Factors influencing people evaluations of the environment can be grouped into three different categories (Peron & Falchero, 1994): 1) Individual factors, such as age, personality traits, social structural variables, familiarity with a place and expectancies with regard to a place; 2) Physical factors, mainly related to the natural vs. built distinction. Both the presence of natural features within a built environment and the presence of human-made features within a natural environment seem to increase people's positive evaluations (Hartig & Evans, 1993; Bonnes, et al., 2001); 3) Factors involving people-environment relations: among these we can identify the degree to which a place is capable to serve its goals, the degree with which it is functional in supporting individual's scopes.
