它示出，游标敏锐度几乎是成比例的线长度（在5-20弧分的范围内），提供的目标的方向是随机的，从审判到审判，并提供没有间隙中断线。一对间隙（每个Vernier条中有一个间隙）的影响得出的结论是，在对形状和方向线索进行视觉分析之前，线终止将目标分割成独立的部分，而形状和方向线索仅在此类特征之间进行评估。
It is shown that Vernier acuity is nearly proportional to line length (in the range 5-20 arc min), provided that the orientation of the target is randomized from trial to trial and provided that no gap interrupts the line. The effect of a pair of gaps, one in each of the Vernier bars leads to the conclusion that line terminations dissect the target into independent parts prior to the visual analysis of shape and orientation cues, which are only assessed between such features.
