摘　　要：知觉干扰效应是更残缺刺激的呈现使部分残缺的同一刺激的识别发生困难.实验利用标准条件下识别正确率和递进条件下识别正确率的比值,详细考察在不同终止水平下知觉干扰效应量的变化趋势.研究发现:①模糊汉字在水平4、水平5和水平6三种终止水平下均存在极其显著的知觉干扰效应;②终止水平明显改善了模糊汉字的识别正确率,但产生的干扰效应量无显著差异.The perceptual interference effect refers to the phenomenon that a degraded version of a previously exposed stimulus is less likely to be identified if it is preceded by even more degraded versions.By means of the accurate ratio of standard condition performance to ascending condition performance,the experiment examined the change trend of the magnitude of the effect at different stopping points.The results showed that a highly significant interference effect was observed in degraded Chinese characters with a stopping point at level 4,5 or 6,and that the stopping point significantly improved the identification accuracy,with no significant difference in interference effect between the stopping points.
