An experiment suggests doodling may be more than just a pleasant waste of time and paper.
All sorts of claims have been made for the power of doodling: from it being an entertaining or relaxing activity, right through to it aiding creativity, or even that you can read people's personalities in their doodles.
The idea that doodling provides a window to the soul is probably wrong. It can seem intuitively attractive but it falls into the same category as graphology: it's a pseudoscience (psychologists have found no connection between personality and handwriting).
Although it's probably a waste of time trying to interpret a doodle, could the act of doodling itself still be a beneficial habit for attention and memory in certain circumstances?
