Psy240 chapter 5: trauma, anxiety, obsessive-compulsive, and related disorders. Fight-or-flight response: set of physical and psychological responses that help us fight a threat or flee from it. Activation of two systems controlled by the hypothalamus. Autonomic nervous system (in particular the adrenal-cortical system) Posttraumatic stress disorder (ptsd) and acute stress disorder. Ptsd and acute stress disorder are the consequences of experiencing extreme stressors, referred to as traumas. Depersonalization: persistent or recurring experiences of feeling detached from one"s mental processes or bodies. Derealization: persistent or recurring experiences of unreality of surrounding. Diagnosis requires the presence of four types of symptoms. Persistent avoidance of situations, thoughts, or memories associated with the trauma. Negative changes in thought and mood associated with the event. Many people with ptsd experience some symptoms of disassociation, a process in which different facets of their sense of self, memories, or consciousness become disconnected from one another.
