Distinguishing volumetric content from perceptual presence within a predictive processing framework.

Summary

The article argues that perceptual presence—the sense that an object is really there—differs from volumetric content, which is the sense of an object's three-dimensional shape. Using predictive processing theory, it distinguishes between agent-active expectations (which generate presence) and object-active expectations (which generate volumetric content). Evidence from virtual reality technologies shows how presence is created. The argument clarifies the relationship between sensorimotor enactivism and predictive processing.

Abstract

I argue for an overlooked distinction between perceptual presence and volumetric content, and flesh it out in terms of predictive processing. Within the predictive processing framework we can distinguish between agent-active and object-active expectations. The former expectations account for perceptual presence, while the latter account for volumetric content. I then support this position with reference to how experiences of presence are created by virtual reality technologies, and end by reflecting on what this means for the relationship between sensorimotor enactivism and predictive processing.
