Attention is a cognitive process that lets you selectively focus and concentrate on one aspect of your surrounding and environment while disregarding others. Somehow, when you are paying attention to something, you are allocating resources and concentrating on that specific information.
The capacity to focus and selectively pay attention is an essential daily life skill. You use your attention for most of the activities you perform in your daily life. It is important to keep a healthy brain and train your cognitive abilities so you can maintain and improve your capacity to pay attention, concentrate and focus.
