Memory for objects and their location is a cornerstone of adequate cognitive functioning across the lifespan. Considering that human visual perception depends on the position of stimuli within the visual field, we posit that the position of objects in the environment may be a determinant aspect of mnemonic performance. In this study, a population of 25 young and 20 older adults completed a source-monitoring task with objects presented in the upper or lower visual field. Using standard Pr and multinomial processing tree analyses, we revealed that although familiarity-based item memory remained intact in older age, spatial memory was impaired for objects presented in the upper visual field. Spatial memory in aging is conditioned by the vertical position of information. These findings raise questions about the view that age-related spatial mnemonic deficits are attributable to associative dysfunctions and suggest that they could also originate from the altered encoding of object attributes.
对物体及其位置的记忆是整个生命周期中认知功能正常的基石。鉴于人类视觉感知取决于刺激在视野中的位置，我们假定环境中物体的位置可能是记忆表现的一个决定性因素。在本研究中，25名年轻人和20名老年人完成了一项源监测任务，其中物体呈现在上视野或下视野。使用标准的Pr和多项式加工树分析，我们发现，尽管基于熟悉度的项目记忆在老年时保持完好，但上视野中呈现的物体的空间记忆受损。衰老过程中的空间记忆受信息垂直位置的制约。这些发现对与年龄相关的空间记忆缺陷归因于联想功能障碍的观点提出了质疑，并表明它们也可能源于物体属性编码方式的改变。
