“Similarly, if a dog barks annoyingly to be let into the house from the yard and the owner usually eventually caves in, the first time the owner ignores the dog’s barking the behavior won’t stop right away. The dog will try harder and bark more. How hard he tries depends on how much he’s had to bark to get his way in the past. The existence of the extinction burst means that when we address a bad behavior by removing the reward, we have to be ready to endure a temporary worsening of the behavior.”
