Abstract

Time has an immense influence on our memory. Truncated encoding leads to memory for only the ‘gist’ of an image, and long delays before recall result in generalized memories with few details. Here, we used crowdsourced scoring of hundreds of drawings made from memory after variable encoding (Experiment 1) and retentions of that memory (Experiment 2) to quantify what features of memory content change across time. We found that whereas some features of memory are highly dependent on time, such as the proportion of objects recalled from a scene and false recall for objects not in the original image, spatial memory was highly accurate and relatively independent of time. We also found that we could predict which objects were recalled across time based on the location, meaning, and saliency of the objects. The differential impact of time on object and spatial memory supports a separation of these memory systems.
绘画揭示了物体记忆的变化,但不包括空间记忆的变化。
时间对我们的记忆有着巨大的影响。截断编码会导致我们只能记住图像的 "要点",而长时间的延迟则会导致我们的记忆过于笼统,缺乏细节。在这里,我们通过对数百幅经过可变编码(实验 1)和记忆保持(实验 2)后的记忆图画进行众包评分,来量化记忆内容的哪些特征会随着时间的推移而发生变化。我们发现,记忆的某些特征高度依赖于时间,例如从场景中回忆起的物体比例以及对原始图像中没有的物体的错误回忆,而空间记忆则高度准确,且相对独立于时间。我们还发现,我们可以根据物体的位置、含义和显著性来预测哪些物体在不同时间段会被回忆起来。时间对物体记忆和空间记忆的不同影响支持了这两种记忆系统的分离。

期刊介绍: Cognition is an international journal that publishes theoretical and experimental papers on the study of the mind. It covers a wide variety of subjects concerning all the different aspects of cognition, ranging from biological and experimental studies to formal analysis. Contributions from the fields of psychology, neuroscience, linguistics, computer science, mathematics, ethology and philosophy are welcome in this journal provided that they have some bearing on the functioning of the mind. In addition, the journal serves as a forum for discussion of social and political aspects of cognitive science.
