中文摘要：
采用线索范式，以汉语双字词为材料，探讨了不同工作记忆负荷条件下知觉负载、线索位置对视觉选择性注意的影响。结果表明：（1）线索位置影响被试对目标的加工，前线索条件下被试对目标的加工更为精细；（2）知觉负载对选择性注意的影响受到工作记忆的调节。高工作记忆负荷条件下，高知觉负载条件下的反应时显著短于低知觉负载条件；而在低工作记忆负荷条件下，不同知觉负载条件下的反应时差异不显著。
英文摘要：
With the cueing paradigm, two-character Chinese words with their frequency and strokes controlled were used as the materials. The perceptual load and cue location were manipulated under different working memory load conditions to find out how perceptual load, cue location and working memory load influenced the processing of task-related information. The results of Experiment 1 showed that in the high working memory load condition, both perceptual load and cue location influenced target processing. The results of Experiment 2 indicated that in the low working memory load condition, cue location influenced target processing, but perceptual load had little influence. These findings suggest that the cue location effect is independent. However, perceptual load has different influence on the target in different working memory load conditions, and its effects are modulated by working memory load.
