Mnemonics are an effective strategy for memorization. They are memory devices that help learners recall larger pieces of information, especially in the form of lists like characteristics, steps, stages, parts, etc.

There are various mnemonics techniques, and today we look at some of them:

• Keyword Mnemonics

Studying a second (or third or fourth) language? Here's how the keyword method works:

• First, you choose a keyword that somehow cues you to think of the foreign word.
• Then, you imagine that keyword connected with the meaning of the word you're trying to learn.
• The visualization and association should trigger the recall of the correct word.¹

For example, if you're trying to learn the Spanish word for cat, which is gato, first think of a gate and then imagine the cat sitting on top of the gate. Even though the "a" sound in gato is short and the "a" sound in gate is long, the beginnings are similar enough to help you remember the association between gate and cat and to recall the meaning of gato.

• Chunking as a Mnemonic Strategy

Chunking or grouping information is a mnemonic strategy that works by organizing information into more easily learned groups, phrases, words, or numbers, phone numbers, credit cards, etc.

For example, memorizing the following number: 30125559467 will likely take a fair amount of effort. However, if it is chunked like this: 3012 555 9467, it becomes easier to remember.

Interestingly, chunking is one of several mnemonic strategies have proven to be helpful in improving verbal working memory in the early stages of dementia.

• Musical Mnemonics

One way to successfully encode the information into your brain is to use music. A well-known example is the "A-B-C" song.

• Letter and Word Mnemonic Strategies

Acronyms and acrostics are typically the most familiar type of mnemonic strategies.

Acronyms use a simple formula of a letter to represent each word or phrase that needs to be remembered, e.g. EPALE (Electronic Platform for Adult Learning in Europe).

An acrostic uses the same concept as the acronym except that instead of forming a new "word," it generates a sentence that helps you remember the information.

An often-used acrostic in math class is: Please Excuse My Dear Aunt Sally. This acrostic mnemonic represents the order of operations in algebra and stands for parentheses, exponents, multiplication, division, addition, and subtraction.

• Rhymes as Mnemonic Strategies

"Hey diddle diddle. The cat and the fiddle..." Can you finish the rest of this nursery rhyme?

The ability to memorize and remember nursery rhymes is often due in part to repetition and in part to rhyming. Rhyming words can be used as a mnemonic to help us learn and recall information.

• Making Connections as a Mnemonic Method

One mnemonic strategy that helps encode new information is to connect it with something else that you already are familiar with or know. This gives it meaning and makes it easier to remember..

For example, imagine that you are just introduced to someone named Jeffery. Rather than mentally zipping past his name, pay attention and think about how you can remember it.

Perhaps you notice that Jeffery is very energetic, so you can imagine him jumping around his work and connect Jeffrey with jumping. The next time you see him. you'll think, "There's 'Jumping Jeffery,' and you can say hello by name." (Don't forget to leave the word "jumping" off his name when you greet him.) 

• Peg Method Mnemonics

The peg method is an especially useful mnemonic for remembering sequenced information. If first requires that you memorize the following list in help you order the facts:

• one = bun
• two = shoe
• three= tree
• four = door
• five = hive
• six = sticks
• seven = heaven
• eight = gate
• nine = vine
• ten = hen

After memorizing this list, look over the new information that you are trying to learn. Then, connect the first word to "bun," the second word to "shoe," the third word to "tree," etc. The goal is to make a memorable connection with each new piece of information you need to memorize.

For example, let's imagine you need to learn the scientific classification system - Kingdom; Phylum or Division; Class; Order; Family; Genus; Species. Using the peg system, you'll first think of a kingdom placed on a hamburger bun. Then, you'll imagine the mathematical division sign inside a shoe. Next, you'll picture a classroom perched on a tree branch. And so on.

This method allows you to recall both the specific piece of information and the correct order in which it needs to be placed.

• The Mnemonic Linking System (Stories or Images)

The mnemonic linking method (also called "chaining") consists of developing a story or image that connects together pieces of information you need to remember. Each item leads you to recall the next item.

For example, imagine that you need to remember to bring the following things with you to school in the morning: homework papers, glasses, gym shoes, wallet, lunch money, and keys.

Using the linking system, you can think of the following short story to help you: Jack's homework papers put on their glasses and gym shoes and ran over to his wallet where his hungry keys were eating his lunch money.

If you add interesting details or humor, it often makes the information easier to remember.
