In the dominant hemisphere, usually the left, which area is associated with phonologic retrieval and comprehension of written and spoken language?

• A. Frontal lobe
• B. Prefrontal cortex
• C. Primary auditory cortex
• D. Sensory speech area of Wernicke

Answer: (D)

Language comprehension and phonologic processing rely on Wernicke's area in the dominant temporal lobe. This sensory speech area decodes the sounds of speech and maps them to meanings, enabling understanding of both spoken language and written language through phonological decoding. The left hemisphere’s Wernicke’s area is specialized for processing language rather than general auditory perception or movement. The other regions mentioned are linked to broader functions: basic auditory perception in the primary auditory cortex, and higher-order planning or executive functions in the frontal or prefrontal cortex.
