对63名焦虑的音乐表演者进行了一项假设，即高心率和低感知技能比低心率和高感知技能与更大的恐惧回报相关。音乐家们在每周四次的课程中学习渐进式肌肉放松和注意力集中技能。在训练课程之间和三个月的随访评估中评估主观恐惧的恢复情况。表演质量评分作为行为测量，预期心率作为生理测量，苦恼量表主观单位作为主观测量。根据心率和感知技能预评估水平的中位数分裂，形成四个分类组(高心率，低感知技能；高心率，高感知技能；低心率，低感知技能；低心率，高感知技能)。每一组都表现出主观恐惧的减少，而心率较高的受试者心率降低，在评估后总体表现质量有所提高。在心率较高的受试者中，无论他们感觉到的技能状态如何，后续的恐惧回归都是明显的。心率高的受试者比现在的心率受试者报告了更多的焦虑想法。感知到的技能与恐惧的回归并没有明显的联系。事后比较表明，与没有表现出恐惧回归的受试者相比，表现出后续恐惧回归的受试者心率更高，感知技能更低，焦虑想法更多，表演技能更少，在后续时间段的表现也更少。然而，初始心率是预测后续恐惧程度的唯一重要指标。
The hypothesis that high heart rate and low perceived skill would be associated with greater return of fear than low heart rate and high perceived skill was investigated in a group of 63 anxious musical performers. Musicians were taught progressive muscle relaxation and attention-focusing skills over the course of four weekly sessions. Return of subjective fear was assessed between training programme sessions and at a three-month follow-up assessment. Performance quality ratings served as the behavioural measure, anticipatory heart rate as the physiological measure, and subjective units of distress scales as the subjective measure. Four classification groups (high heart rate, low perceived skill; high heart rate, high perceived skill; low heart rate, low perceived skill; and low heart rate, high perceived skill) were formed on the basis of median splits of heart rate and perceived skill pre-assessment levels. Each group demonstrated subjective fear reduction, while heart rate reduced in the high heart-rate subjects, and performance quality improved overall at post-assessment. Follow-up return of fear was apparent in high heart-rate subjects, regardless of their perceived skill status. High heart-rate subjects reported more anxious thoughts than did now heart-rate subjects. Perceived skill was not clearly associated with return of fear. Post-hoc comparisons indicated that subjects who demonstrated follow-up return of fear had higher heart rate, lower perceived skill, more anxious thoughts, less performance skill and fewer performances over the follow-up interval than subjects who did not demonstrate a return of fear. However, initial heart rate was the only significant predictor of follow-up fear levels.
