Document Summary
When you have conscious experience, you tend to be more sure of something. People will learn to calm down their fear when they"re in the very specific controlled context. This leads to a problem in treating ptsd patients. Some are just generally traumatized by everything, but some associate their trauma with a certain stimulus. Laboratory context is very different from the environment in which they acquired the trauma. Aba paradigms: context a (electric shocks) -> context b (different room, not bad, unlearning) -> context a (relearned fear) Abc paradigms: context a (beethoven music, electric shocks, fear) -> context b (hip hop music, no shocks, no fear) -> context c (jazz music, still fear) In context b (hip hop), gradually remove shocks works better than suddenly removing shocks; you realize that it"s changing. Distribution: a list of values (e. g. , scores on an exam, rate of action potentials)
