The current study showed that visual fixation of obstacles is not required for rapid and adaptive navigation of obstacles. Children and adults wore a wireless, head-mounted eye-tracker during a visual search task in a room cluttered with obstacles. They spontaneously walked, jumped, and ran through the room, stepping up, down, and over obstacles. Both children and adults navigated adaptively without fixating obstacles, however, adults fixated less often than children. We discuss several possibilities for why obstacle navigation may shift from foveal to peripheral control over development.
当前的研究表明,在对障碍物进行快速且适应性的导航时,无需对障碍物进行视觉注视。儿童和成人在一个布满障碍物的房间里进行视觉搜索任务时,佩戴了无线头戴式眼动仪。他们自发地在房间里行走、跳跃和奔跑,上下跨越障碍物。儿童和成人在不注视障碍物的情况下都能进行适应性导航,然而,成人注视障碍物的频率低于儿童。我们讨论了在发育过程中,障碍物导航为何可能从中央凹控制转变为外周控制的几种可能性。
