Rauscher Et. Al. 1993 Study
Rauscher, Shaw, and Ky (1993) investigated the effect of listening to music by Mozart on spatial reasoning, and the results were published in Nature. They gave research participants one of three standard tests of abstract spatial reasoning after they had experienced each of three listening conditions: a sonata by Mozart, repetitive relaxation music, and silence. They found a temporary enhancement of spatial-temporal reasoning, as measured by the Stanford-Binet IQ test. Shaw and Rauscher claim that their work has been misrepresented. What they have shown is "that there are patterns of neurons that fire in sequences, and that there appear to be pre-existing sites in the brain that respond to specific frequencies."* This is not quite the same as showing that listening to Mozart increases intelligence in children.
Rauscher et. al. show that the enhancing effect of the music condition is only temporary: no student had effects extending beyond the 15-minute period in which they were tested. The study makes no statement of an increase in IQ in general, but in participants' spatial intelligence scores.

Famous quotes containing the word study:
“If I were in the unenviable position of having to study my work my points of departure would be the “Naught is more real ...” and the “Ubi nihil vales ...” both already in Murphy and neither very rational.”
—Samuel Beckett (1906–1989)
