How not to forget this word
Reading a word and remembering it are different jobs. A day later, little survives of a single reading — and that is not bad memory, that is how memory works.
- This has been tested on foreign words too. The difference shows up most when you test yourself a few days later rather than straight away.checked many timesKim & Webb, 2022, Language Learning 72(2) · 48 experiments, 3,411 participants, 98 comparisons.
