The symbol grounding problem asks how computational symbols acquire meaning. If a computer manipulates symbols according to rules, what connects symbols to what they represent? Unlike humans who learn 'apple' through sensory experience, a computer's symbol 'apple' seems ungrounded—related only to other symbols. Some propose embodied cognition as a solution: meaning emerges through physical interaction with the world, suggesting that disembodied AI may lack genuine understanding.

Based on the passage, it can be inferred that

A

all symbols in computers are already fully grounded through their formal definitions

B

human learning never involves sensory experience

C

physical embodiment is irrelevant to cognitive processes

D

the capacity to manipulate symbols formally may not be sufficient for understanding their meaning

Correct Answer: D

Choice D is the best answer. Symbol manipulation alone may leave symbols ungrounded.

  1. Context clues: A computer's symbols seem "ungrounded—related only to other symbols."
  2. Meaning: Formal manipulation may not constitute genuine understanding.
  3. Verify: The suggestion that disembodied AI may "lack genuine understanding" confirms this.

đŸ’¡ Strategy: When a formal process is questioned for lacking a key feature (grounding), infer formal processing may be insufficient.

Choice A is incorrect because the whole problem is that computational symbols seem ungrounded. Choice B is incorrect because humans learn through "sensory experience." Choice C is incorrect because embodied cognition proposes physical interaction grounds meaning.
