Memory techniques
Memory techniques are strategies and devices that make information easier to encode and recall, such as mnemonics, the method of loci and chunking.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
The main types
Several families of memory technique are widely used. Mnemonics encode information using acronyms, acrostics, rhymes or songs — such as a phrase whose initials cue an ordered list. The method of loci, or memory palace, places items to be remembered at locations along a familiar route, so a mental walk retrieves them in order. Chunking groups individual items into larger meaningful units, as when a long number is broken into blocks. Visualisation and association turn abstract material into vivid mental images linked to existing knowledge.
Why they work
Most memory techniques work by imposing meaning, structure or imagery on material that is otherwise arbitrary and therefore hard to recall. Human memory retains organised, meaningful and vivid information far better than isolated, abstract facts. By tying new material to a familiar route, a memorable image or an existing pattern, these techniques give the mind extra retrieval cues. Chunking additionally reduces the load on working memory by treating several items as one, which is why grouping makes long strings easier to hold and recall.
Where they help and their limits
Memory techniques are especially useful for material that must be recalled in a fixed form or order — vocabulary, lists, sequences, names, formulae. They are less central to deep conceptual understanding, which depends more on explanation and reasoning than on recall devices. For lasting retention, memory techniques are best combined with retrieval practice and spaced repetition: a mnemonic helps you encode information memorably, while spaced self-testing ensures it stays accessible over time rather than fading after first learning.

- Why they work: add meaning, structure or vivid imagery to arbitrary material
- Best for: lists, sequences, names, vocabulary and formulae
Common misconceptions
What people often get wrong
Often heard: Memory techniques replace the need to understand material.
Actually: Mnemonics and similar devices aid recall of facts and sequences, but they are not a substitute for understanding. Deep comprehension depends on explanation and reasoning. Memory techniques work best alongside understanding, helping retain information that must be recalled in a particular form.
Often heard: A good memory is something you are born with and cannot improve.
Actually: Memory performance for many tasks can be substantially improved with technique and practice. The method of loci and similar strategies are the basis of competitive memory feats by people with ordinary memories. The skill lies in the methods, which can be learnt.
Often heard: The method of loci only works for memory-competition stunts.
Actually: The method of loci is a practical, general technique for remembering ordered information — speeches, lists, steps in a process. Although memory athletes use it dramatically, the same approach helps ordinary learners recall any sequence by attaching items to a familiar route.
