Final answer:
A memory strategy that uses a special kind of flash card is called a mnemonic device, which aids in organizing and encoding information into long-term memory through the use of vivid and unusual associations.
Step-by-step explanation:
A memory strategy that involves a special kind of flash card is known as a mnemonic device. These memory aids help us organize information for more effective encoding into our long-term memory. For instance, if one needs to remember the order of planets in the solar system, a mnemonic such as 'My Very Educated Mother Just Served Us Noodles' can be used to signify Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, respectively. Mnemonic devices can take various forms, such as acronyms, acrostics, rhymes, and even songs, all designed to make the information more memorable.
By creating associations that are vivid, unusual, or emotionally engaging, mnemonic devices exploit the human brain's preference for patterned or meaningful information, thus improving recall. Moreover, these strategies are beneficial across different subjects where volume or complexity of information presents a challenge for memorization. Regardless of the type, the effectiveness of a mnemonic is heavily dependent on its ability to create a lasting impression in the learner's mind.
