According to the associative network of memory representations proposed by embedded processes models, the links between related memory representations were automatically established, which rendered these representations more easily activated. The present study adopted color recall tasks to explore whether the memory performance of identical objects was enhanced the strengthening links between them, producing facilitating effect of identical objects. In Experiment 1, the number of identical items was manipulated. The results evidenced the facilitating effect, which was positively related to the number of identical objects. Experiment 2 modulated the spatial location of identical objects, which suggested that the facilitating effect was absent when two pairs of identical objects were located diagonally. Furthermore, Experiment 3 suggested that the facilitating effect was observed for the identical items which were presented in the second and fourth quadrants, rather than the first and third quadrants. Together, these results evidenced the facilitating effect of identical objects, which, however, was affected by spatial bias.
根据嵌入式过程模型提出的记忆表征关联网络，相关记忆表征之间的联系会自动建立，这使得这些表征更容易被激活。本研究采用颜色回忆任务来探究相同物体之间联系的加强是否会增强其记忆表现，从而产生相同物体的促进效应。在实验1中，对相同物品的数量进行了操控。结果证明了促进效应的存在，且该效应与相同物体的数量呈正相关。实验2对相同物体的空间位置进行了调节，结果表明当两对相同物体呈对角线放置时，促进效应不存在。此外，实验3表明，在第二和第四象限呈现的相同物品会观察到促进效应，而在第一和第三象限则没有。总之，这些结果证明了相同物体的促进效应，然而，该效应受到空间偏差的影响。
