None of these definitions provides a complete description of abnormal behavior. The legal definition of abnormality declares a person insane when he is not able to judge between right and wrong, but this criterium is not used by psychologists. In this paper, I will try to explain what we the society views as abnormal behavior.

Every human group lives by a set of norms-rules that tell us what it is “right” and “wrong” to do, and when and where and with whom. Such rules circumscribe every aspect of our existence, from our most far-reaching decisions to our most prosaic daily routines.

Consider, for example, the matter of how close we stand or sit to a person we are talking to. This is something that is taken for granted by people within a society, but it differs widely among societies. In North America, when two people who do not know one another well are conversing, they will stand about 3 feet apart, but in South America they stand much closer, and in Asia, much farther apart. In one study, Japanese, American, and Venezuelan students were asked to have a five-minute conversation with a stranger of the same sex and nationality. The Japanese sat about 40 inches apart; the Americans, 35 inches; the Venezuelans, 32 inches (Sussman & Rosenfeld, 1982). Arabs come even closer than South Americans. According to Edward Hall (1976), the primary investigator of this subject of “personal space”:

In the Arab world, you do not hold a lien on the ground underfoot. When standing on a street corner, an Arab may shove you aside if he wants to be where you are. This puts the average territorial American or German under great stress…..Years ago, American women in Beirut had to give up using streetcars. Their bodies were the property of all men within reach. What was happening is even reflected in the language. The Arabs have no word for trespass.
