Criminal behavior is a complex, extremely common, and costly problem for society. Not all people who engage in criminal behavior are the same in terms of etiological pathways, versatility, continuity, type of behavior, and amenability to treatment. There is little agreement about the causal origins of criminal behavior. However, research identifies a range of factors that are involved in the development of criminal behavior, including environmental (e.g., neighborhood), constitutional (e.g., personality), and neurobiological (e.g., emotion, attention, and executive functions). This program will cover a range of theoretical and empirical material to begin to understand the development of the "criminal mind."
