When’s the last time you forgot your cell phone? What about your anniversary? We’ve all wished for a better memory at some point. And in those moments, what we’re generally referring to are our fact-based memory systems—the ones that store experiences and learned knowledge, the ones that can be strengthened by flash cards and mnemonic devices.
But there’s another type of memory that’s equally important, though less talked about: Working memory. Working memory holds items in the current moment, like digits in a phone number or lyrics to a song. It’s the mental capability that lets you keep multiple things in mind—say, competing goals for a project at work—and navigate a solution.
And it turns out working memory is fundamental to some of our most important cognitive abilities. People with a spacious working memory are, on average, better test-takers and better students, and they have more executive control and better problem-solving skills. A strong working memory is even correlated with greater lifetime earning potential.
