This study investigated the effect of listening to self-music therapy training (SMT) music, which was specially developed using musical expectancy violations, on improving brain concentration and activation. It was performed with a sample of 12 adults. Electroencephalograms (EEG) were obtained and analyzed after allowing the participants to listen to SMT music. An EEG device with eight channels was used to measure the brain waves. The changes in the EEGs were recorded when listening to SMT music in three states (stable, basic, and stimulated) after attaching the electrodes to the prefrontal cortex (Fp1 and Fp2), and the frontal (F3 and F4), temporal (T3 and T4), and parietal lobes (P3 and P4) according to the International 10/20 system. The EEG data were analyzed to determine the m-β wave appearance rate and absolute total power (ATP) for the three conditions, and a t-test was performed. The results showed that the rate of m-β wave appearance was higher in the stimulated and basic states than in the stable state (Fp1, Fp2, F4, T3, T4, P3, and P4) and higher in the stimulated state than in the basic state (Fp1, Fp2, T3, T4, and P4). The ATP was lower in the basic state than in the stable state (Fp2, F3, F4, and T3), but the ATP in the stimulated state was higher than in the basic or stable state in all areas excluding the left and right parietal lobes (Fp1, Fp2, F3, F4, T3, and T4). These results demonstrated that listening to SMT music by normal adults could increase brain concentration and activation.
本研究旨在探讨专门使用音乐期待违背现象开发的自音乐疗法训练（SMT）音乐对改善大脑注意力和激活能力的影响。该研究采用 12 名成年人作为样本进行。在允许参与者聆听 SMT 音乐后，获取并分析脑电图（EEG）。使用带有 8 个通道的 EEG 设备测量脑波。在将电极贴在前额皮层（Fp1 和 Fp2）、额部（F3 和 F4）、颞部（T3 和 T4）和顶叶（P3 和 P4）上之后，根据国际 10/20 系统，在三种状态（稳定、基础和刺激）下记录聆听 SMT 音乐时 EEG 的变化。分析 EEG 数据以确定三种状态下 m-β 波出现率和绝对总功率（ATP），并进行 t 检验。结果表明，与稳定状态相比，刺激和基础状态的 m-β 波出现率更高（Fp1、Fp2、F4、T3、T4、P3 和 P4），且刺激状态的 m-β 波出现率高于基础状态（Fp1、Fp2、T3、T4 和 P4）。与稳定状态相比，基础状态的 ATP 更低（Fp2、F3、F4 和 T3），但除左右顶叶外，刺激状态的 ATP 均高于基础或稳定状态（Fp1、Fp2、F3、F4、T3 和 T4）。这些结果表明，正常成年人聆听 SMT 音乐可以提高大脑注意力和激活能力。
