A psychobiological model of PTSD draws connections among the symptoms and neural mechanisms of _______, behavioral sensitization, and _______.

Question

Quizplus · Accepted Answer

The psychobiological model of PTSD links the symptoms of fear and anxiety to fear conditioning, where an individual learns to associate a previously neutral stimulus with a traumatic event. This also involves behavioral sensitization, where repeated exposure to traumatic stimuli makes an individual more sensitive to them over time. Additionally, the model emphasizes the neural mechanisms involved in fear learning and extinction, where certain regions of the brain (e.g. amygdala, prefrontal cortex) play key roles in the formation and maintenance of fear-related memories.
