The Mozart Effect was founded by Gordon Shaw and some of his fellow colleagues. This experiment showed how music affects the brain to increase intelligence and spatial-temporal memory.
In the first experiment, college students took an intelligence test before listening to the first 10 minutes of Mozart’s Sonata for Two Pianos in D Major.
After listening to the song, the students were given another intelligence test. The scores increased by eight to nine points. This showed that the spatial-temporal reasoning and memory were enhanced by listening to the music.
The experiment was repeated many times. The scores were never as drastic as the first, but they always increased
Also, EEG coherence studies were done along with fMRI studies that showed cortical blood oxygenation activation by the Mozart sonata. These studies, also, showed that the Mozart Effect is important for spatial-temporal reasoning and memory.
All of this information can be found in Gordon Shaw’s notes and article called The Mozart Effect.
