Imagine dialing a phone number by having to look up each digit one at a time in the phone book. Normally, you look up the number and remember all seven digits long enough to get it dialed. Even with one digit at a time, you would have to remember each digit long enough to get it dialed. What if your brain could not even do that! We call this kind of remembering, “working memory,” because that is what the brain works with. Working memory is critical to everyday living.
