“…Patterns of error led the authors to conclude that performance was governed by an online, constantly updated, egocentric representation of the environment. These results were also interpreted as providing evidence against enduring spatial representations (Wang & Spelke, 2000; but see Waller & Hodgson, 2006). Alternatively, Mou et al (2004) had participants update a layout of either 9 or 10 objects (separate experiments) and make judgments of relative direction (e.g., imagine being at the banana, facing the wood, point to the pan).…”

Four experiments required participants to keep track of the locations of (i.e., update) 1, 2, 3, 4, 6, 8, 10, or 15 target objects after rotating. Across all conditions, updating was unaffected by set size. Although some traditional set size effects (i.e., a linear increase of latency with memory load) were observed under some conditions, these effects were independent of the updating process. Patterns of data and participant strategies were inconsistent with the common view of spatial updating as an online process. Instead, the authors concluded that participants formed enduring, long-term memory representations of the layouts at learning that were used to reconstruct spatial information about the layouts as needed (i.e., offline updating). These results support M. Amorim, S. Glasauer, K. Corpinot, and A. Berthoz's (1997) 2-system model of spatial updating that includes both online and offline updating.

“…[73,77]). While we highlighted the established notion that there are a variety of egocentric coding schemes in §5b, our primary concern here is to argue for the utility of egocentric coding for spatial representation in natural tasks rather than to determine which of the possible ego centres is at the heart of this coding scheme.…”

One of the paradoxes of vision is that the world as it appears to us and the image on the retina at any moment are not much like each other. The visual world seems to be extensive and continuous across time. However, the manner in which we sample the visual environment is neither extensive nor continuous. How does the brain reconcile these differences? Here, we consider existing evidence from both static and dynamic viewing paradigms together with the logical requirements of any representational scheme that would be able to support active behaviour. While static scene viewing paradigms favour extensive, but perhaps abstracted, memory representations, dynamic settings suggest sparser and task-selective representation. We suggest that in dynamic settings where movement within extended environments is required to complete a task, the combination of visual input, egocentric and allocentric representations work together to allow efficient behaviour. The egocentric model serves as a coding scheme in which actions can be planned, but also offers a potential means of providing the perceptual stability that we experience.

“…In Experiment 1, participants were tested in the learning environment, so it was possible that the knowledge of the immediate real environment may have influenced updating of the retrieved map-acquired environment (Waller & Hodgson, 2006). In Experiment 2, after learning the map, the blindfolded participants were escorted to a novel testing room.…”

“…Most current theories of spatial cognition agree on the dichotomy of an online spatial-updating system and an offline spatial memory system (Avraamides & Kelly, 2008;Burgess, 2006;Mou, Fan, McNamara, & Owen, 2008;Sholl, 2001;Waller & Hodgson, 2006;Wang & Spelke, 2002). In most circumstances, the spatial-updating system keeps track of the individual's immediate real environment (online spatial representation) but not remote and/or imagined environments (offline spatial memories).…”

Spatial updating of map-acquired representation

In the present study, we examined whether people can update a map-acquired spatial representation. The participants learned a spatial layout from a map displayed on a computer screen, and then performed spatial judgments at a novel position either in the same room (Exp. 1) or in a distal room (Exp. 2). They were required to imagine the spatial layout from a perspective aligned with the learning direction, aligned with their facing direction during testing, or toward a novel direction misaligned with the two directions mentioned above. In both the immediate and nonimmediate environments, the participants performed better from the learning direction than from the novel direction, and also performed better from the facing direction than from the novel direction. These results reveal that people establish an orientationspecific spatial representation through map learning, and that they can update a map-acquired representation during locomotion.
