Top down visual processing is “driven by the demands of
attention, which we determined by the needs of the tasks” (Ware). This type of processing is goal biased,
and focused on attention. The puzzle pictured above is an example of top down
visual processing. For the user,
the goal is to complete the puzzle, which requires focused attention on the
uniquely cut squares in order to figure out which ones fit with the rest. Most of the puzzle is in one color, so
attention is focused on the shapes, rather than the colors.
A cockpit of an F-22 is another example of top down visual processing. A pilot must focus his attention on the
relevant information by scanning back and forth between what is being displayed
on each gauge and screen. The goal
is to read every bit of information in order to navigate, or accomplish another
necessary task.
