||When colours move.
Discusses the experiment by S. J. Cropper and A. M. Derrington (see record 84-00193) which reveals that color, as well as luminance, contributes to motion perception. The similarities of motion responses to color and to luminance stimuli point to the processing of several independent measurements by the brain as a strategy for improving the reliability of visual analyses. Their experiment shows that, as required for optimal integration, the chromatic input to this integrated site is derived independently of the luminance input.
