interesting - to a degree
while the subject is a very interesting one, & in general presented well by Prof Vishton, there's something missing (that i just can't place). That's why i rated it a 4, & am not recommending it.

Comparing Courses about Perception
My 2013 review highly rated psychologist Frank Colavita’s 2006 Great Course “Sensation, Perception & the Aging Process”, but included a serious CON: “In Colavita's (Lecture 1 = L1): ‘Psychology accepts the principle of determinism, which is the basic assumption of all science’. This concept is wrong. Vishton, on the other hand, calls determinism ‘judgment research’ (L13) that uses ” a tiny subset of the things our senses could do”. Determinism only works well with very simplistic starting conditions, ie: Pavlov's dogs or a damaged brain. It is a tool, not a basic assumption of science. Science is the study of what is knowable about existence. It includes the Heisenberg uncertainty principle, nonlinear mathematics with positive feedback loops [part of human cellular structure], strange attractors [a primary indicator of robust systems], etc. None of these are compatible with determinism.” Vishton’s course exposes the bias of determinism. See also the Great Course: “Chaos“ by Strogatz
Viston’s course enumerates the limitations of our knowledge about human perception such as (L1’s): “80% of the neurons in the human cortex respond to visual stimuli” – a long way from grade school's determinism since most of them are nonlinearly doing other complex tasks simultaneously. EXAMPLES FOLLOW: while the color receptors see only 2% of the visual field your peripheral vision sees in color; in macular degeneration and retinitis pigmentosa gaps are filled in - making these diseases undetectable for years. His comments on the “likelihood of an action potential” passing to the second neuron suggest incredible nonlinear math. “How most of what you taste is really orthonasal olfaction” (L2) was well demonstration by Covid. L3 describes receptive aphasia: “the ability to produce but not understand speech” (one might think of this as politician’s disease?) and cautions about fMRI research. L4: the interactions of CNS subsystems to produce the mirage of perception...and cases like the man called RV.
VISHTON’S COMPLEX EXAMPLES ALSO INCLUDE: (L4-L15) atmospheric perspective; quadcromatic vision; color constancy; color mixing vs painting; why fluorescent and tungsten green lights are not perceived that way; habitat and age flavor shifts; how your eyes convey hot peppers’ heat; the ear’s application of Fourier transformations for frequency separation; the ear’s sensitivity of less than a decibel for human speech; ear pinnae are designed for 3 specific location problems; why we use transitional probabilities while seeing and hearing speech; the thermal grill illusion; inferred “outside of the body” experiences; non-medical approaches and indirect pain perception; that the CNS ventral stream control of our conscious visual interpretation is influenced by illusions but the dorsal stream for visually guided actions isn’t; inattention blindness (except for changes in environmental replacement by persons of different sex, age, color); why the hip contracts before you reach for something; motion illusions with dim alarm clocks explained; the amazing hearing of the unborn and their motor pre-programming or as L16 puts it: “they come into this world able to see, hear, smell, taste, feel, and their reasoning is more impressive than one might imagine”; (L17) “smiling alone requires the selective contraction of 17 different muscles” as well as facial recognition by infants; L18 illusions explained including making goats appear out of nowhere; L19 height perception dependence on danger cues; how to beat a polygraph; ‘microexpressions’; ESP; L21: the nerve ganglion’s lateral inhibiting opponent processing of color processing; aftereffects, edges, caffeine, light/dark boundaries risky behavior; L22 the amazing synesthete, i.e.: uniquely cross-wired perceptions (8x female:male and 50% lefties) who taste color and see sound; why “I don’t know, I’m just sure of it” is critical in police line-ups; L24 tongue based TV and blind children with echolocation.
SUMMARY: Viston’s Guidebook is nearly a Transcript. His bio contains his modus operandi: “He has found…that the nature of sensory processing is altered by the actions we chose to perform. In essence, our intention to act on something changes how we perceive it.” Complexity theory supports Vishton’s ”…no specific detailed scientific theory can ever fully explain and test the brain’s workings (L4).” That “your brain infers a lot of detail and fills it in (L7)” supports Plato's affirmation [Great Course: Fall of Pagans_Harl, L5] that the body governed is by the will of the soul. Vishton denies university-imposed Determinism and threatens the medieval [Great Course: Late Middle Ages_Daileader, “Scope"] concept of Humanism.

Informative, Thought Provoking
This is one of the best of many Great Courses that I have viewed. The material is well-organized, and delivered in a well-structured smooth way by Vishton, an excellent speaker.
Humans have an amazing perceptual system that can be trained to assist us in perceiving the world around us on the flyI as our senses record the world around us. I had no idea such a processing capability was operating behind the awareness of our conscious mind..
I have macular degeneration, and found explanation of my experience that I have found nowhere else.
I highly recommend this course.

Very Interesting and Outstanding Presentation
Absolutely fascinating from start to finish and Professor Vishton is an outstanding speaker. Professionally, I'm an engineer by trade, so I wasn't too sure about this topic. However, since I'm a human, too, it turns out that it was totally applicable. I would probably have titled the course the Wonders of Human Perception rather than the Secrets, because gaining some insight into perception was wonder-full. I think anyone would enjoy this and benefit from it.
Professor Vishton's presentation style was so pleasant and captivating, that I will surely consider his other courses.
Like many other Great Courses, I highly recommend the video version as too much would be lost using only audio.

Perception Explored
This is an excellent course, lucid and well illustrated with fascinating examples. Sometimes it glosses over subjects and oversimplifies certain aspect of detail, but as an introduction to the topic this is no bad thing and is not a problem. The professor is easy to follow and comes across well. This is one of the few courses I have done where I am
always tempted to go on to the next lecture, regardless of the time! A real page turner, but it is playing havoc with my bedtime.

Needs a warning -
A number of the lectures have visual effects that can be dangerous to people with certain medical conditions - and there is NO WARNING about them. Also this series could have been done in half the time, presenter repeats him so much.
