What is top-down vs bottom-up processing?

Bottom-up processing begins with the retrieval of sensory information from our external environment to build perceptions based on the current input of sensory information. Top-down processing is the interpretation of incoming information based on prior knowledge, experiences, and expectations.

What is top-down processing and how does it help us see how can it cause problems?
