How many different words does the average 20-year-old know?

• Between 10,000 and 20,000

• Between 27,000 and 52,000

• Between 55,000 and 70,000

• Over 100,000

What is the brain's primary role in speech comprehension?

• Sequential processing of words one after another.

• Storing words in a single, dedicated memory unit.

• Acting as a parallel processor, handling multiple tasks simultaneously.

• Filtering out all but the most common words.

What happens at the "recognition point" during speech comprehension?

• The brain activates all possible meanings of a word.

• Only one firing pattern, corresponding to the correct word, remains active.

• The brain begins to store the word in the hippocampus.

• All active units suppress each other, leading to confusion.

How does the brain initially store and integrate new words?

• New words immediately overwrite old, less frequently used words in the cortex.

• New words are stored in the hippocampus and then gradually transferred to the cortex during sleep.

• New words are stored in a temporary memory bank and deleted if not used frequently.

• New words are directly integrated into the cortex during waking hours.
