A target of 44 min of arc with luminance of 1.03 log cd/m2 of 50 msec duration was presented to the loci along each of nasal, temporal, superior, and inferior half retinal meridians covering the eccentricity between 10 degrees and 50 degrees in steps of 10 degrees units. Two graduate students, serving as Ss, were instructed to point out the perceived locus where the target had appeared. The visual angles between the perceived and physical locus of the target were increased as a function of retinal eccentricity due to refraction.
一个时长50毫秒、亮度为1.03 log cd/m²、视角为44分弧度的目标被呈现给沿着鼻侧、颞侧、上半侧和下半侧视网膜子午线的各个位点，覆盖10度到50度的偏心率，步长为10度单位。两名研究生作为受试者，被要求指出目标出现的感知位点。由于折射，目标的感知位点与实际位点之间的视角随着视网膜偏心率的增加而增大。
