Chaining refers to linking behaviors together so that each behavior cues the next and is reinforced. Extinction is when reinforcers are withheld to eliminate a behavior. WolfQuest portrays chaining through the proper series of behaviors like eating, defending territory, and mating that leads to reproduction. It depicts extinction as death for behaviors like not eating or failing to defend against predators. While it shows the relationship between behaviors and consequences, an ideal portrayal would use additional examples of extinction beyond just death.
