abstract = {Updating navigational memories is important for everyday
tasks. It was recently found that older adults are impaired
in updating spatial representations in small, bi-dimensional
layouts. Because performance in small-scale areas cannot
predict navigational behavior, we investigated how aging
affects the updating of navigational memories encoded in
large, 3-dimensional environments. Moreover, since locations
can be encoded relative to the observer (egocentric
encoding) or relative to landmarks (allocentric encoding),
we tested whether the presumed age-related spatial updating
deficit depends on the available spatial cues. By combining
whole-body motion tracking with immersive virtual reality,
we could dissociate egocentric and allocentric spatial cues
and assess navigational memory under ecologically valid
conditions (i.e., providing body-based and visual cues). In
the task, objects were relocated overnight, and young and
older participants had to navigate to the updated locations
of the objects. In addition to replicating age-related
deficits in allocentric memory, we found age-related
impairments in updating navigational memories following
egocentric encoding. Finally, older participants depicted
stronger representations of the previous navigational
context that were correlated with their spatial updating
deficits. Given that these effects may stem from inefficient
suppression of former navigational memories, our findings
propose a mechanism that helps explain the navigational
decline in aging.},
