The hypothesis claims that visual illusions occur because the neural circuitry in our visual system evolves, by neural learning, to a system that makes very efficient interpretations of usual 3D scenes based in the emergence of simplified models in our brain that speed up the interpretation process but give rise to optical illusions in unusual situations. In this sense, the cognitive processes hypothesis can be considered a framework for an understanding of optical illusions as the signature of the empirical statistical way vision has evolved to solve the inverse problem.<ref name="knowperc">{{cite journal |url=http://www.richardgregory.org/papers/knowl_illusion/knowledge-in-perception.pdf |title=Knowledge in perception and illusion |first=Richard L. |last=Gregory |journal=Philosophical Transactions of the Royal Society of London.

Research indicates that 3D vision capabilities emerge and are learned jointly with the planning of movements.<ref name=":0">{{Cite journal|last1=Sweet|first1=Barbara|last2=Kaiser|first2=Mary|date=August 2011|title=Depth Perception, Cueing, and Control|url=https://human-factors.arc.nasa.gov/publications/AIAA.2011.DepthPerceptionCueCntrl.pdf|journal=AIAA Modeling and Simulation Technologies Conference|publisher=NASA Ames Research Center|doi=10.2514/6.2011-6424|isbn=978-1-62410-154-0|via=American Institute of Aeronautics and Astronautics|hdl=2060/20180007277|s2cid=16425060 |hdl-access=free}}</ref> That is, as depth cues are better perceived, individuals can develop more efficient patterns of movement and interaction within the 3D environment around them.<ref name=":0" /> After a long process of learning, an internal representation of the world emerges that is well-adjusted to the perceived data coming from closer objects. The representation of distant objects near the horizon is less "adequate".{{explain|reason=What about not near the horizon?|date=March 2019}} In fact, it is not only the [[moon illusion|Moon that seems larger]] when we perceive it near the horizon. In a photo of a distant scene, all distant objects are perceived as smaller than when we observe them directly using our vision.
