An experiment was performed to examine the effects of the size of target and noise letters on selective identification of a target letter. Twelve undergraduate students were required to identify a target letter on a visual display which presents a target letter alone or a target letter flanked by two noise letters. The reaction time of pressing buttons to the target letter was measured under combined conditions of size of target and noise letters. The large target letter was identified faster than the small one whether it was accompanied by noise letters or not. The large noise letters exerted stronger effects on the identification of a target letter than the small one. The results agreed with the prediction based on the assertion by Eriksen and Schultz (1979). Further, it was found that the effects of size of letters varied according to the relation between target letters and noise letters and to the similarity of a target letter to noise letters.
进行了一项实验，以检验目标字母和干扰字母的大小对目标字母选择性识别的影响。要求12名本科生在视觉显示器上识别一个目标字母，该显示器上单独呈现一个目标字母，或者一个目标字母两侧伴有两个干扰字母。在目标字母和干扰字母大小的组合条件下，测量按下按钮识别目标字母的反应时间。无论是否伴有干扰字母，大的目标字母都比小的目标字母识别得更快。大的干扰字母对目标字母识别的影响比小的干扰字母更强。结果与基于埃里克森和舒尔茨（1979年）的论断所做的预测一致。此外，还发现字母大小的影响会根据目标字母与干扰字母之间的关系以及目标字母与干扰字母的相似性而有所不同。
