In this scenario, and there were studies that look at these different functions over time.

The biggest one looked at data that came from the implicit association test people might have heard of, where you show these pictures of different things, and depending on how quickly you respond, it tells you something about your implicit thought processes.

They took some of the data from that.

This was published in one of the Nature journals a few years ago.

And what they showed was that

you can separate out reaction time versus processing speed because reaction time is a very, just the basic of response to a visual stimulus, whereas processing requires you, is based on how quickly you can process and remember the information that you're seeing.

You actually think, yeah.

So what they showed in this study was that reaction time kind of slowly decreases on average in a population of, it was about 1.2 million people, slowly decreases in sort of like from about our 30s and then maybe decreases even more once we get past about 60.

Processing speed on average tended to be more stable until about 60 years old and then tends to drop off.

So in what you're doing in these training modalities is you're being shown information

for a very short period of time, and then having to remember what it was you saw and where you saw it.

So it requires you to actually think and remember, process the information rather than just like responding to a stimulus.

I think it's going to depend a little bit on...

what is the things that you currently do, right?

So like crosswords are a good example.

Even if you're doing hard ones, if you look at the work of people like Gloria Mark, the things like crossword and Sudoku, they're less of like a true cognitive challenge, right?

It's almost has more of like a meditation, meditative like effect, right?

Which can be a good thing, right?

So you're focused, but not challenged really.

Whereas if we're trying to,
