研究了30名受试者主观轮廓的表观强度随光照水平、体型大小和观看距离的变化。以真实轮廓标准为模数的幅值估计被用来测量虚幻轮廓的感知强度。光照水平和视网膜大小都是主观轮廓表观强度的强大决定因素，产生的幅度估计从真实轮廓模数的20%-96%不等。据报道，在非常暗的光照(0.10loglx)下，视网膜较小(1.2-4.8度)的人的主观轮廓特别强烈。
The apparent strength of subjective contours was investigated in 30 human subjects as a function of illumination level, figure size and viewing distance. Magnitude estimation, with a real contour standard as the modulus, was used to measure the perceived strength of the illusory contours. Illumination level and retinal size are both powerful determinants of the apparent strength of subjective contours, generating magnitude estimates varying from 20-96% of the strength of the real contour modulus. Particularly strong subjective contours were reported for figures of small retinal size (1.2-4.8 deg) under very dim illumination (.10 log lx).
