A measure of the temporal resolution of the visual system is the detection of temporal order of the onset of adjacent visual stimuli. The threshold is a few milliseconds and its variation with stimulus separation suggests the existence of a limited processing zone. Measurements were obtained of this distance function in the fovea and retinal periphery of two observers. Temporal order detection threshold does not vary greatly with retinal position out to 20 deg eccentricity, nor does the distance function change much in width, except near the fovea. An independent estimate of the zone for this kind of processing was obtained by testing the range within which signals from oppositely-directed stimulus pairs cancel. Thresholds for dichoptic stimuli are much higher than for monocular or binocular ones.
视觉系统时间分辨率的一种衡量方法是对相邻视觉刺激起始时间顺序的检测。阈值为几毫秒，其随刺激间隔的变化表明存在一个有限的处理区域。在两名观察者的中央凹和视网膜周边区域测量了这种距离函数。时间顺序检测阈值在离心率达20度的视网膜位置上变化不大，距离函数的宽度也变化不大，除了在中央凹附近。通过测试来自相反方向刺激对的信号相互抵消的范围，获得了对这种处理区域的独立估计。双眼分视刺激的阈值远高于单眼或双眼刺激的阈值。
