Memory plays an essential role in everyday life, enabling us to learn about the world around us and adapt accordingly. We use memory in every moment, whether it be for remembering our clients’ first names, studying for a nursing school exam, or countless other aspects of our work and life.
Information we take in goes through the three stages of memory: encoding, storage, and retrieval. The encoding process converts information into a construct stored in the brain. Then the information is stored as either a long-term memory or short-term memory. Finally, information is available to be retrieved from storage.
There are several ways to facilitate this process, protect against memory decline, and enhance our ability to retain information. Below, we outline strategies for boosting brain health, as well as specific techniques for memorizing and recalling information.
Tips for Memory Improvement
The best way to protect and improve memory is by making good lifestyle choices: exercising regularly, limiting stress, eating healthfully, and getting enough sleep. You can also keep the mind agile by learning a foreign language or playing brain training games to improve thinking skills and short-term memory.
- Exercise regularly: Exercise is one of the best things you can do to protect your memory. Regular aerobic exercise (cardio) appears to boost the size of the hippocampus, the area of the brain involved in verbal memory and learning. Regular exercise can also help you maintain a healthy weight, reduce stress, and sleep better, all of which are related to memory.
- Limit stress: Meditation and mindfulness are also great ways to reduce stress and improve sleep. Meditation has been shown to improve episodic memory, the memory of everyday events.
- Be conscious of what you consume: Not surprisingly, what you put into your body can also affect your memory. Consuming a balanced diet that includes healthy fats and natural sugar (glucose)—and limits saturated fat, refined sugar, and alcohol—may be best for promoting long-term memory function.
- Sleep: Sleep is critical, as it plays a role in consolidating of memories. Also, a lack of sleep can impair an individual’s ability to concentrate. You can improve sleep by exercising regularly, engaging in mindfulness/meditation, limiting alcohol, and avoiding caffeine in the afternoon and evening.
8 Memory Techniques for Retaining Information
When studying for an exam, preparing a presentation, or getting ready to deliver a speech, you will likely need to memorize information.
Before you start preparing, you can do several things to set yourself up for success. Try to avoid distractions while you’re studying, plan ahead so you don’t need to cram, and take study breaks. Evidence suggests that studying shortly before going to sleep, as well as sleeping between learning sessions, can help people retain information.
Below are 8 science-backed techniques for retaining information and improving recall and memory performance.
1. Organize the information
Start by outlining the information you will need to recall. Creating a detailed, but organized outline of the information allows you to highlight and focus on important concepts.
A useful organization strategy is the chunking method, which breaks down large amounts of information into smaller, logical units that are easy to understand. For example, when learning a foreign language, you can list vocabulary words in functional groups such as household items, animals, and occupations. Chunking is a valuable tool for memorization.
2. Make associations
Creating associations by drawing on existing knowledge is another helpful way to memorize information. You can create mental images and connect with sounds, smells, and tastes to help encode memories.
The Baker/baker paradox tells us that if two individuals are to remember that someone’s last name is Baker, they are much more likely to do so if they picture the person as a professional baker (i.e., Mr. Baker wearing a chef’s hat). This is why developing a story is a powerful way to retain information. For example, if you want to remember that a client’s name is Sandy, you might picture her walking along a beach.
3. Use visual cues
Using visual tools such as concept maps, graphs, illustrations, and photos can be beneficial for learning. Graphs and charts also simplify information, making it easier to comprehend and later recall.
This method can be beneficial to visual learners, meaning individuals who better conceptualize information they can see. It’s also a great technique for presenters who can use visuals in their slide deck as retrieval cues.
Aside from being a great memory technique for retaining information, visual cues are also great for boosting spatial memory. Research has shown that visual cues have helped spatial navigation among AD and MCI patients.
4. Create mnemonics
Using mnemonic devices, such as acronyms, acrostics, and rhymes, is a good way to memorize information long-term. For example, do you remember what year Columbus landed in America? You likely do if you ever learned the rhyme, “In 1492, Columbus sailed the ocean blue.” So if you need to remember a series of numbers for work, you might consider coming up with a creative rhyme.
For more visual learners, another mnemonic device you can use is building a memory palace. A memory palace is an imaginary place (it can be a house or a familiar venue) where you can store mnemonic images. The idea behind this is you take a journey in your mind to recall the information. Some contestants in the World Memory Championship would even incorporate a story method with their memory palace.
5. Write it down
It turns out that some things are just better done the old-fashioned way. Researchers have found that writing down information by hand is more effective than typing for learning concepts. Because it takes longer to write by hand, you are naturally forced to be more selective with what you write and focus only on the key information. In fact, less is more when it comes to note taking. One study showed that the more words students wrote down verbatim when note taking, the worse they performed on recall tests.
6. Say it out loud
When you need to remember new information, it’s helpful to read it aloud. One study determined that the dual action of speaking and hearing ourselves talk helps get words and phrases into long-term memory. This study, among others, confirms that memory benefits from active involvement.
7. Engage in active recall
Testing yourself forces you to pull information from your memory. Flashcards are a great way to self-test. Studies show that retrieval practice can greatly enhance recollection than simply restudying materials. This is likely a very effective way to commit things to memory because of the significant extra effort involved.
8. Rehearse
Practice really does make perfect. Rehearse information over and over, either by writing it down or reading it aloud.
Studies suggest that spaced repetition—spacing out learning over a longer period of time—is a more effective way to memorize information than trying to “cram” a lot of information into your brain over a short period of time.
All of these memory techniques are not only backed up by science, but even memory champions can attest to their efficacy. Even if you aren’t a memory athlete, these memorization techniques can help you at school or at work. Check out our posts on effective study techniques and learning from home for further information.
