My article is entitled: “Voluntary switching between identities in dissociative identity disorder: a functional MRI case study” and written by RL Savoy, BB Frederick, AS Keurogilan and PC Wolk. The article is about Dissociative Identity Disorder (DID), and it used to be called Multiple Personality Disorder (MPD). DID is when a person has multiple personalities, or alterations, in one body. Alters are their own person, with their own characteristics, age and even gender. In this article, one participant had an adult, child, and baby personality. This article presents research on what happens in the brain when a person transitions to another alter. Wolk, one of the authors, has worked with a patient, RV, for over 20 years (Savoy, RL et al, 2012, p. 1). RV, derived from the nickname Research Volunteer, has DID and she is actually able to switch between edits voluntarily. She had two other alters, a little girl aged 4 to 6 and a non-verbal baby (Savoy, RL, et al, 2012, p. 2). To conduct this research and study her brain during changes, she was placed in an fMRI. They did some preliminary trials and tests to make sure she could switch in an environment like fMRI and to see if her head movements were slight. During this, they discovered that the baby would not be able to support his head. So they decided to have RV only switch between his main personality and the child. They also found that the average time it took him to change after being told to change was four seconds (Savoy, RL, et al, 2012, p. 2). After that, they performed the real test. The researchers had a background image that all edits found pleasing and would display on a screen for ten seconds. Then a... middle of paper......t usually tells cancer patients that they are faking. I noticed, upon further research after watching the TV show, that DID probably had to deal with it the most. In my opinion, I also think the film does a good job of showing the struggles of not only the person with IDD, but also everyone around them. I also think the show does a good job of showing how different modifications can be. One of them is a teenage girl, another is a man. One is very animalistic and the other is a child. One of them is her attacker. Since I've seen United States of Tara, I wish the authors had gone into more detail about the different VR modifications as well. We know the age and gender of the child, as well as the gender of the RV, but that's all we know. It would be interesting to know if the child and baby have been RV since she was younger or not. I think this would have enriched the basic research knowledge.
