Personal space in environmental psychology refers to the distance that individuals prefer to be from each other. It is the physical space around an individual that they consider to be their own and is influenced by cultural and situational factors. Personal space is not necessarily an area that an individual has control over or decorates according to their preferences, nor is it an area that one defends from others.
