The authors conducted 3 sets of experiments. In the 1st set of experiments, participants made alphabetic position estimations. In the 2nd set, participants made interletter distance estimations. In the 3rd set, they made comparative judgments of the alphabetic order of a pair of letters. The results showed that participants had highly accurate ordinal level information about the alphabet in memory but that interval level information was systematically distorted. In addition, alphabetic serial information was found to be used in 2 distinct modes in memory, depending on whether the representation could be contained within the span of immediate memory.
作者进行了三组实验。在第一组实验中，参与者进行字母位置估计。在第二组实验中，参与者进行字母间距离估计。在第三组实验中，他们对一对字母的字母顺序进行比较判断。结果表明，参与者在记忆中拥有关于字母表的高度准确的顺序水平信息，但区间水平信息存在系统性扭曲。此外，发现字母序列信息在记忆中以两种不同模式被使用，这取决于该表征是否能够包含在即时记忆的跨度内。
