感知内感信号的能力在许多情绪理论中扮演着核心角色。本研究旨在探讨内感意识与情绪信息的有意识加工和记忆之间的关系。记录了两组参与者在基线和情感图片呈现期间的心率变化，这两组参与者的心脏意识不同。在60分钟的休息后，进行了一项识别任务。统计分析显示，在具有高度内在感觉意识的参与者中，对愉快和令人不快的刺激的心率减速显著增强。在随后的图片再认任务中，高内感意识的被试对愉快和不愉快图片的回忆表现出更好的回忆，而对于中性内容的图片，不同内感觉组的被试没有发现差异。我们的结果表明，心脏信号的感知与情绪刺激的处理和识别之间存在着很强的联系。高的相互感觉意识与对情绪刺激的生理反应增加有关，因此在研究健康受试者和临床人群的心血管反应性时，高互感意识是一个重要的中介变量。
The ability to perceive interoceptive signals plays a central role in many theories of emotions. The present study was designed to investigate the relationship between interoceptive awareness and the conscious processing and memory of emotional information. Heart-rate changes were recorded during baseline and affective picture presentation in two groups of participants, differing in cardiac awareness. After a 60-minute break, a recognition task was conducted. Statistical analyses revealed significantly stronger heart-rate deceleration to pleasant and unpleasant stimuli in participants with high interoceptive awareness. In the subsequent picture recognition task, participants with high interoceptive awareness demonstrated a superior recall of pleasant and unpleasant pictures, while no differences were found between interoceptive awareness groups for pictures of neutral content. Our results demonstrate a strong relationship between the perception of cardiac signals and both the processing as well as the recognition of emotional stimuli. High interoceptive awareness was related to increased physiological responses to emotional stimuli and is therefore an important mediating variable when investigating cardiovascular reactivity both in healthy subjects as well as in clinical populations.
