编码方式和线索显著性对前瞻记忆的影响

Effects of Encoding Strategies and the Salience of Cues on Prospective Memory

采用2(编码方式:口头复述,书写)×2(线索显著性:显著,非显著)的混合实验设计,探究不同编码方式和线索显著性对前瞻记忆的影响。结果发现:不同线索条件下反应时的主效应显著,不论是口头复述还是书写编码,对显著线索的反应时快于非显著线索;不同线索条件下正确率的主效应显著,对显著线索的正确率高于非显著线索;显著性条件下编码方式正确率的主效应显著,书写的正确率高于口头复述。这些结果说明显著条件对前瞻记忆具有促进作用,书写和口头复述两种编码方式的作用只在线索显著时存在差异。

The mixed experimental design of 2 （encoding strategies： verhal rephrase, writing） x2 （the salience of cues： salient cue, non-salient cue） was used to explore the influence of diffeient encoding strategies and the salience of cues on prospective memory. It was found that the main effect of the salience of cues are significant. Whether it was verhal rephrasing or writing encoding strategy, the response to salient cues was faster than non-salient cues; the main effects of the salience of cues on accuracy are significant, and the correct rate of salient cues is higher than non-salient cues; The main effects of accuracy of encoding strategies are significant under salient condition, and the accuracy of writing is higher than verhal rephrase. These results indicate that the salient condition has a promo- ting effect on prospective memory, and the effects of the two encoding strategies of writing and verbal rephrase are different from each other when the cues are salient.
