Everybody knows situations where activities requiring concentration and high level consciousness can over time become a "background" task.
- you read a text aloud but think about other things
- you drive a car but it just "happens" and you can listen to the news
Question: is it measurable to demonstrate how an activity "goes background" in the brain? What is the current state of research, or at least what are proper neuroscience terms to look for in this context?
