ABSTRACT
This chapter examines a number of criminological and psychological perspectives and discusses how these might help with the policing of cyber and other network-related crimes. It explains how some traditional and psychological criminological theory might apply within the novel contexts provided by a digital network environment. Similarly, differential association theory is often associated with the behaviourist tradition in psychology. The theory of neutralisation was developed by Graham Sykes and David Matza in the 1950s as part of their work into Sutherland's differential association. Criminology draws upon a wide range of disciplines, for example, sociology, psychology and history. A major criminological theory is social learning theory. Routine activities theory was developed by the criminologists Ron Clarke and Marcus Felson in the 1980s and 1990s. When examining theories of deindividuation it is important to see online environments within the wider context of the personal and social environments we inhabit.
