A number of theories of hippocampal function have placed spatial context at the center of richly recollected memories, but the subjective and objective ways that spatial context underlies the recollection of single words has been largely overlooked and underexplained. In this study, we conducted three experiments to investigate the involvement of spatial context in the recollection of single words. In all three experiments, participants encoded single words with varying features such as location and color. The subjective experience of recollection was measured using remember/know judgments and participant self‐report of the types of information they recollected about the words. Objectively, recollection was measured using source memory judgments for both spatial and non‐spatial features associated with the words. Our results provide evidence that spatial context frequently accompanies the recollection of single, isolated words, reviving discussions on the role of the hippocampus in spatial and detailed recollection.

空间上下文和图像对单个单词的回忆的贡献。

许多海马功能理论将空间上下文置于丰富回忆的中心，但空间上下文作为单个单词回忆的基础的主观和客观方式在很大程度上被忽视和解释不足。在这项研究中，我们进行了三个实验来调查空间上下文在单个单词的回忆中的参与。在所有三个实验中，参与者编码具有不同特征（例如位置和颜色）的单个单词。回忆的主观体验是使用记住/知道判断和参与者对他们回忆的关于单词的信息类型的自我报告来衡量的。客观地，使用源记忆判断来测量与单词相关的空间和非空间特征的回忆。
