Sight Unseen: An Exploration of Conscious and Unconscious Vision de Melvyn Goodale

Sight Unseen: An Exploration of Conscious and Unconscious Vision

Autor Melvyn Goodale, David Milner
en Limba Engleză Hardback – 27 iun 2013

Interdisciplinaritatea este pilonul central al lucrării Sight Unseen, o explorare fascinantă care intersectează neuroștiințele, psihologia cognitivă și neuropsihologia clinică pentru a demonta mitul conform căruia vederea este un proces unitar și exclusiv conștient. Autori recunoscuți în domeniu, Melvyn Goodale și David Milner, folosesc această a doua ediție pentru a detalia modul în care creierul procesează informația vizuală prin două fluxuri separate: unul dedicat recunoașterii obiectelor și altul dedicat ghidării acțiunilor noastre în spațiu.

Considerăm că forța narativă a cărții rezidă în prezentarea cazului Dee Fletcher. Deși pacienta nu putea recunoaște forme geometrice simple sau obiecte uzuale din cauza unei leziuni cerebrale, ea putea interacționa cu acestea cu o precizie uimitoare. Remarcăm cum autorii transformă acest paradox neurologic într-o demonstrație riguroasă a existenței „vederii inconștiente”. Textul este structurat pentru a fi accesibil, evitând jargonul excesiv fără a sacrifica rigoarea științifică necesară unui volum publicat de Oxford University Press.

În contextul cursurilor de neuropsihologie, Sight Unseen reprezintă o alternativă la The Visual Brain in Action pentru studenții care caută o introducere mai narativă și mai axată pe studii de caz, având avantajul unei actualizări care integrează descoperiri recente despre plasticitatea creierului. Față de Blindsight de Lawrence Weiskrantz, care se concentrează strict pe fenomenul vederii în zonele oarbe ale câmpului vizual, lucrarea de față oferă o perspectivă mai largă asupra modului în care vedererea inconștientă funcționează în viața cotidiană a fiecăruia dintre noi.

De ce să citești această carte

Această carte este esențială pentru studenții la psihologie și medicină, dar și pentru pasionații de neuroștiințe care doresc să înțeleagă dualitatea creierului vizual. Cititorul câștigă o perspectivă clară asupra modului în care acțiunile noastre motorii sunt ghidate de mecanisme cerebrale care nu ajung niciodată în pragul conștiinței. Este o lectură care explică, prin dovezi clinice, de ce „a vedea” nu înseamnă întotdeauna „a percepe”.

Descriere

Vision, more than any other sense, dominates our mental life. Our conscious visual experience of the world is so rich and detailed that we can hardly distinguish it from the real thing. But as Goodale and Milner make clear in their prize-winning book, Sight Unseen, our visual experience of the world is not all there is to vision. Some of the most important things that vision does for us never reach our consciousness at all.In this updated and extended new edition, Goodale and Milner explore one of the most extraordinary neurological cases of recent years--one that profoundly changed scientific views on the visual brain. It is the story of Dee Fletcher--a young woman who became blind to shape and form as a result of brain damage. Dee was left unable to recognize objects or even tell one simple geometric shape from another. As events unfolded, however, Goodale and Milner found that Dee wasn't in fact blind -- she just didn't know that she could see. They showed, for example, that Dee could reach out and grasp objects with amazing dexterity, despite being unable to perceive their shape, size, or orientation. Taking us on a journey into the unconscious brain, the two scientists who made this incredible discovery tell the amazing story of their work, and the surprising conclusion they were forced to reach. Written to be accessible to students and popular science readers, this book is a fascinating illustration of the power of the 'unconscious' mind.

Recenzii

Review from previous edition Given the authors' clear and precise language and their stated aim to write an accessible book (which they achieve), this volume is a perfect Christmas present for anyone even remotely interested in the brain... Sight Unseen is not just a book for readers of popular science, demonstrating how much can be learned about brain function from patient studies; even specialists in neuroscience and neuropsychology could learn something... The book illustrates the enormous amount of knowledge to be gained from analysing deficits of specific stroke patients. It closes by stating: "Studying the way the brain reorganizes itself in response to severe damage presents one of the most important challenges to neuroscience in the twenty-first century." How true.
Goodale and Milner's book is a detailed but non-tech survey of the state of the art. There's more going on than you think, and they do an excellent job of explaining it.
Sight Unseen is an intriguing and important book, stemming as it does from beautifully observed clinical detail combined with a range of ingenious experiments. Melvyn Goodale and David Milner present a persuasive and original argument for the essential doubleness of our visual system, in writing that is vivid and often delightful. It is a valuable and fundamental contribution to our understanding of visual processing.
A rare combination of humanity and important, seminal neuroscience - masterfully accessible.
This follow-up to the authors' influential 'Visual Brain in Action' will make their important work on the 'two visual systems' more widely accessible, as it clearly deserves to be. It presents the empirical case for their seminal theory in a delightfully readable manner, treating the evolutionary basis for the dual-stream organization of the visual system, and discussing its far-reaching implications for understanding conscious and unconscious visual perception. Even those who do not agree with their entire comprehensive story will be impressed by the breadth of the case that they make for the claim that vision for action is a different, and perhaps a more primitive system of the brain than the one that gives us our conscious experience of seeing.
Sight Unseen is one of the most fascinating and engaging accounts of visual experience that I have ever read. Goodale and Milner's scientific work over the last decade has caused a revolution in perceptual neuroscience. This book explains many of the details of this revolution in a way that is accessible to interested laypeople and will be of interest to specialists as well. It also shows the warm humanity that lies at the base of every successful doctor-patient relationship. Whether you are a neuroscientist, a philosopher, a poet, a journalist, or just someone who thinks about experiences instead of merely having them, this is a book that you must read.
A rewarding book... The approach is refreshingly humane... There is much information of interest in Sight Unseen.
