Thought Extramission: The Eyes Project Conceptual Maps at Close Distance

Abstract

Light extramission is a popular yet erroneous model of human vision positing that light projects through the eyes over surrounding objects, allowing them to become visible. However, light extramission research has failed to distinguish between light and other types of emissions coming from the eyes, thereby discounting the possibility that extramission mechanisms might hold true for phenomena other than light. Here, we explored the thought extramission model, which is the notion that thoughts emanate from the eyes in the form of visualized representations. We show that the eyes project thoughts a short distance away in the form of high-resolution conceptual maps whose structure collapses at great distances. We also demonstrate that sensory filtering of thought projection by reducing light contrast lowers the resolution of conceptual maps. Our results highlight the supporting role of the visual system for thought processes relying on contrast, luminance, and perspective formation.
