在眼睛最初过滤后的20分钟内，重复测量Pulfrich效应(当用滤光器在一只眼睛上观看运动刺激时的虚幻位移)。对于10种滤光片密度中的每一种，普尔夫里奇效应总是在滤过眼睛后立即发生，但随后在适应期内大大增加。结果表明，滤光眼的知觉潜伏期由两个因素增加：滤光片导致的刺激亮度降低和渐进性暗适应。暗适应显然是这两个因素中更重要的一个。
The Pulfrich effect (the illusory displacement of a moving stimulus when it is viewed with an optical filter over one eye) was measured repeatedly during a 20 min period following the initial filtering of the eye. For each of 10 filter densities, the Pulfrich effect always occurred immediately upon filtering the eye, but subsequently increased greatly during the adaptation period. The results indicate that the perceptual latency of the filtered eye is increased by two factors: the reduction in stimulus luminance due to the filter and progressive dark adaptation. Dark adaptation is apparently the more important of these two factors.
