Rehearsal is the conscious repetition or active processing of information that keeps it in short-term/working memory and helps transfer it to long-term memory; in the Atkinson-Shiffrin model, rehearsal is the bridge between short-term and long-term storage.
Rehearsal is what you do when you repeat a phone number under your breath so you don't lose it, or when you connect a vocab word to something you already know so it sticks. In memory terms, it's the active processing that keeps information alive in short-term or working memory and (if done well) moves it into long-term memory.
The AP exam cares about two flavors. Maintenance rehearsal is rote repetition, just saying it over and over. It keeps information in working memory longer but is a weak way to build long-term memories. Elaborative rehearsal means thinking about the meaning of the material and linking it to what you already know. That deeper processing creates stronger, longer-lasting memories. In the Atkinson-Shiffrin model of memory, rehearsal is literally the mechanism that transfers information from the short-term store to the long-term store. Without it, most information in short-term memory fades within about 20-30 seconds.
Rehearsal sits at the center of the memory content in Topic 5.3 (Storing), and it threads through Topic 5.1 (Introduction to Memory) and Topic 5.5 (Forgetting and Memory Distortion). You can't fully explain the Atkinson-Shiffrin model, working memory, or why we forget without it. Rehearsal is the answer to one of the most common exam questions in this part of the course, which is how information gets from short-term to long-term memory. It also explains forgetting from the other direction. Information that never gets rehearsed never gets stored, so it can't be retrieved later. And here's the meta-level payoff: elaborative rehearsal and distributed practice are the science-backed reasons cramming with flashcards the night before works worse than spacing out meaningful review. The CED is literally telling you how to study for the CED.

Maintenance Rehearsal (Unit 5)
Maintenance rehearsal is the rote-repetition version of rehearsal. It's like treading water. You stay afloat in working memory, but you don't get anywhere. It keeps information available for the moment without building a durable long-term memory.
Encoding (Unit 5)
Elaborative rehearsal is really just deep encoding in action. When you process a term's meaning instead of its sound or spelling, you encode it semantically, and semantic encoding is the strongest route into long-term memory.
Baddeley's Working Memory Model (Unit 5)
Baddeley's model gives verbal rehearsal a home. The phonological loop is the inner-voice component where you repeat information to yourself, which is why saying a number out loud in your head keeps it from slipping away.
Distributed Practice (Unit 5)
Rehearsal answers the 'how' of remembering; distributed practice answers the 'when.' Spreading rehearsal sessions over days beats one massed cram session, so the best memory strategy combines elaborative rehearsal with spacing.
Multiple-choice questions test rehearsal in two predictable ways. First, identification: a stem describes someone repeating information to hold it in short-term memory (maintenance) or thinking about a term's meaning (elaborative), and you name the type. Second, model-based questions ask what role rehearsal plays in the Atkinson-Shiffrin model, where the answer is that it transfers information from short-term to long-term storage. On FRQs, rehearsal is a classic apply-the-concept term. The 2018 SAQ about Jackie landing the lead role in the school play is exactly this format. A strong response would explain how rehearsal (literally rehearsing her lines, ideally elaboratively and spaced over time) helps her store them in long-term memory. The grading rule is application, so naming the term isn't enough. You have to show the concept operating in the scenario.
Both are rehearsal, but they do different jobs. Maintenance rehearsal is shallow repetition (saying a Wi-Fi password over and over) that keeps information in working memory but builds weak long-term storage. Elaborative rehearsal processes meaning and connects new information to existing knowledge, which is far more effective for long-term memory. If an MCQ stem mentions 'thinking about the meaning' of material, that's elaborative. If it mentions 'keeping information in short-term memory longer,' that's maintenance.
Rehearsal is the active processing that keeps information in short-term/working memory and helps transfer it into long-term memory.
In the Atkinson-Shiffrin model, rehearsal is the mechanism that moves information from the short-term store to the long-term store.
Maintenance rehearsal is rote repetition that extends how long information stays in working memory but creates weak long-term memories.
Elaborative rehearsal involves thinking about the meaning of material and connecting it to prior knowledge, making it much more effective for long-term retention.
Without rehearsal, information in short-term memory typically fades within about 20-30 seconds, which is a core explanation for forgetting.
Rehearsal works best when it's distributed over time (spaced practice) rather than crammed into one massed session.
Rehearsal is the conscious repetition or active processing of information that keeps it in short-term or working memory and helps transfer it to long-term memory. In the Atkinson-Shiffrin model, it's the step that moves information from short-term to long-term storage.
Maintenance rehearsal is rote repetition (repeating a number over and over) that keeps information in working memory briefly. Elaborative rehearsal means processing the meaning of information and linking it to what you already know, which builds much stronger long-term memories.
Not reliably. Maintenance rehearsal mostly just extends how long information survives in working memory. To get information into long-term memory efficiently, you need elaborative rehearsal, meaning-based processing that connects new material to existing knowledge.
No, but they overlap. Encoding is the broader process of getting information into the memory system, while rehearsal is one specific strategy that supports it. Elaborative rehearsal is essentially deep, semantic encoding done deliberately.
Expect MCQ stems asking which process keeps information in working memory longer (maintenance rehearsal), which type involves thinking about meaning (elaborative rehearsal), and what role rehearsal plays in the Atkinson-Shiffrin model. FRQs may ask you to apply rehearsal to a scenario, like explaining how it helps a student memorize lines for a play.
