Short-term memory is a requirement for Sustained Focus.
Short-term memory is the ability to hold on to information for short periods of time. As we shall see later, this is also a composite of at least three different processes, which we will describe in the topic on Memory.
One of the benefits of short-term memory is that we can remember what it is we are doing. This is certainly a factor in what we will discuss below as sustained focus.
There are times when I have gone to a room at the other end of the house to get something, and all of a sudden realized that I had forgotten why I was going there.
This is a good example of a lack of sustained focus. I was focused when I started out, but lost it somewhere in transit.
This is a natural occurrence when it happens once and a while, but when it becomes the rule and not the exception we have a problem.
