Food for thought -- regulating energy supply to the brain during fasting
If the current financial climate has taught us anything, it's that a system where over-borrowing goes unchecked eventually ends in disaster. It turns out this rule applies as much to our bodies as it does to economics. Instead of cash, our body deals in energy borrowed from muscle and given to the brain.

Decline In Alaskan Sea Otters Affects Bald Eagles' Diet

Sea otters are known as a keystone species, filling such an important niche in ocean communities that without them, entire ecosystems can collapse. Scientists are finding, however, that sea otters can have even farther-reaching effects that extend to terrestrial communities and alter the behavior of another top predator: the bald eagle.

New Fish Species May Emerge Because Of How Females See Males

Eye color and hair color play a role in human partner choice, but visual stimuli can also determine mating preferences in the animal kingdom. In many species, the male's fortunes in the mating stakes are decided by a conspicuous breeding dress. A study of brightly colored fish has now demonstrated that this has less to do with aesthetics than with the sensitivity of female eyes, which varies as a result of adaptation to the environment.

Asian American Psychology

Current Perspectives

  • Edited by Nita Tewari, Alvin N. Alvarez

This is the first textbook written to welcome those who are new to Asian American psychology. Concepts and theories come to life by relating the material to everyday experiences and by including activities, discussion questions, exercises, clinical case studies, and internet resources. Contributions from the leading experts and emerging scholars and practitioners in the field - the majority of whom have also taught Asian American psychology - feature current perspectives and key findings from the psychological literature.

The book opens with the cornerstones of Asian American psychology, including Asian American history and research methods. Part 2 addresses how Asian Americans balance multiple worlds with topics such as racial identity, acculturation, and religion. Part 3 explores the psychological experiences of Asian Americans through the lens of gender and sexual orientation and their influence on relationships. Part 4 discusses the emerging experiences of Asian Americans, including adoptees, parachute kids, and multiracial Asian Americans. Part 5 focuses on social and life issues facing Asian Americans such as racism, academic and career development. The text concludes with an examination of the physical and psychological well-being of Asian Americans and avenues for coping and healing.

This ground-breaking volume is intended as an undergraduate/beginning graduate level introductory textbook on Asian American psychology taught in departments of psychology, Asian American and/or ethnic studies, counseling, sociology, and other social sciences. In addition, the clinical cases will also appeal to clinicians and other mental health workers committed to learning about Asian Americans.

Attitudes

Insights from the New Implicit Measures

  • Edited by Richard E. Petty, Russell H. Fazio, Pablo Brinol

This book tackles a subject that has captured the imagination of many researchers in the field: attitudes. Although the field has always recognized that people’s attitudes could be assessed in different ways, from direct self-reports to disguised observations of behavior, the past decade has shown several new approaches to attitude measurement. Despite the fact that there is no monolithic point of view with respect to implicit attitudes or measures, this book proves informative in capturing the exciting developments that have taken place over the past decade in the study of attitudes, and point the way for future exploration. Although researchers in the field have long used physiological measures, more sophisticated approaches have now been developed that rely on brain imaging techniques to examine evaluative processes. This book addresses all of these new techniques, as well as the new wave of implicit measures and the contribution they have made to understanding attitudes and attitude change.

This volume will be an essential resource for students and researchers in social psychology with an interest in the core topic of attitudes.

Perspectives on Cognitive Task Analysis

Historical Origins and Modern Communities of Practice

  • By Robert R. Hoffman, Laura G. Militello

This volume is the first comprehensive history of task analysis, charting its origins from the earliest applied psychology through to modern forms of task analysis that focus on the study of cognitive work. Through this detailed historical analysis, it is made apparent how task analysis has always been cognitive.

Chapters cover the histories, key ideas, and contributions to methodology of a number of communities of practice, including: Sociotechnics, European Work Analysis, Naturalistic Decision Making, Cognitive Systems Engineering, Ethnography, Human Factors. Further, integrative chapters focus on the purposes of cognitive task analysis.

It is shown how all the various communities of practice are living in the same scientific universe, though are in many ways distinctive in terms of their key concerns and main theories. It is a historiography of task analysis, and the people who invented task analysis. It is also an explanatory primer on what cognitive task analysis is all about and what it can do.

Perspectives on Cognitive Task Analyis will be of value to professionals in allied disciplines who might come to rely on cognitive task analysis in their system development programs. It will be invaluable to students who need to know what task analysis and cognitive task analysis are really all about. For practitioners of cognitive task analysis, this volume is a major presentation of what their scientific universe is all about.

The Development of Memory in Infancy and Childhood
  • Edited by Mary Courage, Nelson Cowan

Human memory is not only the repository of our past but the essence of who we are. As such, it is of enduring fascination. We marvel at its resilience in some situations and its fragility in others. The origin of this extraordinary cognitive capacity in infancy and childhood is the focus of vigorous research and debate as we seek to understand the record of our earliest beginnings.

The first edition of this volume, The Development of Memory in Childhood, documented the state-of-the-science of memory development a decade ago. This new edition, The Development of Memory in Infancy and Childhood, provides a thorough update and expansion of the previous text and offers reviews of new research on significant themes and ideas that have emerged since then. Topics include basic memory processes in infants and toddlers, the cognitive neuroscience of memory development, the cognitive and social factors that underlie our memory for implicit and explicit events, autobiographical memory and infantile amnesia, working memory, the role of strategies and knowledge in driving memory development, and the impact of stress and emotion on these basic processes. The book also includes applications of basic memory processes to a variety of real world settings from the courtroom to the classroom.

Including contributions from many of the best researchers in the field, this classic yet contemporary volume will appeal to senior undergraduate and graduate students of developmental and cognitive psychology as well as to developmental psychologists who want a compendium of current reviews on key topics in memory development.

Handbook of Child Language Disorders
  • Edited by Richard G. Schwartz

The Handbook of Child Language Disorders provides an in-depth, comprehensive, and state-of-the-art review of current research concerning the nature, assessment, and remediation of language disorders in children. The book includes chapters focusing on specific groups of childhood disorders (SLI, autism, genetic syndromes, dyslexia, hearing impairment); the linguistic, perceptual, genetic, neurobiological, and cognitive bases of these disorders; and the context of language disorders (bilingual, across dialects, and across languages). To examine the nature of deficits, their assessment and remediation across populations, chapters address the main components of language (morphology, syntax, semantics, and pragmatics) and related areas (processing, memory, attention, executive function such as reading and writing). Finally, even though there is extensive information regarding research and clinical methods in each chapter, there are individual chapters that focus directly on research methods.

This Handbook is a comprehensive reference source for clinicians and researchers and can be used as a textbook for undergraduate, masters, and doctoral students in speech-language pathology, developmental psychology, special education, disabilities studies, neuropsychology and in other fields interested in children's language disorders.
