members as they increase in size, their studies illustrated that large schools had a similar number of behavior settings to that of small schools. This resulted in the students' ability to presume many different roles in small schools (e.g. be in the school band and the school football team) but in larger schools, there was a propensity to deliberate over their social choices. In his book Ecological Psychology (1968), Barker stresses the importance of the town's behavior and environment as the residents' most ordinary instrument of describing their environment. "The hybrid, eco-behavioral character of behavior settings appear to present Midwest's inhabitants with no difficulty; nouns that combine milieu and standing behavior are common, e.g. oyster supper, basketball game, turkey dinner, golden gavel ceremony, cake walk, back surgery, gift exchange, livestock auction, auto repair." Barker argued that his students should implement T-methods (psychologist as 'transducer': i.e. methods in which they studied the man in his 'natural environment') rather than O-methods (psychologist as "operators" i.e. experimental methods). Basically, Barker preferred fieldwork and direct observation rather than controlled experiments. Some of the minute-by-minute observations of Kansan children from morning to night, jotted down by young and maternal graduate students, may be the most intimate and poignant documents in social science. Barker spent his career expanding on what he called ecological psychology, identifying these behavior settings, and publishing accounts such as One Boy's Day (1952) and Midwest and Its Children (1955). Natural environment research findings Environmental psychology research has observed various concepts relating to humans' innate connection to natural environments which begins in early childhood. One study shows that fostering children's connectedness to nature will, in turn, create habitual pro-ecological behaviors in time. Exposure to natural environment may lead to a positive psychological well-being and form positive attitudes and behavior towards nature. Connectedness to nature has shown to be a huge contributor to predicting people's general pro-ecological and pro-social behaviors. Connectedness to nature has also been shown to benefit well-being, happiness, and general satisfaction. "Nature-deficit disorder" has recently been coined to explain the lack of connectedness to nature due to a lack of consciousness identification and nature disconnect. Further research is required to make definitive claims about the effects of connectedness to nature. Applications Impact on the built environment Environmental psychologists rejected the laboratory-experimental paradigm because of its simplification and skewed view of the cause-and-effect relationships of human behaviors and experiences.
