Popular Methods Used by Cognitive Champions
The brain training techniques with the most staying power tend to be the ones with real research behind them, not just aggressive marketing. Below are methods that come up often in cognitive-science literature and are used by memory champions, students, and professionals — though, as with any cognitive training, results vary and not every claimed benefit has strong evidence behind it.
1. The Method of Loci (Memory Palace)
Widely used by memory champions for decades. Place items you want to remember along a familiar mental route — your home, your commute, a school building — then recall them by mentally walking the route again. This technique draws on the hippocampus's spatial navigation systems, among the oldest and most well-studied memory circuits in the human brain. With enough practice, some people can use it to encode long lists with high accuracy, though reaching that level usually takes sustained training.
2. Dual N-Back Training
Requires simultaneously tracking two streams of updating information (visual and auditory), each with a working memory component. The task demands holding previous items in mind while processing new ones, which trains working memory directly. Some early randomised trials reported gains on fluid-intelligence tests after around 20 minutes of daily practice for 4–8 weeks, but later research has had mixed results, and many researchers now think the gains are mostly limited to the trained task itself rather than intelligence more broadly.
3. Spaced Repetition
Schedule reviews at increasing intervals — 1 day, 3 days, 1 week, 2 weeks, 1 month — to exploit the spacing effect. Reviewing at around the point where you're about to forget tends to produce a stronger memory trace than reviewing the same amount right after learning — this "spacing effect" is one of the more consistently replicated findings in memory research. Anki automates scheduling and is used by medical students to memorise thousands of facts for board exams.
4. Active Recall and the Feynman Technique
After learning something, close all materials and explain it from memory, in plain language, as if teaching a complete beginner. When you get stuck, identify the gap, return to the source, and repeat. This approach, associated with physicist Richard Feynman, overlaps with "active recall" and "retrieval practice" — techniques that a substantial body of educational psychology research rates among the more effective learning strategies available.
5. Progressive Overload in Cognitive Tasks
Borrowed from strength training: always train slightly above your current comfortable level. If a memory span game becomes easy at 6 items, force yourself to attempt 7. If a logic puzzle level is trivial, skip to harder ones. Training near the edge of your current ability, rather than well within your comfort zone, is generally considered important for this kind of practice to keep paying off. Adaptive difficulty (automatically adjusting to your level) is one popular way games try to achieve this.
How to Apply These Techniques Daily
- Morning: 10 minutes spaced repetition review (Anki or equivalent)
- Midday: 15 minutes of dual n-back or working memory game at challenge level
- Evening: 5 minutes of active recall — explain 2 things you learned today from memory
- Weekly: Practice Memory Palace encoding — memorise a new 10-item list using a route
Tools That Support These Techniques

Frequently Asked Questions
Which brain training technique has the strongest research support?
The Method of Loci (Memory Palace) and spaced repetition have the strongest research track record among these techniques — both are well documented in cognitive-science literature and have long been used by memory champions.
Do I need special apps to use these techniques?
No. Anki helps automate spaced repetition and Brain Workshop supports dual n-back, but the Method of Loci and active recall or the Feynman Technique require nothing more than your own memory and a notebook.
How long before dual n-back training shows measurable results?
Some early research trials reported gains on fluid-intelligence tests after roughly 20 minutes of daily dual n-back practice sustained for 4-8 weeks, but later studies have had mixed results, and how much benefit transfers beyond the trained task is still debated.
What is progressive overload in cognitive training?
It is the same principle used in strength training applied to the brain: always pushing slightly past your current comfortable difficulty level, such as attempting a 7-item memory span once 6 items feels easy.
Conclusion
These techniques share a common thread: they're challenging, consistent, and grounded in how memory and learning are understood to work, rather than in marketing claims. Memory Palace, dual n-back, spaced repetition, active recall, and progressive overload — applied consistently as a system — are reasonable, evidence-informed tools for building sharper recall and reasoning skills over months and years, even if the exact size of the gains varies from person to person.
