This paper examines how, in many contemporary criminology texts, theories concerning criminal behavior are generally classified
according to some biological,
psychological, or
sociological perspective. It looks at how, in recent years, however, several theories of criminal behavior have appeared that make such simple categories inadequate for the complexities that have been identified in such analyses and how these new behavioral theories have specifically combined both biological and social environmental variables in their explanations of people's varying tendencies to commit crime. It reviews nine such categories of criminal behavior, followed by an analysis and summary of the research in the conclusion. Outline Introduction Review and Discussion.
