The role of trauma and the experience of unusual states of awareness or identity in the dissociative disorders have led psychologists to explore the relationship between dissociation and post-traumatic stress, on the one hand, and hypnosis, on the other. Briefly summarize the results of this research.
What will be an ideal response?
Ans: The research shows that dissociation is separate both from post-traumatic stress and hypnotic suggestibility. A study of people who had been tortured showed that while they all experienced PTSD, they varied greatly in the number of dissociative experiences. The number of dissociative experiences related positively to left frontal lobe activity and negatively to right frontal lobe activity, suggesting that dissociation reflected changes in brain networks integrating the linguistic and the emotional aspects of experiences. Hypnotic suggestibility appeared largely unrelated to dissociation, perhaps because hypnotic states are entered voluntarily, whereas dissociative states are involuntarily.
