Explanation;

-The names "top down" and "bottom up" refer to the level of a perceptual system operating in perception.

-Top down processing is based on what is already in the mind or (highest levels of) the brain. It is how our brains make use of information that has already been brought into the brain by one or more of the sensory systems. Top-down processing is a cognitive process that initiates with our thoughts, which flow down to lower-level functions, such as the senses.
