我们可以根据物品的运动类型来搜索它们吗？我们在这里考虑基于三种类型的运动的视觉搜索：（i）弹道运动，其中对象在直线上移动，直到它们遇到显示边界;（ii）随机行走运动，其中对象随机改变方向;（iii）复合运动，其中对象围绕通常的弹道轨迹随机波动移动。搜索效率的不对称模式可以通过假设视觉注意是由对线性运动和运动变化敏感的过程引导来解释。结果并没有显示出一个更复杂的能力，分离项目的基础上，他们的运动的性质。
Can we search for items based on their type of motion? We consider here visual search based on three types of motion: (i) ballistic motion, in which objects move in a straight line until they encounter a display boundary; (ii) random-walk motion, in which objects change direction randomly; (iii) composite motion, in which objects move with random fluctuations around a generally ballistic trajectory. The asymmetric pattern of search efficiency can be explained by assuming that visual attention is guided by processes sensitive to the presence of linear motion and change in motion. The results do not reveal a more sophisticated ability to segregate items based on the nature of their motion.
