Spatial navigation strategies change in aging. Whereas younger adults use more shortcuts (place-based strategies), older adults use more familiar routes (response-based strategies). Does this bias in older adults reflect a preference for familiar routes or deficits in the ability to take shortcuts? We tested this question by providing an instructions-based intervention in which participants were told to take shortcuts rather than follow a learned route. We predicted that when instructed to do so, participants would increase shortcut taking overall, but older adults to a lesser extent than younger adults, supporting the notion that preference, rather than an inability to use place-based strategies, underlies the predilection for response-based strategies in older age. Younger ( = 64) and older ( = 65) adults completed two sessions of a desktop virtual navigation strategy task in which they could navigate to goal locations following a familiar route or taking a novel shortcut. In the first session, all participants received the instruction to navigate to goal locations. In the second session, half received the same instruction as before and the other half was instructed to take shortcuts. We computed participants' tendency toward place- or response-based strategies in each session. We replicated the finding that younger adults took more shortcuts when instructed; however, counter to our prediction, the instruction manipulation had no effect in older adults. These findings suggest that navigation strategy in younger adults is flexible and may reflect preference, whereas older adults more rigidly adhere to familiar routes, implying impaired or degraded survey knowledge.

空间导航策略在衰老过程中会发生变化。年轻人更多地使用捷径(基于地点的策略),而老年人则更多地使用熟悉的路线(基于反应的策略)。老年人的这种偏向是反映了对熟悉路线的偏好,还是走捷径能力的缺陷呢?我们通过提供一种基于指令的干预来测试这个问题,即告诉参与者走捷径而不是遵循已学的路线。我们预测,当被指示这样做时,参与者总体上会增加走捷径的次数,但老年人增加的程度小于年轻人,这支持了这样一种观点,即偏好而非无法使用基于地点的策略是老年人偏好基于反应的策略的基础。年轻成年人(n = 64)和年长成年人(n = 65)完成了两阶段的桌面虚拟导航策略任务,在该任务中他们可以沿着熟悉的路线或走新的捷径前往目标位置。在第一阶段,所有参与者都收到前往目标位置的指示。在第二阶段,一半参与者收到与之前相同的指示,另一半则被指示走捷径。我们计算了每个阶段参与者采用基于地点或基于反应的策略的倾向。我们重复了这样一个发现,即年轻成年人在得到指示时会走更多捷径;然而,与我们的预测相反,指令操作对年长成年人没有影响。这些发现表明,年轻成年人的导航策略是灵活的,可能反映了偏好,而年长成年人则更严格地坚持熟悉的路线,这意味着他们的勘测知识受损或退化。(《心理学文摘数据库记录》(c)2025美国心理学会,保留所有权利)
