13 Science-Backed Ways To Improve Your Memory

13 Science-Backed Ways To Improve Your Memory

Life is made up of memories – what you have seen, heard and done; and what you’re going to do. Every bit of information you take in is only useful if you can remember it at the right time. So, how can you improve your memory?

There are many scientific theories and observations on how memories work. These theories provide us with an understanding of how feelings, routine, context and recollection affect our memories. And here are some tips backed by the scientific insights for improving memory.

1. Method of Loci

Method of Loci is a popular mnemonic technique that helps you recollect a large amount of information.[1] It works by utilizing your spatial and navigational skills as you basically envision your memories as part of a geographical entity. This is the technique that the famous fictional detective Sherlock calls as his Mind Palace.

This method is extremely useful when you are preparing for a speech or an exam. Here is how you can make use of it:

  • Visualize a space you are most familiar with. It could be your home, your favorite park or your school.
  • Construct the rooms, shelves, furniture and everything inside it in your mind.
  • Imagine yourself keeping the items you want to remember in each of the rooms or in places.
  • Next time you want to remember something, walk through room by room to recall what you placed there.

Repeating this exercise has proven to be a great way of remembering loads of information with ease.

2. Acronyms

Acronyms are proven to be very effective in memorizing a group of words. Research has shown that our brains are better at retrieving things when we associate meaning to them.[2] This is why recollecting a single meaningful word or phrase is easy compared to trying to remember a list of words.

For instance, to memorize the directions on the compass, you can use the acronym NEWS (North, East, West, and South); or, when you want to remember the Great Lakes basin, you can make us of the acronym HOME (Huron, Ontario, Michigan, Erie, Superior) etc.

Make up your own acronyms to the list of things you want to remember. all you need to do is list the things that you want to memorize and arrange them in an order such that the first letter of each word spells a real word.

3. Rhyming

There is a reason why rhymes are still a popular way to teach kids. Because our brains are good at acoustic encoding which means – breaking down sound structures.[3] We can easily remember stuff when they sound similar.

The peg method can help you out. You first need to memorize the list in the exact order given below:

one = bun

two = shoe

three= tree

four = door

five = hive

six = sticks

seven = heaven

eight = gate

nine = vine

ten = hen

After you have memorized this list, now connect the first word to bun, second word to shoe, and so on. This will help you in making a memorable connection.

Another way is to construct rhymes on the information you want to remember. For instance, if you want to remember that Mr. Jones runs a real-estate business, you can remember him with a rhyme – Mr. Jones from Homes.

Although this may seem a bit weird and funny, this method will help you in memorizing the stuff better.

4. Linking

This is a useful technique to help you stay sharp in many everyday scenarios like remembering shopping lists. This is a visualization and association technique where you associate meanings to visual imagery. However, it is important to ensure that the images stored in your mind are as vivid as possible.

For instance, if you want to remember a set of items, just link them up in a story. Let’s say that you want to remember the South England countries – Avon, Cornwall, Devon, Dorset, , Gloucestershire, Hampshire, Somerset, Surrey, and Wiltshire.

You can link all these countries in the form of a story. An AVON lady is looking for a house. She is sweating and thirsty due to high SUMMER (Somerset). In the way, she came across a giant CORN (Cornwall), but it is about to WILT (Wiltshire) in the heart. She reaches the house and knocks on the DOOR (Dorset), which is attended by the DEVIL (Devon).

She enters inside and found that a servant is seasoning the HAM (Hampshire), and everything looks extremely GLOSSY (Gloucestershire). Frightened of the whole atmosphere, the lady says SORRY (Surrey) and returns back to her path.

5. Chunking

Very few people bother to remember phone numbers by heart nowadays. But what if you lose your contacts and need a way to recollect those long numbers? This memory technique will be handy in those situations.

Chunking is basically breaking down the information into smaller pieces that are easy to remember. Start with a small number say 379372518. Break it to three chunks 378 372 518. This will help you remember better. Improve your skills every day by trying to remember more numbers this way.

6. Write It Down

Writing activates your brain cells and stimulates your reticular activating system (RAS).[4] So whenever you are trying to learn something, try writing it down. Review what you have written and test yourself.

You can also hand draw memory maps to further develop your memorization power.

7. Be Busy

Repeat all your brain exercises regularly and keep testing yourself to get better. A recent study revealed that our brain needs to be busy to keep itself fit as well.[5]

Test yourself repeatedly if you want to retain the correct information for the longest time.

Take walks or indulge in some physical activities as well. Research shows that healthy people who exercise regularly have better memories than those who don’t.

8. Give Yourself a Good Sleep

Sleeping is very much necessary if you want to be good at memory. A tired body that lacks sleep will not be able to recollect or retain information effectively. So rest well and make sure your body and mind are rejuvenated every day.

9. Eat Healthily

Try to include more vegetables and fruits into your diet to improve memory. A study conducted by Harvard medical school backs this as well. Scientists believe that the antioxidants and vitamins from vegetables and fruits help to reduce oxidative stress in the brain and help battle age-related memory issues.[6]

10. Play Video Games and Brain Training Apps

Now here is a fun way to improve memory. Playing video games may not seem the best way to study for an exam but, regular video game playing can actually improve certain memory-associated regions of the brain. Studies have shown that video games helps in total knowledge recall and can reduce dementia risk.[7]

Considering the benefits, maybe you can make brain training apps a regular pastime or something to do on your breaks.

11. Think of the Ways in Which Things Relate to You

According to a recent research, you can boost your memory considerably by contemplating why the information is important to you.[8] This signals your brain to convert the short-term memories into the long-term ones, thus helping you remember effortlessly.

12. Exercise Regularly

You might not see this coming but people who exercise daily, whether it be leisurely walking, have better memories when compared to their counterparts who do no physical activity.[9]

13. Don’t Just Memorize But Also Pay Attention to Essence

Although practice makes perfect, this might not necessarily be true when it comes to boosting memory. Scientists have found that while repetitive practice could help you in remembering things, you might miss on the bigger picture.[10]

That’s indeed true. Do you remember that one presentation when you memorized everything by heart without giving much thought to it? What happened next? Someone interrupted in between and you were not able to recall anything again!

Thus, rote repetition will not do any good. You need to complement repetition by a proper understanding of the finer details.

Bottom Line

Sharpening your memory is not rocket science. All you need to do is follow the fun and simple ways mentioned above, and eat right to boost your brain health!

What Is Unconscious Bias (And How to Reduce It for Good)

What Is Unconscious Bias (And How to Reduce It for Good)

Many conversations are being held nowadays regarding unconscious bias, but what does it really mean and how can it affect your life and the people around you? With many types of biases, it can get quite confusing. In this article, we’ll touch on cognitive bias, and then zero in on unconscious bias. Both types of biases have an immediate impact on your life because they relate to how you and others think about yourself and other people.

If you want to protect your relationships and make good decisions about other people, you need to know what these biases mean[1]. Once we have clarity about that, we can explore in more depth unconscious bias and how to address it[2].

Cognitive Bias

Let’s start with cognitive bias[3], a predictable pattern of mental errors that result in us misperceiving reality and, as a result, deviating away from the most likely way of reaching our goals[4].

These mental blind spots impact all areas of our life, from health to relationships and even shopping, as a study recently revealed[5]. In other words, from the perspective of what is best for us as individuals, falling for a cognitive bias always harms us by lowering our probability of getting what we want.

Cognitive biases have to do with judgment, not mood. Ironically, cognitive biases — such as the optimism bias and overconfidence effect — more often lead to positive moods. Of course, the consequence of falling into cognitive biases, once discovered, usually leaves us in a bad mood due to the disastrous results of these dangerous judgment errors.

Unconscious Bias

Unconscious bias is different from cognitive bias. Also known as implicit bias, it refers to unconscious forms of discrimination and stereotyping based on race, gender, sexuality, ethnicity, ability, age, and so on[6]. Despite cognitive biases sometimes leading to discriminatory thinking and feeling patterns, these are two separate and distinct concepts.

Cognitive biases are common across humankind and relate to the particular wiring of our brains, while unconscious bias relates to perceptions between different groups and are specific for the society in which we live. For example, I bet you don’t care or even think about whether someone is a noble or a commoner, yet that distinction was fundamentally important a few centuries ago across Europe. To take another example, most people in the US don’t have strong feelings about Sunni vs. Shiite Muslims, yet this distinction is incredibly meaningful in many parts of the world.

Unconscious Bias and Discriminatory Behavior

Organizations often bring me in as a speaker on diversity and inclusion to address potential unconscious discriminatory behavior. When I share in speeches that black Americans suffer from police harassment and violence at a much higher rate than white people, some participants (usually white) occasionally try to defend the police by claiming that black people are more violent and likely to break the law than whites. They thus attribute police harassment to the internal characteristics of black people (implying that it is deserved), and not to the external context of police behavior.

In reality – as I point out in my response to these folks – research shows that black people are harassed and harmed by police at a much higher rate for the same kind of activity. A white person walking by a cop, for example, is statistically much less likely to be stopped and frisked than a black one[7].

At the other end of things, a white person resisting arrest is much less likely to be violently beaten than a black one. In other words, statistics show that the higher rate of harassment and violence against black Americans by police is due to the prejudice of the police officers, at least to a large extent[8].

However, I am careful to clarify that this discrimination is not necessarily intentional. Sometimes, it indeed is deliberate, with white police officers consciously believing that black Americans deserve much more scrutiny than whites. At other times, the discriminatory behavior results from unconscious, implicit thought processes that the police officer would not consciously endorse[9].

After becoming aware that unconscious bias does exist, the next step would be learning how to recognize it in order to reduce it. I’ve outlined three crucial points to keep in mind below while further exploring the unconscious prejudice discussed above.

How to Reduce Unconscious Bias

Remember these three important points if you want to work on reducing your unconscious bias.

1. Unconscious Bias is a Systemic Issue

When we understand that unconscious bias is ultimately a systemic issue, we understand that internal cultures need to be checked and addressed first.

Interestingly, research shows that many black police officers have an unconscious prejudice against other black people, perceiving them in a more negative light than white people when evaluating potential suspects. This unconscious bias carried by many — not all — black police officers helps show that such prejudices come – at least to a significant extent – from internal cultures within police departments, rather than pre-existing racist attitudes present before someone joins a police department.

Such cultures are perpetuated by internal norms, policies, and training procedures, and any police department wishing to address unconscious bias needs to address internal culture first and foremost, rather than attributing racism to individual officers.

In other words, instead of saying it’s a few bad apples in a barrel of overall good ones, the key is recognizing that unconscious bias is a systemic issue, and the structure and joints of the barrel needs to be fixed[10].

2. There Is No Shame in Unconscious Bias

Another crucial thing that needs to be highlighted is that there is no shame or blame in unconscious bias as it’s not stemming from any fault in the individual. This no-shame approach decreases the fight, freeze, or flight defensive response among reluctant audiences, helping them hear and accept the issue.

Unconscious bias is prevalent and often doesn’t match our conscious values. Everyone holds unconscious beliefs and prejudices stemming from our tendency to categorize people into social groups. This developed naturally as a way for our ancestors to quickly size up a possible threat. Unfortunately, it doesn’t translate well in modern life.

3. It Takes a Sustained Effort to Prevent and Protect Against Unconscious Bias

After being presented with additional statistics and discussion of unconscious bias, the issue is generally settled. Still, from their subsequent behavior it’s clear that some of these audience members don’t immediately internalize this evidence. It’s much more comforting for their gut reactions to believe that police officers are right and anyone targeted by police deserves it; in turn, they are highly reluctant to accept the need to focus more efforts and energy on protecting black Americans from police violence due to the structural challenges facing these groups.

Advertising

The issue of unconscious bias doesn’t match their intuitions, so they reject this concept, despite extensive and strong evidence for its pervasive role in policing. It takes a series of subsequent follow-up conversations and interventions to move the needle. A single training is almost never sufficient, both in my experience and according to research[11].

Conclusion

The examples and points raised illustrate broader patterns you need to follow to recognize unconscious bias. Only by doing so will you be able to determine if, and what type of, intervention is needed to address it.

Unfortunately, our gut reactions lead us to make poor judgment choices when we simply follow our intuitions. Unconscious biases are systemic and need to be addressed in order to make the best decisions[12].

We need to learn about the kind of problems that result from unconscious bias. Then, you need to develop the right mental habits to help you make the best choices[13]. A one-time training is insufficient for doing so. It takes a long-term commitment and constant discipline and efforts to overcome unconscious bias, so get started now.
