Following my last question, I have searched for some information about criminal attitudes in the criminological and forensic psychological literature. And I found two very interesting theories of criminality. One is the “Differential Association”, proposed by Sutherland, is anyone could elaborate more for me?

Not at all.

Thank you so much.

Sure. Briefly speaking, Sutherland’s (1947) model stressed the role of social learning influences in the acquisition of criminal behavior, through exposure to antisocial role models with whom the individual associates, and a resultant formation of antisocial attitudes.
