A growing literature establishes that high quality early childhood interventions targeted toward disadvantaged children have substantial impacts on later life outcomes. Little is known about the mechanisms producing these impacts. This paper uses longitudinal data on cognitive and personality traits from an experimental evaluation of the influential Perry Preschool program to analyze the channels through which the program boosted both male and female participant outcomes. Experimentally induced changes in personality traits explain a sizable portion of adult treatment effects.
越来越多的文献表明，针对弱势儿童的高质量早期儿童干预措施对其后期生活结果有重大影响。对于产生这些影响的机制却知之甚少。本文利用一项对具有影响力的佩里学前教育项目进行实验评估所获得的关于认知和人格特质的纵向数据，来分析该项目促进男性和女性参与者取得良好结果的渠道。实验诱导的人格特质变化解释了相当一部分成人治疗效果。
