Four target sizes between 15 and 120 min. of arc with six luminance levels covering the range between 398.1 and 1.26 cd/m2 in steps of .5 log units were presented to 0, 20, 40, 60, and 80 degrees nasal retinal loci. In both peripheral and foveal viewing, magnitude estimates to apparent brightness judged by 12 Ss changed as a function of target size and luminance. The exponent of the power function was not dependent on retinal loci but on target size. However, when target size increased, the apparent brightness was slightly greater with peripheral viewing than with foveal viewing.
向鼻侧视网膜0度、20度、40度、60度和80度位置呈现四种视角大小的目标，视角范围在15到120分弧度之间，有六个亮度水平，亮度范围在398.1至1.26坎德拉每平方米之间，以0.5对数单位为步长。在周边视野和中央凹视野中，12名受试者对表观亮度的大小估计随目标大小和亮度而变化。幂函数的指数不依赖于视网膜位置，而是依赖于目标大小。然而，当目标大小增加时，周边视野下的表观亮度略高于中央凹视野下的表观亮度。
