On a winding open road, a driver consistently looks to the inside of each bend before turning the steering wheel. When researchers disrupt this coordination by instructing drivers not to move their eyes, drivers' performance is impaired and their completion time during racing increases. The present authors examined whether changing internal states in a way that also restricts eye movements reduces coordination and affects performance. Participants (N = 24) completed a simulated rally stage under manipulation of their anxiety state through ego threat. Performance decreased under pressure, and the decrement was associated with a narrowing of the range of eye movements and a reduced correlation of eye movements with steering. The authors discuss the possibility that the deterioration in performance is a cost of maintaining steering when eye-movement driving input to the steering controller is reduced.
在一条蜿蜒的开阔道路上，一名驾驶员在转动方向盘之前总是看向每个弯道的内侧。当研究人员通过指示驾驶员不要移动眼睛来打乱这种协调时，驾驶员的表现会受到损害，并且他们在比赛中的完成时间会增加。本文作者研究了以限制眼球运动的方式改变内部状态是否会降低协调性并影响表现。参与者（N = 24）在通过自我威胁操纵其焦虑状态的情况下完成了一个模拟拉力赛阶段。在压力下表现下降，这种下降与眼球运动范围变窄以及眼球运动与转向的相关性降低有关。作者讨论了这样一种可能性，即当输入到转向控制器的眼球运动驾驶信息减少时，表现的恶化是维持转向的一种代价。
