ABSTRACT

John Cacioppo and colleagues’ Somatovisceral Afference Model of Emotion (SAME) highlighted the importance of interoception in emotional experience. Here we compare how the SAME and the more recent theory of constructed emotion (TCE) view the role of interoceptive signals in creating emotional experiences. We describe the characteristics of touch sensations that are carried by thin, unmyelinated fibers called C-tactile afferents (CTs) to the posterior insula, and are thus deemed interoceptive despite their typically social (external) origin. We explore how this social interoceptive input might contribute to the emotion-related effects of social touch more generally, and speculate that all social touch, with or without CT afferent stimulation, can directly influence allostasis, or the predictive regulation of short- and long-term energy resources required by the body. Finally, we describe several features of CT-optimal touch that make it a potentially useful tool to help illuminate basic interoceptive mechanisms, emotion-related phenomena, and disorders involving atypical affect or somatosensation. These proposed ideas demonstrate the long intellectual reach of John Cacioppo and Gary Berntson’s highly productive scientific collaboration, which was formative for the fields of social neuroscience, social psychophysiology, and affective neuroscience.

 抽象的

John Cacioppo 及其同事的情绪躯体内脏传入模型 (SAME) 强调了内感受在情绪体验中的重要性。在这里，我们比较了 SAME 和最新的建构情感理论 (TCE) 如何看待内感受信号在创造情感体验中的作用。我们描述了触觉的特征，这些触觉是由称为 C 触觉传入 (CT) 的细无髓鞘纤维传递到后岛叶的，因此被认为是内感受的，尽管它们通常是社会（外部）起源的。我们探讨了这种社会内感受输入如何更广泛地影响社交接触的情绪相关效应，并推测所有社交接触，无论有或没有 CT 传入刺激，都可以直接影响动态平衡，或短、长接触的预测性调节。术语“身体所需的能量”。最后，我们描述了 CT 最佳触摸的几个特征，这些特征使其成为一个潜在有用的工具，可以帮助阐明基本的内感受机制、情绪相关现象以及涉及非典型情感或躯体感觉的疾病。这些提出的想法展示了约翰·卡西奥波和加里·伯恩特森高产的科学合作的长期知识影响力，这对社会神经科学、社会心理生理学和情感神经科学领域的形成具有重要意义。
