ABSTRACT

Five sets of displays are presented to be viewed on the journal's website in conjunction with the text. The factors that give rise to the integration and disruption of the direction of apparent motion in two and three dimensional space is the central topic.

• The first set of displays examines what factors contribute to the integration and disruption of apparent motion in the Ramachandran/Anstis clustered bistable quartets.
• The second set examines what factors give rise to the perception of the direction of motion in rotating two dimensional wheels and dots.
• The third set examines how the depth cues of shading and disparity contribute to the perception of apparent motion of opaque displays.
• The fourth set examines how the depth cues of shading and disparity contribute to the perception of rotating unoccluded displays.
• The fifth set examines how the depth cue of motion parallax influences the perception of apparent motion.

Throughout we make inferences about the role various parallel pathways and cortical areas play in the perceptions produced by the displays shown.
