This report compares the effects (concurrent and lagged) of the anticipated rewards and costs of violent crime on engagement in severe violence in a sample of male juvenile offenders (N = 1,170; 42.1% black, 34.0% Hispanic, 19.2% white, and 4.6% other; ages 14-18 at baseline). Anticipated rewards (social approval, thrill) are more predictive of concurrent severe violence than are anticipated costs (social disapproval, risk of punishment). The analysis finds no evidence that perceptions of the rewards and costs of violent crime influence engagement in severe violence 6 months later. The results support the view that adolescence is a time of heightened reward salience but raise doubt about the longitudinal predictive validity of perceptions about crime during this time of life.
本报告比较了暴力犯罪预期收益和成本(同时期和滞后)对男性青少年罪犯样本(N = 1,170;42.1%为黑人,34.0%为西班牙裔,19.2%为白人,4.6%为其他;基线年龄为14 - 18岁)严重暴力行为参与度的影响。与预期成本(社会不认可、惩罚风险)相比,预期收益(社会认可、刺激感)更能预测同时期的严重暴力行为。分析发现,没有证据表明对暴力犯罪收益和成本的认知会在6个月后影响严重暴力行为的参与度。研究结果支持了这样一种观点,即青春期是奖励显著性增强的时期,但也对这一人生阶段犯罪认知的纵向预测有效性提出了质疑。
