1. Sick social cycle (victim’s punishment model)—define it and give an example 

• Draw the two contingency diagrams for your example. 

• Draw the circular diagram of the sick social cycle. 

2. Now please fill in the diagram for your entire sick social cycle. (The contingency for the perpetrator goes in the top row, and the contingency for the victim goes in the second row.) 

• Make sure the first contingency is a negative reinforcement contingency, where the inappropriate behavior of the perpetrator is reinforced by escape from an aversive condition (a negative reinforcer). 

• Make sure the second contingency is a positive punishment contingency where the appropriate behavior of the victim is punished.
