米勒1956年的经典文章以讨论短期记忆中的容量限制而闻名，但文章的大部分内容涉及绝对判断任务中的容量限制以及这种限制与信息论的关系。米勒最先提出的许多关于绝对判断的谜题，今天仍然是一个谜题。作者回顾了一些针对这一问题的文献，并讨论了几个试图解释这一现象的模型。自1956年以来，为了了解短时记忆的机制和局限性，人们进行了大量的研究工作，取得了相当大的进展。作者简要讨论了其中的一些进展。作者和米勒一样，通过指出在这两个调查领域中观察到的限制之间可能缺乏联系来得出结论。
Miller's classic 1956 article is best known today for its discussion of capacity limitations in shortterm memory, but the bulk of the article dealt with capacity limitations in absolute judgment tasks and the relation of such limitations to information theory. Many of the puzzles ob absolute judgment first raised by Miller remain a puzzle today. The authors review some of the literature directed toward this issue and discuss a few models that attempt to elucidate the phenomena. Since 1956 there has been an enormous research effort aimed at understanding the mechanisms and limitations of shortterm memory, resulting in considerable progress. The authors briefly discuss some of these advances. The authors conclude, as Miller did, by noting the probable lack of connection between the limitations observed in these 2 areas of inquiry.
