What is it?
Working Memory refers to the ability to remember instructions or keep information in the mind long enough to perform tasks. We use simple working memory when we look at a phone number and keep it in mind while we dial it. Working memory is the sketch pad of the mind where we put things to think about and manipulate.
Children have to use their working memory throughout the school day, whether it is keeping in mind instructions, doing arithmetic, working in groups, or even crossing the room to sharpen a pencil. Simple working memory tests are highly correlated with IQ scores. There is evidence that working memory exercises can by themselves produce improvement in the symptoms of Attention Deficit Hyperactivity Disorder, probably because the same areas of the brain are associated with sustained attention, response inhibition and working memory.
