Attention can be categorized into two distinct functions: bottom-up attention, referring to attentional guidance purely by externally driven factors to stimuli that are salient because of their inherent properties relative to the background; and top-down attention, referring to internal guidance of attention based on

What the difference between bottom-up and top down processing?
So, bottom-up processing is data-driven, and your perception of what it is that you’re looking at directs your cognitive awareness of the object. So, in contrast, top-down processing basically uses your background knowledge, so uses your background knowledge to influence perception.

Studies related to attentional control and performance take two differing approaches. Specifically, research on attentional capture has two modes: voluntary and reflexive. The voluntary mode is a top down approach where attention is shifted according to high-level cognitive processes.
