The research on neural correlates of intentional emotion communication by the music performer is still limited. In this study, we attempted to evaluate EEG patterns recorded from musicians who were instructed to perform a simple piano score while manipulating their manner of play to express specific contrasting emotions and self-rate the emotion they reflected on the scales of arousal and valence. In the emotional playing task, participants were instructed to improvise variations in a manner by which the targeted emotion is communicated. In contrast, in the neutral playing task, participants were asked to play the same piece precisely as written to obtain data for control over general patterns of motor and sensory activation during playing. The spectral analysis of the signal was applied as an initial step to be able to connect findings to the wider field of music-emotion research. The experimental contrast of emotional playing vs. neutral playing was employed to probe brain activity patterns differentially involved in distinct emotional states. The tasks of emotional and neutral playing differed considerably with respect to the state of intended-to-transfer emotion arousal and valence levels. The EEG activity differences were observed between distressed/excited and neutral/depressed/relaxed playing.
音乐表演者有意进行情绪交流的神经关联研究仍然有限。在本研究中，我们试图评估从音乐家身上记录到的脑电图模式，这些音乐家被指示演奏一段简单的钢琴曲谱，同时通过改变演奏方式来表达特定的对比情绪，并在唤醒和效价量表上对他们所表达的情绪进行自我评分。在情感演奏任务中，参与者被指示以传达目标情绪的方式进行即兴变奏。相比之下，在中性演奏任务中，参与者被要求严格按照乐谱演奏同一曲目，以获取演奏过程中运动和感觉激活的一般模式的对照数据。信号的频谱分析作为第一步应用，以便能够将研究结果与更广泛的音乐-情绪研究领域联系起来。采用情感演奏与中性演奏的实验对比，以探究不同情绪状态下差异涉及的大脑活动模式。情感演奏和中性演奏任务在意图传递的情绪唤醒状态和效价水平方面有很大差异。在痛苦/兴奋与中性/抑郁/放松演奏之间观察到脑电图活动差异。
