该研究不是直接复制，因为它没有重新创建Mischel及其同事的确切方法。研究人员仍在评估儿童期延迟满足与未来成功之间的关系，但他们的方法不同。 Watts和他的同事利用了国家儿童健康和人类发展早期儿童保育和青少年发展研究所的纵向数据，这是一个包含900多名儿童的多样化样本。特别是，研究人员将他们的分析重点放在母亲出生时尚未完成大学的儿童身上 – 这些数据的子样本更好地代表了美国儿童的种族和经济构成（尽管西班牙裔仍未得到充分代表）。一个孩子延迟满足的每一分钟预示着青春期学业成绩的微小增长，但这一增长远小于Mischel研究报告的增长。此外，当控制家庭背景，早期认知能力和家庭环境等因素时，这种关联几乎消失了。

The study was not a direct copy because it did not recreate the exact method of Misschel and his colleagues. Researchers are still assessing the relationship between delayed child satisfaction and future success, but their approach is different. Watts and his colleagues used longitudinal data from the National Institute of Child Health and Human Development Early Childhood Care and Adolescent Development, a diverse sample of more than 900 children. In particular, the researchers focused their analysis on children whose mothers had not completed college at birth – a subsample of these data better represents the ethnic and economic composition of American children (although Hispanics are still underrepresented). Every minute that a child delays to meet indicates a small increase in adolescent academic performance, but this growth is much smaller than the growth of the Mischel study. In addition, this association almost disappears when controlling factors such as family background, early cognitive ability, and family environment.”
