I do too.

I suspect they're a form of confirmation bias, however, because it's not easy to remember that you heard about an idea or term you're unfamiliar with. On the other hand, something you've just recently heard or learned stands out: it reinforces the lesson you've just learned.

Thanks!

This has me down a rabbit-hole because I'm now trying to find the name for a related concept: once you've learned a new idea/model, you start to notice how it applies to everything around you. I find this happening most often with algebraic ideas but the article you linked alludes to the fact that you're liable to notice this effect at play more in the days after reading about it. I want to call it overfitting but that's not quite right.

This is the Law of the Instrument: if all you have is a hammer, then everything looks like a nail.

I don't think that's really the same meaning. Here it's more like, if you're given a hammer, you'll notice a lot of nails you can use more easily now.

Once you've learned a thing, or "studied it" much more, you are more swift in perceiving it, processing, and storing that encounter. Be it an idea, name, combination of low frequency words... Otherwise, many things go in one ear and out the other.

What really gives me the goose bumps is if you're, say, listening to a recording of a lecture while looking out the window watching a leaf tumble through the wind - and then the professor uses a leaf blowing in the wind analogy. It's not something you do very frequently; watch and listen to two independent events.

>something you've just recently heard or learned stands out

Not only does it stand out, at times it seems to appear more frequent. I found out that was called the Baader-Meinhof Phenomenon.
