Dialogues on Perception by Bela Julesz

By Bela Julesz

Popular for his paintings extensive belief and development acceptance, Bela Julesz originated the techniques--involving computer-generated random-dot stereograms, cinematograms, and textures--that ended in the subfield of human psychology known as "early vision." during this ebook, Julesz elucidates the information and insights generated via this interesting paradigm in a chain of dialogues among Julesz the naif and Julesz the scientist. those playful, own, deeply educated dialogues, notwithstanding not easy, are by no means past the succeed in of the final clinical reader drawn to mind study. one of the issues coated are stereopsis, movement belief, neurophysiology, texture and auditory belief, early imaginative and prescient, visible cognition, and desktop imaginative and prescient. Julesz's paintings on early imaginative and prescient and focal recognition is the root of the discussions, yet he's both comfy recounting his debate with John Searle and describing his interactions with Salvador Dali. He additionally addresses creativity, arithmetic, theories, metascientific questions, maturational home windows, and cortical plasticity, relates his present paintings to prior findings and concepts, and considers how a few strategic questions could be solved with present instruments.

B: In FCP you devoted an entire chapter to Klein's Erlangen program and its relations to mental geometries. Have you changed your views, since you have not referred to these ideas so far in our discussion? A: Thanks for reminding me. The mathematician Felix Klein proposed a program to study geometries by searching for invariances under given transformations. In FCP I mentioned an interesting proposal by William Hoffman (1966) to study visual perception by means of Lie algebras (Lie 1893). In the 25 years since I wrote that chapter, Hoffman (1970) extended his method to infinitesimal Lie transforms, called Lie germs, and called it the Lie Transformation Group Model in Neuropsychology (LTG/NP).

What does matter is the insight that primitive features exist, and that they selectively trigger early filters. ] The extraction of textons occurs at such an early stage in the central nervous system that neither consciousness nor top-down processes can reach them, and thus their primitiveness is preserved. Only to these simplifying conditions, below the level of conscious awareness, can we apply some rules that behave like axioms, and begin to link one texton with another without having to describe what textons are in isolation.

Similarly, it is a mistake to give a psychological primitive a perceptual existence of its own; instead, one must define it by its relations to other primitives. The belief that psychological percepts could be directly sensed misled psychologists for centuries. Somehow, they thought, psychological primitives must be defined in themselves, and hence must be consciously perceivable entities. In order to pursue this basic idea further, let us take trichromacy, perhaps the only Euclidean theory of psychology.
