Colour Motion Asynchrony (CMA)

The red dots are moving up and down for exactly the same duration, but we hardly perceive them moving up.

Colour Motion Asynchrony (CMA)

Now the percept changes a bit. The red dots are moving exactly as in the first example, but we might be able to see them moving up. If you want to know more: Linares, D. and López-Moliner, J. (2006). Journal of Vision, 6:974–981

Revealing image decomposition from MAE

Half-spiral having a radial component of contraction. Even though we perceive a clear rotation, it can elicit an expansion motion after-effect. In order to see the motion after-effect, first check the loop option and look at the stimulus for one minute and stop it by clicking on the movie with the mouse. A Double click restarts the movie. See Lopez-Moliner, Smeets & Brenner (2004) for more information.
