Objectives : This study aimed to evaluate the effects of background music (BGM) on work efficiency while listening to classical and popular music by means of neuroscientific methods. First, we measured the work efficiency with/without BGM using Uchida-Kraepelin test, and found that the efficiency rise "with" background music (BGM). Then we evaluated the effects of BGM on work efficiency by examining changes in brain activation. Subjects and Methods : Four female and four male undergraduate students participated in the study (mean age, 22±0.7 years). Uchida-Kraepelin test is used as the scale of simple work, and we compared the score of the test with and without music to find the difference. A classical and a popular music (Pachelbel Canon and Tohoshinki (TVXQ!), respectively) were used individually for BGM. During each trial, brain activation of the prefrontal cortex was measured using near-infrared spectroscopy (NIRS). Results : Work efficiency, as measured by the Uchida-Kraepelin test, was significantly increased (p<0.05) when listening to classical music. The functional localization of brain activity in the prefrontal cortex during simple work while listening to music was shown by NIRS measurements. Conclusions : The effects of BGM on simple work were observed in the left lateral prefrontal cortex. Brain activation was increased when listening to classical music than that of popular music. For both sentences, your alternative suggestion seems to be great!
