MOBI J. Kevin O'Regan ↠ MOBI Why Red Doesnt Sound Like a Bell Epub µ Doesnt Sound ↠ multi channel.co

This book proposes a novel view to explain how we as humans contrary to current robots can have the impression of consciously feeling things for example the red of a sunset the smell of a rose the sound of a symphony or a pain The book starts off by looking at visual perception Our ability to see turns out to be much mysterious than one might think The eye contains many defects which should seriously interfere with vision Yet we have the impression of seeing the world in glorious panavision and technicolor Explaining how this can be the case leads to a new idea about what seeing really is Seeing is not passively receiving information in the brain but rather a way of interacting with the world The role of the brain is not to create visual sensation but to enable the necessary interactions with the world This new approach to seeing is extended in the second part of the book to encompass the other senses hearing touch taste and smell Taking sensory experiences to be modes of interacting with the world explains why these experiences are different in the way they are It also explains why thoughts or automatic functions in the body and indeed the vast majority brain functions are not accompanied by any real feeling The sensorimotor approach is not simply a philosophical argument It leads to scientifically verifiable predictions and new research directions Among these are the phenomena of change blindness sensory substitution looked but failed to see as well as results on color naming and color perception and the localisation of touch on the body The approach is relevant to the uestion of what animals and babies can feel and to understanding what will be necessary for robots to become conscious

    Research psychology presented at it's best O'Regan is one of a modern crop of psychologists and philosophers who favour the idea that consciousness or 'cognition is based not just in the brain but 'out' in the world too There are 4 variations of this embodied embedded extended and enacted see Mark Rowlands The New Science of MindRagan however is a research psychologist not a philosopher so he is presenting actual research and it's results and this is very refreshing in the world of cognitive science In a bright and breezy style full of concrete examples and actual testing he shows how cognition is built up from the outside first Currently 2018 the book is available for free download from the author's website so a big thumbs up for that

    A year ago I had the privilege to attend a lecture by J Kevin O’Regan ex director of the Laboratoire de Psychologie de la Perception at the Université René Descartes Paris 5 In his book Why Red doesn’t sound like a bell J Kevin O’Regan writes about consciousness and feel in a new way The first part is about the feel of seeingWhy do we think we see “everything” in front of us whereas our eyes are not that good? Is it because the brain provides us with a fully corrected representation? No J Kevin O’Regan saysI wrote a lengthy article about the first part here

    I'd recommend the first 25% of this book to anyone doing computer vision research It highlights the limitations of doing research in the context of narrow single task learning rather than an embodied system trying to learn about the world In this way ORegan makes a strong case for the necessity of embodiment for developing AGI or any system that hopes of understanding the visual worldORegan begins by narrating an old age paradox in the mechanics of biological eyes images are projected inverted on the neurons that carry signal to the brain why do we perceive the world right side up?He describes the spectre of the homolocus that has plagued scientific thinking in resolving this apparent paradox Basically it boils down to whether the inversion is corrected in pixel space or latent space Scientists who believed in the Cartesian theatre that is to say images from the eyes are physically projected right side up in a region of the brain and is interpreted by a little man in the brain were essentially arguing for pixel space correction This is almost certainly wrongORegan points out numerous other mechanical flaws with the human eyes photo receptors are mostly concentrated in the middle of the eye color focus and resolution focus cannot be simultaneously achieved the eye is curved and straight lines are projected as curved there are blind spots there is object continuity when we perform faccades with our eyesThe all share the property that scientists tried to explain the apparent disconnect between noisy input image and noiseless perceived visual world by pixel space adjustmentIt's ironic that each of these apparent flaws with the human eyes have a pixel space correction in computer vision research In the same order they are super resolution colorization mapping of lanes in self driving for example in filling composing seuences of images in videoThe thesis ORegan presents is that none of these adjustments are made in the human visual system In other words if we are hoping to build self driving systems for example by composing a series of single task pixel level corrections to what the camera captures then we are almost certainly doing it wrong or at least different from how human perception worksORegan goes on to present a unifying framework to describe vision touch memory and imagination He views each of these as an iterative attention process whereby the mind observes both an immediately relevant high res detail and caches some peripheral low res information for further exploration This iterative process is grounded in the goals of the human and in this sense the reward is backpropagated all the way back from goals rather than a single imagevision tasksI personally like the elegance of such a unifying theory but would caution in making oversimplifications in understanding the brainHe describes how this iterative attention mechanism explains the perceived stability of human vision Spatial stability or the sense of knowing everything in the room is achieved by the very ability to see everything in the room by caching low resolution information to prompt future attention Temporal stability or the sense of always keeping an eye on something even when you're blinking or distracted is achieved by a confirmation bias Do I still see the cat? Attend on cat YesI'd also go on to say there is a sanity bias human's subjective experience is consonant with an expectation of being sayOf course I am continually looking at the catOf course making new memories don't delete old onesI think the main conclusion in this book is subtle but very startling The subjective experience of seeing something is nothing but the decoding of neural signal by other neurons in the brain This seems directly at odds with the high resolution or subjective visual experience Why do we not see the branches and leaves of the tree as a green and brown blob? Or why does a tree not appear as an elephant? Why does neurons firing conjure a subjective experience of seeing the outside world that is accurate with respect to the objectsthings in the outside world?One hypothesis is survival A lot of neurons are dedicated to visual processing perhaps because having high accuracy and resolution is necessary to survive eat mushroom A but not mushroom B don't mistake a lion for a gazelleAnother hypothesis is sanity bias We like to think we are seeing objects for exactly how they are when in reality a higher resolution experience is possible At the end of the day we have no reference to judge what subjective experience should be likeOne way to test the hypothesis that seeing is only the firing of neurons is to apply a well design electrical signal to a person's brain The hypothesis implies we can modify subjective experience by modifying how neurons fireThe latter parts of the book are as disappointing as the firsts were refreshing It reads like a watered down version of GEB The dialogue is unfocused There is a noticeable shift of narrative style to using hyperbolic adjectives and verbs as the substance in the book decreases ORegan's ideas on consciousness are outdated and cliche A chess playing robot is not conscious because it can't talk about the weather

    Found the book hard to read and difficult to finish till the end but the new concept of feel as sensor motor interaction with the world really interesting The idea is similar to the idea of feeling at home When I am sitting on my sofa I feel at home because there are a variety of actions I can undertake go into the kitchen and get a coffee; go to the bedroom and lie down; etc But I need not undertake them It is because I'm poised to do these things that I have the feeling of being at home Feeling at home does not reuire actual action In the same way seeing does not reuire actual action It reuires having previously acted and it reuires having the future potential for action

    Consciousness isn't one thing That's part of the problem with that term it means different things to different people and there are different components of it There is a concept of self awareness that's an easy one to explain at least The challenging part of consciousness is what is referred to as ualia which deals with individual instances of subjective conscious experience Like for example how you perceive an object that seems red or what is pain or what does pain feel like That to me seems like a far interesting aspect of consciousness And this is by far the best treatise I've read about that particular component of consciousness it's a difficult read But very insightful

    This is an incredibly concise and concrete explanation of feeling and consciousness I'm amazed at how much is covered in this book and how clearly it's explained The Notes for each Chapter are also uite helpful Really great job

    o'regan's one of my favorite cognitive scientists the only reason i haven't read it yet is that i've read a bunch of his papers already and i had to stop and read about retinasi'm really looking forward to it though
