Illusions

This image you see is created by Rupert Sheldrake, and was part of a TV experiment in 1983 with 2 million BBC viewers. Sheldrake wanted to test his theory of morphogenetic fields, and from this theory, the knowledge of other people can influence your own. In other words, if many people know what this picture is, you would also recognize it easier. The best part is that the results were surprising... I found this image on planet perplex, and believe it or not, had some hard time figuring out what it represents. How long did it take you to see the hidden meaning? Let's make a test of our own

I replied by PM so as not to mess it up.

Did you know that your eyes have blind spots (and not just at the back of your head)? Each of your eyes contains an area that has no photoreceptors because it is occupied by the optic nerve. You may not have noticed these areas because they are on opposite sides of your visual field. However, this exercise is designed to isolate your blind spot and you will be amazed at the results.

Instructions: Close your left eye and fixate your right eye on the cross in the first diagram. If your eye is about 12 inches (30 cm) away from the monitor, you should notice that the round dot disappears. This distance may vary according to the screen resolution you have set.



You may be surprised to see that the dot is replaced, not by a black region, but rather blank white space. The brain simply \"fills in\" the most probable stimulus (in this case, a uniform white area) where there is none.

The following example demonstrates the \"filling-in\" phenomenon in greater detail. Apply the same instructions as given before and you should notice the red marking is replaced by the most probable pattern that your brain is able to perceive.
