Beyond flashcards: five evidence-backed techniques to lock new words into long-term memory — chunking, imagery, the testing effect, interleaving, sleep.
Flashcards work, but they're not the only tool. Five techniques from memory research, all easy to apply to vocabulary:
The brain remembers patterns better than isolated items. Instead of memorising increase, decrease, fluctuate, stabilise, rise, fall one by one, learn them as "change verbs" and notice how they differ.
When you see a new word, ask: what other words is this related to? Group them.
Pick a vivid mental image for the word. For ravenous (very hungry), picture yourself attacking a giant burger. The weirder, the better — bizarre images stick.
This technique (the keyword method) is one of the most-replicated findings in cognitive psychology. Adults learn ~2x faster with it compared to translation alone.
This is the single most under-used technique. Re-reading a word + definition feels productive. It barely works.
Instead: see the word, hide the definition, try to recall it. Even guessing wrong, then checking, builds more memory than reading the answer ten times.
Studying 50 words from one chapter all in one go feels good. But research consistently shows mixing different categories (verbs + nouns + idioms, or topic A + topic B + topic C) creates stronger long-term memory.
Counter-intuitive but solid: blocked practice feels easier; interleaved practice retains better.
Vocabulary you encounter for the first time gets consolidated during sleep, especially deep sleep. Two practical implications:
The compound effect of stacking 2-3 of these is far bigger than any single technique. A practical setup:
Tilingu does steps 3 and 4 automatically — you just need to bring the words and show up daily.
