My article is titled: "Voluntary Switching Between Identities in Dissociative Identity Disorder: A Functional MRI Case Study" and is written by RL Savoy, BB Frederick, AS Keuroghilan and PC Wolk. The article is about dissociative identity disorder (DID) and was previously called multiple personality disorder (MPD). DID is when a person has multiple personalities, or alterations, in a single body. Alter egos are your own person, with your own characteristics, age and even gender. In this article, one participant had an adult, infant, and childlike personality. This article presents research on what happens in the brain when a person switches to a different alter ego. Wolk, one of the authors, has been working with one patient, RV, for over 20 years (Savoy, R.L., et al, 2012, p. 1). RV, derived from the nickname Research Volunteer, has DID and is actually capable of voluntarily switching between alters. She had two other alter egos, a 4-6 year old girl and a non-verbal boy (Savoy, RL, et al, 2012, p. 2). To conduct this research and study her brain during exchanges, she was placed in an MRI. They did some trail runs and preliminary tests to make sure it could change environments like fMRI and to see if the head movements were only slight. During this, they discovered that the child's alter ego would not be able to support his head, therefore, they decided to have RV only switch from his main personality to that of the child. They also found that the average time it took to change after being told to change took four seconds (Savoy, R.L., et al, 2012, p. 2). Next, they conducted the real test. The researchers had a background image that all alters found pleasant and displayed on a screen for ten seconds. So, a… middle of paper… typically tells cancer patients that they are faking it. I noticed, with further research after watching the TV show, that DID probably had to deal with it the most. In my opinion, I also think it does a good job of showing the difficulties of not only the person with DID, but everyone around them. I also think the show does a good job of showing how different alter egos can be. One of them is a teenager, the other 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 writers would also go into more detail about RV's different alter egos. We know the age and gender of the child and the gender of the camper, but that's all we know. It would be interesting to know whether the boy and the baby have been campers since she was younger or not. I think this would have enriched the research knowledge base.
