个体对内部身体信号的敏感性（“内感受意识”）已被证明与广泛的认知和情感功能相关。内感受性意识主要通过测量心脏信号的灵敏度（“心脏意识”）来评估，心脏信号可以通过心跳感知任务非侵入性地测量。这是一个悬而未决的问题，心脏意识是否与其他身体，内脏功能的敏感性有关。本研究采用无创性方法，探讨健康女性心脏意识与胃功能敏感性的关系。通过心跳跟踪任务评估作为心脏意识测量的心跳感知，并通过水负荷试验评估胃敏感性。胃电图（EGG）测量胃肌电活动和主观感觉的饱胀，效价，觉醒和恶心进行了评估。结果表明，心脏意识与摄入的水量和水负荷后的正常胃活动呈负相关。然而，心脏意识好和差的人在饮酒后的饱腹感、恶心感和情感感受的主观评分方面没有差异。这表明，良好的心跳感知者摄入较少的水，因为他们主观上感觉到更强烈的饱腹感信号，在此较低的水摄入量相比，差的心跳感知者摄入更多的水，直到感觉到同样的饱腹感。这些研究结果表明，心脏意识与胃功能的更高敏感性相关，表明胃和心脏模态的内感受过程具有普遍敏感性。
The individual sensitivity for ones internal bodily signals (“interoceptive awareness”) has been shown to be of relevance for a broad range of cognitive and affective functions. Interoceptive awareness has been primarily assessed via measuring the sensitivity for ones cardiac signals (“cardiac awareness”) which can be non-invasively measured by heartbeat perception tasks. It is an open question whether cardiac awareness is related to the sensitivity for other bodily, visceral functions. This study investigated the relationship between cardiac awareness and the sensitivity for gastric functions in healthy female persons by using non-invasive methods. Heartbeat perception as a measure for cardiac awareness was assessed by a heartbeat tracking task and gastric sensitivity was assessed by a water load test. Gastric myoelectrical activity was measured by electrogastrography (EGG) and subjective feelings of fullness, valence, arousal and nausea were assessed. The results show that cardiac awareness was inversely correlated with ingested water volume and with normogastric activity after water load. However, persons with good and poor cardiac awareness did not differ in their subjective ratings of fullness, nausea and affective feelings after drinking. This suggests that good heartbeat perceivers ingested less water because they subjectively felt more intense signals of fullness during this lower amount of water intake compared to poor heartbeat perceivers who ingested more water until feeling the same signs of fullness. These findings demonstrate that cardiac awareness is related to greater sensitivity for gastric functions, suggesting that there is a general sensitivity for interoceptive processes across the gastric and cardiac modality.
