Elaborative rehearsal
Elaborative rehearsal means remembering something by thinking about what it means and linking it to things you already know. Its opposite is maintenance rehearsal, simply repeating it over and over. Repetition keeps information alive for a moment. Elaboration is what gets it into long-term memory.
The idea comes from the levels of processing view by Fergus Craik and Robert Lockhart (1972). The deeper you process something, the better you remember it. Shallow processing looks at the surface: how a word looks or sounds. Deep processing looks at meaning: what it is, why it is true, how it connects. In a well-known follow-up, Craik and Tulving (1975) showed that people remembered words they had judged for meaning much better than words they had only judged by their letters.
Maintenance rehearsal is still useful for a few seconds. Repeating a phone number until you dial it works. But it does little for next week's exam. Hours of saying a definition to yourself feel productive because the words get familiar, and familiar is easy to mistake for learned.
Elaborative rehearsal is active. Ask why a fact is true, compare it with something similar, find an example from your own life, explain it to someone else, or turn it into a question. Each link gives the memory one more way back. The broader study strategy is called elaboration. Elaborative rehearsal is the textbook name for doing it at the moment you try to remember something.
| Elaborative rehearsal | Maintenance rehearsal | |
|---|---|---|
| What you do | Link the new idea to meaning and to what you know | Repeat the item as it is |
| Processing | Deep, about meaning | Shallow, about sound or look |
| Keeps information | Into long-term memory | In short-term memory while you repeat it |
| Example | Explaining why mitochondria need oxygen | Saying 'mitochondria = powerhouse' ten times |
| Good for | Exams, understanding, transfer | Holding a number for a few seconds |
Ana needs to remember that the loop of Henle concentrates urine. Saying it 20 times fades by Friday. Instead she asks why: the loop pumps salt out, so water follows into the tissue, so the urine left behind gets concentrated. She links it to how salty food makes her thirsty. On the exam she rebuilds the answer from the logic, not from a memorized sentence.
- 1For each new fact, ask why it is true or how it works, and answer in one sentence.
- 2Connect it to something you already know well, a previous lecture or your own life.
- 3Compare it with the concept it is most easily confused with and name the difference.
- 4Explain it out loud as if to a classmate, without looking at your notes.
- 5Turn it into a question and test yourself on it again a day later.
