Kindergarten, third-grade and fifth-grade children were tested on a same-different auditory discrimination task. Stimuli consisted of familiar and unfamiliar 3-letter words which were subdivided into high and low positional frequency word pairs. Analysis of correct same and different judgments supported the hypothesis that prereaders who have had normal language experiences develop sensitivities to intraword-redundancy relations. Children made significantly more correct same or different judgments when word pairs were high rather than low in summed positional frequency.
幼儿园、三年级和五年级的儿童接受了一项相同-不同听觉辨别任务的测试。刺激物由熟悉和不熟悉的三个字母的单词组成，这些单词被细分为高和低位置频率的单词对。对正确的相同和不同判断的分析支持了这样一种假设，即有正常语言经历的学前儿童会对单词内冗余关系产生敏感性。当单词对的总位置频率较高而不是较低时，儿童做出的相同或不同判断的正确率显著更高。
