This investigation sought to understand whether performance in naturalistic virtual reality tasks for cognitive assessment relates to the cognitive domains that are supposed to be measured. The Shoe Closet Test (SCT) was developed based on a simple visual search task involving attention skills, in which participants have to match each pair of shoes with the colors of the compartments in a virtual shoe closet. The interaction within the virtual environment was made using the Microsoft Kinect. The measures consisted of concurrent paper-and-pencil neurocognitive tests for global cognitive functioning, executive functions, attention, psychomotor ability, and the outcomes of the SCT. The results showed that the SCT correlated with global cognitive performance as measured with the Montreal Cognitive Assessment (MoCA). The SCT explained one third of the total variance of this test and revealed good sensitivity and specificity in discriminating scores below one standard deviation in this screening tool. These findings suggest that performance of such functional tasks involves a broad range of cognitive processes that are associated with global cognitive functioning and that may be difficult to isolate through paper-and-pencil neurocognitive tests.
本研究旨在了解认知评估的自然主义虚拟现实任务表现是否与预期测量的认知领域相关。鞋橱测试（SCT）基于一项涉及注意力技能的简单视觉搜索任务开发，参与者必须将每双鞋子与虚拟鞋橱中隔层的颜色相匹配。虚拟环境中的交互使用微软Kinect进行。测量包括用于整体认知功能、执行功能、注意力、心理运动能力的同步纸笔神经认知测试以及SCT的结果。结果表明，SCT与用蒙特利尔认知评估（MoCA）测量的整体认知表现相关。SCT解释了该测试总方差的三分之一，并在该筛查工具中辨别低于一个标准差的分数时显示出良好的敏感性和特异性。这些发现表明，此类功能任务的表现涉及与整体认知功能相关的广泛认知过程，并且可能难以通过纸笔神经认知测试进行分离。
