The following movies supporting our papers are available here

Please Note: these movies are for demonstration purposes only, as second order stimuli need to be displayed on accurately gamma corrected screens.

Motion transparency arises from perceptual grouping: evidence from luminance and contrast modulation motion displays, Current Biology 6 (1996) pp 1343-1346 Download .pdf [movie showing transition between transparent and rotational motion] (.avi format) Explanation: As the background luminance changes, it passes through a level where the stimulus is second order (depending on the gamma of your screen), at which stage the transparency breaks up.
