Our purpose was to explore the effect of navigation instruction on older drivers' driving performance at left turn intersections. Left turns at intersections are particularly complex because they require many perceptive and cognitive abilities under considerable time pressure.
Fifty-four participants were recruited: 18 drivers with early-stage Alzheimer's disease (AD), 18 neurologically healthy older drivers and 18 younger individuals. Various cognitive processes were measured, and 9 left turn maneuvers with or without navigation instruction were evaluated during an in-traffic road test. The psychomotor, planning and decision-making components involved in left turn were also analyzed closely.
Only older drivers (both healthy drivers and those with AD) were negatively affected by navigation instruction during the maneuver. The planning and decision-making components were more likely to be affected by the navigation instruction.
This finding highlights the importance of carefully considering the use of navigation instructions when developing navigation systems. Adapting this instruction is necessary to simplify our understanding of the real-world driving environment and to avoid increasing the cognitive load of older drivers.
我们的目的是探讨导航指令对老年驾驶员在左转弯路口驾驶性能的影响。路口左转弯特别复杂，因为在相当大的时间压力下，它需要许多感知和认知能力。
招募了54名参与者：18名患有早期阿尔茨海默病（AD）的驾驶员、18名神经系统健康的老年驾驶员和18名年轻人。测量了各种认知过程，并在实际道路测试中评估了9次有或没有导航指令的左转弯操作。还密切分析了左转弯过程中涉及的心理运动、规划和决策成分。
在操作过程中，只有老年驾驶员（包括健康驾驶员和患有AD的驾驶员）受到导航指令的负面影响。规划和决策成分更容易受到导航指令的影响。
这一发现凸显了在开发导航系统时仔细考虑导航指令使用的重要性。调整此指令对于简化我们对现实世界驾驶环境的理解以及避免增加老年驾驶员的认知负荷是必要的。
