I have a clipping from the Richmond Times-Dispatch, July 28, 1997. It talks about an experiment conducted by David Merrell. His experiment was to observe the effects of music on mice. There were three groups: the Mozart mice, the hard rock mice, and a control group that listened to no music at all. His tests ran for three weeks.
At the end of the experiment, the control group had cut its navigation time in half. The Mozart mice did even better, cutting their time by 8½ minutes. But the hard rock group did much worse — taking 30 minutes to complete the maze, bumping into walls, staggering aimlessly about.
