To determine the nature of effects of a preceding letter stimulus upon the recognition of a following letter stimulus, 20 subjects were sequentially and tachistoscopically presented pairs of letters of pairs of random patterns, which consist of the same number of elements, and asked to judge whether they were "same" or "different" in form. Four variable interstimulus intervals (ISI) between the 1st stimuli and the 2nd stimuli were employed as parameters. Results obtained were as follows: (a) percentages of correct responses for the letters were not significantly different from those for the random patterns, and (b) percentages of correct responses for the "same" matching tasks were significantly higher than those for the "different" matching tasks, but, differences in number of correct responses between the two tasks diminished as ISI increased. These results reveal structural, rather than naming, effects of preceding letters in the information processing of matching single letters.
为了确定先前字母刺激对后续字母刺激识别的影响性质，对20名受试者依次进行速示呈现由相同数量元素组成的成对随机图案字母对，并要求他们判断其形状是“相同”还是“不同”。将第一个刺激和第二个刺激之间的四个可变刺激间隔（ISI）用作参数。得到的结果如下：（a）字母的正确反应百分比与随机图案的正确反应百分比没有显著差异，并且（b）“相同”匹配任务的正确反应百分比显著高于“不同”匹配任务的正确反应百分比，但是，随着ISI增加，两项任务之间的正确反应数量差异减小。这些结果揭示了在前字母在单个字母匹配信息处理中的结构而非命名效应。
