本研究的目的是研究稳定性和变化的遗传和环境的影响反应性（冲动和情感）和主动性（计划和工具）的攻击从童年到青春期早期。样本来自南加州大学（USC）正在进行的一项关于反社会行为风险因素的纵向双胞胎研究。双胞胎在两种情况下进行测量：9-10岁（N= 1，241）和11-14岁（N=874）。反应性和主动性攻击行为由父母评定。反应性攻击的稳定性是由于遗传和非共享的环境影响，而主动攻击的连续性主要是遗传介导的。两个场合之间的反应性和主动性侵略的变化主要是由非共享的环境影响，虽然一些证据表明，新的遗传变异在第二次发现的两种形式的侵略。这些结果表明，主动和反应性侵略不同，在其遗传和环境的稳定性，并提供了进一步的证据反应性和主动形式的侵略之间的一些区别。Agr.行为举止。35：437-452，2009.© 2009 Wiley利斯公司
The aim of this study was to examine stability and change in genetic and environmental influences on reactive (impulsive and affective) and proactive (planned and instrumental) aggression from childhood to early adolescence. The sample was drawn from an ongoing longitudinal twin study of risk factors for antisocial behavior at the University of Southern California (USC). The twins were measured on two occasions: ages 9–10 years (N=1,241) and 11–14 years (N=874). Reactive and proactive aggressive behaviors were rated by parents. The stability in reactive aggression was due to genetic and nonshared environmental influences, whereas the continuity in proactive aggression was primarily genetically mediated. Change in both reactive and proactive aggression between the two occasions was mainly explained by nonshared environmental influences, although some evidence for new genetic variance at the second occasion was found for both forms of aggression. These results suggest that proactive and reactive aggression differ in their genetic and environmental stability, and provide further evidence for some distinction between reactive and proactive forms of aggression.
