很少有人知道的机制，记忆的关系是完成的，或有关的时间过程的关键过程。在这里，眼动测量被用来检查的时间过程中的主题的访问和使用的关系记忆。在四个实验中，参与者研究了叠加在风景背景上的面孔，并在先前观看的场景上叠加了三张面孔。与测试显示中的其他同样熟悉的面孔相比，参与者对最初与场景一起研究的面孔表现出不成比例的观看。当提供一个预览以前观看过的场景，允许有关的预期将被呈现的脸出现，不成比例的观看表现在500-750毫秒后，测试显示发作，超过一个完整的第二次提前明确的行为反应，甚至发生时，不需要公开的反应。在没有预览的情况下，观看效果延迟了大约1秒。海马损伤的健忘症患者的眼动行为中不存在关系记忆效应，这表明这些效应严重依赖于海马系统。结果提供了一个索引的记忆的脸场景的关系，表明检索和识别这些关系发生的时间，并建议检索和使用的关系记忆严重依赖于海马和强制性发生，无论响应要求。
Little is known about the mechanisms by which memory for relations is accomplished, or about the time Course of the critical processes. Here, eye movement measures Were used to examine the time course of subjects' access to and use of relational memory. In four experiments, participants Studied faces superimposed on scenic backgrounds and were tested with three-face displays superimposed on the scenes viewed earlier. Participants exhibited disproportion ate viewing of the face originally studied with the scene, compared to other equally familiar faces in the test display. When a preview of a previously viewed scene was provided, permitting expectancies about the to-be-presented face to emerge, disproportionate viewing was manifested within 500-750 msec after test display onset, more than a full second in advance of explicit behavioral responses, and occurred even when overt responses were not required. in the absence of preview, the viewing effects were delayed by approximately 1 sec. Relational memory effects were absent in the eye movement behavior of amnesic patients with hippocampal damage, suggesting that these effects depend critically on the hippocampal system. The results provide an index of memory for face-scene relations, indicate the time by which retrieval and identification of these relations occur, and suggest that retrieval and use of relational memory depends critically on the hippocampus and occurs obligatorily, regardless of response requirements.
