摘要
伪忽视是健康个体存在轻微偏左的不对称空间注意。影响这个现象的因素主要包括刺激材料、年龄、认知负荷和知觉负荷等。其中，眼动搜索习惯曾经被认为是伪忽视现象的主要因素，甚至提出伪忽视是眼动偏好现象。但是，最近丈献研究普遍认为，伪忽视不是眼动行为，而是注意特质。近10年的大脑神经层面的证据发现，右脑腹侧注意网络对左侧空间注意偏好有较大的贡献，而且在神经传导束的证据中也发现右脑大纵束二型对左侧空间注意的激活程度高于其他两种类型的传导束。另外，注意偏好的时间分辨率研究发现，注意的左侧空间偏向发生在注意发生后的100～200ms之内，眼动搜索时间则是在1500ms之内出现最大左偏。该现象的应用研究主要体现在交通驾驶员的注意能力和驾驶视觉搜索模式的关系研究。研究意义在于为安全交通提供两条原则，首先，道路交通驾驶环境设置要满足驾驶员的注意特质的需求：其次，通过合理干预，可以抑制视觉搜索习惯，培养安全的驾驶搜索模式。
Pseudoneglect is ＂healthy subjects tend to exhibit a subtle bias of visual attention favouring left space＂. There are many factors that affect pseudoneglect, such as stimulus, age, cognitive load and perceptual load. Among them, eye movement habit has been coded as the major factor to the explanation of pseudoneglect. However, recent neural studies exhibited that right hemisphere VAN contributed to pseudonegelct more than left hemisphere. The right hemisphere SLF Ⅱ corresponded to greater deviation to the left-hemi field than the other two SLF did. Moreover, pseudoneglect is occurred at time of 100-200 ms after stimulus displayed. While the duration time of visual searching is 1500 millisecond reaching to the greater left deviation. The application of current study is applied in the traffic driving to explore the relationship between drivers＇ attention trait and driving visual search. The results indicated that two principles of safety transportation might be recognized. First, the safety driving setting should be consistent with the drivers attention trait. Second, it is necessary to cultivate safety driving visual search model by the mean of inhibiting visual search habit through the theoretical visual intervention.
