At the core of retrieval practice is a technique called the spacing effect or spaced reinforcement - and this is the exact opposite of “one and done” training. Spacing the learning focuses on repeating information over time while making sure there are specific intervals between each repetition so a little bit of forgetting actually happens (to help strengthen the brain "muscle" or recall ability).
Trivie combines recall probability and score data, predicts when a user is starting to forget a piece of information, and automatically generates a personalized cadence of quizzes to help the learning stick (similar to “intelligent” digital flashcards know when you are starting to forget). This reinforcement protocol is also combined with two additional concepts that make up retrieval practice - varied content types and interleaving.

Trivie uses a wide range of content types. Neuroimaging studies suggest that different kinds of content engage different parts of the brain, and the learning of motor skills from varied content appears to be associated with an area of the brain that is good at decoding more difficult concepts. As such, varying content formats are extremely important in building long-term associations. In other words, some people learn from pictures, some from text, and some from a video. Trivie supports all three, along with over 100 additional content types.
When you interleave content of two or more subjects or skills, it further strengthens memory. Essentially, you are weaving together ("interleaving") topics that may be somewhat related, but not in a linear fashion, so your brain builds deeper neural connections and becomes stronger.
