Investigation of the effect of alpha wave-containing music on the cognitive performance and brain activity of university students
Keywords:alpha music, cognitive performance, electroencephalography, university students
Cognition is one of the most vital brain functions, which ranges from assisting students in recalling what they have been taught to assisting us in concentrating while accomplishing chores. Nowadays, many jobs require advanced cognitive abilities, particularly among high school and university students. As a result, preserving or improving our cognitive abilities has become necessary in modern society. Alpha-wave music, which targets the brain frequency range from 8 to 12 Hz, is a promising approach to boosting cognitive performance. The purpose of this study is to evaluate the immediate, short term, or long term effects of alpha wave music on the cognitive performance and brain activity of students. In an online experiment, two groups of students were recruited and randomized into control and experimental groups. The experimental group was required to listen to alpha music for two weeks (here called the intervention). Participants from both groups will have their cognitive performance assessed before, immediately after, and two weeks following the intervention. In the immediate effect experiment, another group of participants have their alpha relative power evaluated while performing different tasks. The results of the online experiment revealed that feedback from participants listening to alpha music are mostly positive, while the response time of cognitive tasks indicated an improvement trend (p<0.05). The positive potential of alpha music was also confirmed with the immediate effect study where the alpha power was higher during alpha music exposure than during the remaining sessions. In conclusion, this study provided preliminary evidence to support the implementation of alpha music intervention to improve the cognitive function of students.
