Juan Is a Freshman at a Local University

Juan is a freshman at a local university. He gets up at the same time each day and follows the same pattern: showering and shaving, dressing, and checking his backpack for required books, notebooks, and pens. Early in the first semester, this behavior took approximately 30 minutes. As the semester progressed, Juan spent more and more time checking and rechecking his backpack to make sure he had everything he needed. Toward the end of the semester, Juan was always late for his first class because of his "thoroughness." A psychologist might conclude that Juan's behavior is

A) typical for a conscientious student.
B) dysfunctional even if not distressful.
C) not abnormal because it does not cause problems for others.
D) normal according to the "goodness-of-fit" model.
