Testing memory of a VR environment: comparison with the real environment and 2D pictures

In recent years, there has been a growing trend in cognitive psychology research towards recreating experimental situations in virtual reality (VR). VR settings are thought to have higher ecological validity than laboratory settings using digital, two-dimensional (2D) pictures. Some studies have shown cognitive performance in VR settings to follow that of the real world. However, other studies obtained controversial results. The present study tested the memory performance of three groups of participants who were exposed to the same environment (a room) through different modalities: in real life, in VR, and through 2D pictures. The results highlighted that participants who were exposed to the target room in real life had an overall better memory performance, compared to participants who saw the room in VR or through 2D pictures. On the other hand, no differences in memory performance emerged between the VR and 2D picture groups, except for the non-suggestive verbal task. The results suggest that future research should be careful in assuming that performance in VR settings is comparable to real life and that VR is more ecological than traditional 2D media.
