A substantial body of research suggests that physically enacting difficult ideas can be a more effective way to bring them to life and encourage discussion than following conventional meeting etiquette of sitting, talking, and listening. SMU Associate Professor of Psychology Angela Leung and her colleagues at SMU have built on this theory, conducting experiments examining the effects of physical actions on cognition. They found, for example, that talking with one or both hands or working on puzzles while standing within or outside a large box had distinct effects on creativity and the application of knowledge.
