This book covers a large selection of the recent literature on environmental psychology. It defines the discipline and then goes on to provide many examples of its application and controversies. Much of the text consists of critical evaluations of a large number of studies of the relationship between behavior and environment, although more of it seems to be concerned with general person-environment relationships than with the specific effect of the urban environment upon people. The author optimistically suggests that people can learn to adapt successfully to much higher densities if this becomes necessary, yet concludes that environmental psychology cannot yet answer the question of what is an 'optimum' environment for people or what is the 'best' person for any environment. The state of the art is still primitive and the results of studies in environmental psychology are contradictory and open to much interpretation. However, they may delineate the range of possibilities that lie open, and may guide planners to make more rational environmental choices in the future.
