Zusammenfassung
We investigate the perception of motion in chromatic stimuli with no brightness contrast. To this end a set of 16 equiluminant colors was established for each observer. A motion stimulus is used, whose area is filled with any of the 16 test colors and presented on a grey background equiluminant to the colors. This stimulus is used to simultaneously perform experiments that measure at which end (where) it is moving (detection) and in which direction (identification). In all subjects identification thresholds were clearly lower that detection thresholds. The experiments are discussed with respect to new anatomical and functional evidence in the geniculo-cortical pathway.
