Think about a time when you watched a TV show you love, with a person who had never seen it. Often, when a person is a novice, he or she can get really confused and overwhelmed by all the details!
- You don't know which characters are important
- You have a hard time keeping things straight when settings or perspectives jump around
- You don't know when new interactions between characters relate to things that have happened between them before (or in general, what their history is)
- The list goes on!
- Watching an old episode a second time shows you details that you didn't pick up on or recognize as important the first time.
- Watching a new episode is different because, as new information comes in, you are able to quickly sort details into categories. You know when things are surprising or expected, repetitive or new.
This is similar to reading a text!
When you are a novice about the topic, you can get bombarded by details. When you are an expert on the topic, you can sort new and old information into categories or big ideas.
This helps you make sense of the information, AND helps you remember it!
