Scientists in Scotland report that rock and roll may improve the brain. Specifically, "the sound of guitar-based rock such as Jimi Hendrix, AC/DC and the Red Hot Chili Peppers improves concentration and boosts memory."
This news report from the Times Online quotes Drs. Leigh Riby and George Caldwell, cognitive psychologists at Glasgow Caledonian University, who "monitored the brain activity of a group of 16 volunteers who were asked to perform a simple memory test while listening to rock and classical music. They were asked to do the same while listening to the sound of static and again in silence."
The classical stuff (Beethoven) "improved the concentration and memory of both groups," the researchers found. No surprise there. The so-called Mozart effect, which claims that certain kinds of classical music can yield short-term improvements in memory and other mental functions, has been talked about for several years now. But the surprise came when the scientists played rock and roll for the subjects.
"[R]ock music also had a significant effect on the cognitive performance of the rock fans," the Times reports. "Brain scans revealed that they required far less brainpower to complete the test successfully."
