1885-yilda nemis psixologi Hermann Ebbinghaus g'alati tajriba o'tkazdi: u o'ziga ma'nosiz bo'g'inlar ro'yxatini (masalan, “DAX”, “BOK”) yodladi va keyin ularni qancha vaqtda unutishini o'lchab bordi. Natija — “unutish egri chizig'i”: yangi o'rganilgan ma'lumot dastlabki soatlar va kunlarda juda tez yo'qoladi, keyin esa sekinlashadi.

Yechim — oraliq bilan takrorlash

Ebbinghaus yana bir narsani payqadi: takrorlashlar vaqtga taqsimlansa, xotira ancha mustahkam bo'ladi. Bu “spacing effect” (oraliq effekti) deb ataladi va psixologiyadagi eng ko'p tasdiqlangan topilmalardan biri.

2006-yilda Nikolas Sepeda va hamkasblari bu mavzudagi tadqiqotlarni jamladi: 184 ta maqoladagi 317 ta tajriba. Xulosa: oraliq bilan o'qish bir martada “siqib” o'qishdan yaxshiroq natija beradi. Bundan tashqari, ma'lumotni qancha uzoq eslab qolish kerak bo'lsa, takrorlashlar orasidagi oraliq ham shuncha uzunroq bo'lishi kerak.

Bir kecha 5 soat o'qigandan ko'ra, 5 kun davomida 1 soatdan o'qigan yaxshi.

Amalda qanday qilinadi?

• Bugun o'rganing, ertaga takrorlang. Birinchi takrorlash eng muhimi — unutish eng tez boshlanadigan payt.
• Oraliqni asta uzaytiring. 1 kun, 3 kun, 1 hafta, 2 hafta.
• Takrorlashda o'zingizni tekshiring. Qayta o'qimang — kitobni yopib, eslab ko'ring.
• Kartochka ilovasidan foydalaning. Anki yoki Quizlet takrorlash vaqtini o'zi hisoblaydi.

Saytdagi lug'at bo'limi va kartochka ilovalari (masalan, Anki) aynan shu tamoyilga qurilgan: so'z unutilishiga yaqin qolganda yana ko'rsatiladi.

In 1885, the German psychologist Hermann Ebbinghaus ran an unusual experiment: he memorised lists of meaningless syllables (such as “DAX” and “BOK”) and then measured how quickly he forgot them. The result was the “forgetting curve”: newly learned material disappears very quickly in the first hours and days, and then the loss slows down.

The fix: spaced repetition

Ebbinghaus noticed something else: when reviews are spread out over time, memory becomes much more durable. This is called the spacing effect, and it is one of the most thoroughly confirmed findings in psychology.

In 2006, Nicholas Cepeda and colleagues pooled the research on this topic: 317 experiments from 184 papers. The conclusion: spaced study produces better results than cramming. And the longer you need to remember something, the longer the gaps between reviews should be.

One hour a day for five days beats five hours in a single night.

How to do it in practice

• Learn today, review tomorrow. The first review matters most: that is when forgetting is fastest.
• Stretch the gaps gradually. 1 day, 3 days, 1 week, 2 weeks.
• Test yourself when you review. Do not reread: close the book and try to recall.
• Use a flashcard app. Anki or Quizlet schedule the reviews for you.

The site's vocabulary section and flashcard apps such as Anki are built on exactly this principle: a word comes back just before you are about to forget it.
