知觉或记忆条件下对连续变化刺激的相似判断

Similarity Judgment of Continuous Changing Stimuli under the Perceptual or Memory Model

控制不同材料(图形和字母)的大小、位置和长宽比连续变化,在标准和待判断刺激同时(知觉任务)或相继呈现(记忆任务)两种条件下进行相似判断的实验研究。结论为(1)任务方式对图形的相似判断有非常显著的影响;(2)知觉任务中相似判断的反应时非常显著地长于记忆任务中的反应时;(3)对材料各种特征的相似判断和加工速度差异非常显著,某些特征在相似表征中有较重要的作用。

With the conditioning of perceptual or memory models, the experiment tested the similarity judgment and RT of different continuous changing dimensions and kinds of stimuli. The conclusions are as follows: firstly, under the conditions of perceptual or memory experiments the similarity judgment of stimulants varied, depending on the dimension of stimulants. Secondly, responding under perceptual or memory models significantly affected both representation choosing and RT. Thirdly, the sort of stimuli significantly affected RT, but not similarity representations.
