Book excerpt: Perceptual processes mediating recognition, including the recognition of objects and spoken words, is inherently multisensory. This is true in spite of the fact that sensory inputs are segregated in early stages of neuro-sensory encoding. In face-to-face communication, for example, auditory information is processed in the cochlea, encoded in auditory sensory nerve, and processed in lower cortical areas. Eventually, these “sounds” are processed in higher cortical pathways such as the auditory cortex where it is perceived as speech. Likewise, visual information obtained from observing a talker’s articulators is encoded in lower visual pathways. Subsequently, this information undergoes processing in the visual cortex prior to the extraction of articulatory gestures in higher cortical areas associated with speech and language. As language perception unfolds, information garnered from visual articulators interacts with language processing in multiple brain regions. This occurs via visual projections to auditory, language, and multisensory brain regions. The association of auditory and visual speech signals makes the speech signal a highly “configural” percept. An important direction for the field is thus to provide ways to measure the extent to which visual speech information influences auditory processing, and likewise, assess how the unisensory components of the signal combine to form a configural/integrated percept. Numerous behavioral measures such as accuracy (e.g., percent correct, susceptibility to the “McGurk Effect”) and reaction time (RT) have been employed to assess multisensory integration ability in speech perception. On the other hand, neural based measures such as fMRI, EEG and MEG have been employed to examine the locus and or time-course of integration. The purpose of this Research Topic is to find converging behavioral and neural based assessments of audiovisual integration in speech perception. A further aim is to investigate speech recognition ability in normal hearing, hearing-impaired, and aging populations. As such, the purpose is to obtain neural measures from EEG as well as fMRI that shed light on the neural bases of multisensory processes, while connecting them to model based measures of reaction time and accuracy in the behavioral domain. In doing so, we endeavor to gain a more thorough description of the neural bases and mechanisms underlying integration in higher order processes such as speech and language recognition.

Available in PDF, EPUB and Kindle. Book excerpt: When we speak, we configure the vocal tract which shapes the visible motions of the face and the patterning of the audible speech acoustics. Similarly, we use these visible and audible behaviors to perceive speech. This book showcases a broad range of research investigating how these two types of signals are used in spoken communication, how they interact, and how they can be used to enhance the realistic synthesis and recognition of audible and visible speech. The volume begins by addressing two important questions about human audiovisual performance: how auditory and visual signals combine to access the mental lexicon and where in the brain this and related processes take place. It then turns to the production and perception of multimodal speech and how structures are coordinated within and across the two modalities. Finally, the book presents overviews and recent developments in machine-based speech recognition and synthesis of AV speech.

Available in PDF, EPUB and Kindle. Book excerpt: Speech recognition in ‘adverse conditions’ has been a familiar area of research in computer science, engineering, and hearing sciences for several decades. In contrast, most psycholinguistic theories of speech recognition are built upon evidence gathered from tasks performed by healthy listeners on carefully recorded speech, in a quiet environment, and under conditions of undivided attention. Building upon the momentum initiated by the Psycholinguistic Approaches to Speech Recognition in Adverse Conditions workshop held in Bristol, UK, in 2010, the aim of this volume is to promote a multi-disciplinary, yet unified approach to the perceptual, cognitive, and neuro-physiological mechanisms underpinning the recognition of degraded speech, variable speech, speech experienced under cognitive load, and speech experienced by theoretically relevant populations. This collection opens with a review of the literature and a formal classification of adverse conditions. The research articles then highlight those adverse conditions with the greatest potential for constraining theory, showing that some speech phenomena often believed to be immutable can be affected by noise, surface variations, or attentional set in ways that will force researchers to rethink their theory. This volume is essential for those interested in speech recognition outside laboratory constraints.

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.

This book was released on 2020-07-24 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluency is the quintessence of effective reading. To obtain socio-economic success, fluent reading is of primordial importance and reading is considered a crucial marker of an individual’s life course. Approximately 5% of children are affected by developmental dyslexia, exhibiting inaccurate word recognition, spelling, phonological decoding, and most importantly, severely dysfluent reading, which remains as their most characterizing and persistent deficit. Unable to attain society’s literacy demands, individuals with dyslexia are at severe risk for adverse academic, economic, and psychosocial consequences. Recently, it has been posed that the development of automatic letter-speech sound (LSS) integration is critical in the acquisition of fluent reading skills, and in particular that a failure to develop automatic LSS integration results in an impairment of reading fluency. In support, neurocognitive research has suggested that the development of automatized processing of LSS associations is an essential step in the formation of a functional neural network for reading. Furthermore, both neurocognitive and behavioural studies have suggested a less efficient LSS integration in children with dyslexia than in typical readers. Finally, results from intervention studies have suggested that training LSS might be a promising approach to ameliorate dysfluent reading in children with dyslexia. Nonetheless, there is still a considerable gap of knowledge in our understanding of the mechanisms by which learning LSS associations relate to (dys)fluent reading.

Available in PDF, EPUB and Kindle. Book excerpt: Cognitive neuroscience has grown into a rich and complex discipline, some 35 years after the term was coined. Given the great expanse of the field, an inclusive and authoritative resource such as this handbook is needed for examining the current state-of-the-science in cognitive neuroscience. Spread across two volumes, the 59 chapters included in this handbook systemically survey all aspects of cognitive neuroscience, spanning perception, attention, memory, language, emotion, self and social cognition, higher cognitive functions, and clinical applications. Additional chapters cover topics ranging from the use of top-down cognitive processes in visual perception to the representation and recognition of objects and spatial relations; attention and its relationship to action as well as visual motor control; language and related core abilities including semantics, speech perception and production, the distinction between linguistic competence and performance, and the capacity for written language. Special coverage is also given to chapters describing the psychopharmacology of cognition, the theory of mind, the neuroscience underlying the regulation of emotion, and neuropsychological and neuroimaging evidence that supports the special status of self-knowledge in memory. This handbook provides a comprehensive compendium of research on cognitive neuroscience that will be widely accessible to students, researchers, and professionals working in this exciting and growing field.

Available in PDF, EPUB and Kindle. Book excerpt: The major reference work for a rapidly advancing field synthesizes central themes, reports on current findings, and offers a blueprint for future research. Scientists' attempts to understand the physiology underlying our apprehension of the physical world was long dominated by a focus on the individual senses. The 1980s saw the beginning of systematic efforts to examine interactions among different sensory modalities at the level of the single neuron. And by the end of the 1990s, a recognizable and multidisciplinary field of "multisensory processes" had emerged. More recently, studies involving both human and nonhuman subjects have focused on relationships among multisensory neuronal ensembles and their behavioral, perceptual, and cognitive correlates. The New Handbook of Multisensory Processing synthesizes the central themes in this rapidly developing area, reports on current findings, and offers a blueprint for future research. The contributions, all of them written for this volume by leading experts, reflect the evolution and current state of the field. This handbook does more than simply review the field. Each of the volume's eleven sections broadly surveys a major topic, and each begins with a substantive and thought-provoking commentary by the section editor that identifies the major issues being explored, describes their treatment in the chapters that follow, and sets these findings within the context of the existing body of knowledge. Together, the commentaries and chapters provide an invaluable guide to areas of general agreement, unresolved issues, and topics that remain to be explored in this fast-moving field.

Available in PDF, EPUB and Kindle. Book excerpt: The ability to communicate through spoken and written language is one of the defining characteristics of the human race, yet it remains a deeply mysterious process. The young science of psycholinguistics attempts to uncover the mechanisms and representations underlying human language. This interdisciplinary field has seen massive developments over the past decade, with a broad expansion of the research base, and the incorporation of new experimental techniques such as brain imaging and computational modelling. The result is that real progress is being made in the understanding of the key components of language in the mind. The Oxford Handbook of Psycholinguistics brings together the views of 75 leading researchers in psycholinguistics to provide a comprehensive and authoritative review of the current state of the art in psycholinguistics. With almost 50 chapters written by experts in the field, the range and depth of coverage is unequalled. The contributors are eminent in a wide range of fields, including psychology, linguistics, human memory, cognitive neuroscience, bilingualism, genetics, development and neuropsychology. Their contributions are organised into six themed sections, covering word recognition, the mental lexicon, comprehension and discourse, language production, language development, and perspectives on psycholinguistics. The breadth of coverage, coupled with the accessibility of the short chapter format should make the handbook essential reading for both students and researchers in the fields of psychology, linguistics and neuroscience.

Available in PDF, EPUB and Kindle. Book excerpt: Synesthesia is a fascinating phenomenon which has captured the imagination of scientists and artists alike. This inherited condition gives rise to a kind of 'merging of the senses', and so for those who experience it, everyday activities like reading or listening to music trigger extraordinary impressions of colours, tastes, smells, shapes and other sensations. Synesthesia research also informs us about normal sensation because all people experience cross-sensory mappings to an implicit degree. Synesthesia has a considerably broad appeal, and in recent decades the field has experienced a resurgence of interest. These advances have painted a detailed story about the development, genetics, psychology, history, aesthetics and neuroscience of synesthesia, and provide a contemporary source of study for a new generation of scholars. The Oxford Handbook of Synesthesia brings together this broad body of knowledge into one definitive state-of-the-art handbook. It includes a large number of concisely written chapters, under broader headings, which tackle questions about the origins of synesthesia, its neurological basis, its links with language and numbers, attention and perception, and with 'normal' sensory and linguistic processing. It asks questions about synesthesia's role in language evolution, and presents both contemporary and historical overviews of the field. It shows synaesthesia's costs and benefits (e.g., in creativity, memory, imagery) and describes how synaesthesia can provide inspiration for artists and designers. The book ends with a series of perspectives on synesthesia, including a first-hand account, and philosophical viewpoints which show how synaesthesia poses unique questions about sensation, consciousness and the nature of reality.

Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with some of the association areas of the cerebral cortex and with the auditory cortex. In the first chapter, by Deepak Pandya and Edward Yeterian, the general architectural features and connections of cortical associ ation areas are considered; as these authors point out, in primates the association areas take up a considerable portion of the total cortical surface. Indeed, it is the development of the association areas that accounts for the greatest differ ences between the brains of primate and non primate species, and these areas have long been viewed as crucial in the formation of higher cognitive and be havioral functions. In the following chapter, Irving Diamond, David Fitzpatrick, and James Sprague consider the question of whether the functions of the as sociation areas depend on projections from the sensory areas of the cortex. They use the visual cortex to examine this question and show that there is a great deal of difference between species in the amount of dependence, the differences being paralleled by variations in the manner in which the geniculate and pulvinar nuclei of the thalamus project to the striate and extra striate cortical areas. One of the more interesting and perhaps least understood of the association areas is the cingulate cortex, discussed by Brent Vogt. Cingulate cortex has been linked with emotion and with affective responses to pain, and in his chapter Vogt gives an account of its cytoarchitecture, connections, and functions.
