If this happens a lot, you might feel like you’re losing your memory!

But don’t worry! There are a large number of memory number tests to see whether your memory is serving you well.

In this article, I’ll first explain what working memory is, and how a memory number test can help you solve any memory problem you may have.

I’ll also introduce you to a powerful technique to boost your brainpower and help prevent memory loss.

Here’s what this post will cover:

Ready to test your working memory? Let’s get started.

What is Working Memory?

Let’s say you’re driving down a street, and all of a sudden, you get rear-ended by another vehicle!

As the car speeds off, you just have a few seconds to look at its license plate, identify the make and the model – all the while you’re trying to locate your phone or notepad.

Then you have to write down all the details (time, location, car color, license plate, etc.) before you forget.

And later that day, you piece together all that information and form a coherent story that you can tell your friends, family and the police, of course.

Cars parked along a tree-lined street.

What you did there was use your ‘working memory’.

Working memory is the function of short-term memory that lets us store information, as well as manipulate the data in order to perfect complex tasks.

In his 2013 Ted Talk, educational psychology professor, Peter Doolittle broke down working memory into four parts:

  1. Storing the immediate experience into short-term memory (experiencing the accident)
  2. Reaching back into long-term memory (identifying the car)
  3. Processing the experience and memories together (making sense of what just happened)
  4. Applying the meaning from this process to the task (writing it down/telling the story)

If you have a good working memory, you’ll be able to process the information better and pick out what details are crucial to the story, and block out all the rest.

So is it any wonder that those with good working memory are good storytellers?

Not just that, they also score higher at standardized tests. And here’s the kicker: people with high-functioning working memory also have higher general intelligence!

In fact, neuropsychologist Tracy Alloway thinks working memory tests can gauge our cognitive skills better than IQ tests.

What’s The Difference Between Working Memory And Short-Term Memory?

They might seem similar, but there is a key difference.

In 1968, the Atkinson-Shiffrin model described short-term memory as the ability to merely store limited information in your brain temporarily for a few seconds or minutes.

However, in 1974, Alan Baddeley & Graham Hitch presented an accurate model of short-term memory.

The model says that working memory is the ability to not just store limited information, but to process it, make decisions, and use it to solve problems.

We need to understand why they’re important.

Since working memory is such an important part of our lives, we make an effort to keep it sharp. And we can do that by regularly assessing its health using cognitive tests.

Why Should You Test Your Memory Capacity?

It’s not that difficult to remember a 5-9 digit phone number that has just been recited, right?

But it becomes harder when you need to remember a barcode with more than 10 digits.

Why is that?

According to psychologist George Miller, the ‘magical’ number of items (or digit span) that you can hold in your short term and working memory is 7±2.

Chances are that your working memory capacity might be the same.

But how do you know for sure?

It’s important to test your memory capacity, to know the limitations of your memory span. When you have a clear picture of your memory capacity, you can work towards improving it.

However, this isn’t the only reason why you need to test your working memory capacity.

If you’re concerned that you’re being increasingly forgetful recently, you can use cognitive tests to rule out any memory disorders.

Through these cognitive tests, you can try different improvement methods, and test which techniques help you get a higher score.

This way you’ll be able to figure out the best memory improvement technique for you!

Also, memory tests coupled with memorization techniques can even boost your long-term memory retention too!

What Are Memory Tests?

Memory tests are short exercises that help you figure how good your memory really is.

Over hundreds of years, psychologists and neuroscientists have created tests to identify cognitive impairment in patients after a traumatic brain injury. These tests allow them to give their diagnosis after a comprehensive evaluation.

But now, you don’t need to show signs of memory impairment to try out these tests. There are tons of memory testing tools that can be used by anyone online.

3 Types Of Memory Tests

Let’s take a quick look at the different types of memory tests.

1. Short-Term Memory Test

Objects in your short-term memory are generally stored for around 20-30 seconds.
So these tests are generally straightforward.

You’ll have to memorize a list of numbers, names, or objects in a short period of time.

A table of memory number test words.

Then, you will be asked to write down what items you saw, and don’t worry, it doesn’t always have to be in order.

2. Long-Term Memory Test

Long-term memory refers to storing information in your brain for more than a few minutes.

In a long-term memory test, you’ll be shown a few objects, numbers, letters, or words, and be asked to recall them after 5 minutes or even more.

3. Working Memory Test

Having a good working memory makes it easier to deal with our day-to-day.

We use working memory when we’re driving, writing essays, studying, following a recipe, learning a language, and more.

Working memory tests are slightly more complicated than short-term memory tests. Here, you need to not only memorize and recall information, but you need to do some arithmetic and logical problem solving too.

To take a look at an example of these tests, let’s get back to Professor Doolittle’s TED talk.

He asks the audience to remember 5 words: ‘Tree’, ‘Highway’, ‘Mirror’, ‘Saturn’, ‘Electrode’.

Then without a beat, he asks them to solve a basic multiplication problem.

After that, he asks them to take out their left hand, and count up to 10 on their hand.

And finally, he asks them to recite the last 5 letters of the alphabet backward.

After this gauntlet of tasks, he asks the audience whether they still remember all the words – only half of them did!

If only they visualized the words as images, they would have been able to recall the words effortlessly!

Let’s take a closer look at other examples of working memory tests, specifically working memory number tests.

What Are The Different Types Of Working Memory Number Tests?

Here are some tests that you can practice to improve working memory, so you can improve the quality of your life too.

A. Sequencing Test

This test is based on the Wechsler Memory Scale which is used to test different memory functions in adults. The sequencing assessment is used to test your brain’s response time and processing speed — both of which are important parts of working memory.

Here’s how it works:

Step 1:
You see a set of 2 balls with different numbers appearing on the screen in a sequence.

Step 2:
You quickly memorize the order of appearance.

Step 3:
You recall and reproduce the set of numbers in the correct order.

Step 4:
Now you see a set of 3 balls, and you need to memorize the order.

Step 5:
This number of balls increases every round until you get it wrong.

B. N-back Test

N-back is one of the most popular working memory tests. It requires you to hold objects in memory and retrieve them when needed.

Here’s how the n-back test works:

Step 1:
You are shown a string of numbers, for example: ‘23’, ‘56’. ‘92’.

Step 2:
You are asked what number you saw ‘n’ numbers ago, for example: ‘2’ numbers ago.
Here the answer would be 56.

Step 3:
You are shown a new number, for example ‘88’. So now the string of numbers in your head should be: ‘23’, ‘56’, ‘92’, 88’.

Step 4:
You are again asked what number you saw ‘n’ numbers ago, maybe this ‘n’ can be 4. Here the answer is 23.

Step 5:
Another new number is added, and another question is asked. This continues until you’re no longer able to keep track of the numbers.

Want to make it even more complex?

Instead of one string, you can have 2 strings of numbers to memorize. One can be shown visually, and the other sequence can be heard, thereby using 2 stimuli.

Each round new numbers are added to the sequences. This is called the ‘dual n-back test’.

This seems more effective, as a present study suggests practicing the dual n-back test, can boost working memory by 30%!

C. Digit Span Test

This is a great memory testing tool for children and older adults alike.

Here’s how the digit span test works:

Step 1:
A sequence of numbers flashes on the screen in quick succession.

Step 2:
You need to input the sequence of numbers in order, until there’s an error.

To make the digit span test even more challenging, you might be asked to input the sequence in reverse.

The digit span task can be used to test your verbal working memory. An examiner can read out a list of numbers, and you would have to repeat the numbers in the correct order.

It’s also used by researchers to study patients with cognitive impairment and memory loss. Now let’s look at the factors responsible for working memory loss.

What Causes Working Memory Loss?

Turns out old age isn’t the only factor that can cause memory impairment! There are quite a few health and lifestyle-related reasons responsible for memory loss and cognitive decline.

Let’s look at some of them.

1. Dementia in Older Adults

Patients with Lewy body dementia show greater signs of memory impairment as compared to patients with Alzheimer’s disease. In fact, memory loss is a major symptom of Lewy body dementia, as well as vascular dementia.

2. Parkinson’s Disease

This disease has been linked to spatial WM impairment (memory required to navigate through an environment).

3. ADD/ADHD in Kids and Adults

Attention deficit disorder can cause deficits in working memory in kids and adults. Those with ADD and ADHD have difficulty focusing, organizing information, recalling information — which are all key functions of working memory.

To help reduce this cognitive impairment in children with ADHD, a few working memory training techniques are undergoing clinical trials.

4. Depression

Depression is known to affect working memory capacity and cause difficulties in concentration. Bipolar affective disorders can also be responsible for the impairment of working memory.

5. Stress

Stress’s relationship with working memory is a bit complicated. While stress does reduce our response time, it can cause us to make more mistakes than usual.

6. Lack of Sleep

According to a 2007 study, sleep deprivation not only impairs attention and working memory, it also affects our long-term memory and decision making abilities.

Anxious that any of these factors might be affecting your memory?

We have good news! You can weaken their grip on your memory with the help of a few easy techniques.

3 Memorization Techniques To Help Sharpen Your Memory

Even if we’re healthy or don’t have any pre-existing disease, we still might struggle with our memory abilities.

Why is that?

The answer is pretty simple: It’s a lack of memory exercise!

I don’t mean playing brain games on your smartphone. Playing exercise games is not always brain exercise. And a 2017 study has proved studies have shown that they don’t even work!

Don’t worry, here are some memory exercises that actually do the job.

1. Number Brain Exercises

These exercises can be used to boost logical thinking and concentration, and the best part is that it’s fun!

Wooden puzzles sit on a table. Brain games can help boost your memory (just not the ones on your smartphone).

Here’s how it works:

Pick any 3-digit number.

Add 3 the number 3 times. And then minus 7 from the result number 7 times.
Repeat this process 5 times, and then pick another 3-digit number.

Too easy?

Try this exercise with a 4-digit number, and add or subtract larger numbers.

This exercise is a great workout for your working memory, because of the amount of information you need to hold in your brain.

2. Repeat and Recall

Everybody likes a good listener, right?

This exercise can not only improve your working memory, but can also help you be more present ‘in the moment.’

Try this:

When someone is talking to you, focus on the words being spoken and silently repeat and speak them in your mind.

This exercise is a super-effective way to boost your cognitive function and you’ll never forget a thing your friend or partner said to you, ever!

3. Memory Palaces

This is the ultimate memory training exercise there is. Creating a memory palace challenges your visual and spatial memory.

Not only that, it unlocks your episodic memory, semantic memory, procedural memory – so you can store information in your long-term memory faster and more efficiently.

How does it work?

The basic idea behind a memory palace is to associate pieces of data with a location that you know well. For example: your bedroom.

When you close your eyes, you can picture your room well you know where the furniture is placed, the color of the objects, and where your stuff is placed.

The memory palace technique requires you to associate information with areas of that room.

As you mentally walk through the location, you can place information you wish to memorize in specific areas of the room. When you want to retrieve the information, you have to follow the mental route, and access it.

Sounds interesting, doesn’t it? Check this out:

You can use memory palaces to memorize an entire monologue, or learn a new language.

Or use it to pull off impressive stunts like memorizing every American president!

The choice is yours.

A Memory Palace is a powerful tool that you can use for a lifetime. Once you’ve created and mastered one, you can make dozens more to improve your life.

Then you can go on to add other tools, like the Dominic System for memorizing numbers.

Is a Memory Number Test for You?

A memory number test doesn’t necessarily improve your working memory right away. However, they are an important tool to help you gauge your memory capacity.

Knowing is just half the battle, right?

You then need to practice many memory exercises simultaneously and see which methods help you ace the memory number tests. And the better you get at these, the more razor-sharp your working memory gets!
