The process of learning involves both direct and indirect reinforcement. For example, a child may be praised (direct reinforcement) or observe others being rewarded for criminal behaviour (vicarious reinforcement). Criminal behaviour is therefore learned in the same way as any other behaviour. Sutherland believed the strength of these influences depends on factors such as frequency, duration, and emotional intensity of the associations. He argued that general needs (e.g. money) do not explain crime, as not everyone with those needs becomes a criminal. Overall, DAT explains how individuals may develop criminal behaviour through exposure to deviant values, attitudes, and behaviours within their social environment.
