What is top-down and bottom-up processing in perception?
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 Bottomup perception?
Bottom-up processing is an explanation for perceptions that start with an incoming stimulus and working upwards until a representation of the object is formed in our minds. It is in the next step of the process, known as perception, that our brains interpret these sensory signals.

What does Gregory’s top down theory of perception mean?
