Orientation-dependent spatial memories for scenes viewed on mobile devices

Abstract

We examined whether spatial representations for scenes experienced on the screens of mobile devices are orientation dependent and whether the type of movement (physical vs. simulated) during learning affects the encoding and the retrieval of spatial information. Participants studied a spatial layout depicted on a tablet and then carried out perspective-taking trials in which they localized objects from imagined perspectives. Depending on condition, participants either rotated the tablet along with their body or remained stationary and swiped with their finger on the screen to change their viewpoint within the scene. Results showed that participants were faster and more accurate to point to objects from an imagined perspective that was aligned than misaligned to their initial physical orientation during learning, suggesting that they had formed an orientation-dependent representation. Although no differences were found between movement conditions during pointing, participants were faster to encode spatial information with physical than simulated movement.

Are Spatial Memories for Familiar Environments Orientation Dependent?

“…Even in studies in which participants are allowed to move in order to study the array from any viewpoint, the starting orientation (i.e., the first viewpoint from which the layout is experienced) is still found to influence performance. That is, when no salient environmental cues are present and no instructions are given to memorize the layout from a different perspective, the first viewpoint is associated with the best performance, leading researchers to conclude that it was used as the reference orientation for representing information in memory (e.g., Avraam, Hatzipanayioti, & Avraamides, 2020). In the present study, we manipulated the starting orientation by having participants in the unfamiliar condition study the room in VR starting from one of the four orientations that were aligned with the geometric structure.…”
