University of Toronto psychologists induced a happy, sad or neutral state in each of 24 participants by playing them specially chosen musical selections. To instill happiness, for example, they played a jazzy version of Bach's Brandenburg Concerto No. 3. After each musical interlude, the researchers gave subjects two tests to assess their creativity and concentration.




Researchers have long proposed that negative emotions give people a kind of tunnel vision or filter on their attention, Anderson says. Positive moods break down that filter, which enhances creativity but prevents laserlike focus, such as that needed to recognize target letters in the second task, he says.

As for the myth of the depressed but brilliant artist, Anderson speculates that creativity may be a form of self-medication, giving a gloomy artist the chance to adopt a cheerful disposition.
