This book was released on 2012-10-19 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hearing and communication present a variety of challenges to the nervous system. To be heard and understood, a communication signal must be transformed from a time-varying acoustic waveform to a perceptual representation to an even more abstract representation that integrates memory stores with semantic/referential information. Finally, this complex, abstract representation must be interpreted to form categorical decisions that guide behavior. Did I hear the stimulus? From where and whom did it come? What does it tell me? How can I use this information to plan an action? All of these issues and questions underlie auditory cognition. Since the early 1990s, there has been a re-birth of studies that test the neural correlates of auditory cognition with a unique emphasis on the use of awake, behaving animals as model. Continuing today, how and where in the brain neural correlates of auditory cognition are formed is an intensive and active area of research. Importantly, our understanding of the role that the cortex plays in hearing has the potential to impact the next generation of cochlear- and brainstem-auditory implants and consequently help those with hearing impairments. Thus, it is timely to produce a volume that brings together this exciting literature on the neural correlates of auditory cognition. This volume compliments and extends many recent SHAR volumes such as Sound Source Localization (2005) Auditory Perception of Sound Sources (2007), and Human Auditory Cortex (2010). For example, in many of these volumes, similar issues are discussed such as auditory-object identification and perception with different emphases: in Auditory Perception of Sound Sources, authors discuss the underlying psychophysics/behavior, whereas in the Human Auditory Cortex, fMRI data are presented. The unique contribution of the proposed volume is that the authors will integrate both of these factors to highlight the neural correlates of cognition/behavior. Moreover, unlike other these other volumes, the neurophysiological data will emphasize the exquisite spatial and temporal resolution of single-neuron [as opposed to more coarse fMRI or MEG data] responses in order to reveal the elegant representations and computations used by the nervous system.

Download or read book The Technology of Binaural Understanding written by Jens Blauert and published by Springer Nature. This book was released on 2020-08-12 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound, devoid of meaning, would not matter to us. It is the information sound conveys that helps the brain to understand its environment. Sound and its underlying meaning are always associated with time and space. There is no sound without spatial properties, and the brain always organizes this information within a temporal–spatial framework. This book is devoted to understanding the importance of meaning for spatial and related further aspects of hearing, including cross-modal inference. People, when exposed to acoustic stimuli, do not react directly to what they hear but rather to what they hear means to them. This semiotic maxim may not always apply, for instance, when the reactions are reflexive. But, where it does apply, it poses a major challenge to the builders of models of the auditory system. Take, for example, an auditory model that is meant to be implemented on a robotic agent for autonomous search-&-rescue actions. Or think of a system that can perform judgments on the sound quality of multimedia-reproduction systems. It becomes immediately clear that such a system needs • Cognitive capabilities, including substantial inherent knowledge • The ability to integrate information across different sensory modalities To realize these functions, the auditory system provides a pair of sensory organs, the two ears, and the means to perform adequate preprocessing of the signals provided by the ears. This is realized in the subcortical parts of the auditory system. In the title of a prior book, the term Binaural Listening is used to indicate a focus on sub-cortical functions. Psychoacoustics and auditory signal processing contribute substantially to this area. The preprocessed signals are then forwarded to the cortical parts of the auditory system where, among other things, recognition, classification, localization, scene analysis, assignment of meaning, quality assessment, and action planning take place. Also, information from different sensory modalities is integrated at this level. Between sub-cortical and cortical regions of the auditory system, numerous feedback loops exist that ultimately support the high complexity and plasticity of the auditory system. The current book concentrates on these cognitive functions. Instead of processing signals, processing symbols is now the predominant modeling task. Substantial contributions to the field draw upon the knowledge acquired by cognitive psychology. The keyword Binaural Understanding in the book title characterizes this shift. Both books, The Technology of Binaural Listening and the current one, have been stimulated and supported by AABBA, an open research group devoted to the development and application of models of binaural hearing. The current book is dedicated to technologies that help explain, facilitate, apply, and support various aspects of binaural understanding. It is organized into five parts, each containing three to six chapters in order to provide a comprehensive overview of this emerging area. Each chapter was thoroughly reviewed by at least two anonymous, external experts. The first part deals with the psychophysical and physiological effects of Forming and Interpreting Aural Objects as well as the underlying models. The fundamental concepts of reflexive and reflective auditory feedback are introduced. Mechanisms of binaural attention and attention switching are covered—as well as how auditory Gestalt rules facilitate binaural understanding. A general blackboard architecture is introduced as an example of how machines can learn to form and interpret aural objects to simulate human cognitive listening. The second part, Configuring and Understanding Aural Space, focuses on the human understanding of complex three-dimensional environments—covering the psychological and biological fundamentals of auditory space formation. This part further addresses the human mechanisms used to process information and interact in complex reverberant environments, such as concert halls and forests, and additionally examines how the auditory system can learn to understand and adapt to these environments. The third part is dedicated to Processing Cross-Modal Inference and highlights the fundamental human mechanisms used to integrate auditory cues with cues from other modalities to localize and form perceptual objects. This part also provides a general framework for understanding how complex multimodal scenes can be simulated and rendered. The fourth part, Evaluating Aural-scene Quality and Speech Understanding, focuses on the object-forming aspects of binaural listening and understanding. It addresses cognitive mechanisms involved in both the understanding of speech and the processing of nonverbal information such as Sound Quality and Quality-of- Experience. The aesthetic judgment of rooms is also discussed in this context. Models that simulate underlying human processes and performance are covered in addition to techniques for rendering virtual environments that can then be used to test these models. The fifth part deals with the Application of Cognitive Mechanisms to Audio Technology. It highlights how cognitive mechanisms can be utilized to create spatial auditory illusions using binaural and other 3D-audio technologies. Further, it covers how cognitive binaural technologies can be applied to improve human performance in auditory displays and to develop new auditory technologies for interactive robots. The book concludes with the application of cognitive binaural technologies to the next generation of hearing aids.
Download or read book Auditory Processing of Complex Sounds written by William A. Yost and published by Routledge. This book was released on 2016-07-07 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1987, this book is the result of a workshop on the processing of complex sounds held in 1986. All of the important contributions that are being made to understanding auditory processing of complex sounds could not be included in a single volume. However, the chapters do touch base with many of the lines of research and theory on complex sound and its perception at the time, and was felt that they should provide both food for thought and a broad introduction to the literature on a topic that the editors were sure would be studied intensely in the following couple of decades.
Download or read book Handbook of Learning and Cognitive Processes Volume 6 written by William Estes and published by Psychology Press. This book was released on 2014-06-20 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1978, Volume 6 concludes the survey of research and theory on learning and cognitive processes that was envisaged when the plan for this Handbook was sketched. The primary orientation in the planning the Handbook was to concentrate on research and models aimed toward the development of general cognitive theory. The first five chapters of this volume are organized in relation to one of the research areas that had expanded most vigorously during the period of planning and writing of the Handbook. These chapters treat aspects of psycholinguistics most closely related to research and theory covered in the other volumes. Perhaps the most fertile source of new concepts and models closely related to other branches of cognitive theory has been research on semantic memory. This work is given a critical review and interpretation by Smith in the first chapter of this volume, following which some lines of theoretical developmental leading "upward" into problems of comprehension of meaningful material are reviewed by Kintsch, then connections "downward" into more elementary problems of coding in memory by Johnson. Also, Johnson’s chapter shades into the very active current body of work on perceptual and memorial processes in reading, carried further by Baron’s examination of perceptual learning in relation to letter and word recognition. Finally, we consider inputs to the psycholinguistic system via speech and speech perception. The strong emphasis of Pisoni’s chapter on speech perception rather than production simply reflects both the predominance of research on perceptual aspects of speech in the current cognitive literature and the close relationships of this research to other lines of investigation of perception and short-term memory. Some knowledge of the history of the subject and some understanding of the way some of the more persuasive concepts and principles have evolved may serve present-day investigators better than boosting their reading rates. The final chapter of the present volume provides some documentation for this last suggestion.

Download or read book Impact of Auditory Training on Speech Perception and Cognitive Abilities in Older Adults with Hearing Loss written by Janel L. Cosby and published by . This book was released on 2011 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current study explored the impact of short term auditory training (LACE-Degraded) and auditory-cognitive training (LACE 4.0) on speech perceptual and cognitive measures in older adults with mild-moderate sensorineural hearing loss (SNHL). Thirty five participants, ages 60 to 80 years, with symmetrical mild-moderate SNHL completed a preliminary test battery of speech perceptual, cognitive, and self-report measures. The 35 study participants were randomly placed into one of three training groups (LACE 4.0, LACE-Degraded, or Short-Story Listening Training). Participants completed one week of training followed by post-testing. Multivariate Analysis of Variance was used to determine if significant improvements in speech perceptual, cognitive processing, and/or self-reported communication abilities occurred following the different training conditions. In addition, Pearson Product Moment correlation analyses were used to determine associations between experimental measures. No significant differences were found for initial measures of speech perceptual, cognitive processing, or self-report communication abilities; age or hearing loss between the three groups. The main finding was improvement for the LACE 4.0 group with increased performance on some speech perceptual and self-report measures. No strong correlations were found between changes in speech perception and initial measures of cognition or self-report. However, small to moderate significant correlations were found between selected speech perceptual measures, between cognitive processing measures, and between self-report measures. In the current study, tests sharing more common features tended to show significant correlations. Of interest, was a strong significant positive correlation that occurred between the Words in Noise test (speech perceptual measure) and the Time Compressed Speech test (processing speed measure). These two measures shared three out of five common task features and used words from the NU 6 word list. Unlike others studies, the current study focused on auditory and auditory-cognitive training in non-hearing aid users. These types of trainings may be a valid option for non-hearing aid users. Further confirmation of short-term training benefit is important because there is low compliance for completing the traditional longer training programs.

The cognitive science and the study of cognition and language are also considered. Psychologists will find the book invaluable.
Download or read book How and Why Does Spatial Hearing Ability Differ among Listeners What Is the Role of Learning and Multisensory Interactions written by Guillaume Andéol and published by Frontiers Media SA. This book was released on 2016-08-29 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial-hearing ability has been found to vary widely across listeners. A survey of the existing auditory-space perception literature suggests that three main types of factors may account for this variability: - physical factors, e.g., acoustical characteristics related to sound-localization cues, - perceptual factors, e.g., sensory/cognitive processing, perceptual learning, multisensory interactions, - and methodological factors, e.g., differences in stimulus presentation methods across studies. However, the extent to which these–and perhaps other, still unidentified—factors actually contribute to the observed variability in spatial hearing across individuals with normal hearing or within special populations (e.g., hearing-impaired listeners) remains largely unknown. Likewise, the role of perceptual learning and multisensory interactions in the emergence of a multimodal but unified representation of “auditory space,” is still an active topic of research. A better characterization and understanding of the determinants of inter-individual variability in spatial hearing, and of its relationship with perceptual learning and multisensory interactions, would have numerous benefits. In particular, it would enhance the design of rehabilitative devices and of human-machine interfaces involving auditory, or multimodal space perception, such as virtual auditory/multimodal displays in aeronautics, or navigational aids for the visually impaired. For this Research Topic, we have considered manuscripts that: - present new methods, or review existing methods, for the study of inter-individual differences; - present new data (or review existing) data, concerning acoustical features relevant for explaining inter-individual differences in sound-localization performance; - present new (or review existing) psychophysical or neurophysiological findings concerning spatial hearing and/or auditory perceptual learning, and/or multisensory interactions in humans (normal or impaired, young or older listeners) or other species; - discuss the influence of inter-individual differences on the design and use of assistive listening devices (rehabilitation) or human-machine interfaces involving spatial hearing or multimodal perception of space (ergonomy).
Download or read book Speech Perception By Ear and Eye written by Dominic W. Massaro and published by Psychology Press. This book was released on 2014-01-02 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1987. This book is about the processing of information. The central domain of interest is face-to-face communication in which the speaker makes available both audible and visible characteristics to the perceiver. Articulation by the speaker creates changes in atmospheric pressure for hearing and provides tongue, lip, jaw, and facial movements for seeing. These characteristics must be processed by the perceiver to recover the message conveyed by the speaker. The speaker and perceiver must share a language to make communication possible; some internal representation is necessarily functional for the perceiver to recover the message of the speak.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive collection of current research in the development of speech perception and perceptual learning documents the striking changes that take place both in early childhood and throughout life and speculates about the mechanisms responsible for those changes. The findings reported from this rich and active field address the role of growing linguistic knowledge and experience and demonstrate that speech perception develops in a bidirectional interplay with several levels of linguistic structure and cognitive processes. Examining transitions in the perceptual processing of speech from infancy to adulthood as well as what causes these transitions, the contributors take up a broad range of issues that are central to constructing a theory of speech perception and to understanding the development of this ability. These include the nature of infants' early sensory proficiencies, how these skills come to support the recognition of linguistic units, developmental differences in the representation and processing of linguistic units, the acquisition of early word patterns and a phonological system, and the mechanisms behind perceptual learning. The Development of Speech Perception is unique in attempting to integrate research involving infants, young children, and adults and in its thorough treatment of developmental issues in speech perception. It systematically explores how adult perceptual abilities begin to develop from early infant capabilities, and in doing so addresses several levels of linguistic processing.

Available in PDF, EPUB and Kindle. Book excerpt: 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."
Download or read book Neural Mechanisms of Perceptual Categorization as Precursors to Speech Perception written by Einat Liebenthal and published by Frontiers Media SA. This book was released on 2017-05-03 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perceptual categorization is fundamental to the brain’s remarkable ability to process large amounts of sensory information and efficiently recognize objects including speech. Perceptual categorization is the neural bridge between lower-level sensory and higher-level language processing. A long line of research on the physical properties of the speech signal as determined by the anatomy and physiology of the speech production apparatus has led to descriptions of the acoustic information that is used in speech recognition (e.g., stop consonants place and manner of articulation, voice onset time, aspiration). Recent research has also considered what visual cues are relevant to visual speech recognition (i.e., the visual counter-parts used in lipreading or audiovisual speech perception). Much of the theoretical work on speech perception was done in the twentieth century without the benefit of neuroimaging technologies and models of neural representation. Recent progress in understanding the functional organization of sensory and association cortices based on advances in neuroimaging presents the possibility of achieving a comprehensive and far reaching account of perception in the service of language. At the level of cell assemblies, research in animals and humans suggests that neurons in the temporal cortex are important for encoding biological categories. On the cellular level, different classes of neurons (interneurons and pyramidal neurons) have been suggested to play differential roles in the neural computations underlying auditory and visual categorization. The moment is ripe for a research topic focused on neural mechanisms mediating the emergence of speech representations (including auditory, visual and even somatosensory based forms). Important progress can be achieved by juxtaposing within the same research topic the knowledge that currently exists, the identified lacunae, and the theories that can support future investigations. This research topic provides a snapshot and platform for discussion of current understanding of neural mechanisms underlying the formation of perceptual categories and their relationship to language from a multidisciplinary and multisensory perspective. It includes contributions (reviews, original research, methodological developments) pertaining to the neural substrates, dynamics, and mechanisms underlying perceptual categorization and their interaction with neural processes governing speech perception.
