The purpose of this study was to investigate the effects on prefrontal cortex brain activity when participants attempted to stop a car accurately at a stop line when driving at different speeds using functional near-infrared spectroscopy (fNIRS). Twenty healthy subjects with driving experience drove their own cars for a distance of 60 m five times each at their own pace or as fast as possible. The variation in the distance between the stop line and the car was not significantly different between the self-paced and high-speed tasks. However, oxygenated hemoglobin concentration in the prefrontal cortex was significantly higher in the high-speed task than in the self-paced task. These findings suggest that driving at high speed requires more divided attention than driving at self-paced speed, even though the participants were able to stop the car at the same distance from the target. This study shows the advantages and usefulness of fNIRS .
这项研究的目的是使用功能近红外光谱（fNIRS）研究参与者在以不同速度驾驶时试图将车准确停在停车线时对前额叶皮层大脑活动的影响。20 名具有驾驶经验的健康受试者以自己的节奏或尽可能快的速度五次驾驶自己的汽车行驶 60 米。自定速度和高速任务之间停车线和汽车之间的距离变化没有显着差异。然而，前额叶皮层的氧合血红蛋白浓度在高速任务中明显高于自定速度任务。这些发现表明，即使参与者能够将车停在离目标相同的距离，高速驾驶比自定速度驾驶需要更多的分散注意力。这项研究表明了 fNIRS 的优势和实用性。
