This study aims to further our understanding of spatial cognition in order to progress the field and assist in the assessment and diagnostics of associated deficits in affected populations. Research has outlined the practicality of VR in assessing cognitive complaints. VR can provide ecological validity to navigation assessments and can be used alongside neuropsychological tools to further understand cognitive deficits. Therefore, the objectives of this study were to investigate the relationships of presence and subjective navigation ability with objective navigation performance in VR, and to further examine the effect of gender on navigation performance. The van der Ham et al. (2020) online task battery was used to assess spatial navigation ability by requiring participants to complete five tasks testing landmark, location and path knowledge. The experiment was conducted online on a computer or phone screen. Sense of presence in the virtual environment and subjective navigation ability were measured using the IPQ (Schubert, Friedmann, and Regenbrecht, 2001) and the WQ (Claessen et al., 2016). A test-retest design was employed to investigate the gender differences in performance over time. The results of this study indicate that presence is not a significant predictor of navigation performance in the VR task. However, subjective navigation ability did predict objective navigation performance. Additionally, gender differences were found in performance over time, with males consistently performing better than females. These findings suggest a need to further investigate the different navigation mechanisms used by males and females, and the effect that stereotypical beliefs have on performance. In conclusion, this study determined that assessment of navigation abilities is not affected by experienced presence, and thus can be made accessible in an online format. The findings for gender differences and the relationship between subjective navigation ability and objective navigation performance also have the potential to contribute evidence-based improvements in assessments, diagnostics and rehabilitation interventions. Further research is required to investigate the effect of different levels of immersion on sense of presence and performance as this could affect VR assessment of navigation.Show less
