线索起点模糊水平和注视时间对汉字知觉干扰效应的影响

How Starting Point of Blurred Cues and Viewing Time Influence the Perception Interference Effect on Chinese Characters

采用经高斯模糊技术处理的汉字,以辨认为任务,实验一考察了线索起点模糊水平和注视时间、实验二考察了线索注视时间和刺激辨认时间对知觉干扰效应的影响。结果发现:1.线索起点模糊水平的增加对汉字知觉干扰效应存在显著的影响;2.超越激活水平的最低阈值之后,线索注视时间的延长(1、2、4、6秒)不再影响知觉干扰效应;3.刺激辨认时间的延长(2、4、6秒)对知觉干扰效应影响不大。这些结果都倾向于支持失匹配假说。

Using Gassian-blurred Chinese characters and naming tasks, the present research studied the perception interference effect in Chinese characters. Experiment 1 investigated the effects of the starting point of cueblurredness and viewing time of the cues, Experiment 2 investigated the effects of viewing time of prior cues and of the last presentation on the interference effect in Chinese character identification. The results were that 1. Increasing the starting point resulted in a larger magnitude of the perception interference effect; 2. once a threshold was passed, increasing viewing time of the prior cues （1,2,4,6 sec） would no longer affect the perceptual interference effect; 3. increasing identification time （2,4,6 sec） had no distinct effect on the perception interference effect. Results 2 and 3 were in contrast with what was found for pictures. The results showed that the viewing time effect previously found on pictures did not occur to Chinese characters. The results provided evidence for the Mismatch Explanation.
