年龄相关的变化会影响驾驶能力，包括驾驶的平稳性。这个操作需要使用非中心策略（基于世界中心表征）和自我中心策略（基于自我中心表征）；然而，随着年龄的增长，驾驶时更倾向于以自我为中心的策略。此外，驾驶能力和空间导航能力也会随着年龄的增长而下降。因此，我们评估了空间导航与驾驶平稳性之间的关系，并测试了驾驶模拟器是否可以用于评估老年驾驶员的平稳变道。方法选取34名健康老年驾驶员（平均年龄68.2 +/- 5.4岁）和20名年轻驾驶员（平均年龄20.2 +/- 5.4岁）作为研究对象。使用驾驶模拟器评估驾驶平稳性，使用放置卡片测试a /B评估空间导航。我们还使用标准的神经心理学测试评估了视觉感知和一般智力功能。结果老年驾驶员空间导航能力和驾驶平稳性明显低于年轻驾驶员。此外，我们发现在两组中，驾驶平稳性与空间导航之间存在负相关。这些结果表明，老年人空间导航能力的下降可能是驾驶平稳性下降的原因，并且空间导航能力和驾驶平稳性随年龄的增长而下降。综上所述，我们发现老年组的车辆运动平稳性与空间导航之间存在显著的相关性，青年组和老年组的车辆运动平稳性之间存在显著的相关性。从驾驶模拟器中获得的平顺度值确实在自我/异心认知中显示出一些证据，这些证据可能会随着年龄的变化而变化。驾驶模拟器可以帮助开发干预程序或评估措施的驾驶员功能下降。
Background Age-related changes affect driving ability, including the smoothness of driving. This operation requires the use of both allocentric strategies (based on world-centered representations) and egocentric strategies (based on self-centered representations); however, with age, a greater preference for egocentric strategies is evident when driving. Furthermore, an age-related decline occurs in both driving ability and spatial navigation. We therefore assessed the relationship between spatial navigation and driving smoothness and tested whether a driving simulator can be used to evaluate smooth lane changes in older drivers. Methods A total of 34 healthy older drivers (mean age: 68.2 +/- 5.4 years old) and 20 younger drivers (mean age = 20.2 +/- 5.4 years old) participated in this study. The smoothness of driving was assessed using a driving simulator and spatial navigation was assessed using the Card-Placing Test-A/B. We also assessed visual perception and general intellectual function using standard neuropsychological tests. Results Older drivers had significantly worse spatial navigation and exhibited less smooth driving than younger drivers. Furthermore, we found a negative correlation between the smoothness of driving and spatial navigation within both groups. These results suggest that the deterioration in spatial navigation in older people may underlie the observed decrease in driving smoothness, and that spatial navigation and smooth driving deteriorate with age. Conclusions Considering these results, we found a significant correlation in the older group between the smoothness of vehicle movement and spatial navigation, in the smoothness of vehicle movement between the young and old groups. The smoothness values, which indices thoroughly derived from the driving simulator are indeed showing some evidence in ego/allocentric cognitions, which may change by age. The driving simulator could aid the development of intervention programs or assessment measures for drivers with a decreased function.
