I thought this was interesting. and I love to share tidbits. Are Your Hands Mumbling? Arms and hands are part of effective communication. And just as with speaking, clarity makes a difference. * Hands are most effective when they reinforce what is being said. * Arms and hands mid-level, in conjunction with what is being said, help clarify. * When arms/hands are more enthusiastic than the voice, they can be distracting. * Unison arms/hands, pumping in rhythm, are like speaking in monotone. * Arms/hands above the head tend to read as shouting. * Arms/hands low with little movement tend to read as whispering. * Arms/hands locked at the waist, in a number of positions, are like mumbling. more on this in March.. written by Hilary Blair
