Top- Down Visual Processing

http://www.pep-web.org/document.php?id=psar.087.0591a.fig001.jpg

This optical illusion operates on our visual perception of contours. Depending on whether the black or white is seen, the brain will interpret whether two faces are shown or a vase. This is really the perfect example of constant linking and relinking of visual information in a top- down process. There is a very high level of attention for such a simple image as we try to grasp what is going on. This is an important image in terms of graphic design because it really relates to the efficiency of the design and how the information is translated. What t is essentially is goal- based eye movement through the image. It doesn't really matter what you originally see in the image, you will look it over again to see if your view was correct or if you missed something.
