Children labeled as underachievers are compared to a matched group functioning normally within the classroom. Factor analyses of the data from several tests reveal that the "normal" children not only have achieved higher academic performance but also have better learning aptitude. The inference may be made that many "underachievers" actually have a low general aptitude when carefully measured.
被贴上学习成绩不佳标签的儿童与在课堂上表现正常的匹配组儿童进行比较。对来自多项测试的数据进行因素分析后发现，“正常”儿童不仅取得了更高的学业成绩，而且具有更好的学习能力倾向。由此可以推断，许多“学习成绩不佳者”在经过仔细测量后，实际上总体能力倾向较低。
