Top-Down Visual Processing



Figure 1: A classic illusion and example of Top-Down Visual Processing. Top-Down Visual Processing is more action and goal based than Bottom-Up Visual Processing. We are constantly preparing ourselves for what might happen next and how we will need to respond. This image was found at www.mozglubov.blogspot.com.





Figure 2: With Top-Down Visual Processing,our goal when looking at this image is to see the entire picture. At first all we can see are scattered black dots. Then we notice a collection of dots in the form of a dog, a Dalmatian. This image was found at www.thelitelights.com.



Figure 3: This image contains four circles each with a quarter of the circle cut out. However, non-visual information is so powerful, that in this case viewers visualize a superimposed white square resting on top of the four circles. This image was also found at www.mozglubov.blogspot.com.
