Anki's implementation of the algorithm has been modified to.Īs you may know, Anki is an open-source flashcard app that uses spaced repetition algorithms to help you prevent natural forgetting. ' Anki' is the Japanese word for 'memorization'.The SM-2 algorithm, created for SuperMemo in the late 1980s, forms the basis of the spaced repetition methods employed in the program.
“Once information is interrelated with prior knowledge in long-term memory, it tends to remain stored, if not necessarily accessible.”Īnki is a free and open-source flashcard program using spaced repetition, a technique from cognitive science for fast and long-lasting memorization. when you were most alert maybe you could have answered it if you’d just racked your brains a little harder.įrom “Self-Regulated Learning: Beliefs, Techniques, and Illusions“: So you may be tired after doing Anki for 4 hours and that body state will negatively affect your ability to retrieve the answer maybe you could have answered that card at 10 a.m. Contextual cues, including environmental, mood state, body state cues etc, will influence the accessibility of a memory representation. There are a lot of factors affecting your retrieval strength, i.e., recalling the correct answer. I discovered this brutal New Interval setting only after 4 years of using Anki.
If you then fail it ONCE (pressed ‘Again’), Anki would banish the card back to square one. In the default Anki setting, if you get a card wrong, the New Interval for lapses would render it new again, like you’ve never seen or learned that card.įor example, you have answered a card correctly (pressed ‘Easy’) for 10 times over 3 years. If the card had a 100 day interval, the default of 0% would reduce the interval to 0 New interval controls how much Anki should reduce the previous interval by.
