What struck me about this Scientific American article on creativity is what an impoverished notion of creativity the scientists have. Solving that little problem about how to get out of a tower with a rope is "creative"? If you're a ten-year-old, maybe. Or a psychologist. Creativity as problem solving. Is that what scientists really think? Maybe the imagination does interest itself in problems, or is engaged by problematic situations (to grab a term from John Dewey), but the process is more open-ended than the scientists appear to think it is.
