Interoception: The Forgotten Modality in Perceptual Grounding of Concepts


Concepts are the basis of the human cognitive system, and the question of what constitutes the content of these mental representations has long occupied the cognitive sciences. Work in psychology, linguistics and cognitive neuroscience has converged on the idea that we develop our conceptual representations through our perception of and interaction with our environment. To date, such research has typically restricted consideration to the perceptual modalities of vision, touch, sound, 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 within the body. In this paper, we explore the role of interoception in the perceptual grounding of concepts.
