Recent neurophysiological studies have indicated that there are two parallel pathways in vision processing independently shape and motion. There are many methods for examining perception of color and shape, but none for examining visual motion perception. In this study, we devised a "motion discrimination task (MDT)" for evaluating motion perception, which was displayed on a computer monitor, and recorded normal responses to the MDT in 90 normal subjects. Responses to MDT were not affected by visual acuity, but were affected by dot speed of the MDT. There was little trial-to-trial or subject variability in the MDT. These findings indicate that our MDT is a good clinical test for evaluating motion perception in human subjects.
最近的神经生理学研究表明，在视觉处理中存在两条独立处理形状和运动的平行通路。有许多方法可用于检查颜色和形状感知，但没有用于检查视觉运动感知的方法。在本研究中，我们设计了一种用于评估运动感知的“运动辨别任务（MDT）”，该任务显示在计算机显示器上，并记录了90名正常受试者对MDT的正常反应。对MDT的反应不受视力影响，但受MDT点速度的影响。MDT中试验间或受试者间的变异性很小。这些发现表明，我们的MDT是评估人类受试者运动感知的良好临床测试。
