Abstract
Recently, a model was proposed to describe the brightness of time-dependent stimuli
(Roufs and Pellegrino van stuyvenherg, 1979). In order to test this model a
brightness-matching and a brightness-scaling method have been used to investigate
the influence of the flash duration on the relationship between brightness and
luminance for flashing point sources. It was found that 1. the exponent of the
power function describing the relationship between brightness and luminance, is
independent of the flash duration and 2. the results of brightness-matching and
scaling experiments are mutually consistent for one subject if it is assumed that
the brightness impression is determined by the effective luminance, i.e. luminance
above threshold. This has led to a revision of the model.
