背景：恐惧条件反射不良是成人精神病和犯罪的特征，但尚不清楚它是否与儿童早期的攻击/反社会行为有关。方法：采用差异、部分强化条件反射范式，记录200名3、4、5、6和8岁的男性和女性儿童的皮肤电活动。在8岁时收集反社会/攻击性和过度活跃-注意力不集中的措施。结果：在3-8岁时，不良的真皮恐惧条件反射与8岁时的攻击行为有关。结论：恐惧条件反射不良与攻击性之间的关系发生在儿童时期。增强的皮肤恐惧条件反射可能会保护儿童免受未来的攻击性/暴力行为的影响。杏仁核功能异常，通过恐惧条件反射间接评估，可能是影响儿童攻击性发展的因素之一。
Background:Poor fear conditioning characterizes adult psychopathy and criminality, but it is not known whether it is related to aggressive/antisocial behavior in early childhood.Methods:Using a differential, partial reinforcement conditioning paradigm, electrodermal activity was recorded from 200 male and female children at ages 3, 4, 5, 6, and 8 years. Antisocial/aggressive and hyperactive-inattentive measures were collected at age 8.Results:Poor electrodermal fear conditioning from ages 3 to 8 years was associated with aggressive behavior at age 8 in both males and females.Conclusions:Results indicate that the relationship between poor fear conditioning and aggression occurs early in childhood. Enhanced electrodermal fear conditioning may protect children against future aggressive/violent behavior. Abnormal amygdala functioning, as indirectly assessed by fear conditioning, may be one of the factors influencing the development of childhood aggression.
