For a sample of college observers, visual performance was assessed with three types of measures: (1) contrast sensitivity for a range of spatial frequency gratings with 4-Hz flicker, (2) contrast sensitivity for a range of stationary wallchart gratings, and (3) dynamic visual acuity (DVA) for a range of target velocities. Within each of these three performance measures, mean results were generally consistent with previous reports. However, across-test comparisons revealed little commonality of processes between either of the contrast sensitivity scores and the dynamic acuity scores. These findings are discussed in terms of the separate contributions to overall visual performance made by the increasingly popular contrast sensitivity function (CSF) and DVA.
对于一组大学生观察者，通过三种测量方法评估视觉表现：(1) 对一系列带有4赫兹闪烁的空间频率光栅的对比敏感度，(2) 对一系列静止壁图光栅的对比敏感度，以及(3) 对一系列目标速度的动态视敏度（DVA）。在这三种表现测量中的每一种内，平均结果总体上与先前的报告一致。然而，跨测试比较显示，对比敏感度分数和动态视敏度分数之间的过程几乎没有共同之处。根据日益流行的对比敏感度函数（CSF）和DVA对整体视觉表现的不同贡献来讨论这些发现。
