#430 โ€“ Charan Ranganath: Human Memory, Imagination, Deja Vu, and False Memories

I wouldn't necessarily describe it as a trauma. We can get into this whole stages of life thing, which I just love. Basically, those first few years, there are, I mean, think about it, a kid's internal model of their body is changing, right? It's like just learning to move. I mean, if you ever have a baby, you'll know that the first three months, they're discovering their toes, right?

And it's just nuts, right? So everything is changing. But what's really fascinating is, and I think this is one of those, this is not at all me being a scientist, but it's like one of those things that people talk about when they talk about the positive aspects of children is that they're exceptionally curious and they have this kind of openness towards the world.

#430 โ€“ Charan Ranganath: Human Memory, Imagination, Deja Vu, and False Memories

And so that prediction error is not a negative traumatic thing. I think it's like a very positive thing because it's what they use, they're seeking information. One of the areas that I'm very interested in is the prefrontal cortex. It's an area of the brain that, I mean, I could talk all day about it, but it helps us use our knowledge to say, hey, this is what I want to do now. This is my goal.

So this is how I'm going to achieve it and focus everything towards that goal, right? The prefrontal cortex takes forever to develop in humans. The connections are still being tweaked and reformed like into late adolescence, early adulthood, which is when you tend to see mental illness pop up, right? So it's being massively reformed.

Then you have about 10 years maybe of prime functioning of the prefrontal cortex. And then it starts going down again and you end up being older and you start losing all that frontal function. So I look at this and you'd say, okay, from you sit around episodic memory talks, we'll always say children are worse than adults at episodic memory.

#430 โ€“ Charan Ranganath: Human Memory, Imagination, Deja Vu, and False Memories

Older adults are worse than young adults at episodic memory. And I always say, God, this is so weird. Why would we have this period of time that's so short when we're perfect, right? Or optimal. And I like to use the word optimal now because there's such a culture of optimization right now.

And it's like, I realized I have to redefine what optimal is because for most of the human condition, I think we had a series of stages of life where you have basically adults saying, okay, young adults saying, I've got a child and, you know, I'm part of this village and I have to hunt and forage and get things done.
