What is Working Memory?

Working memory is your brain's Post-it note, says Tracy Packiam Alloway, Ph.D., assistant professor of psychology at the University of North Florida in Jacksonville, Florida. "It makes all the difference to successful learning," she says.

You can think of working memory as the active part of your memory system. It's like mental juggling, says H. Lee Swanson, Ph.D., distinguished professor of education with the Graduate School of Education at the University of California, Riverside.

"As information comes in, you're processing it at the same time as you store it," he says. A child uses this skill when doing math calculations or listening to a story, for example.

She has to hold onto the numbers while working with them. Or, she needs to remember the sequence of events and also think of what the story is about, says Swanson.

Brief by design, working memory involves a short-term use of memory and attention, adds Matthew Cruger, Ph.D., neuropsychologist with the Learning and Diagnostics Center at the Child Mind Institute in New York City.

"It is a set of skills that helps us keep information in mind while using that information to complete a task or execute a challenge," he says.

Working memory is like a foundation of the brain's executive function. This is a broad and deep group of mental processes. They allow you to do things like plan ahead, problem solve, organize, and pay attention.

"Working memory helps us stay involved in something longer and keep more things in mind while approaching a task," says Cruger. "And, how can you plan ahead if you don't use working memory to keep your goal in mind, resist distractions, and inhibit impulsive choices?"

But if you struggle with working memory, pieces of information may often evade your grasp like a quickly evaporating dream. You find yourself stripped of the very thing you need most to take action.
