Wish you could tell on a date or a job interview if the other person likes you? Wouldn't it be great to know when someone is lying to you? Watch these videos on how to read body language and you'll be able to decipher what people are thinking and feeling just by looking into their eyes and observing their facial expressions and body gestures.
So the eyes are a very useful ways to sometimes to determine truthfulness, and there’s a lot of things so the first thing, let’s talk about eye contact. There’s not one shred of academic research that shows breaking eye contact is an indication of lying. However, everybody believes that. Everybody believes that If you break eye contact you’re lying, there’s not one shred of research that shows that, okay. However, there is some research that shows that people tend to make an overbearing amount of contact when they lie, because they think that you, you think that if they break eye contact that you are going to perceive them as lying. So one of the things you’ll see people do is, I swear to God, I swear to God, I didn’t do that, and then they make an unusual amount of eye contact, which is a deviation from how they make could be an indication of lying. Also blink rates, it’s really a strong way of determining, it’s not a strong way, but it’s one of the ways you could maybe use to determine whether someone is lying. So there’s two responses with blink rate. Our blink rate tends to increase when we get really emotional about something, all right. So blink rate is coordinated with emotion all right, so you’ll see an increase in blink rate right there. But blink rate also decreases when we experience something called cognitive overload. And what cognitive overload is, it’s basically when our brain, lying requires more cognition then telling the truth. So lying requires more cognitive facilities than when you are telling something honest. So what tends to happen behaviors tend to stop when you are lying. So one of the cool things you’ll tend to see is, some research points to, when you see someone is telling a lie, you’ll see a decrease in cognitive overload, and when they get away with it, you’ll see an increase in blink rate, because they just got away with it. So it’s kind of cool, but it’s not highly accurate and it’s hard to look for, but it’s something you can be mindful of.
