注意力跟踪目标的最大速度是通过三种类型的（径向）运动显示来测量的：仅注意力跟踪产生方向印象的模糊运动、表观运动和连续运动。跟踪的上限（大约 50 deg s−1）比某些刺激可以感知运动的最大速度低一个数量级。在除一种情况外的所有情况下，最终极限似乎是时间频率之一，4-8 Hz，而不是视网膜速度或旋转速率。有人认为，这个速率反映了注意力的时间分辨率，即可以将事件与之前或之后的事件区分开来的最大速率。在一种情况下，还发现了注意力跟踪速度限制的证据，即注意力沿着显示器周围路径移动的最大速率。
The maximum speed for attentive tracking of targets was measured in three types of (radial) motion displays: ambiguous motion where only attentive tracking produced an impression of direction, apparent motion, and continuous motion. The upper limit for tracking (about 50 deg s−1) was an order of magnitude lower than the maximum speed at which motion can be perceived for some of these stimuli. In all cases but one, the ultimate limit appeared to be one of temporal frequency, 4–8 Hz, not retinal speed or rotation rate. It was argued that this rate reflects the temporal resolution of attention, the maximum rate at which events can be individuated from those that precede or follow them. In one condition, evidence was also found for a speed limit to attentive tracking, a maximum rate at which attention could follow a path around the display.
