Brain science makes better PowerPoint

Posted by:

A timely item in the week before TED2008: Stephen M. Kosslyn, professor and researcher in mental imagery at Harvard, is out to empower PowerPoint users with lessons from cognitive science.

Kosslyn spoke in Boston today at a meeting of the AAAS to share some quirkily titled guidelines (the Goldilocks Rule, the Rudolph Rule) that will help speakers play to the strengths — and sidestep the flaws — of the human brain. Good to know: The human brain likes to spot differences and oddities — and it doesn’t like to see more than four things at once. The rules might remind you of some of our more innovative TEDTalks presentations. (Via io9.) — Matthew Trost
