Lifehacker repeats some good tips from Ian's Messy Desk about ineffective body language in communication. These tips apply equally well for more formal presentations with the possible exception of crossing your legs since typically presenters are standing up. Among the body motions to avoid due to their potential negative perceptions by the audience include:
- Fiddling With a Watch Pen or Some Other Object
- Watching The Clock
- Crossing Your Arms
- Crossing Your Legs
- Hunching Your Body
- Touching Your Face
- Rubbing Your Nose
- Looking Away
Each of these convey a lack of confidence or discomfort with the topic, audience or your own professional self.
Can you think of any that should be added to his list?
