In people's minds, smells, flavors and affective phenomena are perceived as closely linked. But is it genuinely the case? The scientific study of this question is a rapidly expanding field, both in healthy and in clinical populations. Although still under-studied in comparison to other sensory modalities, chemical senses have proven to bring unique knowledge in the understanding of affective phenomena. In this context, this Research Topic is aimed to offer a snapshot of the present knowledge and questions raised in this field. Topics include, but are not limited to: affects elicited by odors and/or flavors in different individuals, contexts or cultures; emotional potency of odors in guiding human behavior and cognition (e.g. attention, memory formation, decisions and choices, withdrawal and approach behavior); affects communicated by body odors; affect regulation disorders and chemosensory perception. Studies on the biological underpinnings of these effects are also included.

This Element looks at the physiological and social roles of taste and the proximal chemical senses. First, how we perceive food and people when we contact them is discussed. These perceptions help us identify what we are eating and with whom we are present and serves as an analysis of the complex scene. Second, the influence of taste in food choice, metabolism, and nutrition is considered. Next, the impact of taste and the proximal chemical senses in social interactions is examined, including social eating. Then, the role of taste and the proximal chemical senses in emotion is explored.

Some investigators have argued that emotions, especially animal emotions, are illusory concepts outside the realm of scientific inquiry. However, with advances in neurobiology and neuroscience, researchers are demonstrating that this position is wrong as they move closer to a lasting understanding of the biology and psychology of emotion. In Affective Neuroscience, Jaak Panksepp provides the most up-to-date information about the brain-operating systems that organize the fundamental emotional tendencies of all mammals. Presenting complex material in a readable manner, the book offers a comprehensive summary of the fundamental neural sources of human and animal feelings, as well as a conceptual framework for studying emotional systems of the brain. Panksepp approaches emotions from the perspective of basic emotion theory but does not fail to address the complex issues raised by constructionist approaches. These issues include relations to human consciousness and the psychiatric implications of this knowledge. The book includes chapters on sleep and arousal, pleasure and fear systems, the sources of rage and anger, and the neural control of sexuality, as well as the more subtle emotions related to maternal care, social loss, and playfulness. Representing a synthetic integration of vast amounts of neurobehavioral knowledge, including relevant neuroanatomy, neurophysiology, and neurochemistry, this book will be one of the most important contributions to understanding the biology of emotions since Darwins The Expression of the Emotions in Man and Animals

The main purpose of the book is to provide insight into an area that humans often take for granted. There are wonderful and exciting stories of organisms using chemical signals as a basis of a sophisticated communication system. In many instances, chemical signals can provide more detailed and accurate information than any other mode of communication, yet this world is hidden from us because of our focus on visual and auditory signals.​ Although we have a diversity of senses available to us, humans are primarily auditory and visual animals. These stimuli are sent to the more cognitive areas of our brain where they are immediately processed for information. We use sounds to communicate and music to excite or soothe us. Our vision provides us with communication, entertainment, and information about our world. Even though our world is dominated by other stimulus energies, we have chosen, in an evolutionary sense, either auditory or visual signals to carry our most important information. This is not the case for most other organisms. Chemical signals, mediated through the sense of smell and taste, are typically more important and are used more often than other sensory signals. The world of communication using chemicals is an alien world for us. We are unaware of how important chemical signals are to other organisms and we often overlook the influence of chemical signals in our own life. Part of this naïveté about chemical signals is due to our cultural focus on visual and auditory signals, but a larger part of our collective ignorance is the lack of information about chemical communication in both popular and scientific writings. The popular press and popular writings virtually ignore the chemical senses, especially in regard to their role or influence for humans and our human culture. Academic books and textbooks are no better.

Emotion Measurement, Second Edition highlights key elements of emotions that should be considered in the measurement of emotions in both academic and commercial environments. This edition begins with an updated review of basic studies of emotion, including the theory, physiology, and psychology of emotions, as these are the foundational studies which food scientists as well as product developers and marketing professionals need to be aware of. The second section highlights methods for studying emotions, and reviews the different approaches to emotion measurement: questionnaire self-report, behavioral, and physiological. This section explores the merits of intrinsic versus extrinsic measures of emotion. Some new measurement approaches have emerged since the first edition of this book. The book then presents practical applications, with chapters on emotion research in food and beverage, as well as in a range of products and clinical settings. The experience in testing product emotions has increased since the first edition when product emotion research was newer. Finally, Emotion Measurement, Second Edition provides coverage of cross-cultural research on emotions. This is critical because much of the newer commercial research is aimed at markets around the world, requiring methods that work in many cultures. And the universality of emotions has been a topic of research for decades. Taking both an academic and applied approach, Emotion Measurement, Second Edition will be an invaluable reference for those conducting basic academic research on emotions and for sensory and consumer scientists, and the product developers and marketing professionals they work alongside. Reviews both the academic and the applied strands of emotion measurement research Focuses on cross-cultural studies of emotions, which is currently lacking from most of the literature in the field Highlights methods for studying emotions in both basic and applied studies
