Motion integration is anisotropic during smooth pursuit eye movements

Four movies showing of how motion coherence depends on the direction of smooth pursuit eye movements. We used a multiple-aperture array, with drift speeds being attributed to correspond to (100% coherence) to a single global motion direction or randomly to some proportion.Participant's task is to track the black dot and discriminate between upward or downward motion of the surrounding. All movies show global motion that is a slightly downward from horizontal. The elements are low contrast(necessary for motion to cohere) and therefore may only be visible in full screen mode or close to the screen.Movie 1: Global motion (50% coherent) opposite to the motion of the pursuit target (black dot) Movie 2: Global motion (100% coherent) opposite to the motion of the pursuit target (black dot) Movie 3: Global motion (50% coherent) in the direction of the pursuit target (black dot) Movie 4: Global motion (100% coherent) in the direction of the the pursuit target (black dot)

本数据集包含四部展示运动一致性如何依赖于平滑追踪眼动方向的影片。本研究采用了多孔径阵列，其中漂移速度被分配以对应（100%一致性）于单一全局运动方向，或随机分配至某一比例。受试者的任务是追踪黑色圆点，并区分周围环境的向上或向下运动。所有影片均显示全局运动略低于水平方向。元素对比度较低（对于运动的一致性而言是必要的），因此仅在全屏模式或靠近屏幕时方可清晰可见。影片1：全局运动（50%一致性）与追踪目标（黑色圆点）的运动方向相反；影片2：全局运动（100%一致性）与追踪目标（黑色圆点）的运动方向相反；影片3：全局运动（50%一致性）与追踪目标（黑色圆点）的运动方向相同；影片4：全局运动（100%一致性）与追踪目标（黑色圆点）的运动方向相同。
