Environmental Psychology Article Analysis Environmental psychology is concerned with real problems that arise from the environment and affect the quality of life of man and others living species. Research shows that the environment and people are one and both depend on each other to stabilize the earth. The environment influences the individual's behavior, mood, emotions, motivation, or psychological processes to adapt or adjust to environmental changes.

Environmental psychology understands that the environment and the quality of human life correspond. In conclusion, environmental psychology is important because every aspect of life revolves around the environment. Engineers, architects, designers and other disciplines can use the given research as a guideline to incorporate new designs and plans that will take into account individual needs. For example, a person with seasonal affective disorder needs adequate lighting to get enough serotonin and melatonin. Therefore, engineers, architects and designers can design and build homes with larger windows that allow in more sunlight.
