Recent research suggests that creating "mind-body dissonance" -- when people think about something different from what they are doing — boosts creativity. To create this dissonance (and a good deal of laughter), arrange a group in a circle and have one person mime an action, such as vacuuming. A second person asks, "What are you doing?" The person miming needs to respond with an answer that is very different from vacuuming, such as "Dyeing my hair." Click here for further explanation. The idea comes courtesy of Jenise Fryatt, founder and chief trainer of Eventprov, which produces interactive experiences for team building, leadership training and self improvement.
