but if you are studying for a test in your abnormal psychology class and need to learn about different kinds of mental disorders, this concept might be temporarily accessible. As a consequence, you might be more likely to notice the man on the bus and interpret his behavior as a sign of a mental disorder—at least until your test is over and you no longer have the goal of learning about mental illnesses
I feel like this is even dealt with in first person. When taking a psychology class, especially abnormal, people tend to start self-diagnosing because they hear in simple terms what the illness is composed of.
