Which processing approach relies on existing knowledge and expectations to interpret sensory input?

• A. Top-down processing
• B. Bottom-up processing
• C. Parallel processing
• D. Transduction

Answer: (A)

Top-down processing relies on prior knowledge, expectations, and context to interpret sensory input. Your brain uses what you already know to shape perception, filling in gaps and guiding interpretation when the sensory signal is unclear. For example, in a foggy scene or when a sentence is misspelled, your understanding of context helps you recognize what’s being perceived. Bottom-up processing starts with raw sensory data and builds up perception without using expectations, so it’s data-driven rather than guided by prior knowledge. Parallel processing involves analyzing multiple features at once across different pathways, not about using expectations to interpret input. Transduction is the conversion of sensory energy into neural signals, a physiological step that happens before interpretation. So the approach described is top-down processing.
