Spaced repetition made simple

Spaced repetition means returning to material after a gap. Retrieval practice means trying an answer before checking it. For names, you can combine them: come back on another day, hide the written name, try to say it and then check.

Two people learn the same forty names. One repeats the list in a single sitting until it feels solid. The other uses short practice sessions over the next days and weeks. For many kinds of learning, the second plan helps memories last longer. The size of the effect depends on what you learn and when you practise.

Why the timing matters

In his experiments in the 1880s, Hermann Ebbinghaus learned lists of made-up syllables. He tested himself and measured how much time he saved when relearning a list after a gap. His syllables were designed to reduce familiar word meanings, although they could still differ in how easy they were to learn. A later replication explains his method and its limits.

His work gave us the basic idea of a forgetting curve. We often forget fastest soon after learning, then the loss slows down. There is no single curve for every person or every subject. Meaning, old knowledge, sleep and later practice can all change it.

For names, two lessons are useful.

Practise early. You may forget fastest just after learning. A same-day try lets you strengthen the name or fix a mistake.

An easy answer can earn a longer wait. If you remember a name after one day, you may wait three days before the next try. As the name gets easier, the waits can grow from days to weeks and then months. Each person and each name may need a different plan.

Why cramming can mislead

Cramming can make you feel sure that you know the names.

Read a team list again and again, and the names soon look familiar. That feels good. It does not show that you can say a name in the corridor three days later. Practice after a wait often feels harder. Some names come slowly and some are gone. That is normal. The task now looks more like the real moment when you need the name later.

Researchers sometimes call this a desirable difficulty. The practice feels harder now, but it may help the answer last. Easy practice is not always strong practice.

What a recall attempt adds

There are two basic ways to review a name. You can look at the face and written name together. You can also hide the written name, look at the face, say the name from memory and then reveal the correct answer.

Carpenter and DeLosh's face–name experiments compared recall with copying visible answers. Repeats were separated by other items within one session, with a five-minute break before the final test. Spaced and tested names were better retained. This does not validate a weekly schedule.

For name practice, keep the written name hidden until you have said your answer. Then reveal it and correct any mistake before moving on. The attempt asks you to bring the name to mind instead of only seeing it on a page.

Choosing the next practice date

Try again too soon and the answer may still be fresh. That can feel easy without helping much later. A few close tries can help a new name, but many repeats in one sitting can fool you. Wait too long and you may forget the name. You then need more time to learn it again. This does not mean that all the old work is gone.

Aim for the space in the middle. Wait long enough that the name takes some effort, but not so long that every card feels new. No fixed set of dates works for every name. The next date should change after each answer.

How easily you remember a name can guide the next practice date. If the name comes to you immediately, wait longer before practising it again. If you hesitate or forget it, practise it sooner.

Doing it by hand

You do not need software. You can use this simple plan:

• Try the name again on the same day, within a few hours if you can.
• Try again the next day or the day after.
• If you can still remember the name easily, wait about a week.
• Keep adding more time between tries by moving to two weeks, a month and then several months while the name stays easy.
• When you forget one, try it again sooner after a day or two. Add more time again once it becomes easy.
• Keep the written name covered until you have said your answer, then uncover it to check.
• Check easy-to-mix-up people individually. Confirm which name belongs to each person, then change the card order. Do not let “the card after Leo” become your only cue.

For a list of ten names, a dated notebook may be all the scheduling you need. Give each name a next-review date and update it after the attempt. For example, after recalling Noor easily on Monday, write Thursday beside that entry. If you miss the name on Thursday, check it and choose Friday for the next try. These dates illustrate the plan, rather than a tested rule.

For study material, the guide to remembering historical figures shows how to separate names, events and dates into cards you can check. It includes a timeline and worked examples.

The Leitner box: a physical way to manage the schedule

A Leitner box groups cards by how often you intend to review them. A name you can recall moves towards a longer wait. A missed name returns to a shorter one. Birmingham City University's revision guide recommends this way of organising flashcards.

For people, put a permitted photo or a specific encounter cue on the front and the checked name on the back. The boxes help you keep track of which cards need attention. The dated-notebook plan above is another way to manage the same task.

Box counts and intervals vary. Longer gaps are one option, and the face–name study did not find expanding schedules superior to uniform schedules in its tasks. Choose a timetable you can manage and adjust it after checking what you remember. For the complete paper setup, card template and worked review, use the Leitner box for names guide.

A four-section Leitner box. Cards move forward when the name is remembered and return to the first section after a miss.

Restart after a missed week

Keep the cards and their existing progress. A late card needs another attempt, rather than seven catch-up repetitions on the same day.

Suppose twelve cards are overdue and you have time for five. Start with people you will see soon and the names that have been uncertain. Attempt those five before reading the answers. Correct the misses and set new dates from today's review. Leave the other seven due, so you can choose the next small batch tomorrow.

Pause new names while that backlog feels too large. A repeated miss may need a better cue or a spelling check, as well as another date. If a meeting is tomorrow, check that meeting's names first and keep a short reference list available.

This is a practical restart plan for paper cards. An app may handle overdue cards differently. Do not reset an app's learning history simply to copy this example.

When a scheduler is useful

With a few names, a dated notebook or paper box may be enough. A larger list can give you several due dates to track: a new name may need attention while a familiar one can wait. Choose a tool if keeping those dates has become the difficult part. Namefinity applies the same idea to the people you save: look at a photograph, try the name, reveal it and rate your answer. The app uses that response to set the next practice date. You can keep using paper if it meets your needs.

For larger permitted lists, the photo-directory guide gives a learning plan. The name-learning guide covers ways to connect a name with the person.
