family as a source of control was in marked contrast to the emphasis on economic circumstances as a source of criminogenic motivation at the time. Although he acknowledged motivational forces by stating that, "...some delinquent behavior results from a combination of positive learning and weak and ineffective social control" (1958: 4), he adopted a control-theory position when he proposed that, "...most delinquent behavior is the result of insufficient social control..." Walter Reckless Walter Reckless (1961) developed containment theory by focusing on a youth's self-conception or self-image of being a good person as an insulator against peer pressure to engage in delinquency. inner containment = positive sense of self; outer containment = supervision and discipline. This inner containment through self-images is developed within the family and is essentially formed by about the age of twelve. Outer containment was a reflection of strong social relationships with teachers and other sources of conventional socialization within the neighborhood. The basic proposition is there are "pushes" and "pulls" that will produce delinquent behavior unless they are counteracted by containment. The motivations to deviate as pushes are: discontent with living conditions and family conflicts; aggressiveness and hostility, perhaps due to biological factors; and frustration and boredom, say arising from membership of a minority group or through lack of opportunities to advance in school or find employment; and the pulls are: delinquent peers, and delinquent subcultures. David Matza An analysis of 'neutralization' was developed by Sykes and Matza (1957) who believed that there was little difference between delinquents and non-delinquents, with delinquents engaging in non-delinquent behavior most of the time. They also asserted that most delinquents eventually opt out of the delinquent lifestyle as they grow older, suggesting that there is a basic code of morality in place but that the young are able to deviate by using techniques of neutralization, i.e. they can temporarily suspend the applicability of norms by developing attitudes "favorable to deviant behavior". The five common techniques were: denial of responsibility (I couldn't help myself) denial of injury (nobody got hurt) denial of victim (they had it coming) condemnation of the condemners (what right do they have to criticize me?) appeal to higher loyalties (I did it for someone else). Later Matza (1964) developed his theory of "drift" which proposed that people used neutralization to drift in and out of conventional behaviour, taking a temporary break from moral restraints. Matza based his "drift"
