Visual Perception Brain Teaser
By: Caroline Latham
Is the inner shape a real circle?
Hint:
Sometimes extraneous information around your target can distort your view. Try covering the lines with a piece of card to remove some of the interfering information.
Brain Use:
Here you are exercising your visual perception and decision-making skills. The visual cortex in your occipital lobes processes visual input from your eyes. Not only is the occipital lobe mainly responsible for visual reception, it also contains association areas that help in the visual recognition of shapes and colors. Problem solving, selective attention, and executive functions used in this exercise are handled by the anterior portion of the frontal lobes.

Ok! I finally got one. I could see the circle within the circle. Then I tried to complicate it by looking for a mathmatical solution.
Glad you got it Randy! I think the moral of that story is simplify!

I could see past the lines and see the circle as it would appear on its own – a perfect circle.
Yes
its a perfect round circle
I see two circles although portions of the rounded lines are broken. I don’t get it.
That’s good: they are 2 full circles. The interior one may look like an oval given its positioning-this is a visual illusion.
Well Alvaro, my visual illusion only allows me to see the circles. I tried to look for the oval, but couldnt find it. Thxs
wow that was well…interesting..
if you look at the center of the outer circle then you can see that the inner circle is not perfect. peripherals everybody.
yes. inner shape is a circle
In my perception it is not looking like correctly circle, but like circle.
ya…. it looks like a circle
I thought it was a perfect circle. When I first looked at it, I thought it wasn’t. When they asked me to see if it was, I looked closer and saw that it was.
yes; it just appears to not be one b/c of the angle.
