Hey kiddo, do you know how your brain works when you learn new things? One thing you might not have known is that your brain actually filters out certain information because it thinks it's not important to you. This is called latent inhibition.
Think of it like a filter in your brain that blocks some information from reaching your conscious thoughts. Your brain does this so it can focus on new, important things.
For example, let's say you see a new toy and you want to learn how it works. Your brain will focus on the parts that are new and interesting to you. But if you see the same toy over and over again, your brain starts to think it's not that important, and it will filter out some information.
That means that if you're trying to learn something that you've already seen many times before, it might take longer for you to learn it because your brain has already labeled it as unimportant.
It's like a supermarket shelf with lots of different cereals. Your brain only wants to focus on the new cereals that it's never seen before. It ignores the cereals that it has seen many times before because it thinks it already knows about them.
So, if you want to learn something that your brain has already labeled as unimportant, you might need to try harder and focus more on it to overcome the filter.
