Cognitive behavior therapy is based on the assumption that behavior depends on thoughts and feelings. Based on "cognitive sets" and "emotional states" same situations can trigger different behaviors. Changes in everyday settings, having to wait or participating in controversial discussions can either cause a calm or an emotionally charged response. Therapists try to reduce stress-responses and  to change pessimistic thinking by optimistic thoughts. Photo-sequences of positive and negative conflict solutions (Jed Baker), social cartoons of contingency maps, role play and video modeling  (Vera Bernard-Opitz, Christos Nikopoulos) are used to visualize alternative problem solutions. Images, such as "Social Detective" (Michelle Garcia-Winner) or "Thought Filters" (Joel Shaul) can facilitate self-reflection.
