In architecture, spaces are more or less defined by boundaries. A psychological phenomenon directed towards and evidenced by the architectural environment can be described as experiential qualities. These affective qualities have the potential to bring out an emotional response to architectural environments, which can be either a conscious judgment or a subconscious mood-changing effect. Psychology and architecture are a vast and diverse subject of study. By exploring the field of environmental psychology, we understand the physical and behavioral effects between people and their physical environment that become quite complex when acoustic characteristics (noise), elements of light and color (warm or cold, shade or hue ), texture (materials and surface) are taken into account.

Space, form and light are elements that are often incorporated deliberately or unconsciously for aesthetic or practical reasons, but which more clearly give creatures meaning, purpose and stability in the midst of an ever-changing physical universe. evolution and apparent chaos..
