Three quick brain teaser games to test your perceptual and cognitive skills

An always delightful way to learn more about our brains and minds is to experience so-called optical illusions and to see how we react to them. Below you have three fun ones to tease, and probably even puzzle, you mind. Ready, set, go! 1. Where is that couple’s baby? 2. Are those two orange circles of the same exact size, or not? 3. Is it all black and white, or are there gray dots below, at the intersections?   ANSWERS AND EXPLANATIONS 1. Can you see that couple’s baby? You should be able to see a couple, a large tree … and an even larger baby, facing upwards. This is a great example of an illusory contour. The baby’s head is on the left, the baby’s feet are against the trunk of the tree on the right.. 2. The Ebbinghaus Illusion The two orange circles are exactly the same size, even though the one on the left seems much smaller. This size distortion is caused by the size of the surrounding circles and their distance to the center circle.. 3. Hermann Grid illusion There are not gray dots in this grid. However, probably you perceive some ghostlike gray blobs at the intersections of the white lines — incredibly those gray dots disappear when you look directly at them. See below a beautiful example of the Hermann Grid illusion in the real-world: You will notice faint white circles appear where the horizontal and vertical slats intersect in the window frame (even if no white circles are there at all!)
