Within memory processing, feature and conjunction effects refer to higher false alarms (incorrectly naming items as previously seen) for stimuli with partial/all features taken from different previously studied versus novel items. In this study, we compared feature-conjunction effects in the memory tasks of both item recognition and source retrieval, using faces as stimuli. We found greater feature-conjunction effects on source retrieval versus item recognition tasks, though participants gave slower responses on source retrieval versus item recognition. Thus, our data were consistent with dual-process memory theory in which familiarity contributes to high false alarms in compound faces even while feature-conjunction effects enhance recollection in source retrieval.
在记忆加工过程中，特征效应和联合效应指的是，对于具有部分/所有特征取自不同先前学习项目而非新异项目的刺激，虚报率（将项目错误地命名为先前见过）更高。在本研究中，我们以面孔作为刺激，比较了项目识别和来源检索这两种记忆任务中的特征联合效应。我们发现，相较于项目识别任务，来源检索任务中的特征联合效应更大，尽管参与者在来源检索任务中的反应比项目识别任务中的反应更慢。因此，我们的数据与双加工记忆理论一致，即在复合面孔中，熟悉性导致了高虚报率，而特征联合效应则增强了来源检索中的回忆。
