Would you like to be able to memorize a whole book? What about those boring declination tables?

Silly question. Who wouldn’t?

One way or the other, you have heard of fantastic memory feats of mnemonists – memorizing decks of cards or thousands of digits. And all this seemingly effortlessly.

Mnemonics have the power to stimulate the imagination. They definitely stimulated mine.

This dream, the dream of being able to memorize anything I want, triggered the chain of events which made me embark on a bumpy journey/

Destination? To discover the actual effectiveness and usefulness of mnemonics and master my memory.

Effectiveness and Usefulness Of Mnemonics In Learning – My First Experience

What Are Mnemonics?

Before we move on, it’s good to explain what mnemonics are quickly. In short, mnemonics are devices to aid our overburdened memory.

They are used to facilitate efficient encoding by associating new information with the knowledge which is already stored in your long-term memory (Johnson & Weber, 2006 as cited in Gibson, 2009).

Probably the most common mnemonic device the so-called keyword method coined by Atkinson (1975). It is used to make meaningful auditory and imagery links to remember a word.

For example, if you want to remember that “to buy” in Spanish is “comprar,” you might create a vivid picture of a man who compares prices of products before the purchase. Not that complicated, right?

Let’s see now what science has to say about mnemonics.

Effectiveness and Usefulness of Mnemonics in Learning – an Overview of the Scientific Literature

There is a large body of research about mnemonics. However, probably the most interesting study up-to-date was led by Kent State University professor John Dunlosky and released in April 2013 by the Association for Psychological Science.

In a comprehensive report, the group of authors carefully examined ten learning tactics and rated them from high to low utility based on the evidence they’ve gathered.

If you are expecting mnemonics to be among the most useful strategies, don’t hold your breath. They didn’t even come close to the top of the list.

” According to the authors, some commonly used techniques, such as underlining, rereading material, and using mnemonic devices, were found to be of surprisingly low utility.“

Clearly, people with untrained memory would not be able to come close to these results. Still, the report says clearly – mnemonics might not be the best use of your time.

Of course, I must be perfectly honest with you. There are a lot of studies which show that using mnemonics might be very beneficial for (among others):

• memorizing names
• learning vocabulary
• learning math

What’s even more important, some studies showed memory improvement with students with disabilities, as described by Fulk (1994) and Bulgren et al. (1994).

And these are just a few of them and they all state clearly – mnemonics are statistically more effective.

Effective than what?! And why didn’t I include these studies here then?

Problems With Studies On The Effectiveness and Usefulness of Mnemonics in Learning

Having read dozens of studies on mnemonics, I can divide the flaws of these studies into the following categories:

a) Statistical sample is not representative

Do you know how to recognize bad, bullshit science at first glance? Look at the sample.

To generalize, any number below 100 participants means that researchers just threw your tax money into the gutter.

b) Control groups suck

Do you know what the usual control group against mnemonics-using students is? Rote learning students.

Ugh, it’s like watching some bizarre boxing match. “Ladies and gentlemen, let’s gather around to enjoy this very duel – a retarded shrimp vs. quite an ordinary shrimp.”

c) Laboratory settings

99,9% of these studies are conducted in laboratory settings. And there is quite a yawning gap between research in areas of everyday memory (i.e., field research) and lab-controlled research.

The Hawthorne effect is one of the things which comes to mind.

“A type of reactivity in which individuals modify or improve an aspect of their behavior in response to their awareness of being observed“

It’s tough to generalize such results to other settings

What’s more, so-called low ecological validity comes into play. The laboratory is clearly an artificial situation. People are directed by an ‘experimenter’ in a psychological experiment. They are removed from their natural social settings and asked to memorize different sets of data.

This is a very unusual experience that raises the question – how do this novel experience and settings really affect their behavior and memory?

Still, lab research is better than no research at all.

d) Time horizon

Most studies are conducted over a relatively short period. It’s rarely spread over more than 3-4 weeks. As you will soon read, this is why most studies prove the effectiveness and usefulness of mnemonics.

e) Nature of the tasks

Are mnemonics useless?

Am I saying that mnemonics are useless then? Not at all. They can be insanely useful.

But you must understand what they are and what they aren’t. I quoted the excerpt from John Dunlosky’s report for two reasons:

• 1) It tested different learning strategies against one another.
• 2) More importantly, it examined the effects of those strategies in LONG-TERM learning.

And this is what mnemonics are not.

They are not a suitable tool for long-term learning.

At least not in the form they are usually presented.

If you are not pressed for time, you can get by without any problems without using mnemonics.

They are also not a panacea for all your memory problems. It is just another tool in your learning arsenal.

If you have ever read anything by any author, who promotes/sells anything mnemonics-related, you might find it hard to believe. Don’t worry. I also felt disillusioned. And I had good reasons.

Effectiveness and Usefulness of Mnemonics in Learning – My Experiments 

Picture by: Vlad

Inevitable drop in recall rate always came after more than four weeks.

And this is precisely why most scientific studies seemingly prove the effectiveness of mnemonics. They test them in labs in short periods.

Once again, I would like to stress that mnemonics can be immensely useful. Useful both for recalling random information as well as helping you achieve high levels of expert performance. Just not for long-term learning.

Read on, and I will show how they can be utilized best. But first, to have a full picture of what you’re dealing with, take a look at the limitations of mnemonics.

Limitations And Disadvantages Of Mnemonics

• Gruneberg (1998) argues that the keyword method, in general, is inferior to rote learning in the longer-term retention of vocabulary.
• “Campos and Gonzalez (2003) attribute ineffectiveness of the keyword method to participants ‘lack of training. They investigated in four experiments the effectiveness of the mnemonic keyword method using two groups of adults and adolescents. In all the experiments, the rote method was more effective than the keyword method for both adolescents and adults.”
• Some people (especially adults) are reluctant to create vivid images and crazy stories.
• Some people (especially adults) are unable and/or unwilling to resign from using previously learned strategies.
• Using mnemonic devices for memorizing words is time-consuming (especially at the beginning).
• Using mnemonics requires more effort (especially at the beginning) than rote-learning.
• Mnemonics don’t guarantee understanding.
• Learning with mnemonics lacks context.

So if mnemonics are not an excellent way for long-term learning, what are they good for?

How Mnemonics Affect Your Short-Term Memory

Short-term memory has three key aspects:

• 1. limited capacity (only about 7+-2 items can be stored at a time or 3-4 chunks)
• 2. limited duration (storage is very fragile, and information can be lost with distraction or passage of time)
• 3. encoding (primarily acoustic, even translating visual information into sounds).

And here is where the true power of mnemonics lies.

Mnemonic devices allow you to boost all these three aspects of your short-term memory significantly.

It might not seem like a big deal, but it has tremendous implications for your (language) learning.

Why?

Because short-term memory is a necessary step toward the next stage of retention – long-term memory, you can treat short-term memory as a bottleneck of your learning. After all, if you can’t commit some information, even just for a few seconds, to your memory, how are you supposed to learn?

Some researchers claim that working-memory capacity reflects the efficiency of executive functions. In other words, the ability to maintain and manipulate information in the face of distractions and other irrelevant information. ( Engle, R. W., September 1999).

That’s why the best way to think about mnemonics is to treat them as a relatively long-lived external memory with huge capacity.

I will get to the most effective use of mnemonics in a second. First, I want to demonstrate something. Let’s take a look at prodigies.

The Short-Term Memory Of Prodigies

Studies on the prodigies who reached professional-level performance in their domain (e.g., art, math, music) by the age of 10 show something very interesting.

When Psychologist Joanne Ruthsatz and violin virtuoso Jourdan Urbach administered an IQ test to nine prominent child prodigies (…) there were a wide range of IQ scores among the eight prodigies (from 108 to 147), and their cognitive profiles were uneven.

It turned out that the key to understanding their rapid learning in their domain was not their global intellectual functioning.

Most strikingly, every single prodigy in their sample scored off the charts (better than 99 percent of the general population) in working memory — the ability to simultaneously store incoming information while processing other information.

So how can you approach these levels of intellectual functioning?

Key Information Needed to Understand How To use Mnemonics Effectively

1) We learn best by doing

2) Calling information to mind strengthens it and helps in future retrieval

3) Understanding the difference between procedural and declarative knowledge.

According to Cohen and Squire (1980):

Procedural knowledge involves “knowing how” to do things. It includes skills, such as “knowing how” to play the piano, ride a bike; tie your shoes and other motor skills. It does not involve conscious thought (i.e. it’s unconscious – automatic). For example, we brush our teeth with little or no awareness of the skills involved.

Declarative knowledge involves “knowing that”. Knowing names of plants , dates, formulas – it’s all part of your declarative knowledge. Recalling information from declarative memory involves, so called, effortfull recall – i.e. information has to be consciously brought to mind and “declared”.

Knowing these things can help us stew perfect learning mix:

• 1) Gather information 

It doesn’t matter whether you want to learn a language or how to master persuasion strategies. Gather the knowledge needed to achieve your goal.

• 2) Memorize it with mnemonics

As I have written before, mnemonics can be treated as an extension of your short-term memory. Place as much information as you can on this external “hard-drive.”

• 3) Start practicing right away

You know the theory of how to play the piano or how to program. It’s high time you started putting your knowledge into practice. Try to use as many pieces of information from your memory as you can.

Because every time you bring one of them to your mind, the magic happens. You start creating and strengthening neural networks responsible for the given action.

Repeat this action a sufficient number of times, and you will automate it. From that moment on, you will be able to perform it subconsciously and with minimal effort.

Let’s see how you can use it in language learning.

Effectiveness and Usefulness of Mnemonics in Language Learning

Picture by: Shannon Kokoska

When I launched my Czech mission, I already had a rough plan of how to achieve my desired level in record time. This is more or less what I did:

• 1) I got familiar with grammar
• 2) I memorized basic declinations and conjugations with mnemonics
• 3) I memorized about 50 essential words with mnemonics
• 4) I started producing a lot of sentences by talking to myself and by using the words and mentioned above 
• 5) I “rinsed and repeated” points 2-4. Each time I increased the number of words and grammar constructions

Of course, there was also listening and reading practice. If someone asks me what the quickest way to learn a language with mnemonics is, I show them this plan. I also tell them to use ANKI or combine those strategies.

Either way, since learning with mnemonics lacks context, I would avoid using it for language learning unless you can produce lots of sentences with the vocabulary you have memorized this way,

Since we have established that mnemonics can be treated as your external memory, take a look at other practical applications of mnemonics!

(Other) Practical Applications Of Mnemonics

Mnemonics are useful whenever you need to memorize a lot of information on the fly and remember them for at least a couple of hours.

That’s why you can use them (among others):

• During parties and meetings to memorize names and information about other participants
• during last-minute panic before the exam or company presentation to make sure that the data stays in your memory!
• During speeches.
• to impress your wife and show her that “you don’t need no damn shopping lists” to remember what you should buy
• to memorize random information which emerges during conversations

And so on. I think you got it!
