1) A good many factors influence whether a situation is seen as too crowded. (2) Duration is one factor. (3) For instance, people typically find it easier to tolerate a brief exposure to high-density conditions such as a ride on a crowded elevator than prolonged exposure on a cross-country bus. (4) A second factor is predictability. (5) People typically find crowded settings even more stressful when they are unable to predict them. (6) A third factor has to do with frame of mind. (7) There are times when individuals welcome solitude and other times when they prefer the presence of others.
(8) A fourth factor involves the environmental setting. (9) People generally report that they can tolerate crowding better in impersonal settings such as a shopping center or an airline terminal than in a home or apartment. (10) Finally, people's attitude toward a situation determines how they feel about crowding. (11) If people are fearful and antagonistic
— or excited and friendly —crowding tends to intensify the feelings. (12) Crowding makes a doctor's waiting room and a subway car all the more unpleasant, whereas it makes a football game and a party all the more enjoyable. (13) And even though a crowded New York subway car turns people off, a crowded San Francisco cable car, crammed with people hanging over the sides, is defined as a "tourist attraction."
