Scoping Review of Virtual Environments for Assessing Episodic Memory

Abstract

To assess cognitive deficits in everyday tasks, clinical neuropsychologists have started to move toward neuropsychological testing performed in immersive virtual environments. Ideally, this type of assessment can provide greater ecological validity along with sufficient experimental control for accurate assessment. This paper presents a scoping review of studies using virtual assessment of episodic memory, a cognitive ability with a high level of clinical utility in differentiating neurological disorders. Gaps are identified and the implications of these gaps explored, especially about environmental locations and modes of interaction. Future study is suggested as to better understand and mitigate the effects of these issues on clinical practice.
