 All right, so spontaneous recovery of a respondent behavior I'm allergic to dogs and the dog would bark and the dander and everything would make me sneeze, right? So the dog would bark and I would sneeze the dog bark and I would sneeze One day I drove by a dog park and was far enough away that all these dogs were barking and I wouldn't sneeze and They would continue to bark and I wouldn't sneeze and then I eventually moved away and Heard the neighbors dog barking and I would sneeze That's the spontaneous recovery of a respondent behavior Classical condition don't ring the doorbell to my neighbor's house
