神经系统正常的人更倾向于与空间右侧的物体碰撞，而不是与空间左侧的物体碰撞。这种现象可以归因于伪忽视，其中个人选择性地关注左视野。目前的研究使用虚拟路线跟踪任务来调查这种影响，该任务集中呈现在较低的领域和较高的领域。他们还研究了惯用手性。52名参与者（其中4名是左撇子）完成了这项任务，当被呈现在较低的区域时，更多的左侧碰撞出现了。在上一种情况下，这种偏置与预期的向右偏置方向相反。在中心条件下，碰撞行为没有明显的方向偏差。用手性和展示条件之间的相互作用表明，在中心条件下，左撇子参与者经历了更多的右侧碰撞。总的来说，这些结果表明，碰撞行为中的方向偏差（即左与右）是由视野中的位置（中央、上方或下方）和惯用手来调节的。（植物学报，2009,15,225-230）
Abstract Neurologically normal people tend to collide with objects on the right side more frequently than with objects located on the left side of space. This phenomenon could be attributable to pseudoneglect wherein individuals selectively attend to the left field. The current study investigated this effect using a virtual route-following task that was presented centrally, in the lower field, and in the upper field. Handedness was also examined. Fifty-two participants (four left handed) completed this task, and when presented in the lower field, more left-side collisions emerged. In the upper condition, this bias reversed direction to the expected rightward bias. In the central condition, there was no significant directional bias in collision behavior. An interaction between handedness and presentation condition indicated that left-handed participants experienced more right-side collisions in the central condition. Collectively, these results suggest that directional biases (i.e., left vs. right) in collision behavior are modulated by both location in the visual field (central, upper, or lower) and handedness.
