Describe top-down and bottom-up processing as they apply to perception. When is each method used and when is it appropriate to use both?
Please provide the best answer for the statement.
Bottom-up processing involves the method of perception where information is processed from raw data or environmental stimuli and then sent up to the brain. This method is often used when we have not experienced the sensation before. Top-down processing is perception that relies heavily on previous knowledge and experience. This is often used when we have experienced the sensation or situation before. Most often, both bottom-up and top-down processing are used in interpreting most sensations.
