This Special Issue is concerned with the effects of three emotional states (positive affect; anxiety; and depression) on performance. More specifically, the contributors focus on the potential mediating effects of attention and of executive processes of working memory. The evidence discussed suggests that anxiety and depression both impair the executive functions of shifting and inhibition, in part due to task-irrelevant processing (e.g., rumination; worry). In contrast, positive affect seems to enhance the shifting function and does not impair the inhibition function. The complicating role of motivational intensity is also discussed, as are implications for future research.

A study that goes beyond the debate over functional specialization to describe the ways that emotion and cognition interact and are integrated in the brain. The idea that a specific brain circuit constitutes the emotional brain (and its corollary, that cognition resides elsewhere) shaped thinking about emotion and the brain for many years. Recent behavioral, neuropsychological, neuroanatomy, and neuroimaging research, however, suggests that emotion interacts with cognition in the brain. In this book, Luiz Pessoa moves beyond the debate over functional specialization, describing the many ways that emotion and cognition interact and are integrated in the brain. The amygdala is often viewed as the quintessential emotional region of the brain, but Pessoa reviews findings revealing that many of its functions contribute to attention and decision making, critical components of cognitive functions. He counters the idea of a subcortical pathway to the amygdala for affective visual stimuli with an alternate framework, the multiple waves model. Citing research on reward and motivation, Pessoa also proposes the dual competition model, which explains emotional and motivational processing in terms of their influence on competition processes at both perceptual and executive function levels. He considers the broader issue of structure-function mappings, and examines anatomical features of several regions often associated with emotional processing, highlighting their connectivity properties. As new theoretical frameworks of distributed processing evolve, Pessoa concludes, a truly dynamic network view of the brain will emerge, in which "emotion" and "cognition" may be used as labels in the context of certain behaviors, but will not map cleanly into compartmentalized pieces of the brain.

Emotion can impact various aspects of our cognition and behavior, by enhancing or impairing them (e.g., enhanced attention to and memory for emotional events, or increased distraction produced by goal-irrelevant emotional information). On the other hand, emotion processing is also susceptible to cognitive influences, typically exerted in the form of cognitive control of motion, or emotion regulation. Despite important recent progress in understanding emotion- cognition interactions, a number of aspects remain unclear. The present book comprises a collection of manuscripts discussing emerging evidence regarding the mechanisms underlying emotion- cognition interactions in healthy functioning and alterations associated with clinical conditions, in which such interactions are dysfunctional. Initiated with a more restricted focus, targeting (1) identification and in depth analysis of the circumstances in which emotion enhances or impairs cognition and (2)identification of the role of individual differences in these effects, our book has emerged into a comprehensive collection of outstanding contributions investigating emotion-cognition interactions, based on approaches spanning from behavioral and lesion to pharmacological and brain imaging, and including empirical, theoretical, and review papers alike. Co-hosted by the Frontiers in Neuroscience - Integrative Neuroscience and Frontiers in Psychology - Emotion Science, the contributions comprising our book and the associated research topic are grouped around the following seven main themes, distributed across the two hosting journals: I. Emotion and Selectivity in Attention and Memory; II. The Impact of Emotional Distraction; Linking Enhancing and Impairing Effects of Emotion; III. What Really is the Role of the Amygdala?; IV. Age Differences in Emotion Processing; The Role of Emotional Valence; V. Affective Face Processing, Social Cognition, and Personality Neuroscience; VI. Stress, Mood, Emotion, and the Prefrontal Cortex; The Role of Control in the Stress Response; VII. Emotion-Cognition Interactions in Clinical Conditions. As illustrated by the present collection of contributions, emotion-cognition interactions can be identified at different levels of processing, from perception and attention to long- term memory, decision making processes, and social cognition and behavior. Notably, these effects are subject to individual differences that may affect the way we perceive, experience, and remember emotional experiences, or cope with emotionally challenging situations. Moreover, these opposing effects tend to co-occur in affective disorders, such as depression and PTSD, where uncontrolled recollection of and rumination on distressing memories also lead to impaired cognition due to emotional distraction. Understanding the nature and neural mechanisms of these effects is critical, as their exacerbation and co-occurrence in clinical conditions lead to devastating effects and debilitation. Hence, bringing together such diverse contributions has allowed not only an integrative understanding of the current extant evidence but also identification of emerging directions and concrete venues for future investigations.

Emotional Cognition gives the reader an up to date overview of the current state of emotion and cognition research that is striving for computationally explicit accounts of the relationship between these two domains. Many different areas are covered by some of the leading theorists and researchers in this area and the book crosses a range of domains, from the neurosciences through cognition and formal models to philosophy. Specific chapters consider, amongst other things, the role of emotion in decision-making, the representation and evaluation of emotive events, the relationship of affect on working memory and goal regulation. The emergence of such an integrative, computational, approach in emotion and cognition research is a unique and exciting development, one that will be of interest to established scholars as much as graduate students feeling their way in this area, and applicable to research in applied as well as purely theoretical domains.

The Wiley Handbook on the Cognitive Neuroscience of Memory presents a comprehensive overview of the latest, cutting-edge neuroscience research being done relating to the study of human memory and cognition. Features the analysis of original data using cutting edge methods in cognitive neuroscience research Presents a conceptually accessible discussion of human memory research Includes contributions from authors that represent a “who’s who” of human memory neuroscientists from the U.S. and abroad Supplemented with a variety of excellent and accessible diagrams to enhance comprehension

This authoritative handbook reviews the breadth of current knowledge about positive emotions: their nature, functions, and consequences for individuals and society. Specific emotions are analyzed in depth, including happiness, pride, romantic love, compassion, gratitude, awe, challenge, and hope. Major theoretical perspectives are presented and cutting-edge research methods explained. The volume addresses neurobiological and physiological aspects of positive emotions as well as their social and intrapersonal contexts. Implications for physical health, coping, and psychopathology are explored, as are connections to organizational functioning and consumer behavior.

Working memory--the ability to keep important information in mind while comprehending, thinking, and acting--varies considerably from person to person and changes dramatically during each person's life. Understanding such individual and developmental differences is crucial because working memory is a major contributor to general intellectual functioning. This volume offers a state-of-the-art, integrative, and comprehensive approach to understanding variation in working memory by presenting explicit, detailed comparisons of the leading theories. It incorporates views from the different research groups that operate on each side of the Atlantic, and covers working-memory research on a wide variety of populations, including healthy adults, children with and without learning difficulties, older adults, and adults and children with neurological disorders. A particular strength of this volume is that each research group explicitly addresses the same set of theoretical questions, from the perspective of both their own theoretical and experimental work and from the perspective of relevant alternative approaches. Through these questions, each research group considers their overarching theory of working memory, specifies the critical sources of working memory variation according to their theory, reflects on the compatibility of their approach with other approaches, and assesses their contribution to general working memory theory. This shared focus across chapters unifies the volume and highlights the similarities and differences among the various theories. Each chapter includes both a summary of research positions and a detailed discussion of each position. Variation in Working Memory achieves coherence across its chapters, while presenting the entire range of current theoretical and experimental approaches to variation in working memory.
