主题关系对无线索回忆再认效应的影响

本研究采用RWCR范式,从无线索回忆再认的视角考察了主题关系对熟悉性的影响。结果发现,主题关系能够引发无线索回忆再认效应。具体表现为,在回忆错误项目中,被试对与学过项目有主题关系线索的熟悉性评分显著高于与学过项目无主题关系线索的熟悉性评分。这一结果表明,个体在信息提取失败时,概念形式的语义信息也能引发基于熟悉性的再认判断。

The Influence of Thematic Relation on Recognition Without Cued-recall Effect

Recognition without cued recall(RWCR)is the phenomenon that participants can effectively discriminate cues that resemble studied items from the ones that do not,even when they are not able to recall a studied item which is cued at test.Though previous researches identified some perceptual information could produce familiarity in the absence of recall,it is still inconclusive whether semantic features could give rise to the RWCR effect.In the present study,we used the RWCR paradigm to investigate whether the “pure” semantic feature could lead to familiarity in the absence of recall by using thematic relation which minimizes the overlap of perceptual information.The results revealed that recognition without cued recall for thematic relation still occurred.These results demonstrate that familiarity-based recognition judgments could be based on the semantic information,which could provide converging evidence for the feature-matching explanations for recognition without cued recall.
