Unconscious Memory Representations in Perception


Book Description

Perceptual experience emerges from neural computations. "Unconscious Memory Representations in Perception "focuses on the role of implicit (non-conscious) memories in processing sensory information. Making sense of the wealth of information arriving at our senses requires implicit memories, which represent environmental regularities, contingencies of the sensory input, as well as general contextual knowledge. Recent findings and theories in cognitive and computational neuroscience provided new insights into the structure and contents of implicit memory representations. The chapters of this book examine implicit memories both in relatively simple situations, such as perceiving auditory and visual objects, as well as in high?level cognitive functions, such as speech and music perception and aesthetic experience. By nature, implicit memories cannot be directly studied with behavioral methods. Therefore, a large part of the evidence reviewed was obtained in neuroscientific studies. Readers with limited experience in neuroscience will find information about the most commonly used techniques in the appendix of this volume. (Series B)




Consciousness Emerging


Book Description

This study of the workings of neural networks in perception and understanding of situations and simple sentences shows that, and how, distributed conceptual constituents are bound together in episodes within an interactive/dynamic architecture of sensorial and pre-motor maps, and maps of conceptual indicators (semantic memory) and individuating indicators (historical, episodic memory). Activation circuits between these maps make sensorial and pre-motor fields in the brain function as episodic maps creating representations, which are expressions in consciousness. It is argued that all consciousness is episodic, consisting of situational or linguistic representations, and that the mind is the whole of all conscious manifestations of the brain. Thought occurs only in the form of linguistic or image representations. The book also discusses the role of consciousness in the relationship between causal and denotational semantics, and its role for the possibility of representations and rules. Four recent controversies in consciousness research are discussed and decided along this model of consciousness: • Is consciousness an internal or external monitoring device of brain states? • Do all conscious states involve thought and judgement? • Are there different kinds of consciousness? • Do we have a one-on-one correspondence between certain brain states and conscious states. The book discusses also the role of consciousness in the relationship between causal and denotational semantics, and its role for the possibility of representations and rules. (Series A)




Olfactory Cognition


Book Description

This book was conceived as a tribute to one of the founders of the psychological study of the sense of smell, Professor Trygg Engen. The book is divided into four sections. The first reunites the fields of psychophysics and the perception of environmental odours and discusses the impact of odours on beliefs and expectations. The second addresses cognitive processes in olfaction, how odours are interpreted, lexicalized, associated with contexts and remembered. The third focuses on the cerebral bases of olfactory awareness and the neuropsychological investigation of olfaction with special emphasis on olfactory dysfunctions, and the last concerns affective and developmental processes in olfaction. The aim in producing this book is that it will help promote further research in olfactory cognition and attract new inquisitive scientists to the field. The volume will be a useful resource for academics, students, and professionals who study olfaction, as well as to scientists who work in the domains of perception, cognitive neuroscience and environmental psychology more broadly.




Perception Without Awareness


Book Description

This landmark volume brings together the work of the world's leading researchers in sublimated perception. This compilation marks a fundamental shift in the current study of subliminal effects: No longer in question is the notion that perception without awareness occurs. Now, the emphasis is on elucidating the parameters of subliminal effects and understanding the conditions under which stimuli perceived without awareness significantly influence affect, cognition, and behavior. PERCEPTION WITHOUT AWARENESS firmly establishes subliminal perception within the mainstream of psychological science. Well represented here are the two main research branches that have emerged: One directly investigates the nature of subliminal effects; the other uses subliminal techniques as tools for investigating psychological phenomena such as hypnosis, dreaming, repression, social judgment and inference, psychopathology, and symptom formation. Broadly grouped into three main sections, the contributed chapters explore * The cognitive perspective--including implicit memory and implicit perception, the measurement of unconscious perceptual processes, and methods for revealing unconscious processes * The clinical perspective--exploring the cognitive and dynamic aspects of subliminal perception, memory, and consciousness; direct recovery of subliminal stimuli; and validation of subliminal psychodynamic activation * The social perspective--discussing subliminal mere-exposure effects, affect and social perception, and the role of subliminality in social psychology Timely and thought-provoking, PERCEPTION WITHOUT AWARENESS is sure to be of enormous interest to all psychoanalytic clinicians and scholars, as well as cognitive, clinical, and social psychologists whose work touches upon issues relating to psychopathology, perception, cognition, and memory.




Attention, Perception and Memory


Book Description

Although attention, perception and memory are identifiable components of the human cognitive system, this book argues that for a complete understanding of any of them it is necessary to appreciate the way they interact and depend on one another. Using close examination of experiments, studies of patients and evidence from cognitive neuroscience, each of these important areas in cognitive psychology is explored in detail and related to its counterparts. Written by an established author, Attention, Perception and Memory: An Integrated Introduction explains clearly the evolution and meaning of key terminology and assumptions and puts the different approaches to this field in context.




From Perception to Consciousness


Book Description

This volume includes seminal articles published throughout Anne Treisman's scientific career, which are accompanied by chapters from key figures in the field today. These demonstrate the breadth and depth of her influence on research and theory from psychology to vision and auditory sciences.




Discovering the Brain


Book Description

The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."




Consciousness and the Brain


Book Description

WINNER OF THE 2014 BRAIN PRIZE From the acclaimed author of Reading in the Brain and How We Learn, a breathtaking look at the new science that can track consciousness deep in the brain How does our brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before. In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events behind a conscious state. We can now pin down the neurons that fire when a person reports becoming aware of a piece of information and understand the crucial role unconscious computations play in how we make decisions. The emerging theory enables a test of consciousness in animals, babies, and those with severe brain injuries. A joyous exploration of the mind and its thrilling complexities, Consciousness and the Brain will excite anyone interested in cutting-edge science and technology and the vast philosophical, personal, and ethical implications of finally quantifying consciousness.




Event Cognition


Book Description

Much of our behavior is guided by our understanding of events. We perceive events when we observe the world unfolding around us, participate in events when we act on the world, simulate events that we hear or read about, and use our knowledge of events to solve problems. In this book, Gabriel A. Radvansky and Jeffrey M. Zacks provide the first integrated framework for event cognition and attempt to synthesize the available psychological and neuroscience data surrounding it. This synthesis leads to new proposals about several traditional areas in psychology and neuroscience including perception, attention, language understanding, memory, and problem solving. Radvansky and Zacks have written this book with a diverse readership in mind. It is intended for a range of researchers working within cognitive science including psychology, neuroscience, computer science, philosophy, anthropology, and education. Readers curious about events more generally such as those working in literature, film theory, and history will also find it of interest.




Introduction to Psychology


Book Description

This book is designed to help students organize their thinking about psychology at a conceptual level. The focus on behaviour and empiricism has produced a text that is better organized, has fewer chapters, and is somewhat shorter than many of the leading books. The beginning of each section includes learning objectives; throughout the body of each section are key terms in bold followed by their definitions in italics; key takeaways, and exercises and critical thinking activities end each section.
