Available in PDF, EPUB and Kindle. Book excerpt: 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)

Download or read book Perception Without Awareness written by Robert F. Bornstein and published by Guilford Publication. This book was released on 1992 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Electrophysiological Correlates of the Influences of Past Experience on Conscious and Unconscious Figure Ground Perception written by Logan Thomas Trujillo and published by . This book was released on 2007 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Figure-ground perception can be modeled as a competitive process with mutual inhibition between shape properties on opposite sides of an edge. This dissertation reports brain-based evidence that such competitive inhibition can be induced by access to preexisting object memory representations during figure assignment. Silhouette stimuli were used in which the balance of properties along an edge biased the inner, bounded, region to be seen as a novel figure. Experimental silhouettes (EXP) suggested familiar objects on their outside edges, which nonetheless appeared as shapeless grounds. Control silhouettes (CON) suggested novel shapes on the outside. In an initial task, human observers categorized masked EXP and CON silhouettes (175 ms exposure) as"novel"versus a third group of silhouettes depicting"familiar"objects on the inside. Signal detection measures verified that observers were unconscious of the familiar shapes within the EXP stimuli. Across three experiments, novel categorizations were highly accurate with shorter RTs for EXP than CON. Event-related potential (ERP) indices of observers' brain activity (Experiments 2 and 3) revealed a Late Potential (3̃00 ms) to be less positive for EXP than CON, a reduction in neural activity consistent with the presence of greater competitive inhibition for EXP stimuli. After controlling for stimulus confounds (Experiment 3), the P1 ERP (1̃00 ms) was larger for EXP than CON conditions, perhaps reflecting unconscious access to object memories. In a second task, observers were informed about familiar shapes suggested on the outsides of the EXP silhouettes before viewing masked (Experiments 1 and 2) or unmasked (Experiment 3) EXP and CON silhouettes to report whether they saw familiar shapes on the outside. Experiment 3 observers were more accurate to categorize CON vs. EXP stimuli as novel vs. familiar, with shorter RTs for EXP than CON. Task 2 N170 ERPs (1̃70 ms) were larger for EXP than CON in Experiments 2 and 3, reflecting the conscious perception of familiar shape in the outsides of EXP silhouettes. LP magnitudes were greater for CON than EXP, although ERP polarity was dependent on the presence/absence of a mask. Task 2 LPs may reflect competitive inhibition or longer processing times for CON stimuli.

Download or read book Perception First Form of Mind written by Tyler Burge and published by Oxford University Press. This book was released on 2022-05-13 with total page 897 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In Perception: First Form of Mind, Tyler Burge develops an understanding of the most primitive type of representational mind: perception. Focusing on its form, function, and underlying capacities, as indicated in the sciences of perception, Burge provides an account of the representational content and formal representational structure of perceptual states, and develops a formal semantics for them. The account is elaborated by an explanation of how the representational form is embedded in an iconic format. These structures are then situated in current theoretical accounts of the processing of perceptual representations, with an emphasis on the formation of perceptual categorizations. An exploration of the relationship between perception and other primitive capacities-conation, attention, memory, anticipation, affect, learning, and imagining-clarifies the distinction between perceiving, with its associated capacities, and thinking, with its associated capacities. Drawing on a broad range of historical and contemporary research, rather than relying on introspection or ordinary talk about perception, Perception: First Form of Mind is a scientifically rigorous and agenda-setting work in the philosophy of perception and the philosophy of science"--

Available in PDF, EPUB and Kindle. Book excerpt: "What is the difference between seeing and thinking? Is the border between seeing and thinking a joint in nature in the sense of a fundamental explanatory difference? Is it a difference of degree? Does thinking affect seeing, i.e. is seeing "cognitively penetrable"? Are we aware of faces, causation, numerosity and other "high-level" properties or only of the colors, shapes and textures that-according to the advocate of high level perception--are the basis on which we see them? Is perception conceptual and propositional? Is perception iconic or more akin to language in being discursive? Is seeing singular? Which is more fundamental, visual attribution or visual discrimination? Is all seeing seeing-as? What is the difference between the format and content of perception and do perception and cognition have different formats? Is perception probabilistic and if so, why are we not normally aware of this probabilistic nature of perception? Are the basic features of mind known as "core cognition" a third category in between perception and cognition? Are there perceptual categories that are not concepts? Where does consciousness fit in with regard to the difference between seeing and thinking? Do the lessons from seeing apply to other senses? These are the questions I will be exploring in this book. I will be exploring them not mainly by appeals to "intuitions" as is common in philosophy of perception but by appeal to empirical evidence, including experiments in neuroscience and psychology"--

All contain new ideas on the topics covered; together they demonstrate the vigour and innovative zeal of a young field. The book is accessible to anybody who has an intellectual interest in issues concerning perception.
Download or read book Psychoanalysis and the Time of Life written by Jan Campbell and published by Routledge. This book was released on 2007-03-12 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is psychoanalysis a narrative of self-knowledge, or a movement of lived time and the body? Psychoanalysis and the Time of Life examines the relationship between therapy and the time of life, presenting an original and thought-provoking re-reading of psychoanalysis in relation to questions of lived time. Jan Campbell investigates the early work of Freud, Janet, Breuer and Ferenczi, linking their ideas to the philosophy of Bergson. The link between psychoanalysis and the question of time connects these early debates with current issues that are central to our global society. Questions considered include: • is the unconscious based on representation or affect? • is the Oedipal Complex hysterical? • how is therapy related to the time of our life? • what is the role of hypnosis, in relation to psychoanalytic theory and transference? • Freud conceptualised the unconscious as timeless space, but what would it mean to think of the unconscious as the very essence of psychic bodily time? This book draws on the fields of traditional psychoanalysis, philosophy, neuroscience, and trauma studies providing a valuable new perspective on familiar concepts such as identity and consciousness. It will be of interest to students across the humanities and social sciences, and practicing psychoanalysts and psychoanalytic psychotherapists.

Download or read book The Age of Insight written by Eric Kandel and published by Random House. This book was released on 2012-03-27 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brilliant book by Nobel Prize winner Eric R. Kandel, The Age of Insight takes us to Vienna 1900, where leaders in science, medicine, and art began a revolution that changed forever how we think about the human mind—our conscious and unconscious thoughts and emotions—and how mind and brain relate to art. At the turn of the century, Vienna was the cultural capital of Europe. Artists and scientists met in glittering salons, where they freely exchanged ideas that led to revolutionary breakthroughs in psychology, brain science, literature, and art. Kandel takes us into the world of Vienna to trace, in rich and rewarding detail, the ideas and advances made then, and their enduring influence today. The Vienna School of Medicine led the way with its realization that truth lies hidden beneath the surface. That principle infused Viennese culture and strongly influenced the other pioneers of Vienna 1900. Sigmund Freud shocked the world with his insights into how our everyday unconscious aggressive and erotic desires are repressed and disguised in symbols, dreams, and behavior. Arthur Schnitzler revealed women’s unconscious sexuality in his novels through his innovative use of the interior monologue. Gustav Klimt, Oscar Kokoschka, and Egon Schiele created startlingly evocative and honest portraits that expressed unconscious lust, desire, anxiety, and the fear of death. Kandel tells the story of how these pioneers—Freud, Schnitzler, Klimt, Kokoschka, and Schiele—inspired by the Vienna School of Medicine, in turn influenced the founders of the Vienna School of Art History to ask pivotal questions such as What does the viewer bring to a work of art? How does the beholder respond to it? These questions prompted new and ongoing discoveries in psychology and brain biology, leading to revelations about how we see and perceive, how we think and feel, and how we respond to and create works of art. Kandel, one of the leading scientific thinkers of our time, places these five innovators in the context of today’s cutting-edge science and gives us a new understanding of the modernist art of Klimt, Kokoschka, and Schiele, as well as the school of thought of Freud and Schnitzler. Reinvigorating the intellectual enquiry that began in Vienna 1900, The Age of Insight is a wonderfully written, superbly researched, and beautifully illustrated book that also provides a foundation for future work in neuroscience and the humanities. It is an extraordinary book from an international leader in neuroscience and intellectual history.
Download or read book Language and Cognition written by Kuniyoshi L. Sakai and published by Frontiers Media SA. This book was released on 2015-07-07 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interaction between language and cognition remains an unsolved scientific problem. What are the differences in neural mechanisms of language and cognition? Why do children acquire language by the age of six, while taking a lifetime to acquire cognition? What is the role of language and cognition in thinking? Is abstract cognition possible without language? Is language just a communication device, or is it fundamental in developing thoughts? Why are there no animals with human thinking but without human language? Combinations even among 100 words and 100 objects (multiple words can represent multiple objects) exceed the number of all the particles in the Universe, and it seems that no amount of experience would suffice to learn these associations. How does human brain overcome this difficulty? Since the 19th century we know about involvement of Broca’s and Wernicke’s areas in language. What new knowledge of language and cognition areas has been found with fMRI and other brain imaging methods? Every year we know more about their anatomical and functional/effective connectivity. What can be inferred about mechanisms of their interaction, and about their functions in language and cognition? Why does the human brain show hemispheric (i.e., left or right) dominance for some specific linguistic and cognitive processes? Is understanding of language and cognition processed in the same brain area, or are there differences in language-semantic and cognitive-semantic brain areas? Is the syntactic process related to the structure of our conceptual world? Chomsky has suggested that language is separable from cognition. On the opposite, cognitive and construction linguistics emphasized a single mechanism of both. Neither has led to a computational theory so far. Evolutionary linguistics has emphasized evolution leading to a mechanism of language acquisition, yet proposed approaches also lead to incomputable complexity. There are some more related issues in linguistics and language education as well. Which brain regions govern phonology, lexicon, semantics, and syntax systems, as well as their acquisitions? What are the differences in acquisition of the first and second languages? Which mechanisms of cognition are involved in reading and writing? Are different writing systems affect relations between language and cognition? Are there differences in language-cognition interactions among different language groups (such as Indo-European, Chinese, Japanese, Semitic) and types (different degrees of analytic-isolating, synthetic-inflected, fused, agglutinative features)? What can be learned from sign languages? Rizzolatti and Arbib have proposed that language evolved on top of earlier mirror-neuron mechanism. Can this proposal answer the unknown questions about language and cognition? Can it explain mechanisms of language-cognition interaction? How does it relate to known brain areas and their interactions identified in brain imaging? Emotional and conceptual contents of voice sounds in animals are fused. Evolution of human language has demanded splitting of emotional and conceptual contents and mechanisms, although language prosody still carries emotional content. Is it a dying-off remnant, or is it fundamental for interaction between language and cognition? If language and cognitive mechanisms differ, unifying these two contents requires motivation, hence emotions. What are these emotions? Can they be measured? Tonal languages use pitch contours for semantic contents, are there differences in language-cognition interaction among tonal and atonal languages? Are emotional differences among cultures exclusively cultural, or also depend on languages? Interaction of language and cognition is thus full of mysteries, and we encourage papers addressing any aspect of this topic.

Download or read book Musical Prodigies written by Gary McPherson and published by Oxford University Press. This book was released on 2016 with total page 833 pages. Available in PDF, EPUB and Kindle. Book excerpt: What makes a prodigy? Although child prodigies can be found in various disciplines such as music, mathematics, chess, and art, the origins of exceptional has long been controversial. Some have dismissed the notion of innate talent, arguing that prodigies benefit from strong parental, cultural, and environmental influences that helped them develop their extraordinary abilities. Others emphasize the role of genes supported by inborn predispositions. And what role do cognitive processes, from memory to the use of imagery and language, play in such rapid and early talent development? The notion of prodigy reaches to the heart of questions about creativity, intelligence, development, and the relationship between nature and nurture. This ground-breaking book presents the first scientific exploration of musical prodigies, bringing together research from psychology, neurobiology, genetics, education, musicology, and ethnomusicology, to provide a thorough exploration of prodigious talent. With fascinating case studies of prodigies and their often complex transitions into adolescence and adulthood, this is a unique investigation of a remarkable phenomenon, for anyone interested in child development, music, and the arts. --Cover.
Download or read book Sensory Perception written by Friedrich G. Barth and published by Springer Science & Business Media. This book was released on 2012-02-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sensory perception: mind and matter aims at a deeper understanding of the many facets of sensory perception and their relations to brain function and cognition. It is an attempt to promote the interdisciplinary discourse between the neurosciences and psychology, which speaks the language of cognitive experiences, and philosophy, which has been thinking about the meaning and origin of consciousness since its beginning. Leading experts contribute to such a discourse by informing the reader about exciting modern developments, both technical and conceptual, and by pointing to the big gaps still to be bridged. The various chapters provide access to scientific research on sensory perception and the mind from a broad perspective, covering a large spectrum of topics which range from the molecular mechanisms at work in sensory cells to the study of the unconscious and to neurophilosophy.
