Title: Optical Illusions
Post by: Gurn Blanston on November 05, 2010, 06:49:25 AM
So, what color are these spirals?

Curious if you see what I see... :)

I don't know if this counts.  I know some question the merits of this test, but this is supposed to determine how you think. 

Apparently, if you deem the image to be rotating counter-clockwise, it means you are a left brain thinker.  If you see the image rotating clockwise, you are more of a right brain thinker.


(http://goohackle.com/imgs/spinning-lady.gif)

I definitely am a left brain thinker, and I definitely see the image rotating counter-clockwise.  Although, after awhile, if I look away and look back at the image, for a brief moment, I can see the image turning clockwise.  Most of the time though, it is turning counter-clockwise for me.  My wife always sees it turning clockwise.

I'm a left-brain thinker. What does it say though that i focused on her breasts first?

[EDIT] Well, damn, i forced myself to see her go clockwise and now i can't get her to go the other way.

[EDIT2] Now i can see her go both ways at will. This test sucks.

Uncued, I definitely see it as moving clockwise. With a little mental effort, I can see it moving counter-clockwise instead.

There are no spirals, only concentric circles? This seems like a cop out though.

I don't want to discourage anyone from looking at pictures of spinning naked ladies, but I've yet to see any evidence to support the notion that the direction of rotation has anything to do with whether a person is left-brain or right-brain dominant, whatever that would mean.

And to be fair, shouldn't we have a comparable picture with a naked man?

The trick, I guess, is that orange is clearly perceived when contrasted with green, but orange looks like a lighter shade of pink when contrasted with magenta.  By blocking the screen so you can only see one color at once, you will notice that the light pink from the magenta/pink zone is the same orange as in the orange/green zone.  (A quick glance would lead you to think there are four distinct colors but there are only three, the pink in the magenta pink zone is identical to the orange in the green orange zone.)  Right?

The lesson is that the visual system is not good at evaluating absolute color values.  It is good at detecting contrasts with nearby colors.   So your perception of a color depends more on how it contrasts with nearby colors, than on that the color actually is.

No, I meant that the spirals are made form concentric circles, so they are there, but they aren't. No matter, it's not right.

Somehow I transposed the compositional roles of the pink and orange.

FWIW, I did not pay any particular attention to the sex of the rotating person.

Which may mean that I've failed this optical test, too

Post by: Octo_Russ on November 05, 2010, 08:42:58 AM
Yes, there are only 3 colours, the light blue and light green spirals are actually the same colour, but because the green has orange lines across it, and the blue has magenta lines across it, the brain computes to see the green and blue as two different colours, in fact they're an identical shade of green/blue.

The first thing I noticed is that the orange against green is the same as the pink against magenta.  But it you are right that the cyan against magenta is the same as the green against orange.   That is even less obvious.  The attached shows the three colors present is isolated bars.

The trick is that it looks like a green dot replaces the pink dots racing around the circle, but really the pink dot disappears and reverts to grey.

I don't think it has anything to do with left brain vs. right brain. You can will yourself to see her changing directions- you just have to relax and kind of switch your perception. It's not easy to do, but if you practice enough, it's possible.

If the answer hadn't had to be 'yes' (else you wouldn't have asked :) ) I wouldn't have believed it. They don't appear remotely close. :)

Now that would have been an illusion, had they appeared so.  ;)
