Copernican Revolution Activities

How powerful is human memory?  What are its limitations?  How much attention do we have to be paying to remember something?  In this activity you'll watch digits go by and try to remember them as best you can.  Try your best but don't worry if your memory isn't perfect.  Actually, nobody's is!

Note: Unlike most Copernican Revolution Activities, this one will work best if you can be completely focused while doing it (i.e., no distractions), if you use a larger screen (i.e., not a cell phone), and you make your screen its brightest

Estimated Time for Completion: 15 to 30 minutes

This activity is part of the Copernican Revolution Project, created by Dr. Kevin Grobman of California State University - Monterey Bay, to help everyone learn about psychological concepts through self-exploration. At the end you'll receive your personalized results, a guide for interpreting them, and a certificate of completion (e.g., for a teacher offering class credit).
 
Occasionally I combine your results with many other people to improve feedback.  Sometimes I combine different activities to discover new psychology findings and to share with others (e.g., conference presentations with other Psychology professors).  I also sometimes make anonymized datasets for students to practice statistical analyses and for researchers to test hypotheses.  Regardless, I never single particular people out and all responses are confidential.  Of course, you can share your results with anyone you choose!
 
Please feel free to skip any items you prefer not to answer.  Though your results may become less precise and less accurate the more items you skip, you'll still get your results.
(This question is mandatory)
Is it okay for your responses to part of the Copernican Revolution Project?  If you're not comfortable participating, that's completely okay!  You can still get your results, read the guides, and you'll still get a certificate for class credit (if applicable).
