Speed, spatial-frequency, and temporal-frequency comparisons in luminance and colour gratings.
The perceived speed, temporal frequency, and spatial frequency of matched colour and luminance gratings were compared in separate experiments. The large factor by which colour gratings are perceived to be slower moving than matched luminance gratings cannot be explained by systematic differences in the perceived spatial frequency or in the perceived temporal frequency of the two types of grating.
