Memorization Techniques for Actors: 12 Methods and When Each One Works

Search for memorization techniques and you get lists. Twelve tips, fifteen tips, a celebrity who swears by index cards. Each one sounds fine. None of them tells you which one to use tonight, with this script, and an off-book date that isn’t moving.

That’s the real question. A one-page audition side, a two-minute verse monologue, and a full role in a two-act play are different memory jobs. The technique that saves you on one can waste an evening on another.

The short version: two techniques have the strongest research behind them, and they work on any text. Test yourself instead of rereading, and spread your sessions out instead of cramming. Everything else on this list is a way to make testing easier (first letters, flashcards, recorded cues), a way to give the words more hooks (meaning, saying them aloud, movement, places), or a way to check the result (writing it out, a reader). Below are twelve methods, what each one is good for, and where to read our full guide to it.

Start with testing and spacing

1. Test yourself instead of rereading

Cover your line, look at the cue, say your line, then check. That’s retrieval practice, and memory research backs it strongly. In a 2006 study by Henry Roediger and Jeffrey Karpicke at Washington University, students who reread a passage did better on a test five minutes later. A week later the result flipped: students who had tested themselves remembered 61 percent of it, against 40 percent for the rereaders.

The detail that matters for actors: the rereaders had read the passage about 14 times, the testers about 3.4 times, and the rereaders felt more confident. Rereading feels like learning because the words look familiar. Familiar isn’t the same as being able to produce them from a cue. Our guide to memorizing lines fast builds a whole method on this, and it’s the place to start if you only read one.

Suits: everything. Sides, monologues, whole roles.

2. Space your sessions

The same study time spread over several days holds better than one long session on the last night. A large 2008 study by Cepeda and colleagues, with more than 1,350 participants, found that the best gap between study sessions depended on how long you need to remember: for a test a few weeks away, the best gap was about 20 percent of that delay. Our rough reading for an off-book date three weeks out: review every few days, not every few hours.

In 2013, a team led by John Dunlosky reviewed common study techniques for Psychological Science in the Public Interest. Practice testing and spacing were the two that got the top rating. Rereading and highlighting were among the five rated low. Our spaced repetition schedule for actors counts the sessions back from your off-book date.

Suits: anything you have more than two days to learn.

3. Sleep between sessions

Sleep is part of spacing, and a cheap one. In a 2016 study by Stephanie Mazza and colleagues in Lyon, 40 adults learned 16 word pairs and relearned them 12 hours later. The group who slept in between needed about 3 tries to relearn the list; the group who stayed awake needed about 6. A week later the sleepers recalled about 15 pairs, the others about 11.

So a session in the evening and a quick test the next morning is a strong pairing. Playing your lines while you’re asleep is a different thing; our post on listening to lines while you sleep explains why it isn’t a shortcut.

Ways to make testing easier

A blank page is a hard test on day one. These methods give you a partial prompt so you can test yourself sooner, then take it away.

4. First-letter cues

Write only the first letter of each word, keeping the punctuation. Hamlet’s line from the Project Gutenberg edition, To be, or not to be, that is the question: becomes:

T b, o n t b, t i t q:

The letters show you the shape and the length of the line without giving you the words, so you still have to retrieve them. That makes it a halfway test. Our free first-letter memorizer turns any speech into cues like this, with no account.

Suits: long speeches, verse, and lines you keep paraphrasing.

5. Flashcards with the cue on the front

Put the cue (the end of the line before yours) on the front and your line on the back. Shuffle when you know the order, so you aren’t leaning on sequence. The cue on the front is the important part: on stage, nobody hands you your line, they hand you theirs. Our post on whether flashcards work for lines covers how to make them and when to retire them.

Suits: scenes with lots of short lines, quick back-and-forth, and lines that start the same way.

6. Record the cues and leave gaps

Record the other parts, leave a silence where each of your lines goes, and speak into the gaps. Now you can test yourself on a walk or in the kitchen. Our guide to learning lines by recording yourself covers the setup and how long the gaps should be.

Offbook does the same without the recording: realistic voices read the other parts and wait for your line, and you can hide your lines when you want a harder test.

Suits: two-handers and dialogue scenes, and anyone without a reader handy.

Ways to give the words more hooks

Testing makes memories stronger. These methods give a memory more to hold on to in the first place.

7. Learn the thought, not the string of words

Researchers Helga and Tony Noice have studied how professional actors learn roles. As the APS Observer reported, actors usually don’t learn by rote. They work out what each line means and what the character wants, and break the script into connected intentions. Students who studied by imagining they were explaining the material to someone else remembered it better than students who memorized by rote.

In practice, before you drill a speech, mark where each new thought starts and give each one a few words of summary. Learn the speech one thought at a time, then link them. Our guide to marking up your script shows how.

Suits: monologues, long speeches, and dense or old-fashioned language.

8. Say it out loud

Saying words aloud helps you remember them. In a study by Noah Forrin and Colin MacLeod at the University of Waterloo, 95 people learned words four ways: reading silently, hearing someone else read, hearing a recording of themselves, and reading aloud in real time. Reading aloud did best. Psychologists call it the production effect.

Testing out loud also keeps you honest. A 2018 study of students learning definitions, by Tauber and colleagues, found that producing the answer overtly beat answering only in your head. Those were definitions, not lines, but the lesson is the same: a line you only “think” is easy to count as right when it isn’t. Our post on out loud or in your head covers what to do when you can’t make noise.

Suits: everything, and especially text you’ll perform at full voice.

9. Move while you learn

The Noices also found that movement helps. In one of their studies, actors remembered lines they’d learned while making a fitting motion, such as walking across a stage, better than lines they’d learned standing still. They didn’t need to repeat the motion to remember. Once you have blocking, learn the lines on it: the cross, the sit, the door. Our guide to remembering your blocking shows how to tie the two together.

Suits: staged scenes, and monologues where you can give each thought a move.

10. The memory palace

Picture a route you know, your flat or your walk to the train, and place one image for each thought of the speech along it. To recall, walk the route in your head. It’s an old technique, and it can be trained: in a 2017 study in Neuron by Dresler and colleagues, men with no memory training practiced it in 40 half-hour sessions over six weeks, and their gains on word lists were still there four months later.

Word lists aren’t dialogue, though. For actors, a memory palace works best as a map of the order of thoughts in a long speech, with the exact words learned by testing. Our post on using a memory palace for lines walks through one.

Suits: the order of a long speech, a list, or a one-person show. Less useful for quick dialogue.

Ways to check the result

11. Write it out from memory

Writing your lines out from memory, then checking against the script, is a slow, strict test. You see every dropped “and” and swapped word, which is why it suits text that must be word-perfect. Copying from the page is a different exercise: it isn’t a test, because the answer is in front of you. Our guide to whether writing out lines helps covers the difference, and our post on how to stop paraphrasing picks up from there.

Suits: verse, heightened text, and the speech you keep getting nearly right.

12. Run it with a reader

Knowing the words alone in your room isn’t the same as saying them when another person hands you the cue at their own pace. Before the off-book date, run the scene with someone who’ll hold book and give you exact line notes. Our guide to running lines with someone covers how to ask and what to ask for, and our free run lines online tool lets you try it on a classic scene right now.

Suits: any scene, as the final check.

Which technique for which text

Put them together in one plan

Here’s how the methods fit together over a week or two. Adjust the days to your calendar; the order is what matters.

• First session: read the scene for story, mark the thoughts, and say each one in your own words.
• Same session: learn one thought at a time out loud, then test it against the cue with the line covered.
• Next morning: test cold before you look at the page. Relearn only what’s gone.
• Every few days: test again, using first-letter cues for anything shaky, then take them away.
• Once you have blocking: run the lines on the moves.
• Before the off-book date: write out the hardest speech from memory, then do a full run with a reader or recorded cues.

Questions actors ask

What is the best memorization technique?

Testing yourself, spread over several days. In the 2013 review of study techniques led by John Dunlosky, practice testing and spacing got the top rating, and rereading got a low one. For lines, that means covering your line, saying it from the cue, and checking, in short sessions with sleep in between. The other methods on this list make that testing easier or richer.

How do actors memorize so many lines?

Largely by understanding them. The Noices’ research found that actors usually work out what each line means and what the character wants, instead of learning the words by rote. Repetition still matters, but it’s repetition of the scene with its thoughts, cues, and moves, over many rehearsals, not one long cram.

Which memorization technique works for long speeches?

Split the speech into thoughts and learn one at a time out loud, with first-letter cues as a halfway step. A memory palace can hold the order of the thoughts. Then write the speech out from memory to catch the small slips. Our guide to memorizing Shakespeare covers verse in particular.

How many times should I repeat a line to memorize it?

There’s no magic number, and counting rereads is the trap. In the Roediger and Karpicke study, students who read a passage about 14 times remembered less a week later than students who read it about 3.4 times and tested themselves. Count tests from the cue instead, and stop a session once you’ve got a line right from memory a couple of times. Come back to it on another day.
