Why is focus so difficult for so many people?
With all of the amazing things our brains are capable of, it seems strange that simply paying attention to one thing for an extended period of time is such a challenge.
A big part of the answer is that our brains always have access to more information than they can fully process.
At any moment, your brain is getting input from what you see, hear, touch, smell, and taste, signals from inside your body, and a constant stream of thoughts, memories, and emotions.
There is too much to process all at once.
This is why the ability to focus exists in the first place.
We only have so much cognitive capacity at any one time, so your brain has to choose where to allocate that limited bandwidth.
The actual process of focusing involves several components working together:
* Setting the goal (what am I trying to do right now?)
* Picking out the important information
* Holding that goal in mind (working memory)
* Blocking distractions and impulses
* Noticing when your mind wandered and bringing it back
All of this depends on different brain regions working together in networks.
You can think of these networks like teams inside a company that need to coordinate to get one job done.
When your higher order brain systems, like the prefrontal cortex, help coordinate these āteams,ā it is called top-down processing.
This is the goal driven control that keeps you on task.
On the other side is bottom-up processing.
This is the reactive system that pulls your attention toward anything involuntarily.
With bottom-up signals, you do not really get to choose whether you respond.
For example you canāt choose whether or not you hear something. If your auditory cortex can detect the sound your brain will process it.
This is why some environments make focus feel so much harder.
It is not just about willpower. It is about how many bottom-up signals are pulling on your limited bandwidth.
The more of these bottom-up signals you can eliminate (noise canceling headphones, phone in another room, etc) the more cognitive power you free up to be able to focus better.
