Testing the Waters: Validating a Virtual Reality-based Neuropsychological Test

Published on September 14, 2022

Just imagine, taking a familiar test but with a virtual twist! In this study, researchers sought to bring the Rey Auditory Verbal Learning Test (RAVLT) into the virtual world. They created a virtual reality adaptation of the RAVLT called VR-RAVLT, where participants interacted with a virtual office secretary to complete the test. To ensure the validity of VR-RAVLT, they compared it to the original RAVLT. The results were impressive! The VR-RAVLT demonstrated similar capabilities in measuring cognitive abilities as the original test. This means that the virtual version accurately reflects real-life scenarios and can be just as reliable as the traditional format. With these promising findings, researchers are hopeful that VR-based neuropsychological tests like VR-RAVLT can be used in clinical settings for diagnosis and treatment. Dive into the full article to explore how this exciting technology is pushing the boundaries of cognitive testing!

ObjectiveTranslations and adaptations of traditional neuropsychological tests to virtual reality (VR) technology bear the potential to increase their ecological validity since the technology enables simulating everyday life conditions in a controlled manner. The current paper describes our translation of a commonly used neuropsychological test to VR, the Rey Auditory Verbal Learning Test (RAVLT). For this aim, we developed a VR adaptation of the RAVLT (VR-RAVLT) Which is based on a conversation with a secretary in a virtual office using a fully immersive VR system. To validate the VR-RAVLT, we tested its construct validity, its age-related discriminant validity and its test-retest validity in reference to the original gold standard RAVLT (GS-RAVLT).MethodSeventy-eight participants from different age groups performed the GS-RAVLT and the VR-RAVLT tests in a counterbalanced order in addition to other neuropsychological tests. Construct validity was validated using Pearson’s correlations coefficients and serial position effects; discriminant validity was validated using receiver operating characteristic area under the curve values and test-retest reliability was validated using intraclass correlation coefficients.ResultsComparing both RAVLTs’ format results indicates that the VR-RAVLT has comparable construct, discriminant and test–retest validities.Conclusionthe novel VR-RAVLT and the GS-RAVLT share similar psychometric properties suggesting that the two tests measure the same cognitive construct. This is an indication of the feasibility of adapting the RAVLT to the VR environment. Future developments will employ this approach for clinical diagnosis and treatment.
