Retrieval of a subset of studied items and the presentation of those items as retrieval cues typically impair retrieval of the other items. Previous research on this self-limiting property of memory retrieval has relied heavily on short retention intervals and similar context between encoding and test. Here, we examined retrieval dynamics also after a prolonged retention interval with different spatial and social context between encoding and test, conditions that mimic people’s remembering in many situations of daily life. For both unrelated word lists and more integrated prose material, we found retrieval and cuing to impair recall of other studied items after a short retention interval, but to improve recall in the prolonged retention interval condition. The results demonstrate that retrieval dynamics depend critically on situation, indicating that quite often in daily life, retrieval may be a self-propagating, rather than a self-limiting process. 相似文献

采用部分线索效应经典范式与情绪Stroop任务相结合的范式,采取更为敏感的指标,对部分线索效应的认知抑制进程进行了考察,同时为提取抑制假说提供证据。结果发现,部分线索呈现后进行情绪Stroop任务,部分线索组反应时显著短于自由回忆组,提取结束后进行情绪Stroop任务,部分线索组和自由回忆组反应时差异不显著,提取未完成时,部分线索组反应时显著短于自由回忆组。结果提示,在以情绪词为实验材料的部分线索效应中,抑制在部分线索呈现之后即发生,提取未完成时,抑制持续存在,研究结果支持提取抑制假说,同时也对提取抑制假说做了一定补充,即抑制的持续时间受随后是否有提取任务调节。 相似文献

Three experiments assess the veracity of the strategy disruption explanation of part-list cuing impairment. Experiment 1 demonstrated no mnemonic detriment in recall as a result of significant disruption of the participants' self-selected forward associative seriation retrieval strategy. Experiment 2 replicated Experiment 1 while reducing overall performance levels in an attempt to reveal any possible detrimental effects. Experiment 3 ruled out 2 possible alternative explanations by demonstrating the typical part-list cuing impairment within this experimental context. It is concluded that the results challenge a strict version of the strategy disruption hypothesis. 相似文献

What are the cognitive processes underlying people's decisions from memory? Previous research suggests that these processes can be best described by strategies that are based on abstract knowledge about the decision task (e.g., cue–criterion relations). However, recent results show that different cue presentation formats trigger the use of different decision strategies and that exemplar‐based strategies can account for memory‐based decisions as well. In three experiments, this effect was replicated, and mediation analyses identified the quality of the underlying knowledge representation as the critical variable that determines decision behavior. This supports the view that exemplar‐based reasoning is used as a backup system if cue abstraction is hindered. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

探讨了6岁儿童的类别学习能力、类别表征和分类策略。62名儿童参加了实验,实验1采用了"5/4模型"类别结构,实验2采用了"3/3类别结构"。结果发现:6岁儿童已经具备了一定的类别学习能力;相对于原型表征,6岁儿童更倾向于进行样例表征;6岁儿童在注意上具有定位在高典型性特征维度上的能力,但不具备定位在区分性特征维度上的能力;在类别学习策略上主要采用单维度分类策略和规则加例外的分类策略。 相似文献
