a young persons guide to Memory

All day long in school we're asked to remember things, and often it is suprisingly hard. What does science know about our memory and how can we carry out experiments on it?

How well can you remember a story? 

  1. Read the story below to the person being tested

  2. Ask them to repeat the story back to you

  3. Mark the points they remember on the test sheet.

  4. Add up their score

 

For an additional twist, add a delay between reading the story and asking your test subject to read it back to you. Do they remember less after 30 minutes compared to 5 minutes?

Test one group of people (control) normally and then test the second group with something changed. 

* Technically they measure your working memory, for more information on the difference, click here.

** This is called processing speed.
