Want to ace an exam? Tell a friend what you learned (and memories are a LOT bigger than we think)"With a cue, suddenly, a lot of those details will come back," Sekeres said. "We don't permanently forget them, which would indicate lack of storage -- we just can't immediately access them. And that's good. That means our memories aren't as bad as we think." Much research on memory examines how brain damage or aging affects recall, but "we wanted to look at the normal course of forgetting in healthy brains -- and if anyone should have a good memory, it's healthy young adults," Sekeres said. "While the strategy of re-telling information -- known as 'the testing effect' -- has been shown to be a really effective study technique time and again, this study is novel in looking at how our memories change over time for a specialized group."
