The Science of Spaced Repetition System (SRS) in Language Learning

What is the Forgetting Curve?

In the late 19th century, psychologist Hermann Ebbinghaus discovered the "Forgetting Curve," illustrating how quickly we forget new information if we make no attempt to retain it. Within 24 hours, you can lose up to 70% of newly learned vocabulary.

How Spaced Repetition Solves This

Spaced Repetition System (SRS) is a learning technique that incorporates increasing intervals of time between subsequent review of previously learned material. Instead of reviewing a word every single day, you review it after 1 day, then 3 days, then 7 days, and so on. AI-powered apps like EatVocabulary optimize these intervals perfectly for each individual word based on your performance.

Why EatVocabulary Does It Better

While traditional flashcard apps use generic SM-2 algorithms, EatVocabulary combines SRS with Multimodal AI. When you fail to recall a word, it doesn't just show you the answer; it generates a custom mnemonic hint or etymology breakdown to build a deeper neural pathway.
