the rods seem to move to the rite because they are spinning to the rite

You aren’t going mad. It DOES look that way!

Bzzz… I suppose if you move those rollers, and change the direction of the rolling, it’ll be the exact opposite. Illusion, man! Illusion!!!

I see it when I dont look directly at the image (like when I read the text right to the image)

In general, a moving stimulus on stationary background causes urgency for the visual system to repond quickly even if it is presented on fovea, because it introduces a high level of contrast which readily calls immediate attention for further processing. High contrast in brightness, color or other features means it has a high level of energy, variations or uncertainty in the region of stimulus. It could be a predator or a prey. Perhaps, peripheral vision may have been equipped to detect this high spatial or temporal contrast stimulus rather than to provide details. In fact, receptors on the periphery are far larger than those on fovea, not well suited to extracting accurate location information.

I think, that our ancestors had a big evolutionary advantage, if their peripheral vision was very sensitive to moving objects, so that they could notice predators earlier than others. The price we have to pay for it (beeing fooled by an optical illusion that is simulating motion) seems not too high, regarding that if they hadn’t developed this sensitivity, we would not be here…

Please place some patterns on the surround, varying size, orientation, even more moving them with differing directions and speed. This will make a decent study with which you can publish in a major international, peer reviewed journal, before then, you may want to do some literature review whether this is a new illusion or not.

This effect can be understood in terms of local-global motion paradigm and foveal vs. peripheral motion. In the latter paradigm, I can tell one thing: localization of feature extracted in the periphery is less accurate than it is on fovea.

Maybe were all going mad!
