A review of the general theoretical issues first explores the models of behavior used in the behavioral applications of media technology. One model involves the "Kantian psychology," which focuses on individuals and their internal perceptual and thought processes; the second draws on "Lockean psychology," which holds that behavior stems primarily from environmental stimuli; and the third model has a bioenvironmental orientation found in modern interdisciplinary theories of human behavior. The chapter advises that the behavioral model adopted by criminologists is critical to the success or failure of crime control programs, media-based or otherwise. Other than behavioral theory, the theoretical section discusses the concept of deterrence and the media as well as the history of technology and crime prevention. An analysis of crime prevention through the media considers the legal and ethical implications of the use of modern media technology in this area. Topics addressed are target areas, projects aimed at potential victims, programs aimed at potential criminals, programs aimed at the general public, and programs aimed at the criminal justice system. Some of the dangers of the new technologies are identified. 21 references.
