This book examines a key issue in current cognitive theories - the nature of representation. Each chapter is characterized by attempts to frame hot topics in cognitive development within the landscape of current developmental theorizing and the past legacy of genetic epistemology. The chapters address four questions that are fundamental to any developmental line of inquiry:
These questions are situated in a historical context, Piagetian theory, and contemporary researchers attempt to trace how they draw upon, depart from, and transform the Piagetian legacy to revisit classic issues such as the child's awareness of the workings of mental life, the child's ability to represent the world, and the child's growing ability to process and learn from experience. The theoretical perspectives covered include constructivism, connectionism, theory-theory, information processing, dynamical systems, and social constructivist approaches. The research areas span imitation, mathematical reasoning, biological knowledge, language development, and theory of mind. Written by major contributors to the field, this work will be of interest to students and researchers wanting a brief but in-depth overview of the contemporary field of cognitive development.
This book examines a key issue in current cognitive theories - the nature of representation. Each chapter is characterized by attempts to frame hot topics in cognitive development within the landscape of current developmental theorizing and the past legacy of genetic epistemology. The chapters address four questions that are fundamental to any developmental line of inquiry: How should we represent the workings and contents of the mind? How does the child construct mental models during the course of development? What are the origins of these models? and What accounts for the novelties that are the products and producers of developmental change? These questions are situated in a historical context, Piagetian theory, and contemporary researchers attempt to trace how they draw upon, depart from, and transform the Piagetian legacy to revisit classic issues such as the child's awareness of the workings of mental life, the child's ability to represent the world, and the child's growing ability to process and learn from experience.

The 4th Workshop on Case Studies in Bayesian Statistics was held at the Car negie Mellon University campus on September 27-28, 1997. As in the past, the workshop featured both invited and contributed case studies. The former were presented and discussed in detail while the latter were presented in poster format. This volume contains the four invited case studies with the accompanying discus sion as well as nine contributed papers selected by a refereeing process. While most of the case studies in the volume come from biomedical research the reader will also find studies in environmental science and marketing research. INVITED PAPERS In Modeling Customer Survey Data, Linda A. Clark, William S. Cleveland, Lorraine Denby, and Chuanhai LiD use hierarchical modeling with time series components in for customer value analysis (CVA) data from Lucent Technologies. The data were derived from surveys of customers of the company and its competi tors, designed to assess relative performance on a spectrum of issues including product and service quality and pricing. The model provides a full description of the CVA data, with random location and scale effects for survey respondents and longitudinal company effects for each attribute. In addition to assessing the performance of specific companies, the model allows the empirical exploration of the conceptual basis of consumer value analysis. The authors place special em phasis on graphical displays for this complex, multivariate set of data and include a wealth of such plots in the paper."

From x-rays to lasers to magnetic resonance imaging, developments in basic physics research have been transformed into medical technologies for imaging, surgery and therapy at an ever-accelerating pace. Physics has joined with genetics and molecular biology to define much of what is modern in modern medicine and allied health. Covering a wide range of applications, Introduction to Physics in Modern Medicine, Third Edition builds further on the bestselling second edition. Based on the courses taught by the authors, the book provides medical personnel and students with an exploration of the physics-related applications found in state-of-the-art medical centers. Requiring no previous acquaintance with physics, biology, or chemistry and keeping mathematics to a minimum, the application-dedicated chapters adhere to simple and self-contained qualitative explanations that make use of examples, illustrations, clinical applications, sample calculations, and exercises. With an enhanced emphasis on digital imaging and computers in medicine, the text gives readers a fundamental understanding of the practical application of each concept and the basic science behind it. This book provides medical students with an excellent introduction to how physics is applied in medicine, while also providing students in physics with an introduction to medical physics. Each chapter includes worked examples and a complete list of problems and questions. That so much of the technology discussed in this book was the stuff of dreams just a few years ago, makes this book as fascinating as it is practical, both for those in medicine as well as those in physics who might one day discover that the project they are working on is the basis for the next great medical application. Features: * Introduces state-of-the-art and emerging medical technologies such as optical coherence tomography, x-ray phase contrast imaging, and ultrasound-mediated drug delivery * Covers hybrid scanners for cancer imaging and the interplay of molecular medicine with MRI, CT and PET in addition to intensity-modulated radiation therapy and new forms of cancer treatments such as proton and heavy-ion therapies * Offers an enhanced emphasis on digital imaging and dosimetry including recent innovations in the pixel-array x-ray detectors, ultrasound matrix transducers and direct-ion storage dosimeters

From the time of birth through the early school years, young children rapidly acquire two complex cognitive systems: They organize their experiences into concepts and categories, and they acquire their first language. How do children accomplish these critical tasks? How do conceptual systems influence the structure of the language we speak? How do linguistic patterns influence how we view reality? These questions have captured the interest of such theorists as Piaget, Vygotsky, Chomsky and Whorf but until recently very little has been known about the relation between language and thought during development. Perspectives on Language and Thought presents current observational and experimental research on the links between thought and language in young children. Chapters from leading figures in the field focus on the acquisition of hierarchical category systems, concepts of time, causality, and logic and the nature of language learning in both peer and adult-child social interactions.
Essentialism is the idea that certain categories, such as "dog,"
"man," or "intelligence," have an underlying reality or true nature
that gives objects their identity. Where does this idea come from?
In this book, Susan Gelman argues that essentialism is an early
cognitive bias. Young children's concepts reflect a deep commitment
to essentialism, and this commitment leads children to look beyond
the obvious in many converging ways: when learning words,
generalizing knowledge to new category members, reasoning about the
insides of things, contemplating the role of nature versus nurture,
and constructing causal explanations. Gelman argues against the
standard view of children as concrete or focused on the obvious,
instead claiming that children have an early, powerful tendency to
search for hidden, non-obvious features of things. She also attacks
claims that children build up their knowledge of the world based on
simple, associative learning strategies, arguing that children's
concepts are embedded in rich folk theories. Parents don't
explicitly teach children to essentialize; instead, during the
preschool years, children spontaneously construct concepts and
beliefs that reflect an essentialist bias.
Numerous fields stake claims about essentialism but this is the first book to address the issues surrounding essentialism from the perspective of developmental psychology. Gelman synthesizes 15 years of empirical research on essentialism into a coherent framework, examining children's thinking and ways in which language influences thought. She argues that young children's use of concepts such as "dog," "man," or "intelligence," reflects their deep commitment to the presence of these categories' properties that extends beyond the observable information about objects. The presence of this commitment in children also means that they do not come into the world as passive recipients of data, but rather have an organizational scheme that supports categories. This volume will be of interest to developmental, cognitive, and social psychologists, as well as to scholars in cognitive science and philosophy.
What is the nature of human thought? A long dominant view holds that the mind is a general problem-solving device that approaches all questions in much the same way. Chomsky's theory of language, which revolutionized linguistics, challenged this claim, contending that children are primed to acquire some skills, such as language, in a manner largely independent of their ability to solve other sorts of apparently similar mental problems. In recent years, researchers in anthropology, psychology, linguistics and neuroscience have examined whether other mental skills are similarly independent. Many have concluded that much of human thought is "domain-specific." Thus, the mind is better viewed as a collection of cognitive abilities specialized to handle specific tasks than as a general problem solver. Mapping the Mind introduces a general audience to a domain-specificity perspective, by compiling a collection of essays exploring how several of these cognitive abilities are organized. This volume is appropriate as a reader for advanced undergraduate and graduate courses in cultural psychology, psychological anthropology, developmental and cognitive psychology.

Four major themes are presented. First, children honor constraints or biases that limit the possible meanings they consider when learning new words.
