There's somebody around that we got to watch out for.

Maybe there's a leopard on the ground or something, right?

And then sometimes it's like, you're in my face.

Get out of here now, right?

And those are three different things.

And I can play that to you and I can tell you without hearing it.

And I know exactly what's being heard.

In the case of the antiphonal, hey, are you out there?

You see like the eye will just start scanning back and forth, right?

Because that's the right movement.

I'm looking for where's this coming from.

Exactly.

In the case of, you know, look, it's, you know, there's something to be scared, you know, threatened of, you're going to see dilation and you're also going to see some scanning, but it's not as slow.

It's a lot faster because there's a threat to me.

My autonomic system and my cognitive system are like reacting differently.

And in the case of you're in my face, it's going to be, you know, without even...

So without seeing you, if I hear another sort of aggressive sound, I'm going to react.

I'm going to be – I'm not scanning anywhere, but my dilation is going to be fast and I'm also going to be much more on top of things.

But we do this as humans too, right?

And it's like you can walk into a business meeting, you know, walk into a conference room and, you know, these subtle cues that are – we can't – don't always suppress them.
