The reliability of estimations of working memory capacity has not been thoroughly examined. The present study examined the test-retest reliability for working memory capacity as estimated in a lateralized change detection task, which is frequently used in studies involving electroencephalography. The test-retest correlations between K values for each set size in the two tests varied from 0.502 to 0.757, with test-retest correlations rising as set size increased. The results indicate that individual visual working memory capacity can be reliably estimated in a change detection task. Furthermore, test-retest reliability was higher when the two tests occurred at the same time of day than at different times of day.

工作记忆容量估计的可靠性尚未得到彻底检验。本研究检验了在侧化变化检测任务中估计的工作记忆容量的测试-重测信度，该任务常用于涉及脑电图的研究中。在两次测试中，每个集合大小的 K 值之间的测试-重测相关性从 0.502 到 0.757 不等，随着集合大小的增加，测试-重测相关性也随之上升。结果表明，在变化检测任务中可以可靠地估计个体的视觉工作记忆容量。此外，当两次测试在同一天的不同时间进行时，测试-重测可靠性高于在不同时间进行时。
