There have been efforts to understand human behavior from the 1960s to the present day. Understanding the environment and behavioral contexts is the first step towards analyzing how humans respond to these environments and behavioral contexts. The field of Environmental Psychology aims to explain the interdependencies between people and the space around them. Because of the wide range of information, a subject's behavior can be predicted - for the moment and not accurately - within spaces with limited variables at a time. School, squares and housing in different economic and social classes are some of them.Among the first experiments carried out by the Behaviourists, those of Skinner, Pavlov and Watson were distinguished. The subjects they observed were mice, dogs and babies respectively and their experiments were conducted under specific conditions. Their aim was to draw conclusions, frame the subjects' reactions and relate them to humans as well. The incomplete variables and the limited environments are the reasons they were criticized, giving rise to the Anti-Behaviorism movement, which aimed to highlight the incomplete methodology of the Behaviorists and to point out factors such as a person's culture and history and to give emphasis to free will. The role of architecture begins to be affected when specific reactions to specific architectural triggers begin to be observed, which range from the configuration of a domestic space to the urban planning of a city. Thus is born the spectrum of architectural determinism which extends to environmental possibilism. Theories that propose the level of influence of architecture on human behavior and psychology. In need of analyzing these two for better design of buildings, parks, cities, squares, Bill Hillier's theory "Space Syntax" was developed proposing ways of influencing the movement of the mass in a space. It proposes a way of studying this space which allows us to see clearly the nuclei of mass concentration. This theory has been applied to the design of Trafalgar Square in London, the analysis of 4 universities in Chile which are analysed in this research paper and many other studies on the architectural, urban planning and design solution of spaces. Finally, the power of shape in the field of Architecture in influencing the behavior and perhaps psychology of the individual is analyzed through the research work of M. Iliomarkakis.
