Experience-based adaptation of emotional responses is an important faculty for cognitive and emotional functioning. Professional musicians represent an ideal model in which to elicit experience-driven changes in the emotional processing domain. The changes of the central representation of emotional arousal due to musical expertise are still largely unknown. The aim of the present study was to investigate the electroencephalogram (EEG) correlates of experience-driven changes in the domain of emotional arousal. Therefore, the differences in perceived (subjective arousal via ratings) and physiologically measured (EEG) arousal between amateur and professional musicians were examined.
A total of 15 professional and 19 amateur musicians listened to the first movement of Ludwig van Beethoven's 5th symphony (duration=∼7.4min), during which a continuous 76-channel EEG was recorded. In a second session, the participants evaluated their emotional arousal during listening. In a tonic analysis, we examined the average EEG data over the time course of the music piece. For a phasic analysis, a fast Fourier transform was performed and covariance maps of spectral power were computed in association with the subjective arousal ratings.
The subjective arousal ratings of the professional musicians were more consistent than those of the amateur musicians. In the tonic EEG analysis, a mid-frontal theta activity was observed in the professionals. In the phasic EEG, the professionals exhibited an increase of posterior alpha, central delta, and beta rhythm during high arousal.
Professionals exhibited different and/or more intense patterns of emotional activation when they listened to the music. The results of the present study underscore the impact of music experience on emotional reactions.
基于经验的情绪反应适应性是认知和情绪功能的一项重要能力。职业音乐家是一个理想模型,可用于引发情绪加工领域中由经验驱动的变化。由于音乐专业技能导致的情绪唤醒的中枢表征变化在很大程度上仍不为人知。本研究的目的是调查情绪唤醒领域中由经验驱动的变化与脑电图(EEG)的相关性。因此,研究了业余和职业音乐家在感知到的(通过评分得出的主观唤醒)和生理测量的(EEG)唤醒方面的差异。
共有15名职业音乐家和19名业余音乐家聆听了路德维希·凡·贝多芬第五交响曲的第一乐章(时长约7.4分钟),在此期间记录了连续的76通道脑电图。在第二个环节中,参与者评估了他们聆听时的情绪唤醒程度。在静态分析中,我们检查了整首乐曲时间过程中的平均脑电图数据。对于动态分析,进行了快速傅里叶变换,并结合主观唤醒评分计算了频谱功率的协方差图。
职业音乐家的主观唤醒评分比业余音乐家的更一致。在静态脑电图分析中,在职业音乐家中观察到额中θ活动。在动态脑电图中,职业音乐家在高唤醒期间后α、中央δ和β节律增加。
职业音乐家在听音乐时表现出不同和/或更强烈的情绪激活模式。本研究结果强调了音乐经验对情绪反应的影响。
