虽然人们通常认为情景联想的记忆需要回忆，但有人认为，当刺激作为一个单位被体验时，熟悉过程可能有助于随后的联想识别。本研究考察了情景编码中的联想关系和知觉域对联想信息提取的影响。在研究过程中，参与者编码复合词和非复合词对，呈现给相同的感觉方式（视觉呈现）或不同的感觉方式（视听呈现）。在测试中，他们区分旧的，重新排列的和新的对，同时记录事件相关电位（ERP）。在早期的ERP组件，通常与熟悉的过程中，相关的差异联想记忆只出现化合物，无论其编码方式。与此相反，在后来的ERP组件与回忆，差异相关的联想记忆出现在所有的编码条件。这些研究结果可能表明，情节检索复合词可以支持熟悉相关的过程，无论这两个词是相同的或不同的感觉方式。
Although it is often assumed that memory of episodic associations requires recollection, it has been suggested that when stimuli are experienced as a unit, familiarity processes might contribute to their subsequent associative recognition. We investigated the effects of associative relations and perceptual domain during episodic encoding on retrieval of associative information. During study, participants encoded compound and non-compound words-pairs, presented either to the same sensory modality (visual presentation) or to different sensory modalities (audio-visual presentation). At test, they discriminated between old, rearranged, and new pairs while event related potentials (ERPs) were recorded. In an early ERP component, generally associated with familiarity processes, differences related to associative memory only emerged for compounds, regardless their encoding modality. In contrast, in a later ERP component associated with recollection, differences related to associative memory emerged in all encoding conditions. These findings may indicate that episodic retrieval of compound words can be supported by familiarity-related processes, regardless of whether both words were presented to the same or different sensory modalities.
