Taking a motor planning perspective, this study investigates whether haptic force cues displayed on the steering wheel are more effective than visual cues in signaling the direction of an upcoming lane change. Licensed drivers drove in a fixed-base driving simulator equipped with an active steering system for realistic force feedback. They were instructed to make lane changes upon registering a directional cue. Cues were delivered according to the movement precuing technique employing a pair of precues and imperative cues which could be either visual, haptic, or crossmodal (a visual precue with a haptic imperative cue, and vice versa). The main dependent variable was response time. Additional analyses were conducted on steering wheel angle profiles and the rate of initial steering errors. Conditions with a haptic imperative cue produced considerably faster responses than conditions with a visual imperative cue, irrespective of the precue modality. Valid and invalid precues produced the typical gains and costs, with one exception. There appeared to be little cost in response time or initial steering errors associated with invalid cueing when both cues were haptic. The results are consistent with the hypothesis that imperative haptic cues facilitate action selection while visual stimuli require additional time-consuming cognitive processing.
从运动规划的角度来看，本研究调查了方向盘上显示的触觉力线索在指示即将到来的车道变换方向时是否比视觉线索更有效。持照驾驶员在配备主动转向系统以提供逼真力反馈的固定基座驾驶模拟器中驾驶。他们被指示在接收到方向线索时进行车道变换。线索根据运动预提示技术传递，该技术采用一对预提示和指令性线索，这些线索可以是视觉的、触觉的或跨模态的（视觉预提示与触觉指令性线索，反之亦然）。主要因变量是反应时间。对方向盘角度轮廓和初始转向误差率进行了额外分析。无论预提示模态如何，具有触觉指令性线索的条件比具有视觉指令性线索的条件产生的反应要快得多。有效和无效预提示产生了典型的收益和成本，但有一个例外。当两个线索都是触觉线索时，与无效提示相关的反应时间或初始转向误差似乎几乎没有成本。结果与以下假设一致，即指令性触觉线索有助于动作选择，而视觉刺激需要额外的耗时认知处理。
