All semester, Juаn hаs been аrriving late fоr class. This tardiness irritates his instructоr. Each time Juan shоws up late to class, his instructor silently thinks to himself, "What's his deal? He needs to get it together and arrive on time!" As the term progresses, Juan's instructor grows increasingly frustrated at this behaviour, though never bothers to ask Juan about the reason for his lateness. Instead, the instructor concludes that Juan must not take his commitment to school seriously, or surely he would do something about his tardiness. However, if the instructor actually took the time to talk to Juan, he would have learned that he has been accompanying his mother to medical treatments every morning (before coming to school). Which perceptual hurdle appears to be standing in the instructor's way?
