Hand And Arm Gestures
The two most common hand and arm gestures that are advised to be avoided are putting the hands in the pocket and arm crossing. The first gesture, hands in the pocket, may indicate four things: he may be hiding something, bored and uninterested, refusing to perform a task, or nervous and anxious.
The latter gesture, crossing the arms across the chest may mean three things. The person may be protecting from a verbal attack, simply feeling cold, or even probably lying. But it may also indicate that he is disagreeing with you if you are the one talking.
Another common hand gesture is the clenched fist. This indicates anger, frustration, defensiveness, resistance, or confidence.
When Sitting Down And Standing Up
Your emotions can also be reflected by the way you stand or sit. Proper posture is with the shoulders squared and pulled back, but without too much tightening of the back muscles. With the back muscle rigid and stiff, you will appear very tense and nervous. Do not slouch as well. Slouching signifies laziness or boredom.
It is indeed beneficial if you know how to decipher the meanings of another person's body language. However, the indications are not true at all times. Not all impressions from reading body language last. This will only be supportive if you already have an idea on the personality of the person.
