This review of research on perception of the environment is part of a series designed to supplement undergraduate geography courses. In the past decade there has been a remarkable increase in research related to man-environment interaction. Much of this research has centered on how the individual perceives the environment and is characterized by a trend toward psychological geography infused with behavioral science techniques. The report reviews current research and is organized according to a scale. Starting at the smallest scale, that of an individual in relation to another individual, it examines man and his relation to progressively larger sections of his environment. Areas of review include perception of personal space, room geography, larger architectural space, roads and pathways, neighborhoods and districts, the city, larger conceptual regions, countries, and the world. Also included is a list of readings related to each area of review. (Author/DE)
