Abstract:
Concentric gratings that expand outwards are seen for a greater period of time relative to contracting gratings when engaged in binocular rivalry. During binocular rivalry (BR), which is a fluctuation in visual awareness between different images presented separately to each eye, equivalent images tend to be seen in equal proportion over the observation period. When one eye's image is particularly salient, brighter, or moving, this equality is curtailed, and the stronger image predominates. Here a specific direction of motion is found to predominate over another of equal speed. This tendency is consistent with the ability of looming objects to orient attention, coupled with previous accounts of the role of stimulus-driven attention in BR.

Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
