To illuminate how within-family differences in achievement may emerge, this study examined sibling experiences in middle childhood as predictors of sibling differences in college graduation. First- and second-borns from 152 families reported on their experiences with siblings and parents at ages 11.80 (SD = 0.56) and 9.22 (SD = 0.90), respectively, and on their educational attainment at about age 26. Significant childhood predictors of sibling differences in college graduation status included low sibling warmth, fathers' differential time spent with siblings, and perceived unfair differential treatment by parents. Findings suggest long-term implications of early sibling dynamics for educational attainment and provided novel insights into families' role in achievement.
为了阐明家庭内部成就差异是如何产生的，本研究考察了儿童中期兄弟姐妹经历对兄弟姐妹在大学毕业方面差异的预测作用。152 个家庭中的长子和次子分别在 11.80 岁（SD=0.56）和 9.22 岁（SD=0.90）时报告了他们与兄弟姐妹和父母的经历，并在大约 26 岁时报告了他们的教育程度。预测兄弟姐妹在大学毕业状态上差异的显著儿童期因素包括兄弟姐妹之间的温暖程度低、父亲与兄弟姐妹的时间差异以及父母感受到的不公平的区别对待。研究结果表明，早期兄弟姐妹关系对教育程度有长期影响，并为家庭在成就方面的作用提供了新的见解。
