Classical conditioning scenario #2: I read this story in a text entitled Learning & Behavior written by Lewis M. Barker. In the 1960s some members of the Air Force volunteered to test space suits (Dr. Barker was one of those volunteers). They were strapped to a sled that was propelled along rails and then slammed into a wall. This was done to test if the suit and helmet could take various forms of impact. Prior to "launch" there was a 40 second European style emergency vehicle horn that sounded ("dee doo, dee doo"). Dr. Barker writes that to this day when he hears emergency vehicles in Paris and London his heart rate jumps.
1. What is the US?
2. What is the UR?
3. What is the CS?
4. What is the CR?
5. What would you do to help Dr. Barker get over his aversive reaction?
