Geometric cues, reference frames, and the equivalence of experienced-aligned and novel-aligned views in human spatial memory

摘要: Spatial memories are often organized around reference frames, and environmental shape provides a salient cue to frame selection. To date, however, the cues responsible for influencing selection remain relatively unknown. connect research on with that orientation via shape, we explored extent which geometric were incidentally encoded represented in memory by evaluating their influence Using virtual environment equipped head-mounted-display, presented participants to-be-remembered object arrays. We manipulated whether experienced viewpoint was aligned or misaligned global (i.e., principal axis of space) local wall orientations) cues. During subsequent judgments relative direction imagined standing at one object, facing second pointed toward third object), show performance best when imagining perspectives these cues; moreover, sufficient selection, capable exerting differential from experienced-imagined equivalent novel-imagined These results explicitly theory regarding spatial indicate fundamental properties space.
