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.

Foreword by Richard J. Stevenson, Macquarie University (Australia). It was long thought that the human nose might be able to discriminate somewhere in the order of 10,000 different odourants. The recent finding that the human nose can discriminate something like a trillion different smells serves as yet another reminder that we have again underestimated the capacity of our sense of smell (Bushdid, Magnasco, Vosshall & Keller, 2014). This volume serves as a further corrective for anyone who should hold the view that olfaction is unimportant in human affairs. The papers presented in this ebook, carefully collated and overseen by Aldo Zucco, Benoist Schaal, Mats Olsson and Ilona Croy, showcase a large number of quite different reasons for studying the applied side of olfaction, and indeed human olfaction in general. The 23 contributions presented here cover a broad range of topics, which illustrate contemporary interests in our field. Although with a strong applied focus, a noteworthy feature of this ebook is the richness of the theoretical perspectives that are developed. These range from considerations of olfactory perception, memory, expertise, and priming right the way through to receptor genetics. These contributions, from many leading experts in the field, will surely shape much of the applied work linking olfaction to disease, which is a further focus of this ebook. In respect to health and disease, the chapters on aging, pregnancy, depression, alcohol dependency and environmental odours, present overviews and rich new data on many contemporary problems, to which the study of olfaction is now contributing. A particularly notable aspect of olfactory experience is the affective impact that odours can have on people and their lives. The ebook covers some particularly intriguing aspects of work in this area, with empirical studies investigating dissociations between wanting and liking, stress reduction in the elderly, mother-infant bonding, and the emotions that different odourants can evoke. This affective line of work is nicely complemented by empirical studies on expertise, the effect of odours on visual attention, and the relationship between particular personality traits and interest in olfaction. The gradual appropriation of methods from cognitive neuroscience into olfaction is also nicely represented in this ebook, with at least three of the chapters reporting data using neuroimaging, including a particular intriguing study looking at recognition of odours in mixtures. Finally, the close links between olfactory perception and sensory evaluation are also reflected in a chapter on wine. I hope that readers of this e-book will be struck, as I have been in reading its various chapters, how much olfaction affects our lives, and how the study of this sense can enrich it.

The human body has developed complex sensory processing systems which manifest themselves in our emotions, memory, and language. This book examines such olfactory and gustatory cognition. Leading experts have written chapters on many facets of taste and smell, including odor memory, genetic variation in taste, and the hedonistic dimensions of odors.

Olfactory dysfunction, also known as anosmia and hyposmia, is one of the most prevalent (80-90%) symptoms reported by patients with COVID-19. Outside the context of COVID-19, chemosensory dysfunction has been associated with decreased quality of life, anxiety, depression, and cognitive impairment. In the setting of COVID-19, decreased sense of smell has been positively associated with mood disorders such as anxiety and depression. The short-term and long-term neuropsychiatric implications of the olfactory dysfunction related to COVID-19 are still largely unexplored. Investigation of the neuropsychiatric sequelae of olfactory dysfunction related to COVID-19 infection is particularly critical to characterize the pathological effects of COVID-19 on brain function and to develop strategies to improve patient’s quality of life and mental wellbeing. In this Research Topic, Frontiers aims to highlight studies that investigate the neuropsychiatric, psychological, and cognitive consequences of COVID-19-related olfactory dysfunction, present current advances in the field, and anticipate health care needs for the development of therapeutic interventions.

This book highlights the state of the field in the new, provocative line of research into the cognition and behavior of the domestic dog. Eleven chapters from leading researchers describe innovative methods from comparative psychology, ethology and behavioral biology, which are combined to create a more comprehensive picture of the behavior of Canis familiaris than ever before. Each of the book’s three parts highlights one of the perspectives relevant to providing a full understanding of the dog. Part I covers the perceptual abilities of dogs and the effect of interbreeding. Part II includes observational and experimental results from studies of social cognition – such as learning and social referencing – and physical cognition in canids, while Part III summarizes the work in the field to date, reviewing various conceptual and methodological approaches and testing anthropomorphisms with regard to dogs. The final chapter discusses the practical application of behavioral and cognitive results to promote animal welfare. This volume reflects a modern shift in science toward considering and studying domestic dogs for their own sake, not only insofar as they reflect back on human beings.

This book unites cutting-edge research related to various aspects of dog olfaction. It includes rich expertise about detection dogs with application perspectives, and expands beyond. In four clearly arranged sections, readers will discover specialist contributions on: the fundamentals of olfaction, anatomy, comparative olfactory neuroscience and dysfunction methodological reflections on canine olfactometry and essential implications for practice, comprising dog selection for scent detection, handler bias and signal detection concepts the connection with dog behavior, cognition, welfare, and learning and training methods diverse application examples of dog olfactory capabilities, such as disease detection for diagnostics, infectious disease surveillance, forensics and ecological conservation The unique and exciting link between science and practice makes this book a valuable read not only for researchers, but also for practicing veterinarians and professionals in the fields of canine detection, chemical sensing, working dog behavior and welfare.

This new book includes within its scope original research on basic processes of cognition, learning, memory, imagery, concept formation, problem-solving, decision-making, thinking, reading, and language processing.

Approximately 380 million people worldwide are 60 years of age or older. This number is predicted to triple to more than 1 billion by 2025. Aging, Nutrition and Taste: Nutrition, Food Science and Culinary Perspectives for Aging Tastefully provides research, facts, theories, practical advice and recipes with full color photographs to feed the rapidly growing aging population healthfully. This book takes an integrated approach, utilizing nutrition, food science and the culinary arts. A significant number of aging adults may have taste and smell or chemosensory disorders and many may also be considered to be undernourished. While this can be partially attributed to the behavioral, physical and social changes that come with aging, the loss or decline in taste and smell may be at the root of other disorders. Aging adults may not know that these disorders exist nor what can be done to compensate. This text seeks to fill the knowledge gap. Aging, Nutrition and Taste: Nutrition, Food Science and Culinary Perspectives for Aging Tastefully examines aging from three perspectives: nutritional changes that affect health and well-being; food science applications that address age-specific chemosensory changes, compromised disease states and health, and culinary arts techniques that help make food more appealing to diminishing senses. Beyond scientific theory, readers will find practical tips and techniques, products, recipes, and menus to increase the desirability, consumption and gratification of healthy foods and beverages as people age. - Presents information on new research and theories including a fresh look at calcium, cholesterol, fibers, omega-3 fatty acids, higher protein requirements, vitamins C, E, D, trace minerals and phytonutrients and others specifically for the aging population - Includes easy to access and usable definitions in each chapter, guidelines, recommendations, tables and usable bytes of information for health professionals, those who work with aging populations and aging people themselves - Synthesizes overall insights in overviews, introductions and digest summaries of each chapter, identifying relevant material from other chapters and clarifying their pertinence

This volume presents novel cross-linguistic insights into how olfactory experiences are expressed in typologically (un-)related languages both from a synchronic and from a diachronic perspective. It contains a general introduction to the topic and fourteen chapters based on philological investigation and thorough fieldwork data from Basque, Beja, Fon, Formosan languages, Hebrew, Indo-European languages, Japanese, Kartvelian languages, Purepecha, and languages of northern Vanuatu. Topics discussed in the individual chapters involve, inter alia, lexical olfactory repertoires and naming strategies, non-literal meanings of olfactory expressions and their semantic change, reduplication, colexification, mimetics, and language contact. The findings provide the reader with a range of fascinating facts about perception description, contribute to a deeper understanding of how olfaction as an understudied sense is encoded linguistically, and offer new theoretical perspectives on how some parts of our cognitive system are verbalized cross-culturally. This volume is highly relevant to lexical typologists, historical linguists, grammarians, and anthropologists.

This volume presents the latest research in the broad field of the chemical senses from the International Symposium on Olfaction and Taste. This field includes not only the obvious senses of taste and smell but also chemical irritation and related sensations. Scientists investigate the mechanisms and functions of the chemical senses in the oral and nasal cavity as well as in the viscera including the gut and airways. This volume takes an integrative approach and provides historical context for modern research in the field. NOTE: Annals volumes are available for sale as individual books or as a journal.
