This has important implications in our everyday life, where, for example, we may want to shape the behavior of a pet. Suppose a dog begs for table food, and you restrain yourself but nevertheless give in every so often. Although you tell yourself that you don’t do it all the time, and you think you are doing well, you are in fact making it harder for the dog to stop begging. We can easily think of similar scenarios with children, students, and so on. This should give us insight into our own behaviors. Is this why some of us find gambling such a persistent urge?
