As you already know, body language accounts for 55% of our communication. It is the most obvious, easiest and most rewarding feature to synchronize on your way to rapport.

Synchronizing body language falls into two loose groupings: matching, which means doing the same thing as the other person (she moves her left hand, you move your left hand), and mirroring, which means, as it implies, moving as if you were watching the other person in a mirror (he moves his left hand, you move your right).

Particular gestures. Hand and arm movements are especially easy and natural to synchronize by matching and mirroring. Some folks raise their shoulders when they talk; others wave their hands around as they express themselves. Do whatever they do. If you find it uncomfortable at first, then go at it a little at a time until with practice you become an expert synchronizer. Just the fact that you’re noticing these different types of ges­tures is a big step in the direction of making people like you in 90 seconds or less.

Body posture. Overall posture is known as the atti­tude of the body. It shows how people present them­selves and is a good indicator of emotional state. That is why we sometimes refer to it as “adopting a posture.” When you can accurately adopt a person’s posture, you can get a fair idea of how he or she feels.

Overall body movements. Whether it’s a job interview or striking up a conversation at the museum fund-raiser, observe the person’s overall body movements, then gently mirror or match them. If he has a leg crossed, then cross a leg; if he’s leaning against the grand piano, do it, too. If she’s sitting sideways on the banquette, sit side­ways; if she’s standing with her hands on her hips, do the same. Body movements like leaning, walking and turning are easily synchronized.

Head tilts and nods. These are the simplest move­ments to synchronize. Fashion photographers know that most of the “feel” of a terrific cover shot comes from the “innuendo” created by subtle tilts and nods of the head. Sure, the face is important, but it’s the angles that carry the message. Pay close attention to them. Most good physicians and therapists find that they synchronize tilts and nods without giving it a second thought. It says “I hear you, I see what you’re saying and I feel for you.”

Facial expressions. Along with tilts and nods, syn­chronized facial expressions show agreement and understanding. They come naturally. When he smiles at you, your natural inclination is to smile back. When she shows wide-eyed surprise, give it back to her. Look around at the next luncheon or dinner you attend, and notice how those with the deepest rapport are doing it all the time. It’s an easy and natural, surefire way to make someone like you in 90 seconds or less. You can match the same amount and same style of eye contact. It may be fleeting, or direct or coy; whatever it is, pick up on it and return it in the same way.

Breathing. Pay attention to breathing. Is it fast or slow? Is it high in the chest, low in the chest or from the abdomen? You can usually tell how people are breathing by watching their shoulders or the folds in their cloth­ing. Synchronizing their breathing can be soothing and comforting to them.

Rhythms. The same rule applies for anything rhyth­mic. If she taps her foot, tap your pencil; if he nods his head, pat your thigh. In the right circumstances and with judicious application, this works well as long as it is beyond conscious awareness. If not, the next sound you hear may be the door slamming shut-or worse. Just use common sense and discretion.
