摘要
伪忽视(pseudoneglect)是指正常人在水平线段等分的空间注意测验中出现的轻微左偏的现象,本研究探索伪忽视现象在驾驶行为中的视觉表现。研究首先验证伪忽视是否存在,其次验证实车研究中驾驶员在真实道路条件下的驾驶眼动行为,最后采用驾驶员在模拟驾驶舱中的眼动数据探索其模式。研究分成三个实验,历时两年时间完成全部的数据收集和分析。主要的研究结果是,实验一,采用经典的伪忽视研究范式,线段对切任务判断,同时记录被试的注视点、注视时长和左右眼瞳孔大小数据。结果发现,被试存在对左侧视野注视更多的倾向。实验二采用实车驾驶研究,研究样本人数是5人。要求驾驶员在城市快速路、高速公路和二级公路(县道)三种不同道路驾驶,探索其驾驶过程中眼动规律。结果发现,对于城市快速路和高速路而言,左侧注意显著多于右侧,而对于二级公路则是右侧显著多于左侧;同时,城市快速路和高速路单位注视点和单位注视时长显著高于二级公路。另外,城市快速路和二级公路左眼瞳孔在左侧区域显著大于右侧,二级公路瞳孔直径显著大于城市快速路大于高速公路。高速公路的水平视角更大,尤其是对左侧区域;二级公路的垂直视角更大,尤其是对上方视野。实验三是模拟驾驶眼动实验,研究要求熟练驾驶员和非熟练驾驶员在模拟驾驶器上完成与实验二中二级公路完全相同路段的驾驶任务。结果表明,此时熟练与非熟练驾驶员均存在对左侧的多注意,路况与垂直深度是影响注视区域的重要因素。熟练驾驶员具有更大的注意广度研究总结论:驾驶伪忽视现象随着道路路况和驾驶经验的不同而出现不同的表现形式。
‘‘Pseudoneglect'' is "healthy subjects tend to exhibit a subtle bias of visual attention favoring left space. The study is to explore the visual performances of pseudoneglect in and the traffic-driving field, which covers three experiments. The first experiment was to test the existence of pseudoneglect, the second experiment studied the driving visual movement in the real driving situation and the last experiment was to explore the eye movement model in the simulation driving, The major results were as follows. The first experiment was applied the classical research paradigm and eye movement track tool. The result was found the existence of visual left bias. The second experiment was to recruit five drivers in the real driving case study. The real vehicle-driving test as the second experiment explored the drivers' visual movement model by requiring them driving in urban expressways, highways and secondary roads(County Road). The last experiment was to compare the professional drivers and novice drivers in terms of visual movement when driving in the simulator. The results were found that both types of drivers tended to more left visual bias and professional drivers show larger attentional span and more vertical depth than novice driver. As the result, in urban expressways and highways, the left side of the road was significantly attended more than the right part;but for the secondary roads was just the opposite. Meanwhile, the drivers' unit fixation and the unit time during fixation of the urban expressways and highways were significantly more than that of in the secondary roads. In addition, for the pupil diameter, drivers had significantly bigger size in the secondary roads than in the urban expressways and in the highways. The left eye's pupil diameter when focusing the left side was significantly larger than the right side in the urban expressways and the secondary roads. Driving in the highways had greater horizontal viewing angle, especially for the left area; driving in the secondary roads had larger vertical viewing angle, especially above the horizon. In conclusion, the phenomenon of traffic pseudoneglect has diverse manifestations in the different conditions of driving situation. Meanwhile, the attention left bias was found in the subtle bias in driving as well as in the line bisection task.
