摘要
利用眼动(Eyelink-2000)自带软件EB编制实验程序呈现由字母"T"经旋转后组成的刺激材料,参照预搜索范式设计了"预览组"和"清屏组"两组实验,利用区组内评估法评估两组实验预览效应产生与否以及产生的程度,以此来考察预览效应产生的内在机制。实验结果显示不管靶子是否出现,预览组和清屏组产生预览效应的程度一致,这表明:预览效应的产生是被试基于自上而下对旧客体的抑制而引起的。
Experiment Builder was used to present the stimulus which composed by "T" and after rotated by" T". Designed two experi- ments "preview group" and "Clear screen group" to study why preview effect occurred. Evaluate the degree of preview effect with the assessment method of within - group. The results show that the same degree of preview effect occurred in two group of experiments. So we got the conclusion that preview effect occurred because of human' s top - down inhibition to old items.
