摘要
同人类的许多行为一样,攻击具有遗传学基础.随着行为遗传学的兴起,研究者主要运用双生子研究与收养研究模式对攻击的遗传机制进行了大量研究,发现攻击,特别是严重的或终生持续的攻击或反社会行为具有明显遗传性;遗传与环境在攻击发生发展中具有交互作用,消极环境因素在高攻击性遗传危险的个体身上效应更大,攻击或暴力遗传危险使处于不利环境中的个体更可能出现攻击与反社会行为.这些研究发现对攻击干预具有重要实际价值.本文最后提出了在理解和解释遗传对人类攻击的作用时需要注意的几个问题.
Like most of the human behaviors, aggression has its genetic bases. Behavioral genetics emerged in 1990s provedes two main kinds of designs to investigate the genetic bases of human aggression, that is , twin study and adoption study. The behavior genetic research indicated that aggression, especially serious or life - course - persistent aggression or antisocial behavior was quite heritable. There were interactions between genetic factors or genotype and environment, specifically, there was a stronger impact of negative environment on aggression among a subpopulation at higher genetic risks than among individuals at lower genetic risks,and among those with environmental adversities,some genetic factors may be more likely to lead to aggression and antisocial behaviors. All of the findings had thief implication for aggression intervention. At last, several caveats were suggested in understanding and interpreting the heredity of human aggression.
