在环境中安全移动需要我们监控周围的移动物体或人员。然而,识别场景中的运动物体是复杂的自我运动,这增加了整个视网膜的运动。为了识别与世界相关的物体运动,大脑必须“补偿”或“解析”由于自我运动而引起的视网膜运动的成分。我们以前已经证明,视网膜线索所产生的中央视觉有助于解决这个问题。在这里,我们调查周边视觉的贡献,通常认为提供强大的线索,自我运动。固定的参与者观看了一个大的视野显示器,径向流模式呈现在外围,并判断了中心探头的轨迹。在两个实验中,我们展示和量化的贡献,周边的光流流解析在向前和向后移动。
Safe movement through the environment requires us to monitor our surroundings for moving objects or people. However, identification of moving objects in the scene is complicated by self-movement, which adds motion across the retina. To identify world-relative object movement, the brain thus has to ‘compensate for’ or ‘parse out’ the components of retinal motion that are due to self-movement. We have previously demonstrated that retinal cues arising from central vision contribute to solving this problem. Here, we investigate the contribution of peripheral vision, commonly thought to provide strong cues to self-movement. Stationary participants viewed a large field of view display, with radial flow patterns presented in the periphery, and judged the trajectory of a centrally presented probe. Across two experiments, we demonstrate and quantify the contribution of peripheral optic flow to flow parsing during forward and backward movement.
