It has been suggested that virtual reality may provide a medium for producing neuropsychological measures with greater ecological validity. The present study examined the usefulness of virtual reality (VR) to assess learning and memory in individuals with traumatic brain injury (TBI). A total of 20 TBI participants were compared with 20 healthy controls on their ability to learn and recall 16 target items presented within a VR-based generic office environment. The results indicated that VR memory testing accurately distinguished the TBI group from controls. Additionally, non-memory-impaired TBI participants acquired targets at the same rate as HC participants. Finally, there was a significant relationship between the VR Office and a standard neuropsychological measure of memory, suggesting the construct validity of the task. These findings suggest that the VR Office provides a viable medium for measuring learning and memory. The present results provide preliminary support for the ecological validity of the VR Office, which ultimately can improve assessment of real-world functioning following TBI.
有人提出,虚拟现实可能为产生具有更高生态效度的神经心理学测量方法提供一种媒介。本研究考察了虚拟现实(VR)在评估创伤性脑损伤(TBI)个体的学习和记忆方面的效用。总共20名TBI参与者与20名健康对照者在学习和回忆呈现于基于VR的通用办公环境中的16个目标项目的能力方面进行了比较。结果表明,VR记忆测试能准确区分TBI组和对照组。此外,非记忆受损的TBI参与者获取目标的速度与健康对照者相同。最后,VR办公环境与标准的记忆神经心理学测量方法之间存在显著关系,表明该任务具有结构效度。这些发现表明,VR办公环境为测量学习和记忆提供了一种可行的媒介。目前的结果为VR办公环境的生态效度提供了初步支持,这最终可以改善对TBI后现实世界功能的评估。
