摘要
本研究用汉字材料及反应时的数据来探讨重复知盲现象及有关机制。在实验一中，被试必须判断快速连续呈现的两个字究竟是否包含两个或是只有一个动物字。结果显示在７０毫秒时，有重复知盲现象（重复动物字组比非重复动物字组的反应时为长）；在１００毫秒时则无；另外，在２００毫秒时则有重复启动现象产生（重复动物字组比非重复动物字组的反应时为短）。实验二采用同样的材料及呈现方法。
Two experiments were carried out to explore repetition blindness and related mechanisms. In Experiment 1 , subjects were asked to judge whether or not two rapidly and sequentially presented Chinese characters involved one or two animal characters. When the display rate was 70ms per item, longer response times were found in the repeated-character condition relative to the unrepeated condition, whereasa reversed pattem was found whem the display rate was 200ms per item .The same procedure and materials were adopted in Expedient 2 with a fixed display rate (i. e., 70ms per item). The task was to decide whether or not the second character in each sequence represented an animal . The repetition blindness pattem was not found, but a repetition priming trend was shown. The results collectively indicate that both display duration and task are important determinants of repetition blindness. Implications of the present methodology and results on the processing of repeatedly presented stimuli are also discussed.
