The study of personal space is important. Proxemic behavior is not only a form of self-defense, it is also a part of the unconscious that controls behavior and interaction between human beings. Personal space is essential for people because it warns when someone is too close and could cause harm to another. Some studies try to explain how proxemic behavior works and what factors can influence it. For example, previous experiments have found that people move away more when faced with tall people than when faced with short people. This knowledge of personal space and how it works is important because it shows how to behave towards each person and how close a person can be without causing discomfort. Personal space could be defined as the distance required between people when interacting with others. Hayduk (1983) describes personal space as a sensitive entity that changes depending on the situation. Therefore, when a person invades another's personal space, the violated person comes to feel vulnerable, uncomfortable, or irritated as a response to the violation of his or her proxemics. In other words, personal space is the distance necessary for interaction and acts depending on the situation and the factors that influence it. The first factor that affects personal space is height. Previous studies state that proxemics are greater when people walk towards tall people than when they walk towards short people. This notion is supported by Harnett, Bailey, and Hartley (1974, p. 134) who demonstrated that “Both males and females maintained twice as much distance between themselves and the tall object person as between themselves and the short object person.” .
