This study investigated whether and how visual representations of individual objects are bound in memory to scene context. Participants viewed a series of naturalistic scenes, and memory for the visual form of a target object in each scene was examined in a 2-alternative forced-choice test, with the distractor object either a different object token or the target object rotated in depth. In Experiments 1 and 2, object memory performance was more accurate when the test object alternatives were displayed within the original scene than when they were displayed in isolation, demonstrating object-to-scene binding. Experiment 3 tested the hypothesis that episodic scene representations are formed through the binding of object representations to scene locations. Consistent with this hypothesis, memory performance was more accurate when the test alternatives were displayed within the scene at the same position originally occupied by the target than when they were displayed at a different position.
本研究调查了单个物体的视觉表征在记忆中是否以及如何与场景背景相绑定。参与者观看了一系列自然主义场景，并在二选一的强制选择测试中检查了每个场景中目标物体的视觉形式记忆，干扰物体要么是不同的物体实例，要么是在深度上旋转的目标物体。在实验1和实验2中，当测试物体选项在原始场景中显示时，物体记忆表现比单独显示时更准确，这证明了物体与场景的绑定。实验3检验了情景场景表征是通过物体表征与场景位置的绑定而形成的这一假设。与该假设一致的是，当测试选项在场景中原本由目标物体占据的相同位置显示时，记忆表现比在不同位置显示时更准确。
