Previous studies have shown how context affects human behavior and cognitive functions. However, less is known about how extreme situations impact on our behavior when we are faced with unusual events such as natural disasters. Humans might actively address or turn away from a critical event, or not respond at all. One important hypothesis would be that various types of pressure increase the likelihood that behavior is determined by pre-potent responses, or pre-existent biases. However, it is also possible that under extreme situations the pre-potent responses become less efficient, for instance, if stress leads to chaotic or inaccurate behavior. As a first step toward elucidating the relationship between extreme situations and human behavioral tendencies, we conduct a survey to investigate the perception of extreme situations. We examined what kinds of situation subjects regard as extreme. Our data identify key factors and aspects about the human perception of extreme situations.
