Automaticity refers to the ability to do something without thinking about it. It's like when you learn how to ride a bike or tie your shoes, and eventually you can do it without even having to think about the steps. That's automaticity! Your brain has learned the task so well that you don't need to put much effort into it anymore. Just like when you first learn to read, it takes a lot of work to sound out each word, but eventually, you get so good at it that you don't have to stop and think about each word anymore. That's automaticity! It's like your brain has made a shortcut so that you can do things really quickly and easily.
