"The idea for the Mozart effect originated in 1993 at the University of California, Irvine, with physicist Gordon Shaw and Frances Rauscher, a former concert cellist and an expert on cognitive development. They studied the effects on a few dozen college students of listening to the first 10 minutes of the Mozart Sonata for Two Pianos in D Major (K.448). They found a temporary enhancement of spatial-temporal reasoning, as measured by the Stanford-Binet IQ test. No one else has been able to duplicate their results."
