Over 70% of information is forgotten – this frequently forces us to review, re-read or even repeat things that we want to learn and memorize in the long term. Several studies have shown that if we associate one thing with another, this creates connections that enable us to boost the process of memorization. We call these methods “memo techniques”. If associated with a sensation or an emotion, memorization is even more uncoupled, since the information is perceived as striking and is anchored more firmly in the brain. We all know of Proust’s madeleine, where an aroma sparks an emotion that awakens in the hero a mass of memories buried until that moment.
