Environmental Psychology is an area of Psychology that studies the interrelationship of man with the environment in its physical and social context. But what characterizes an environment in Psychology. The definition of environment used in disciplines such as physics and natural sciences is different from the concept of environment in psychology. We can define the environment as something real that potentially has some effect on the behavior of a single individual or group of individuals, the environment is never neutral, since the absence or presence of certain elements always enhances a message. This studied environment can be your home, your neighborhood, your city, your school. The individual-environment relationship is a dynamic relationship, as there is a reciprocity of influences, the individual shapes the environment so that it meets his needs. The concern of Environmental Psychology is how man, from his perceptions, man perceives and acts on the environment and at the same time how that same environment is influencing the individual's daily behavior.
