Virtual reality-based neuropsychological assessments proffer the potential to address the limited ecological validity of pen-and-paper measures of memory. To investigate the construct validity of a newly developed virtual reality measure of memory, the Virtual Environment Grocery Store (VEGS), traditional neuropsychological measures of memory and executive functioning were administered to 48 older adults and 55 young adults. Performances on the VEGS memory tasks and the traditional neuropsychological assessments of memory were positively correlated, indicating that memory for VEGS content was similar to memory for traditional paper-and-pencil measures. The older adults performed significantly worse than young adults on the VEGS and the California Verbal Learning Test, but the DKEFS Color-Word Interference failed to differentiate the groups. Furthermore, significant differences were found between groups for the VEGS memory and multitasking measures. The VEGS has the advantage over traditional measures of providing objective measurement of individual components of memory in simulations of everyday activities.
基于虚拟现实的神经心理学评估提供了一种可能，可以解决纸笔记忆测量方法中生态有效性有限的问题。为了研究一种新开发的基于虚拟现实的记忆测量方法——虚拟环境杂货店（VEGS）的结构效度，对 48 名老年人和 55 名年轻人进行了传统的记忆和执行功能神经心理学测试。VEGS 记忆任务的表现与传统神经心理学的记忆评估呈正相关，这表明对 VEGS 内容的记忆与对传统纸笔测试的记忆相似。老年人在 VEGS 和加利福尼亚语言学习测试中的表现明显逊于年轻人，但 DKEFS 颜色-单词干扰未能区分两组。此外，在 VEGS 记忆和多任务测试方面，组间存在显著差异。与传统的记忆测试相比，VEGS 的优势在于能够在日常活动的模拟中对记忆的各个成分进行客观的测量。
