Top-Down Example

This image has four different planes layered on top of each other and rendered different colors so that one may correlate each plane with the below measurements of the plane. For top down processing, one with first will begin with short fixations (gaining attention) to get an overview and to map out the image. Next, there will be longer fixations, such as correlating the colors with each individual plane. Then after these fixations, one will look ahead with a priming of actions as much as  they can and remember what they saw, for example, that the yellow plane has the largest wing span. Next is the "just in time" strategy, so that if someone asks or they need to know in a fly they can answer quickly based on color, size, and/or shape.
