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.

The Oxford Handbook of Developmental Cognitive Neuroscience brings together the leading developmental cognitive neuroscientists in the field that work on understanding human development, and the complex interplay of genetic, environmental, and brain maturational factors that shape social and cognitive functioning in development. It includes chapters on new, emerging research areas that show promise for understanding both brain and behaviour in development, such as nutrition and the microbiome gut-brain axis and sleep. Looking beyond early developmental changes, this handbook also places importance on the period of adolescence, which is an important developmental juncture. By assuming complexity from the outset, the developmental cognitive neuroscience research approach provides much needed insights into both the initial set-up of brain networks and cognitive mechanisms, and also into adaptability across the developmental trajectory. This is important not only for scientists studying typical and atypical development, but also for interventional work looking for critical or sensitive periods where interventions would be most effective. The developmental cognitive neuroscience research approach intersects nature and nurture and considers both health and disease models. It also focuses on understanding the complexity of human development, necessitating a multi-level and multi-factor research approach to grasp change and plasticity which, by definition, is multidisciplinary. The Oxford Handbook of Developmental Cognitive Neuroscience is a landmark volume, providing the reader with a comprehensive and state-of-the-art overview of current research in the field, whilst highlighting current gaps and directions for future research.

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.

How do we sort the objects, people, events, and ideas in the world into their proper categories so that we may experience and interact with them? This fundamental question about human--and animal--perception and cognition is the subject of Categorical Perception, a comprehensive survey of a wide range of important research findings on the subject. The volume brings together all known examples of categorical perception, from research on humans and animals, infants and adults, in all the sense modalities: hearing, seeing, and touch. The perceptual findings are then interpreted in terms of the available cognitive and neuroscientific theories of how categorical perception is accomplished by the brain. Research on elementary perceptual and psychophysical categories is then compared with work on higher order categories such as objects, patterns, and abstract concepts. The book proceeds to an integrative view of categorization in general by exploring the most thoroughly investigated case of categorical perception--speech perception.

This book explores visual object recognition and introduces a collaborative model, codified as the "Perceptual Expertise Network" (PEN). It focuses on delineating the principles of high-level visual learning that can account for how different object categories are processed and associated with spatially localized activity in the primate brain. It address questions such as how expertise develops, whether there are different kinds of experts, whether some disorders such as autism or prosopagnosia can be understood as a lack or loss of expertise, and how conceptual and perceptual information interact when experts recognize and categorize objects. The research and results that have been generated by these questions are presented here, along with other questions, background information, and extant issues that have emerged from recent studies.
