abstract = {Efficient spatial navigation requires not only accurate
spatial knowledge but also the selection of appropriate
strategies. Using a novel paradigm that allowed us to
distinguish between beacon, associative cue, and place
strategies, we investigated the effects of cognitive aging
on the selection and adoption of navigation strategies in
humans. Participants were required to rejoin a previously
learned route encountered from an unfamiliar direction.
Successful performance required the use of an allocentric
place strategy, which was increasingly observed in young
participants over six experimental sessions. In contrast,
older participants, who were able to recall the route when
approaching intersections from the same direction as during
encoding, failed to use the correct place strategy when
approaching intersections from novel directions. Instead,
they continuously used a beacon strategy and showed no
evidence of changing their behavior across the six sessions.
Given that this bias was already apparent in the first
experimental session, the inability to adopt the correct
place strategy is not related to an inability to switch from
a firmly established response strategy to an allocentric
place strategy. Rather, and in line with previous research,
age-related deficits in allocentric processing result in
shifts in preferred navigation strategies and an overall
bias for response strategies. The specific preference for a
beacon strategy is discussed in the context of a possible
dissociation between beacon-based and associative-cue-based
response learning in the striatum, with the latter being
more sensitive to age-related changes.},
