This lecture discusses two methods to improve memory retention: mnemonic cues and spaced repetition. Mnemonic cues use associations and stories to help remember information, such as a movie in the head to remember the Korean symbol for “umbrella.” Spaced repetition is a memorization technique where flashcards are arranged based on how well the answer is known and reviewed at varying intervals. The speaker recommends putting known cards at the back and unknown cards in the middle or front for efficient memorization.
Mnemonic cues involve using associations and stories to remember information. For example, the speaker used a movie in his head to remember the Korean symbol for “umbrella” by imagining a movie of an umbrella opening and closing. The human mind encodes things based on stories and points of connection, making it easier to remember things.
Spaced repetition involves memorizing certain things and using flashcards with prompts on one side and answers on the other. The speaker recommends placing known cards at the back, middle, or front for more frequent review. This simple method is the most efficient and may employ different variations.
