Which statement describes bottom-up processing?

• A. The reader is decoding the language itself.
• B. The reader relies on world knowledge to guess meaning.
• C. The reader ignores vocabulary entirely.
• D. The reader only uses punctuation.

Answer: (A)

Bottom-up processing builds meaning from the smallest units of language—letters, sounds, and word forms—and then combines them into words, phrases, and overall sense. This approach is data-driven: you focus on decoding the language in the text itself, letting the perceptual input guide understanding rather than starting from what you already know or expect about the topic. So decoding the language itself, by turning print into sounds and grammatical units and using that information to derive meaning, best describes bottom-up processing. In contrast, using world knowledge to guess meaning relies on prior knowledge (top-down processing), and treating vocabulary or punctuation in isolation doesn’t capture the full language-driven buildup of meaning.
