内感受是感知从身体内产生的传入信号的过程，包括心率（HR）、胃信号等，并且被描述为一种在自我意识和自我的创造中至关重要的机制。心跳知觉任务是测量个体内感受准确性的工具。IAcc与自我意识的测量以及包括情绪敏感性、同理心、亲社会行为和有效决策在内的属性呈正相关。IAcc在一般人群中仅为中等，并试图确定由于其特定训练而可能具有较高IAcc的人群（例如，瑜伽，冥想）都没有成功。然而，最近对音乐家的一项研究表明，那些受过艺术训练的人可能表现出较高的IAcc。在这里，我们测试了20名专业舞者和20名女性控制参与者的心跳感知任务。舞蹈演员有较高的IAcc，这种效果是独立的较低的心率（身体健康的代理措施），计数能力，和知识的HR.An额外的组间分析后，中位数分裂的舞蹈演员组（基于多年的舞蹈经验）显示，初级舞蹈演员的IAcc不同于控制，和高级舞蹈演员的IAcc高于初级舞蹈演员和控制。一般艺术经验与IAcc呈正相关。IAcc与共情、情感体验和述情障碍的问卷测量之间没有相关性。这些研究结果进行了讨论的背景下，目前的理论interoception和情绪突出的特点，艺术培训可能与IAcc。
Interoception is the process of perceiving afferent signals arising from within the body including heart rate (HR), gastric signals, etc., and has been described as a mechanism crucially involved in the creation of self-awareness and selfhood. The heartbeat perception task is a tool to measure individuals' interoceptive accuracy (IAcc). IAcc correlates positively with measures of self-awareness and with attributes including emotional sensitivity, empathy, prosocial behavior, and efficient decision making. IAcc is only moderate in the general population, and attempts to identify groups of people who might have higher IAcc due to their specific training (e.g., yoga, meditation) have not been successful. However, a recent study with musicians suggests that those trained in the arts might exhibit high IAcc. Here, we tested IAcc in 20 professional dancers and 20 female control participants on a heartbeat perception task. Dancers had a higher IAcc, and this effect was independent of their lower heart rates (a proxy measure of physical fitness), counting ability, and knowledge about HR. An additional between-groups analysis after a median split in the dancer group (based on years of dance experience) showed that junior dancers' IAcc differed from controls, and senior dancers' IAcc was higher than both junior dancers and controls. General art experience correlated positively with IAcc. No correlations were found between IAcc and questionnaire measures of empathy, emotional experience, and alexithymia. These findings are discussed in the context of current theories of interoception and emotion-highlighting the features of arts training that might be related to IAcc.
