Document Summary
Escape behavior performance of the behavior terminates the aversive stimulus, avoidance behavior performance of the behavior prevents the aversive stimulus from occurring. Shuttle avoidance procedure an animal has to shuttle back and forth in a box in order to avoid an aversive stimulus. Typically one learns to escape an aversive stimulus, then avoid it. Negative reinforcement = removal of an aversive stimulus following a response, resulting in an increase in the strength of that response. Two-process theory of avoidance = two processes are involved in learning an avoidance response (mowrer) One-process theory of avoidance = the act of avoidance is negatively reinforced simply by the lower rate of aversive stimulation with which it is associated. Avoidance learning is the fundamental process in the development and maintenance of a phobia. After repeated exposure trials, animals appeared to show no evidence of fear but continued to make the avoidance response anyway.
