Begin by describing the three-term contingency, and explain why it is described as the basic unit of analysis for operant behavior. In reviewing the contingencies of reinforcement and punishment, discuss how each set of contingencies has an effect on an individual's behavior. Choose a behavior from your own experience that has been reinforced, and identify whether that behavior was positively or negatively reinforced, outlining the specific three term contingency of that operant behavior. Next, choose a behavior from your own experience that has been punished and identify whether that behavior was positively or negatively punished; outline the specific three term contingency of that operant behavior. Finally, in either of those behaviors, discuss how matching law or schedules of reinforcement may contribute to the maintenance of the behavior under certain circumstances
