Try observing the world as though there were no such thing as top-down processing. For example, without the aid of top-down processing, seeing a restaurant’s restroom sign that says “Employees must wash hands” could be taken to mean that we should wait for an employee to wash our hands! If you try this exercise, be warned that it is extremely difficult because top-down processing is so pervasive in our environment that we usually take it for granted. L01
