This study estimates the effect of physical punishment on the cognitive development of 1,167 low-income Colombian children (Mage = 17.8 months old) using 3 analytic strategies: lagged-dependent variables, a difference-in-differences-like approach (DD), and a novel strategy combining matching with a DD-like approach. Across approaches, physical punishment at ages 9-26 months predicted reductions in children's cognitive development of 0.08-0.21 SD at ages 27-46 months. These results, plus null results of falsification tests, strengthen the argument that physical punishment leads to slower cognitive growth and illustrate the utility of alternative statistical methods to reduce problems of selection bias in developmental research.

体罚作为早期认知发展的预测因子：来自计量经济学方法的证据。


本研究使用 3 种分析策略估计了体罚对 1,167 名低收入哥伦比亚儿童（Mage = 17.8 个月大）认知发展的影响：滞后因变量、双重差分法 (DD) 和一种将匹配与类似 DD 方法相结合的新颖策略。各种方法中，9-26 个月大的体罚预测 27-46 个月大的儿童认知发展会下降 0.08-0.21 标准差。这些结果加上证伪测试的无效结果，强化了体罚导致认知增长缓慢的论点，并说明了替代统计方法在减少发展研究中选择偏差问题方面的效用。 （PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
