Crossed legs are usually a sign of resistance and low receptivity, and are a bad sign in a negotiation.
Out of 2,000 negotiations videotaped by Gerard I. Nierenberg and Henry H. Calero, the authors of "How to Read a Person Like a Book," there wasn't a single settlement when one of the negotiators had their legs crossed.
Psychologically, crossed legs signal that a person is mentally, emotionally, and physically closed off — which may mean they're less likely to budge in a negotiation.
Eye contact shows interest — both positive and negative.
Being stared at by a stranger who appears large or ominous can be seen as a threat and elicit a fear response ... However, the gaze of a potential s*xual partner causes arousal that can be interpreted positively — as a s*xual invitation.
In an attempt to avoid looking shifty-eyed, some liars will purposefully hold their gaze a touch too long, so that it's slightly uncomfortable.
They may also stand very still and not blink.
If someone is receptive to your humor, they're likely interested in you, humor plays a pivotal role in human development. It serves as a way of signaling a desire for a relationship.Look for a lack of crinkles around the eyes to detect a fake smile.
The smile, it turns out, is all about the crow's-feet around your eyes. When you're smiling joyfully, they crinkle. When you're faking it, they don't.
Raised eyebrows are often a sign of discomfort.
Remember worry, surprise, or fear can cause people to raise their eyebrows in discomfort. So if someone compliments your new hairstyle or suit with their eyebrows raised, it may not be sincere.
If their voice goes up or down, they're likely interested.
Whether you know it or not, your voice range shows your interest.
If they mirror your body language, the conversation is probably going well.
When two people are getting along, their postures and movements mirror each other's. When your best friend crosses her legs, you will, too.
A "cluster" of gestures shows a real feeling of connection.
Attraction isn't communicated through one signal but a sequence. After making eye contact, she looks down a bit, gathers or otherwise preens her hair, and then looks up at you while her chin is tipped.
A shaking leg signals a shaky inner state.
A shaky leg signals anxiety, irritation, or both.
A clenched jaw, tightened neck, or furrowed brow shows stress.
The bus leaves without us, and we are clenching our jaws, rubbing our necks. We are asked to work another weekend, and the orbits of our eyes narrow as our chin lowers.
Expansive, authoritative postures show leadership.
Whether they're innate or learned, there are a number of signals and behaviors people use when they feel that they're a leader, or at least are trying to convince you that they are - holding an erect posture, walking purposefully, steepling and palm-down hand gestures, and generally open and expansive body postures.
Crossed arms can signal defensiveness, depending on the context.
It's easy to seize on body-language cues, but it's important to be aware of the context. While crossed arms typically indicate that someone is closed off, people are also more likely to cross their arms when it's cold and when their chair doesn't have an armrest.
Caveat: Be aware of the environment before making a decision or changing strategy based on these types of behaviors.
