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.
