Learn: how memory works
Memory is not one system. It splits by how long it holds information and by what kind of information it handles, and each part can succeed or fail on its own. These guides explain the basics plainly, then point you to the test that measures each part.
Guides
How memory works
Encoding, storage, and recall, why you forget, and what the forgetting curve means for learning.
Types of memory
Sensory, short-term, working, and long-term memory, plus visual, verbal, and spatial. What each does and which test measures it.
Memory test for dementia
What an online memory test can and can't tell you, how SAGE, Mini-Cog, MoCA and MMSE work, and when to see a doctor.
Is photographic memory real?
What the research says about photographic memory, eidetic imagery and HSAM, and how to test your visual recall.
Put it to the test
The tests and benchmarks the guides refer to, plus where to go next.
Working memory test
Hold numbers in mind and repeat them backwards. The test that matches the working memory section in both guides.
Short-term memory test
See how many items you can hold for a few seconds, the limit the types-of-memory guide describes.
Visual memory test
Remember which tiles lit up on a growing grid. A direct measure of the visual memory covered in the guides.
Memory score by age
How recall shifts from the teens through the 70s, so you can read your own result in context.
Improve your memory
Once you know how encoding works, these guides show the techniques that make it stick.
