁrst time after the assault, at a completely diﬀerent track but one that also was covered by crushed bricks, that images of the assault started to come back to her and she eventually was able to reconstruct the whole episode.
