This image is an example of top-down visual processing. It is an optical illusion of a mysterious figure that is haunting the fox. For this image, we are using top-down visual processing to look for the mysterious figure lurking in the forest. Top-Down visual processing is "driven by the need to accomplish some goal" (Ware, p.12), which consist of goal-directed eye movement. This is when the viewer have short fixation to get an overview of the image, such as the optional illusion of the fox. At a glance, the viewer only see a forest, this refer to how the viewers creates a biased goal in whatever they prefer to see. But if the viewer take a longer look at the image, the mysterious figure haunting the fox is a big fox.
