Are you good at retrieving information from your short-term memory? Do this test (link to: labinthewild.org) to find out and then see how your performance compares to others. It only takes just under 10 minutes to do, and has been designed to help researchers understand how short-term memory works.
Since my school days, my short-term memory has always been better than my long-term memory, so I don’t find tests like this one SO difficult! 😉
