Extracted text: Your dog Hans loves to ride in the car. Whenever anyone picks up a set of keys he races for the door. When your grandmother, who is afraid of dogs, arrives for a visit, Hans is not allowed to ride in the car. By the end of her two-week visit, he has ceased going to the door when the keys come out. However, after a brief vacation away from home, he's back at the door again as soon as he hears the keys. Why? Generalization has occurred. Counterconditioning occurred during the vacation. Grandma produced external inhibition in the dog. Spontaneous recovery has occurred.

Antonio was born in 1986 and is a part of the "millennial" generation, finding it more difficult to get a job after college with full time employment, as he graduated during the 2008 recession. To the extent that their ideas about life are tied to their time and culture of birth, the differences that exist between Matteo and Antonio's attitudes and values can be largely attributed to differences. reference group idiosyncratic cohort age
