It has been determined that trauma alters memory, this mostly effects the episodic memories that individual has. When thinking about this statement it made me think about how abusers and the abused remember things so differently. This made me want to look further into the effects of trauma on memory. I found a study that focuses on Sexual trauma effecting episodic memory.
“Rape survivors with post-traumatic stress disorder (PTSD) show poorer episodic memory than rape survivors without PTSD, and poorer memory than non-victims.” (Jenkins, Langlais, Delis, & Cohen, 1998). This was determined with normal neutral memory tests. It was shown in a meta analysis conducted that individuals that have PTSD show verbal memory deficits. This of course makes sense when thinking about emotional stimuli, we are more likely to remember the emotional events versus the non-emotional events.
When interviewing individuals about the sexual trauma they experienced and then once again five years later, they discovered that the memory of the SA is always more consistent than any positive memories. The study that I am specifically writing about though focuses on examining episodic memories in relation to non-autobiographical content.
Participants were recruited through advertisements in Quebec. The sample size ended up being 84 volunteers, 27 of which were SA survivors. 7 of these individuals meat the criteria on the CAPS (Jenkins, Langlais, Delis, & Cohen, 1998). The researchers implemented a couple ways of collecting their data such as; A memory test that was based on the Wechsler Memory Scale 3rd Edition and questionnaires. They started with an initial interview, then did clinical interviews (questionnaires), and finished their study up with the memory task. Each individual listened to three recorded stories read by a female narrator, once complete they were asked to dictate every detail that they remembered from the stories.
The interviews proved that on average SA victims experience and display more signs of PTSD. The memory task showed that the SA survivors recalled less information from the neutral story that was read for them, they also recalled significantly less information when the emotional story was read. The recalled information for the more traumatic story did not differ much from the control group to the survivor group. After conducting ANOVA they determined that the survivors that met the diagnostic criterion on the CAPS showed no difference from the individuals that did not when in regards to; neutral, generally emotional, and trauma-related items (Jenkins, Langlais, Delis, & Cohen, 1998).
I found this determination especially interesting because I would think that the ones that had more diagnostic criteria would respond more to the generally emotional story. This is part of a small group of studies that have been created for this topic, I hope they continue to work on this, and maybe I could contribute to the research in the future.
