Long-Term Retention of Spatial Knowledge Acquired in Virtual Reality

Abstract

Retention of spatial knowledge was compared after acquisition using virtual reality (VR), a map, and a real building. Participants were trained to navigate a route and to note the locations of landmarks. Two weeks later they were tested on their ability to navigate the route and to point to the landmarks they had learned. They were tested in either an aligned or contra-aligned orientation. The orientation specificity for VR observed immediately after training in our previous experiment (Clawson, Miller, Knott, & Sebrechts, 1998) was magnified after retention. On the route test, the VR group performed better than the map group, but only when tested in the aligned orientation. On the survey test, the VR group was less accurate than the map or real building groups, especially in the contra-aligned condition. Potential cognitive and perceptual causes of this orientation specificity are discussed.
