About the size of a fingernail, the rat’s brain hardly corresponds to the human’s in size, complexity or capability. So she’s reduced to examining rats’ brains. Starting with humans and proceeding to a simpler animal model is the reverse of the typical scientific approach, Rauscher acknowledges.īut medical ethics and the limits of technology prevent her from peering inside human heads to see if Mozart prompts neurons to make new, extensive connections that improve intelligence. The proof may rest inside the rats’ heads. Or, scientific rivals retort, it might mean they like music. It might mean, as they suggest, that music enhances a listener’s ability to solve problems in time, space and sequence-skills critical in math, science, engineering, architecture. And separate experiments showed that children who took piano lessons also scored higher on intelligence tests.
In previous experiments by Rauscher and others, college students who listened to the same sonata subsequently scored higher on intelligence tests.
