Developmental theorists have made strong claims about the fundamental prosocial or aggressive nature of the human infant. However, only rarely have prosocial behavior and aggression been studied together in the same sample. We charted the parallel development of both behaviors from infancy to childhood in a British community sample, using a two‐construct, multimethod longitudinal design.

亲社会和攻击行为：纵向研究

发展理论家对人类婴儿的基本亲社会性或攻击性本质提出了强有力的主张。然而，很少有人在同一样本中同时研究亲社会行为和攻击行为。我们使用双结构、多方法纵向设计，绘制了英国社区样本中从婴儿期到儿童期这两种行为的并行发展情况。
