本研究探讨了评委会对大提琴手演奏时动作和姿势的影响。24位大提琴专家在小组成员在场或不在场的情况下，随着节拍器的节拍演奏了一小段音乐。运动学分析表明，在面板的存在下，左臂移动运动的时间执行变得更少变化，更接近节拍器的节拍。相比之下，面板的存在对他们的空间精度没有可靠的影响。一项详细的体位分析表明，在演奏一个给定的高音时，左肘的角度与心率水平相关，尽管这种相关性的性质受到相关参与者主观状态的系统影响：如果焦虑，较高的心率与肘部更弯曲相关，如果不焦虑，则与肘部更伸展相关。我们的研究结果表明，生理状态的变化本身并不能可靠地预测大提琴演奏行为的变化，而是取决于生理状态和主观焦虑体验之间的相互作用。这突出了将表演焦虑与生理唤醒区分开来的必要性，为此，我们提倡使用特定的术语“表演唤醒”来描述表演者生理活动的增强。
This study investigated the effect of a panel of judges on the movements and postures of cellists in performance. Twenty four expert cellists played a short piece of music, to a metronome beat, in the presence and absence of the panel. Kinematic analyses showed that in the presence of the panel the temporal execution of left arm shifting movements became less variable and closer to the metronome beat. In contrast, the panel's presence had no reliable effect on their spatial accuracy. A detailed postural analysis indicated that left elbow angle during execution of a given high note was correlated with level of heart rate, though the nature of this correlation was systematically affected by the relevant participant's subjective state: if anxious, a higher heart rate correlated with a more flexed elbow, if not anxious then with a more extended elbow. Our results suggest a change in physiological state alone does not reliably predict a change in behavior in performing cellists, which instead depends on the interaction between physiological state and subjective experience of anxiety. This highlights a need to distinguish performance anxiety from physiological arousal, to which end we advocate currency for the specific term performance arousal to describe heightened physiological activity in a performer.
