社会学习理论认为，由于对亲朋好友的攻击性在家庭中普遍存在，孩子们通过观察父母并为自己的攻击性得到加强来学习如何表现出攻击性。这一理论只考虑了环境对家族相似性的影响；然而，家族相似性也可能是遗传因素造成的。目前的研究使用双胞胎设计(134个同卵，41个异卵)来检验遗传和环境因素在多大程度上影响个体在亲密攻击方面的差异。模型拟合分析一致地表明，共同的基因解释了亲密伴侣在心理和身体上的攻击性的家族相似性；其余的差异是由独特的环境解释的。多变量模型拟合分析表明，大多数负责接受攻击性的遗传影响也对攻击性的使用负责，这表明存在参与攻击性关系的遗传倾向。这些结果挑战了解释亲密攻击中的家族相似性的主流理论。
Social learning theory posits that, because aggression against intimates runs in families, children learn how to behave aggressively through watching their parents and being reinforced for their own aggression. This theory considers only environmental influences on familial resemblance; however, familial resemblance could also be due to genetic factors. The current study uses a twin design (134 monozygotic, 41 dizygotic) to examine the extent to which genetic and environmental factors contribute to individual differences in intimate aggression. Model-fitting analyses consistently showed that shared genes explained the familial resemblance in psychological and physical intimate partner aggression; the remaining variance was explained by unique environments. Multivariate model-fitting analyses showed that most of the genetic influences responsible for the receipt of aggression were also responsible for its use, suggesting that there is a genetic predisposition to get involved in aggressive relationships. These results challenge the prevailing theory to explain familial resemblance in intimate aggression.
