Abstract

In a sample of 108 male subjects, age 13 through 89, foveal CFF was measured using 10 light/dark ratios, 2/98 to 98/2, under two levels of surround luminance: 0.04 and 23.6 ml. One at a time, individual differences, surround, age, and the light/dark ratios were held constant in several analyses of variance. Stepwise, inductive regression equations were calculated. Reliability of the data varied as a function of the experimental conditions. All first-order variables, the second-order interactions with the exception of Age Ă—Surround, and the third-order interaction, were shown to significantly influence CFF. The best predictors of CFF were the lowest light/dark ratios, the primary variables, combined with age, the secondary variable.
