[PConline News] "Is Mozart's music smarter?" rumors have been circulating among expectant mothers since the 1990s. Mozart's music has become the best-selling prenatal music. However, the proposition that the academic community calls the "Mozart effect" has always been the focus of debate among scientists. Recently, Prof. Zhongde Dezhong and his research team at the University of Electronic Science and Technology of China discovered that the rhythm of music may be the key to the Mozart effect in rats. The research paper was published online on the 21st in the "Scientific Report" of the British Natural Publishing Group.
In 1993, Frances Rauscher of the University of California in the United States published a paper in the journal Nature to introduce his findings: Listening to Mozart's 448 music can improve human spatial reasoning and memory. Since then, the global spread from the scientific community to the business community has whipped up a "Mozart effect" whirlwind. However, the scientific community has questioned the existence and reliability of this effect.
Prof. Xia Yang of the University of Electronic Science and Technology told the reporter of the Science and Technology Daily: “The Mozart effect mainly refers to listening to Mozart music or similar music, which can improve the spatial memory ability of the subjects. However, after listening to Mozart music, all cognitive abilities can be improved. Xia Yang introduced that the focus of the Mozart effect debate is mainly on the mechanism of the Mozart effect. Some researchers believe that it is due to the preference of the subjects for music, which improves the spatial memory ability; also some researchers believe that this effect is due to music directly. Activation of neurons in the brain increases the spatial memory of the subjects. In some subsequent studies, the selection of musical works and measurement tools have an impact on the experimental results and cannot objectively prove the existence of the Mozart effect.
In the study of Ju Dezhong and Xia Yang, the researchers used reverse Mozart (by matching the notes of Mozart's 488 music in reverse order) to ensure that the physical elements of the music listened to by the participants were the same, with 60 bits. College students and 45 rats were tested separately. The researchers examined changes in the levels of neurological factors associated with learning and memory at different time points after the rats listened to music, and the effects of music on new neurons in the brain. These experimental results all support the existence of the Mozart effect.
In order to study which music elements contribute to the Mozart effect, the researchers found that keeping Mozart's rhythm composition can produce similar effects to Mozart's music by changing the rhythm or pitch components of Mozart's music, while retaining only the pitch component. There is no obvious effect on the music. Explain that the rhythm component may be a key factor in the Mozart effect. In both human and rat experiments, the researchers found that the rhythm of music played a key role in the musical effect. The researchers therefore believe that the practical application of further study of the rhythm of music may provide some new treatment strategies for the dysfunction of the nervous system. Xia Yang introduced that the rhythm of Mozart's music is similar to that of humans. The researchers then hope that they can find the principle of natural evolution of animals from animals to humans.
At the same time, Xia Yang also reminded everyone: "In the study we also found that reverse Mozart music has a significant negative effect on people and rats' cognition. At present, it is easy to achieve reverse music playback through computer software or other tools. Everyone needs to pay attention to the negative effects of reverse music."
