Abstract
The fusion frequency of flicker (F.F.F.) was measured in 23 normal subjects at 5 light: dark ratios (extremes of light interval: 20 and 98% of total cycle length), at a brightness of 30 foot-lamberts. The F.F.F. decreased in a nearly linear fashion when plotted against the logarithm of the dark: light ratio. It is suggested that the F.F.F. depends on a critical length of the dark intervals (refractory period).Keywords
