Its main purpose is to reduce the future frequency of the behavior by applying an aversive stimulus after the behavior occurs. Regarding the use of aversive stimuli, three general types of instrumental situations are usually distinguished: punishment training, escape training, and avoidance training (for a fourth type called the preservation procedure see Church, 1963). If that context is subsequently paired with an aversive stimulus, such as an electric footshock (indicated by the lightning symbol), it will yield an association between the context and shock; this process is called context conditioning (middle panel).
