How to Improve Memory & Focus Using Science Protocols | Dr. Charan Ranganath

I think I had the iPhone 3, which was whenever that came out. Yeah. So until then, I would check email when I was at a computer. When I'm not, I don't think about it. Now it's always there and you get alerts on your phone, right? So let's play this out now. We're having this great conversation.

Let's say we leave, we talk about skateboarding and punk rock and like, yes, why didn't we talk about this on the podcast? We're having a great conversation, right? But now let's say I didn't put my phone on focus mode and I start getting all these little beeps on my phone. I know people. I know I played in a band with somebody who had ADHD.

And he would โ€“ anytime we were in a conversation, he would just check his text messages. Sometimes he would text in front of me, right? So what happens is every time you do that โ€“ you're essentially shifting your task, your mindset changes, your intention is somewhat changed by this new task, right? So now I've shifted and there's a cost associated with that.

In fact, actually people who study this, there's like four or five different costs that go on. It makes you slower to do the new thing, right? Now I go back to the conversation. Well, now I have another cost associated with that. And so I'm not there where you are in this moment. I'm several seconds behind you, and I'm still catching up while you're talking.

And that requires even more control to get caught up and get back up to speed. So I'm straining my natural resources. I'm straining my cognitive control by shifting back and forth. But here's an even worse part of it. So a memory, we haven't even talked about this, but it's like a lot of our forgetting happens because we have these blurry memories. They're not distinctive. They don't.

You don't get a population of neurons that shouts out loud, hey, that's this conversation I had with Andy, right? It's just kind of this blurry sense of I talked to someone on a podcast. I'm not saying that this will happen now because it won't. So I have this blurry memory. Well, why does that happen?
