La técnica funciona porque el cerebro trata las palabras desconocidas como ruido hasta que tiene contexto suficiente para descifrarlas.

I · Down the Rabbit-Hole
Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, “and what is the use of a book,” thought Alice “without pictures or conversations?”
Alicia empezaba a cansarse mucho de estar sentada junto a su hermana en la orilla y de no tener nada que hacer. Una o dos veces había mirado el libro que leía su hermana, pero no tenía dibujos ni conversaciones. «¿Y de qué sirve un libro —pensó Alicia— sin dibujos ni conversaciones?»
So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her.
Así que estaba pensando (tan bien como podía, porque el calor le daba mucho sueño y la atontaba) si el placer de hacer una guirnalda de margaritas compensaría la molestia de levantarse a recogerlas, cuando de pronto pasó corriendo muy cerca de ella un Conejo Blanco de ojos rosados.
Spaced repetition review
The words you looked up come back as practice
Practise a course or the words you saw while reading. Wrong answers get a native-language hint and the dictionary, and the next review follows a forgetting curve.
Install it, then open a page in the language you’re learning.
