• In humans, visual processes use retinotopic coordinates. However, not all processes are strictly retinotopic. We used a variant of the Ternus-Pikler stimulus to examine whether pigeons, visually dominant vertebrates, share the same retinotopic and non-retinotopic processing as humans. Six humans and four pigeons were required to discriminate the rotational direction of target disks surrounded by other nonrotating disks. When all disks flickered in synchrony and moved in tandem back and forth, target localization in humans was hampered but that in pigeons was not affected. These results suggest that visual processes in humans can be accomplished with using non-retinotopic coordinates, but those in pigeons are strictly retinotopic.
