Gb. Henning et Am. Derrington, SPEED, SPATIAL-FREQUENCY, AND TEMPORAL-FREQUENCY COMPARISONS IN LUMINANCE AND COLOR GRATINGS, Vision research, 34(16), 1994, pp. 2093-2101
The perceived speed, temporal frequency, and spatial frequency of matc
hed colour and luminance gratings were compared in separate experiment
s. The large factor by which colour gratings are perceived to be slowe
r moving than matched luminance gratings cannot be explained by system
atic differences in the perceived spatial frequency or in the perceive
d temporal frequency of the two types of grating.
