When people want to be open or honest, they will often hold one or both palms out. When someone is concealing something, they often hide their palms behind their back, shove hands in pockets or arms-crossed.
There are 3 main palm command gestures:
Submissive, nonthreatening, or pleading.
2. Palm Down
Authority. Think of the Nazi salute.
3. Palm Closed
Also, palm closed with pointed finger. Wants listeners to submit.
Rubbing palms together shows positive expectancy.
Hands clenched together might seem a sign of confidence. It actually shows restrained, anxious, frustrated or negative attitude. The higher the position of the clenched hands the higher the person's frustration.
The Steeple is used when superiors give instruction or advice to subordinates. The steeple should be avoided when you want yo be persuasive.
The Face Platter is a positive form of flirting. A woman will place one hand on top of the other and lay her chin on top.
Hands Behind Back is a gesture of superiority, confidence and power.
Hand Gripping Wrist communicates frustration and attempt at self-control.
