abstract = {Although most research on navigation in aging focuses on
allocentric processing deficits, impaired strategy switching
may also contribute to navigational decline. Using a
specifically designed task involving navigating a town-like
virtual environment, we assessed the ability of young and
old participants to switch from following learned routes to
finding novel shortcuts. We found large age differences in
the length of routes taken during testing and in use of
shortcuts, as, while nearly all young participants switched
from the egocentric route-following strategy to the
allocentric wayfinding strategy, none of the older
participants stably switched. Although secondary tasks
confirmed that older participants were impaired both at
strategy switching and allocentric processing, the
difficulty in using shortcuts was selectively related to
impaired strategy switching. This may in turn relate to
dysfunction of the prefrontal-noradrenergic network
responsible for coordinating switching behavior. We conclude
that the large age difference in performance at the
shortcutting task demonstrates for the first time, how
strategy switching deficits can have a severe impact on
navigation in aging.},
