Effects of Expectation on Visual Object Processing in Humans
Author: Amrita Monica PuriTouch and Blindness
Author: Morton A. HellerPublisher: Psychology Press
ISBN: 1135619301
Category : Psychology
Languages : en
Pages : 395
Book Description
Research on touch and blindness has undergone rapid transformation in recent years, with dramatic developments in technology designed to provide assistance to those who are blind, and advancements in robotics that demand haptic interfaces. Touch and Blindness approaches the study of the topic from the perspectives of psychological methodology and the most sophisticated, state-of-the-art techniques in neuroscience. This book, edited by well-known leaders in the field, is derived from the discussions presented by speakers at a conference held in 2002, and presents current research in the field. The book is arranged in a logical, disciplinary fashion, first discussing touch and blindness from a psychological perspective, followed by an examination from the perspective of neuroscience. Some specific topics include: *processing spatial information from touch and movement; *form, projection, and pictures for the blind; *neural substrate and visual and tactile object representations; and *the role of visual cortex in tactile processing. Touch and Blindness is ideal for researchers in psychology and neuroscience, medicine, and special education.

A Case Study in Visual Agnosia Revisited
Author: Glyn HumphreysPublisher: Psychology Press
ISBN: 1136766960
Category : Psychology
Languages : en
Pages : 165
Book Description
Visual agnosia is a rare but fascinating disorder of visual object recognition that can occur after a brain lesion. This book documents the case of John, who worked intensively with the authors for 26 years after acquiring visual agnosia following a stroke. It revisits John’s case over twenty years after it was originally described in the book To See But Not To See, in 1987. As in the previous book, the condition is illuminated by John and his wife, Iris, in their own words. A Case Study in Visual Agnosia Revisited discusses John’s case in the context of research into the cognitive neuroscience of vision over the past twenty years. It shows how John’s problems in recognition can provide important insights into the way that object recognition happens in the brain, with the results obtained in studies of John’s perception being compared to emerging work from brain imaging in normal observers. The book presents a much fuller analysis of the variety of perceptual problems that John experienced, detailing not only his impaired object recognition but also his face processing, his processing of different visual features (colour, motion, depth), his ability to act on and negotiate his environment, and his reading and writing. A Case Study in Visual Agnosia Revisited will be a key reference for those concerned with understanding how vision is implemented in the brain. It will be suitable for both undergraduate students taking courses in cognitive psychology and neuropsychology, and also researchers in the cognitive neuroscience of vision. The presentation of John’s case, and the human aspects of the disorder, will also be of great interest to a general audience of lay people interested in perception.
Visual Mismatch Negativity (vMMN): a Prediction Error Signal in the Visual Modality
Author: Gabor StefanicsPublisher: Frontiers Media SA
ISBN: 2889195600
Category : Neurosciences. Biological psychiatry. Neuropsychiatry
Languages : en
Pages : 204
Book Description
Current theories of visual change detection emphasize the importance of conscious attention to detect unexpected changes in the visual environment. However, an increasing body of studies shows that the human brain is capable of detecting even small visual changes, especially if such changes violate non-conscious probabilistic expectations based on repeating experiences. In other words, our brain automatically represents statistical regularities of our visual environmental. Since the discovery of the auditory mismatch negativity (MMN) event-related potential (ERP) component, the majority of research in the field has focused on auditory deviance detection. Such automatic change detection mechanisms operate in the visual modality too, as indicated by the visual mismatch negativity (vMMN) brain potential to rare changes. VMMN is typically elicited by stimuli with infrequent (deviant) features embedded in a stream of frequent (standard) stimuli, outside the focus of attention. In this research topic we aim to present vMMN as a prediction error signal. Predictive coding theories account for phenomena such as mismatch negativity and repetition suppression, and place them in a broader context of a general theory of cortical responses. A wide range of vMMN studies has been presented in this Research Topic. Twelve articles address roughly four general sub-themes including attention, language, face processing, and psychiatric disorders. Additionally, four articles focused on particular subjects such as the oblique effect, object formation, and development and time-frequency analysis of vMMN. Furthermore, a review paper presented vMMN in a hierarchical predictive coding framework. Each paper in this Research Topic is a valuable contribution to the field of automatic visual change detection and deepens our understanding of the short term plasticity underlying predictive processes of visual perceptual learning.

Pages : 237
Book Description
“As David Robson makes plain in this compelling book, the way we think about the world can profoundly shape how we navigate it. Based in science and packed with smart advice, The Expectation Effect will expand your mind—and maybe even extend your life.” —Daniel Pink, New York Times bestselling author of When, Drive, and To Sell Is Human A journey through the cutting-edge science of how our mindset shapes every facet of our lives, revealing how your brain holds the keys to unlocking a better you What you believe can make it so. You’ve heard of the placebo effect and how sugar pills can accelerate healing. But did you know that sham heart surgeries often work just as well as placing real stents? Or that people who think they’re particularly prone to cardiovascular disease are four times as likely to die from cardiac arrest? Such is the power and deadly importance of the expectation effect—how what we think will happen changes what does happen. Melding neuroscience with narrative, science journalist David Robson takes readers on a deep dive into the many life zones the expectation effect permeates. We see how people who believe stress is beneficial become more creative when placed under strain. We see how associating aging with wisdom can add seven plus years to your life. People say seeing is believing but, over and over, Robson proves that the converse is truer: believing is seeing. The Expectation Effect is not woo-woo. You cannot think your way into a pile of money or out of a cancer diagnosis. But just because magical thinking is nonsense doesn’t mean rational magic doesn’t exist. Pointing to accepted psychology and objective physiology, Robson gives us the practical takeaways we need to improve our fitness, productivity, intelligence, and happiness. Any reader who wants to take their fate into their own hands need only pick up this book.

The Cambridge Handbook of Applied Perception Research
Author: Robert R. HoffmanPublisher: Cambridge University Press
ISBN: 1139993534
Category : Psychology
Languages : en
Pages : 1468
Book Description
The Cambridge Handbook of Applied Perception Research covers core areas of research in perception with an emphasis on its application to real-world environments. Topics include multisensory processing of information, time perception, sustained attention, and signal detection, as well as pedagogical issues surrounding the training of applied perception researchers. In addition to familiar topics, such as perceptual learning, the Handbook focuses on emerging areas of importance, such as human-robot coordination, haptic interfaces, and issues facing societies in the twenty-first century (such as terrorism and threat detection, medical errors, and the broader implications of automation). Organized into sections representing major areas of theoretical and practical importance for the application of perception psychology to human performance and the design and operation of human-technology interdependence, it also addresses the challenges to basic research, including the problem of quantifying information, defining cognitive resources, and theoretical advances in the nature of attention and perceptual processes.
The Predictive Mind
Author: Jakob HohwyPublisher: OUP Oxford
ISBN: 0191022616
Category : Philosophy
Languages : en
Pages : 296
Book Description
A new theory is taking hold in neuroscience. It is the theory that the brain is essentially a hypothesis-testing mechanism, one that attempts to minimise the error of its predictions about the sensory input it receives from the world. It is an attractive theory because powerful theoretical arguments support it, and yet it is at heart stunningly simple. Jakob Hohwy explains and explores this theory from the perspective of cognitive science and philosophy. The key argument throughout The Predictive Mind is that the mechanism explains the rich, deep, and multifaceted character of our conscious perception. It also gives a unified account of how perception is sculpted by attention, and how it depends on action. The mind is revealed as having a fragile and indirect relation to the world. Though we are deeply in tune with the world we are also strangely distanced from it. The first part of the book sets out how the theory enables rich, layered perception. The theory's probabilistic and statistical foundations are explained using examples from empirical research and analogies to different forms of inference. The second part uses the simple mechanism in an explanation of problematic cases of how we manage to represent, and sometimes misrepresent, the world in health as well as in mental illness. The third part looks into the mind, and shows how the theory accounts for attention, conscious unity, introspection, self and the privacy of our mental world.
