Outline of Final Research Achievements

We have found some new pieces of evidence on the mechanisms of human visual motion perception and the underlying brain mechanisms. Major findings: 1) we found that the spatial frequency dependency in speed perception is the basis of the recently created Spinner illusion (A. Ho & S. Anstis). 2) we found brain areas that are responsible in visual self motion perception, and re-discovered the white matter fascicle connecting these areas. 3) discovery of audio-visual interaction that is specific to looming motion and is dependent on spatial congruence. Dr van Tonder, who was initially a formal member of this project, has developed a computational model for anomalous motion illusions, which was presented at a conference but is still under development for publication.
