摘　　要：将Simon任务与知觉负荷任务的视觉搜索范式相结合,通过比较高低负荷条件下Simon效应的大小,探讨Simon效应的产生是否与刺激鉴别阶段有关.实验一的刺激为颜色,实验二的刺激为字母.两个实验的结果均显示,高负荷条件和低负荷条件下的Simon效应差异并不显著,表明Simon效应的产生与刺激鉴别阶段的加工无关,同时也说明无关刺激位置的编码是自动激活的.To explore whether the generation of Simon effect is related to the stimulus-identification stage, Simon effect was examined in the visual search paradigm under high and low load conditions. The stimuli were colors in Experiment 1 and words in Experiment 2. The results of both experiments showed that the size of Simon effect in the high load condition was comparable to that in the low load condition, which im- plied that Simon effect did not originate from the the results also suggested that the encoding of the process of the stimulus-identification stage. In addition, irrelevant stimulus location was activated automatically.
