Understanding the Mechanisms Through Which an Influential Early Childhood Program Boosted Adult Outcomes
利用佩里学前项目的实验数据，分析认知和人格技能如何作为中介机制，解释该项目对参与者成人结果的提升作用，发现人格技能的变化解释了大部分成人处理效应。
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 skills 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 skills explain a sizable portion of adult treatment effects.
