Abstract

Objectives: As individuals age, cognitive abilities such as working memory (WM), decline. In the current study, we investigated the effect of age on WM, and elucidated sources of errors.

Method: A total of 102 healthy individuals, aged 18 to 71, participated in this research. We designed and administered a face-based visual WM task, collecting responses via a graded scale in a delayed match-to-sample reproduction task.

Results: The error of participants increased significantly as they aged. Our analysis revealed a significant age-related rise in the standard deviation of error distribution. However, there was no significant change in uniform probability with age.

Conclusion: We found that WM performance declines through the lifespan. Investigating the sources of error, we found that the precision of WM decreased monotonously with age. The results also indicated that the probability of guessing the response as a measure of random response is not affected by age.

衰老会降低视觉工作记忆的准确性。

目的：随着个体年龄的增长，工作记忆（WM）等认知能力下降。在目前的研究中，我们调查了年龄对WM的影响，并阐明了误差的来源。方法：共有102名年龄在18岁至71岁之间的健康人参与了这项研究。我们设计并实施了一个基于人脸的视觉WM任务，在延迟匹配样本复制任务中通过分级量表收集反应。结果：随着年龄的增长，参与者的误差显著增加。我们的分析显示，误差分布的标准偏差随年龄的增长而显著增加。然而，随着年龄的增长，一致概率没有显著变化。结论：我们发现WM的表现会随着寿命的延长而下降。通过对误差来源的调查，我们发现WM的精度随着年龄的增长而单调下降。结果还表明，猜测反应作为随机反应的衡量标准的概率不受年龄的影响。

期刊介绍： The purposes of Aging, Neuropsychology, and Cognition are to (a) publish research on both the normal and dysfunctional aspects of cognitive development in adulthood and aging, and (b) promote the integration of theories, methods, and research findings between the fields of cognitive gerontology and neuropsychology. The primary emphasis of the journal is to publish original empirical research. Occasionally, theoretical or methodological papers, critical reviews of a content area, or theoretically relevant case studies will also be published.
