Square-wave gratings of various space-average luminances, spatial frequencies and orientations were presented briefly to observers, who were asked to adjust a brief visual probe to coincide with the end of the longer-lasting, gradually decaying sensory trace of these stimuli. Visible persistence of 2 and 7 c/deg gratings increased with increasing luminance, and an interaction was found at approx. 6 cd/m2 between luminance and spatial frequency. The persistence curves showed a low-pass frequency characteristic at low mean luminance levels, whereas at high luminances, they presented a band-pass frequency characteristic. Persistence of a 7 c/deg grating was longer at oblique orientations than at horizontal or vertical orientations. These findings were related to properties of transient and sustained channels in human vision.
向观察者短暂呈现具有不同空间平均亮度、空间频率和方向的方波光栅，要求他们调整一个短暂的视觉探针，使其与这些刺激的持续时间更长、逐渐衰减的感觉痕迹的末端重合。2和7周/度光栅的可见持续性随亮度增加而增加，并且在大约6坎德拉/平方米处发现亮度和空间频率之间存在相互作用。持续性曲线在低平均亮度水平下呈现低通频率特性，而在高亮度下呈现带通频率特性。7周/度光栅在倾斜方向上的持续性比在水平或垂直方向上更长。这些发现与人类视觉中瞬态和持续通道的特性有关。
