Back to Assignment Average: /3 Attempts 4. Etiology of dissociative disorders Etiology of dissociative disorders Biological factors Aa Aa Amnesia is common in dissoclative disorders, and research has shown that differences in some brain structures may create a biological susceptibility to amnesia. Which of the following statements best describes the findings about how brain function and structure may contribute to dissociative amnesia? O Brain-imaging studies have found increased metabolism in the hippocampus, which is responsible for memory O Brain-imaging studles have found reduced activity and metabolism in the prefrontal cortex of people with O Dissociative disorders are frequently seen in people born with an abnormal and deformed parietal cortex, formation, in patients with a confirmed dissociative disorder diagnosis. confirmed dissociative disorder diagnoses. resulting in reduced cortical volume. Psychological factors Psychodynamic theory and the post-traumatic model provide most of the contemporary explanations of the psychological factors contributing to dissociative disorders such as dissociative identity disorder. For example, a large percentage of people with dissociative identity disorder experienced traumas such as physical or sexual abuse as children. Psychological defense mechanisms such as repression are also assumed to contribute to the other dissociative disorders as well. Which of the following statements is the best description of how psychadynamic theory would explain depersonalization or derealization experiences? Subconscious mechanisms protect the person from trauma, and help them cope with it, by creating an illusion the experience is happening to someone else, and invoking feelings of compassion and empathy for that other person Experiences of depersonalization/derealization are specific to developmental stage. Children are less likely to experience them than adults, because they are naturally more creative and imaginative than adults. The subconscious mind separates the person and their identity from the experience and denies the experience is happening at all without actually repressing the thoughts and feelings as a way to protect the person from the negative consequences of the trauma. Social and sociocultural factors The sociocognitive model of DID covers both the social and sociocultural dimensions of the multipath model. A combination of social and cultural forces act upon the identified patient to create an iatrogenic effect, where treatment causes the disorder The rate of DID has gone through extreme increases and decreases in the recent past, far beyond the historic incidence and prevalence rates. Which of the following social/cultural factors is thought to have caused this spike- and subsequent drop-in incidence rate? O Social crises such as the civil rights movement caused significant ethnic stress in society in the 1960s and 1970s, resulting in more individual traumatic or stressful events for people, which caused an increase in cases of DID in vulnerable individuals. O The significant threat of a global nuclear war between Russia and the United States increased stress levels across society, particularly on parents, causing an increase in the physical and sexual abuse of children, resulting in the increased rate of DID O The use of hypnosis and methods of retrieving "repressed" memories used by therapists may create iatrogenic effects on the patients with which they are used, causing them to display the expected appropriate symptoms as a result.

1. The correct answer is Option 1. Brain imaging studies indicate increased metabolism in the hippocampus among patients of dissociative amnesia.
2. The correct answer is Option 3. The psychodynamic theory asserts that the subconscious mind separates the person and the identity from the experience in dissociative amnesia.
3. The correct answer is Option 3. According to the socio-cultural model, the use of hypnosis and methods of retrieving repressed memories used by therapists may create iatrogenic effects on the patient.
