Short-latency ocular following responses in monkeys, induced by first- and second-order motion during a fixation task, were sensitive to stimulus size, retinal eccentricity and motion duration. Latency of eye movements was no different for first- or second-order motion and simply marked the occurrence of movement in the visual field. Second-order motion produced higher velocity eye movements than did first-order motion. The velocity of eye movements was influenced by the orientation of second-order pattern components as well as their conspicuous energy. Even when partially suppressed by a fixation task, involuntary eye movements during the initial pursuit remain sensitive to several properties of visual motion.
在固定任务期间，由一阶和二阶运动诱发的猴子短潜伏期眼球跟踪反应，对刺激大小、视网膜离心率和运动持续时间敏感。一阶或二阶运动的眼球运动潜伏期没有差异，仅仅标志着视野中运动的发生。二阶运动比一阶运动产生更高速度的眼球运动。眼球运动的速度受二阶模式成分的方向及其显著能量的影响。即使在固定任务部分抑制的情况下，初始追踪期间的非自主眼球运动对视觉运动的几个属性仍然敏感。
