概念表征是以知觉为基础的，但当研究哪些知觉通道涉及时，研究人员通常会将他们的考虑限制在视觉、触觉、听觉、味觉和嗅觉上。然而，还有另一种主要的知觉信息形式，它与传统的五种感官不同；那就是内部知觉，或身体内的感觉。在这篇文章中，我们使用大量的研究数据(超过32,000个词的感知强度的通道特定评级)来探索互感信息如何有助于抽象和具体概念的知觉基础。我们报告了内感强度如何在抽象-具体光谱中捕捉到一种不同形式的知觉经验，但对抽象概念(如饥饿、宁静)明显比对具体概念(如容量、下雨)更重要。特别是，内感支配着情绪概念，特别是与恐惧和悲伤相关的负面情绪，比起其他抽象和等价性的概念更具主导性。最后，我们通过考察联觉强度在词汇识别的具体性效应中的作用来检验联觉强度是否代表了概念内容中的有价值的信息，并发现它比传统的五种感觉通道更能增强语义便利化。总体而言，这些发现表明，在促进抽象和具体概念的知觉基础方面，内部知觉具有与其他方式类似的地位。本文是主题主题：抽象概念的种类：大脑中的发展、使用和表征的一部分。
Conceptual representations are perceptually grounded, but when investigating which perceptual modalities are involved, researchers have typically restricted their consideration to vision, touch, hearing, taste and smell. However, there is another major modality of perceptual information that is distinct from these traditional five senses; that is, interoception, or sensations inside the body. In this paper, we use mega study data (modality-specific ratings of perceptual strength for over 32 000 words) to explore how interoceptive information contributes to the perceptual grounding of abstract and concrete concepts. We report how interoceptive strength captures a distinct form of perceptual experience across the abstract-concrete spectrum, but is markedly more important to abstract concepts (e.g. hungry, serenity) than to concrete concepts (e.g. capacity, rainy). In particular, interoception dominates emotion concepts, especially negative emotions relating to fear and sadness, moreso than other concepts of equivalent abstractness and valence. Finally, we examine whether interoceptive strength represents valuable information in conceptual content by investigating its role in concreteness effects in word recognition, and find that it enhances semantic facilitation over and above the traditional five sensory modalities. Overall, these findings suggest that interoception has comparable status to other modalities in contributing to the perceptual grounding of abstract and concrete concepts.This article is part of the theme issue 'Varieties of abstract concepts: development, use and representation in the brain'.
