The science
Working memory holds only 7±2 chunks (Miller, 1956). A mnemonic encodes a long list into a single memorable chunk, bypassing this limit. First-letter mnemonics produce recall rates ~50% higher than rote repetition (Bellezza, 1981). Adding a vivid mental image — dual coding (Paivio, 1971) — further boosts retention.
