Distributed practice is a memory strategy where you spread study sessions out over time with breaks in between, instead of cramming everything into one session (massed practice). The spacing leads to stronger encoding and better long-term retention.
Distributed practice is studying in multiple shorter sessions spread across days or weeks, rather than one marathon session the night before a test. Reviewing material in spaced-out chunks gives your brain repeated chances to encode the information, and each return to the material strengthens the memory trace.
The reason it works is the spacing effect. When you let some forgetting happen between sessions, your brain has to work harder to pull the information back, and that effort makes the memory more durable. Cramming (massed practice) can feel productive because the material seems fresh, but that fluency fades fast. Distributed practice trades short-term comfort for long-term retention, which is exactly what storage in long-term memory requires.
Distributed practice lives in Topic 5.3 (Storing), where the focus is on how information gets moved into and kept in long-term memory. It's one of the most reliable, research-backed strategies psychologists have identified for durable storage, so it shows up both as exam content and as advice you can actually use to study for the exam itself. It also pairs naturally with retrieval practice in the CED's coverage of effective learning strategies. On the 2026 exam, the Evidence-Based Question asked for an argument about what strengthens a person's ability to retrieve recently learned information, and distributed practice is exactly the kind of source-backed evidence that question rewards.

Spacing Effect (Unit 5)
The spacing effect is the finding; distributed practice is the strategy built on it. Research shows spaced exposures produce better retention than crammed ones, and distributed practice is how you put that finding to work.
Retrieval Practice (Unit 5)
These two are the power couple of effective studying. Distributed practice tells you WHEN to study (spread it out), and retrieval practice tells you HOW (test yourself instead of rereading). Combining them, like doing spaced self-quizzing, is the strongest evidence-based combo.
Long-Term Potentiation (Unit 5)
LTP is the biological reason spacing works. Repeated activation strengthens synaptic connections over time, so revisiting material across multiple sessions literally builds stronger neural pathways than one cramming session can.
Interleaving (Unit 5)
Interleaving means mixing different topics or problem types within a study session instead of blocking one at a time. It's a separate strategy from spacing, but the two often travel together because mixing topics naturally spreads each one out.
Multiple-choice questions often test distributed practice as a comparison, asking which strategy produces better long-term retention or which research design could show that distributed practice beats massed practice (for example, an experiment with one group studying in spaced sessions and another cramming, then comparing recall later). You should be able to define it, contrast it with massed practice, and explain why spacing improves storage. It's also strong FRQ material. The 2026 EBQ asked for a defensible claim about what strengthens retrieval of recently learned information, and distributed practice is a textbook piece of evidence for that kind of argument. If a scenario describes someone reviewing flashcards for 20 minutes a day over two weeks versus pulling an all-nighter, name the concept and predict who remembers more.
These are opposites, and the exam loves contrasting them. Massed practice is cramming, one long study session right before you need the information. It can produce decent short-term performance, which is why it feels like it works. Distributed practice spaces the same study time across multiple sessions and consistently wins for long-term retention. Same total hours, very different outcomes.
Distributed practice means spreading study sessions out over time with breaks in between, rather than cramming everything at once.
It works because of the spacing effect, where spaced exposures to material produce stronger long-term retention than the same amount of study done in one session.
Massed practice (cramming) can boost short-term performance, but distributed practice wins almost every time for long-term memory.
Distributed practice answers WHEN to study, while retrieval practice answers HOW to study; combining them is the most effective evidence-based approach.
On the AP exam, be ready to identify distributed practice in study scenarios and to use it as evidence in arguments about what strengthens memory retrieval.
Distributed practice is a learning strategy where you space study sessions out over time with breaks in between, instead of cramming. It's covered in Topic 5.3 (Storing) as one of the best-supported ways to build long-term memory.
Not quite, though they're closely linked. The spacing effect is the research finding that spaced study produces better retention than massed study, and distributed practice is the study strategy you build from that finding.
Only for very short-term performance. Cramming can get information into memory for a test the next morning, but it fades fast. For long-term retention, which is what cumulative exams like the AP test demand, distributed practice consistently outperforms massed practice.
Distributed practice is about timing, spreading sessions on the same material across days or weeks. Interleaving is about content, mixing different topics or problem types within a single session. They're separate strategies that work well together.
Break content into chunks and review each one in short sessions spread across multiple days, ideally combined with self-testing (retrieval practice). For example, 25 minutes of flashcard quizzing per unit every few days beats a 5-hour review session the night before.
