Final answer:
The hierarchy technique is a mnemonic device that emphasizes memory consolidation.
Step-by-step explanation:
The hierarchy technique is an example of a mnemonic device that emphasizes memory consolidation. Mnemonic devices are memory aids that help us organize information for encoding and retrieval. For example, using a mnemonic like Mr. VEM J. SUN can help remember the order of the planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. By linking information to existing knowledge, like using the acronym HOMES to remember the names of the Great Lakes, we can enhance memory through elaborative rehearsal.
