Free Memory Test (5 Mins) – Short Term and Long Term

Free Memory Test

There aren't many free memory tests online, and there are none like this. Here at Practical Psychology, we have created the first and only 3-in-1 memory test that measures your short term, long term, and working memory using a quiz you can take in under 5 minutes. 

If you get confused or stuck, scroll down to learn more about each type of sub-test and it's instructions!

Short Term Memory Test

A short term memory test is very self-explanatory. The user is shown multiple digits of numbers and asked to remember them. Then, the numbers are taken off the screen and the user is asked to type the numbers they remembered in. 

This test will become more difficult as more digits are added, and digits are continuously added until the user starts forgetting the digits. According to research, the magic number most people remember is "7 plus or minus 2" items. This means an average short term memory can hold 5 to 9 digits. 

This form of memory usually doesn't last more than 18 seconds, unless rehearsed.

Long Term Memory Test

In Cognitive Psychology, long term memory is classified as information stored and retrieved for longer than a few minutes. In this memory test, we use animal images to test your visual memory by showing you 3 animals at first and asking you to recall the same 3 animals at the end. 

There are two types of long term memory: implicit and explicit. In this test, we are measuring the participants ability to recall their explicit memory with animal images.

Working Memory Tests

Working memory is the ability to use, manipulate and perform complex tasks on numbers, letters, and items. There are a few different forms of testing working memory, and this test uses 3 different variations. 

N-Back Test

An N-Back Test is a common working memory test that may be difficult to understand if you've never heard of it before. Essentially, there will be a master list of numbers you must try to memorize. The "N-Back" part comes from the test asking you what number appeared "N" numbers ago. 

For example, the test may show you "20, 34, 89" and ask you "What was the number 2 numbers ago?". The answer would be 34. Then... it will show you a new number and you have to remember the first string of numbers, plus this new number. Let's say it showed you "5". If it asked you for 2 numbers ago again, the answer would be 89.

Calculation Test

A calculation task is simple, but requires focus. First, the test will give you a few numbers. You must remember those numbers while manipulating them. For example, let's say you are given the numbers "4, 7, 9". The task is to add 4 to each number. The correct answer in this case would be "8, 11, 13".

You can increase the difficulty of a calculation test by asking the participant to perform multiple calculations, using larger numbers, or more numbers.

Rotation Task

A rotation task tests your working memory by having you perform mental rotations within your visuospatial sketchpad. Some people seem very gifted at rotating three-dimensional objections, while others struggle at this task - which shows we all have varying abilities.
