Abstract：
Interoception is the perception of the body\'s internal signals in response to various external and internal stimuli. The present study uses a novel method adapted from the CARdiac Elevation Detection Task to examine cardiac interoception objectively and subjectively in a unique context-in the presence of art. Self-report questionnaires were used to measure subjective interoceptive awareness, subjective interoceptive accuracy, and aesthetic appreciation. For objective interoceptive accuracy and sensibility, a wearable device (Shimmer) measured heart rate (HR) and connected to a mobile application to prompt two questions: \"Is your heart beating faster than usual?\" and \"How confident are you in your previous response?\" Participants explored an art gallery for 40 minutes while the Shimmer measured their HR and randomly prompted them to answer the questions. Using a Generalized Estimating Equation model, interoceptive sensibility was not found to predict the odds of submitting a correct response. It was also found that art does not improve participants\' perceptions of their HR. Finally, there was no relation between aesthetic appreciation and subjective or objective cardiac interoception. Despite lack of statistical significance, the current study\'s method presents an improved method by examining interoceptive accuracy in the moment under ecological conditions. To date, findings and methods used in interoception are inconsistent or flawed; the value in the current study lies in the development and demonstration of a method to examine how the environment influences the body and self-awareness across a wide variety of contexts, thereby offering a possible standardized measure of interoception for investigators to adopt.
摘要：
交互感觉是身体内部信号响应各种外部和内部刺激的感知。本研究使用一种改编自心脏抬高检测任务的新方法，在艺术存在的情况下，在独特的背景下客观和主观地检查心脏间感觉。使用自我报告问卷来测量主观交互感受意识，主观感知准确性，和审美欣赏。为了客观感知的准确性和敏感性，可穿戴设备（Shimmer）测量心率（HR）并连接到移动应用程序以提示两个问题：\“您的心跳速度比平时快吗？”和\“您对以前的反应有多自信？”参与者探索了一个美术馆40分钟，而Shimmer测量了他们的HR并随机提示他们回答问题。使用广义估计方程模型，没有发现交互感受能够预测提交正确应答的几率.还发现，艺术并不能改善参与者对他们HR的看法。最后,审美欣赏与主观或客观的心脏感觉之间没有关系。尽管缺乏统计学意义，当前研究的方法提出了一种改进的方法，通过在生态条件下检查瞬间感受的准确性。迄今为止,在相互感受中使用的发现和方法是不一致或有缺陷的;当前研究的价值在于开发和演示一种方法，以检查环境如何影响身体和自我意识在各种情况下，从而提供了一种可能的标准化的相互感觉测量，供研究者采用。
