A new arXiv preprint examines the Trail Making Test, a classic neuropsychological assessment, when delivered through immersive virtual reality. The authors note that moving such a test into VR changes how the test operates, so it cannot be assumed that scores carry the same meaning as in the original format.
The paper's central point is that before VR-based scores are interpreted, the people the test is meant for should find it usable, acceptable, and comfortable to experience. The study specifically looks at younger and older adults, two groups that may differ in familiarity with and reaction to VR.
Because only one source was provided, there are no contrasting findings to compare. The preprint's argument is a caution: usability and acceptability are prerequisites for interpreting VR neuropsychological test results, not optional extras.
