ABSTRACT

Objectives

The current research addressed gaps in the literature regarding short-term computerized cognitive retest performance in young and older adults using two integrated speed-accuracy metrics. The aims were: (a) to advance the aging literature on short-term retest performance using a computerized cognitive battery and a retest schedule that included both within- and between-day time points, and (b) to assess the test-retest reliability of two integrated speed-accuracy metrics, inverse efficiency scores (IES) and balanced integration scores (BIS).

Method

Twenty young (18–23 years) and thirty older (65–71 years) men completed a battery measuring a range of cognitive functions, six times over three testing days, each 1 week apart.

Result

Compared to young adults, older adults exhibited steeper within- and between-day performance gains in IES and BIS, which may reflect a combination of lower initial cognitive ability and familiarity, indicating that older adults may require more familiarization on computerized tests. Relative to unadjusted reaction times, IES reliability appeared comparable in older adults, but slightly lower among young adults. The reliability of BIS was lower than unadjusted reaction times and IES in both age groups.

Discussion

Our findings provide guidance for researchers wanting to combine speed and accuracy into a single performance metric in repeated testing contexts.

年轻人与老年人的短期复试表现：综合速度准确度测量的考虑

摘要

目标

目前的研究解决了文献中关于年轻人和老年人使用两个综合速度准确度指标的短期计算机化认知重新测试表现的空白。目的是：（a）使用计算机化的认知电池和包括日内和日间时间点的复试时间表来推进关于短期复试表现的老化文献，以及（b）评估复试的可靠性两个综合速度准确度指标，逆效率得分（IES）和平衡综合得分（BIS）。

方法

20 名年轻（​​18-23 岁）和 30 名年长（65-71 岁）男性完成了一系列认知功能的电池测量，在三个测试日内进行了六次测试，每次间隔 1 周。

结果

与年轻人相比，老年人在 IES 和 BIS 中表现出更陡峭的日内和日间表现提升，这可能反映了较低的初始认知能力和熟悉度的结合，表明老年人可能需要更多地熟悉计算机测试。相对于未调整的反应时间，IES 可靠性在老年人中表现出可比性，但在年轻人中略低。在两个年龄组中，BIS 的可靠性均低于未调整的反应时间和 IES。

讨论

我们的研究结果为希望在重复测试环境中将速度和准确性结合为单一性能指标的研究人员提供了指导。
