from wikiHow - The How to Manual That You Can Edit
Wouldn’t it be nice to just look at a page and never forget what was on there? What if you could never again forget a friend’s birthday? The bad news is, not everyone has a photographic memory, otherwise known as eidetic memory. Only a few actually have it, the rest rely on mnemonic devices. The good news, however, is that everyone can take steps to improve their memory, and with time and practice most people can gain the ability to memorize seemingly impossible amounts of information. Whether you want to win the World Memory Championships, ace your history test, or simply remember where you put your keys, this article can get you started.
Steps
- Convince yourself that you do have a good memory that will improve. Too many people get stuck here and convince themselves that their memory is bad, that they are just not good with names, that numbers just slip out of their minds for some reason. Erase those thoughts and vow to improve your memory. Commit yourself to the task and bask in your achievements -- it's hard to keep motivated if you beat yourself down every time you make a little bit of progress.
- Keep your brain active. Regularly “exercising" the brain keeps it growing and spurs the development of new nerve connections that can help improve memory. By developing new mental skills—especially complex ones such as learning a new language or learning to play a new musical instrument—and challenging your brain with puzzles and games you can keep your brain active and improve its physiological functioning.
- Exercise daily. Regular aerobic exercise improves circulation and efficiency throughout the body, including in the brain, and can help ward off the memory loss that comes with aging. Exercise also makes you more alert and relaxed, and can thereby improve your memory uptake, allowing you to take better mental “pictures."
- Reduce stress. Chronic stress, although it does not physically damage the brain, can make remembering much more difficult. Even temporary stresses can make it more difficult to effectively focus on concepts and observe things. Try to relax, regularly practice yoga or other stretching exercises, and see a doctor if you have severe chronic stress.
- Eat well and eat right. There are a lot of herbal supplements on the market that claim to improve memory, but none have yet been shown to be effective in clinical tests (although small studies have shown some promising results for ginkgo biloba and phosphatidylserine). A healthy diet, however, contributes to a healthy brain, and foods containing antioxidants—broccoli, blueberries, spinach, and berries, for example—and Omega-3 fatty acids appear to promote healthy brain functioning. Feed your brain with such supplements as Thiamine, Vitamin E, Niacin and Vitamin B-6. Grazing, eating 5 or 6 small meals throughout the day instead of 3 large meals, also seems to improve mental functioning (including memory) by limiting dips in blood sugar, which may negatively affect the brain.
- Take better pictures. Often we forget things not because our memory is bad, but rather because our observational skills need work. One common situation where this occurs (and which almost everyone can relate to) is meeting new people. Often we don’t really learn people’s names at first because we aren’t really concentrating on remembering them. You’ll find that if you make a conscious effort to remember such things, you’ll do much better. One way to train yourself to be more observant is to look at an unfamiliar photograph for a few seconds and then turn the photograph over and describe or write down as many details as you can about the photograph. Try closing your eyes and picturing the photo in your mind. Use a new photograph each time you try this exercise, and with regular practice you will find you’re able to remember more details with even shorter glimpses of the photos.
- Give yourself time to form a memory. Memories are very fragile in the short-term, and distractions can make you quickly forget something as simple as a phone number. The key to avoid losing memories before you can even form them is to be able to focus on the thing to be remembered for a while without thinking about other things, so when you’re trying to remember something, avoid distractions and complicated tasks for a few minutes.
- Create vivid, memorable images. You remember information more easily if you can visualize it. If you want to associate a child with a book, try not to visualize the child reading the book – that's too simple and forgettable. Instead, come up with something more jarring, something that sticks, like the book chasing the child, or the child eating the book. It's your mind – make the images as shocking and emotional as possible to keep the associations strong.
- Repeat things you need to learn. The more times you hear, see, or think about something, the more surely you’ll remember it, right? It’s a no-brainer. When you want to remember something, be it your new coworker’s name or your best friend's birthday, repeat it, either out loud or silently. Try writing it down; think about it.
- Group things you need to remember. Random lists of things (a shopping list, for example) can be especially difficult to remember. To make it easier, try categorizing the individual things from the list. If you can remember that, among other things, you wanted to buy four different kinds of vegetables, you’ll find it easier to remember all four.
- Organize your life. Keep items that you frequently need, such as keys and eyeglasses, in the same place every time. Use an electronic organizer or daily planner to keep track of appointments, due dates for bills, and other tasks. Keep phone numbers and addresses in an address book or enter them into your computer or cell phone. Improved organization can help free up your powers of concentration so that you can remember less routine things. Even if being organized doesn’t improve your memory, you’ll receive a lot of the same benefits (i.e. you won’t have to search for your keys anymore).
- Try meditation. Research now suggests that people who regularly practice "mindfulness" meditation are able to focus better and may have better memories. Mindfulness (also known as awareness or insight meditation) is the type commonly practiced in Western countries and is easy to learn. Studies at Massachusetts General Hospital show that regular meditation thickens the cerebral cortex in the brain by increasing the blood flow to that region. Some researchers believe this can enhance attention span, focus, and memory.
- Sleep well. The amount of sleep we get affects the brain's ability to recall recently learned information. Getting a good night's sleep – a minimum of seven hours a night – may improve your short-term memory and long-term relational memory, according to recent studies conducted at the Harvard Medical School.
- Build your memorization arsenal. Learn pegs, memory palaces, and the Dominic System. These techniques form the foundation for mnemonic techniques, and will visibly improve your memory.
- Venture out and learn from your mistakes. Go ahead and take a stab at memorizing the first one hundred digits of pi, or, if you've done that already, the first one thousand. Memorize the monarchs of England through your memory palaces, or your grocery list through visualization. Through diligent effort you will eventually master the art of memorization.
Simply put, memory is the mental activity of recalling information that you have learned or experienced. That simple definition, though, covers a complex process that involves many different parts of the brain and serves us in disparate ways.
Memory can be short-term or long-term. In short-term memory, your mind stores information for a few seconds or a few minutes: the time it takes you to dial a phone number you just looked up or to compare the prices of several items in a store. Such memory is fragile, and it’s meant to be; your brain would soon read “disk full” if you retained every phone number you called, every dish you ordered in a restaurant, and the subject of every ad you watched on TV. Your brain is also meant to hold an average of seven items, which is why you can usually remember a new phone number for a few minutes but need your credit card in front of you when you’re buying something online.
Long-term memory involves the information you make an effort (conscious or unconscious) to retain, because it’s personally meaningful to you (for example, data about family and friends); you need it (such as job procedures or material you’re studying for a test); or it made an emotional impression (a movie that had you riveted, the first time you ever caught a fish, the day your uncle died). Some information that you store in long-term memory requires a conscious effort to recall: episodic memories, which are personal memories about experiences you’ve had at specific times; and semantic memories (factual data not bound to time or place), which can be everything from the names of the planets to the color of your child’s hair. Another type of long-term memory is procedural memory, which involves skills and routines you perform so often that they don’t require conscious recall.
Certain areas of the brain are especially important in the formation and retention of memory:
- The hippocampus, a primitive structure deep in the brain, plays the single largest role in processing information as memory.
- The amygdala, an almond-shaped area near the hippocampus, processes emotion and helps imprint memories that involve emotion.
- The cerebral cortex, the outer layer of the brain, stores most long-term memory in different zones, depending on what kind of processing the information involves: language, sensory input, problem-solving, and so forth.
In addition, memory involves communication among the brain’s network of neurons, millions of cells activated by brain chemicals called neurotransmitters.
Stages of memory foundation and maintenance
There are three stages that the brain goes through in forming and retaining memories.Acquisition → Consolidation → Retrieval
New information enters your brain along pathways between neurons in the appropriate area of the brain. The key to encoding information into your memory is concentration; unless you focus on information intently, it goes “in one ear and out the other.” This is why teachers are always nagging students to pay attention!
If you’ve concentrated well enough to encode new information in your brain, the hippocampus sends a signal to store the information as long-term memory. This happens more easily if it’s related to something you already know, or if it stimulates an emotional response.
When you need to recall information, your brain has to activate the same pattern of nerve cells it used to store it. The more frequently you need the information, the easier it is to retrieve it along healthy nerve cell connections.
Tips for memory improvements
Do you feel that you have a poor memory? You may just have some less-than-effective habits when it comes to taking in and processing information. Barring disease, disorder, or injury, you can improve your ability to learn and retain information.Brain exercises
Memory, like muscular strength, is a “use it or lose it” proposition. The more you work out your brain, the better you’ll be able to process and remember information.
Novelty and sensory stimulation are the foundation of brain exercise. If you break your routine in a challenging way, you’re using brain pathways you weren’t using before. This can involve something as simple as brushing your teeth with your nondominant hand, which activates little-used connections on the nondominant side of your brain. Or try a “neurobic” exercise – an aerobic exercise for your brain – (see Keep Your Brain Alive Exercise) that forces you to use your faculties in unusual ways, like showering and getting dressed with your eyes closed. Take a course in a subject you don’t know much about, learn a new game of strategy, or cook up some recipes in an unfamiliar cuisine. That’s the most effective way to keep your synapses firing.
General guidelines to improve memory
In addition to exercising your brain, there are some basic things you can do to improve your ability to retain and retrieve memories:1. Pay attention. You can’t remember something if you never learned it, and you can’t learn something — that is, encode it into your brain — if you don’t pay enough attention to it. It takes about eight seconds of intent focus to process a piece of information through your hippocampus and into the appropriate memory center. So, no multitasking when you need to concentrate! If you distract easily, try to receive information in a quiet place where you won’t be interrupted.
2. Tailor information acquisition to your learning style. Most people are visual learners; they learn best by reading or otherwise seeing what it is they have to know. But some are auditory learners who learn better by listening. They might benefit by recording information they need and listening to it until they remember it.
3. Involve as many senses as possible. Even if you’re a visual learner, read out loud what you want to remember. If you can recite it rhythmically, even better. Try to relate information to colors, textures, smells and tastes. The physical act of rewriting information can help imprint it onto your brain.
4. Relate information to what you already know. Connect new data to information you already remember, whether it’s new material that builds on previous knowledge, or something as simple as an address of someone who lives on a street where you already know someone.
5. Organize information. Write things down in address books and datebooks and on calendars; take notes on more complex material and reorganize the notes into categories later. Use both words and pictures in learning information.
6. Understand and be able to interpret complex material. For more complex material, focus on understanding basic ideas rather than memorizing isolated details. Be able to explain it to someone else in your own words.
7. Rehearse information frequently and “over-learn”. Review what you’ve learned the same day you learn it, and at intervals thereafter. What researchers call “spaced rehearsal” is more effective than “cramming.” If you’re able to “over-learn” information so that recalling it becomes second nature, so much the better.
8. Be motivated and keep a positive attitude. Tell yourself that you want to learn what you need to remember, and that you can learn and remember it. Telling yourself you have a bad memory actually hampers the ability of your brain to remember, while positive mental feedback sets up an expectation of success.
Mnemonic devices to improve memory
Mnemonics (the initial “m” is silent) are clues of any kind that help us remember something, usually by causing us to associate the information we want to remember with a visual image, a sentence, or a word.Common types of mnemonic devices include:
1. Visual images - a microphone to remember the name “Mike,” a rose for “Rosie.” Use positive, pleasant images, because the brain often blocks out unpleasant ones, and make them vivid, colorful, and three-dimensional — they’ll be easier to remember.
2. Sentences in which the first letter of each word is part of or represents the initial of what you want to remember. Millions of musicians, for example, first memorized the lines of the treble staff with the sentence “Every good boy does fine” (or “deserves fudge”), representing the notes E, G, B, D, and F. Medical students often learn groups of nerves, bones, and other anatomical features using nonsense sentences.
3. Acronyms, which are initials that creates pronounceable words. The spaces between the lines on the treble staff, for example, are F, A, C, and E: FACE.
4. Rhymes and alliteration: remember learning “30 days hath September, April, June, and November”? A hefty guy named Robert can be remembered as “Big Bob” and a smiley co-worker as “Perky Pat” (though it might be best to keep such names to yourself).
5. Jokes or even off-color associations using facts, figures, and names you need to recall, because funny or peculiar things are easier to remember than mundane images.
6. “Chunking” information; that is, arranging a long list in smaller units or categories that are easier to remember. If you can reel off your Social Security number without looking at it, that’s probably because it’s arranged in groups of 3, 2, and 4 digits, not a string of 9.
7. “Method of loci”: This is an ancient and effective way of remembering a lot of material, such as a speech. You associate each part of what you have to remember with a landmark in a route you know well, such as your commute to work.
Healthy habits to improve memory
Treating your body well can enhance your ability to process and recall information.- Regular exercise
- Increases oxygen to your brain.
- Reduces the risk for disorders that lead to memory loss, such as diabetes and cardiovascular disease.
- May enhance the effects of helpful brain chemicals and protect brain cells.
- Managing stress
- Cortisol, the stress hormone, can damage the hippocampus if the stress is unrelieved.
o Stress makes it difficult to concentrate.
Good sleep habits
- Sleep is necessary for memory consolidation.
- Sleep disorders like insomnia and sleep apnea leave you tired and unable to concentrate during the day.
- Sleep is necessary for memory consolidation.
- Not smoking
- Smoking heightens the risk of vascular disorders that can cause stroke and constrict arteries that deliver oxygen to the brain.
Nutrition and Memory improvement
You probably know already that a diet based on fruits, vegetables, whole grains, and “healthy” fats will provide lots of health benefits, but such a diet can also improve memory. Research indicates that certain nutrients nurture and stimulate brain function.B vitamins, especially B6, B12, and folic acid, protects neurons by breaking down homocysteine, an amino acid that is toxic to nerve cells. They’re also involved in making red blood cells, which carry oxygen. (Best sources: spinach and other dark leafy greens, broccoli, asparagus, strawberries, melons, black beans and other legumes, citrus fruits, soybeans.)
Antioxidants like vitamins C and E, and beta carotene, fight free radicals, which are atoms formed when oxygen interacts with certain molecules. Free radicals are highly reactive and can damage cells, but antioxidants can interact with them safely and neutralize them. Antioxidants also improve the flow of oxygen through the body and brain. (Best sources: blueberries and other berries, sweet potatoes, red tomatoes, spinach, broccoli, green tea, nuts and seeds, citrus fruits, liver.)
Omega-3 fatty acids are concentrated in the brain and are associated with cognitive function. They count as “healthy” fats, as opposed to saturated fats and trans fats, protecting against inflammation and high cholesterol. (Best sources: cold-water fish such as salmon, herring, tuna, halibut, and mackerel; walnuts and walnut oil; flaxseed and flaxseed oil)
Because older adults are more prone to B12 and folic acid deficiencies, a supplement may be a good idea for seniors. An omega-3 supplement (at any age) if you don’t like eating fish. But nutrients work best when they’re consumed in foods, so try your best to eat a broad spectrum of colorful plant foods and choose fats that will help clear, not clog, your arteries. Your brain will thank you!

Memory and aging
Several factors cause aging brains to experience changes in the ability to retain and retrieve memories:
- The hippocampus is especially vulnerable to age-related deterioration, and that can affect how well you retain information.
- There’s a relative loss of neurons with age, which can affect the activity of brain chemicals called neurotransmitters and their receptors.
- An older person often experiences decreased blood flow to the brain and processes nutrients that enhance brain activity less efficiently than a younger person.
Of course, some older adults do develop more significant problems with memory that are the result of diseases such as Alzheimer’s or stroke; injury; poor nutrition; other physiological issues; or emotional problems.

Tips
- Most people’s brains are not very good at remembering abstract information, such as numbers. This is one of the things that separate those with eidetic memory from those with a great, normal memory. The key to being able to recall such things is to build associations and links that evoke the memory. This is why almost anybody with normal brain functioning can dramatically improve their ability to recall things using mnemonics. While building a memory palace, for example, actually requires that you "remember" more, by associating the thing to be remembered with other things (emotions, other memories, images, etc.) you build more mental "links" to the memory, thus making it easier to access.
- A large number of memory improvement products are available (a search on the internet will produce hundreds of such products). Most of these products actually teach you mnemonic strategies, and while some are no doubt bunk, some are legitimate.
- One easy method to help you remember people’s names is to look at the person when you are introduced and say the person’s name: "Nice to meet you, Bill."
- Try memorizing the order of a deck of playing cards. Although this may seem like a pointless task, it will allow you to discover memorization techniques that work best for you.
. Try a tray of objects (say, 10 objects). Study them for 30 seconds. Take the tray away and write down all the objects you can. Increase the number of items for more mind excercise. Or get someone else to find the objects on the tray; this makes them harder to remember and will test you more.
- Put black ink at the end of your palm to remember any important thing for the next day or for that day itself. Whenever you see the black dot, you'll remember what to do.
- Visualize whatever you have to do as part of something you see every day. For example, if you have to give your dog some medicine, visualize your dog in your fridge every time you walk past it or look inside. This will keep your dog fresh in your mind.
- Write the event or task down immediately. If you don't have a pen, one thing you can do is change the time on your watch; later on you will remember why it is set at the wrong time. You could also wear your watch upside down.
- Write in a diary or journal every day without fail. Even small issues should be written down -- this is a good way to make sure you don't miss anything.
- Leave yourself a telephone message reminding yourself of important "to do" tasks.
- Memorize your favorite song or poem until you can say it to yourself without any help. Try to do this often.
- A study by Harvard University shows that people who sleep tend to remember things better. So sleep and see how much you remember things better.
Warnings
If you notice a severe or sudden deterioration of memory, talk to your doctor immediately. Sometimes "senior moments" can be precursors to Alzheimer’s disease or dementia.While improving your ability to recall things can make a lot of tasks easier, it does not guarantee any sort of success in life.
Exercise due diligence when purchasing a memory improvement product. Find out as much as you can about how the program works, and do your own research to determine if it will work for you. Some of these products are simply scams. Be especially wary of products that promise to improve your memory instantly or with little or no effort: effective strategies to improve recall take time and practice.
While some herbal supplements that claim to improve memory may in fact work, there is no conclusive evidence that any of these are effective. Most are harmless, however, and may be worth a try, but exercise caution: some supplements can have harmful effects, and not all contain what they say they contain.
