It's called selective attention. It consists of a very selective attention as the name sáis because we focuse on a single thing ignoring the rest, and that's why it is called that way. Most human beings have this type of attention because they focuse on a single thing, sometimes this attention is better for concentration but some others we also need to focuse in more than one thing to get a better result. You can work on your selective attention to improve it so you can focuse on the important things, there are various methods to do it and from my point of view are very useful. Hope this answered helped you and have a great day.
