I think that this one, this monitor that they would wear, would get all of that so we get their heart rate, their blood oxygen content, and there's like, something else that it measures as well, like their their blood pressure as well. So if their blood pressure is going up, that would be indicative of stress. And so if their self report and their physiological signs align, then we know, okay, here's a pretty strong we have, we have a strong correlation. Yeah, correlation, thank you, between these two, and it looks like their stress really did go up when they were talking about this specific topic. So there's just a lot of data points to keep in line. And that's just, it's just every, every new thing that we added just makes it more complicated. So the HRV monitor, I think, would get all of that content, but I would have to look into that. So we would have to look at, oh, two. BP and heart rate, yeah, so we have a heart rate here, so that'd be interesting. Okay, so self report, but then also the physiological I think I might need to take a health psychology class before I would feel comfortable doing all of this, because they do this all the time, but I haven't taken those classes yet, all right, so same thing would be happening here, right? So they're rating themselves, or, sorry, rating others also rating self, self after each round. So if they were the speaker, how well did they communicate what they were trying to say, maybe how how they felt connected with themselves, and then how well they felt heard, right? So they're rating the other person, then the silent listeners are also rating the others, right? So how well did that interaction go between the speaker and the listener.
