In our high technology society, there is a growing demand for a better understanding of decision making in high risk situations in order to improve selection, training and operational performance. Decision Making Under Stress presents a state-of-the-art review of psychological theory, in research and practice, on decision making in high pressure and emergency situations. It focuses on the experienced decision makers who deal with such risks, principally on flight decks, at civil emergencies, in industrial settings and military environments. The 29 chapters cover a wide range of perspectives and applications from aviation, military, industry and the emergency services. The authors, all international invited experts in their field, are based in research centers and universities from Europe, North America and Australia. Their common interest is in the theories and methods of a new research domain called NDM (naturalistic decision making). This volume comprises the edited contributions to the Third International NDM conference, sponsored by the US Army Research Institute and the US Naval Air Warfare Center, which was held in Aberdeen, Scotland in September 1996. The NDM researchers are interested in decision making in situations characterised by high risk, time pressure, uncertain goals, ambiguous information and teamwork. The extent to which the NDM approach can explain and predict human performance in such settings is a central theme, discussed with many practical examples and applications. This book is essential reading for applied psychologists, pilots, emergency commanders, military officers, high hazard managers, safety and emergency response professionals.

The past fifteen years have witnessed an increasing interest in the cognitive study of the bilingual. A major reason why psychologists, psycholinguists, applied linguists, neuropsychologists, and educators have pursued this topic at an accelerating pace presumably is the acknowledgment by increasingly large numbers of language researchers that the incidence of monolingualism in individual language users may be lower than that of bilingualism. This alleged numerical imbalance between monolinguals and bilinguals may be expected to become larger due to increasing international travel through, for instance, tourism and trade, to the growing use of international communication networks, and to the fact that in some parts of the world (i.e., Europe), the borders between countries are effectively disappearing.
In addition to the growing awareness that bilinguals are very common and may even outnumber monolinguals, there is the dawning understanding that the bilingual mind is not simply the sum of the cognitive processes associated with each of the two monolingual modes, and that the two languages of bilingual may interact with one another in complicated ways. To gain a genuinely universal account of human cognition will therefore require a detailed understanding of language use by both pure monolinguals as well as bilinguals, unbalanced and balanced, and of the representations and processes involved.
These two insights, that bilingualism is a common human condition and that it may influence cognition, were presumably instrumental in putting bilingualism on the agendas of many researchers of cognition and language in recent years. But other reasons may have played a role too: The study of bilingualism also provides a unique opportunity to study the relation between language and thought. A final reason for the growing interest in this area of research is the awareness that bilingualism may confer the benefit of broadening one's scope beyond the limits of one's own country and culture.
This book serves as an excellent introduction to the important topics in the psycholinguistic study of bilingualism. The chapters represent a comprehensive and interrelated set of topics that form the core of contemporary research on the psycholinguistics of bilingualism. The issues raised within this perspective not only increase our understanding of the nature of language and thought in bilinguals but also of the basic nature of the mental architecture that supports the ability to use more than one language.

SEE SHORT BLURB FOR ALTERNATE COPY... A complex, intriguing, and important verbal entity, the proverb has been the subject of a vast number of opinions, studies, and analyses. To accommodate the assorted possible audiences, this volume outlines seven views of the proverb -- personal, formal, religious, literary, practical, cultural, and cognitive. Because the author's goal is to provide a scientific understanding of proverb comprehension and production, he draws largely on scholarship stemming from the formal, cultural, and cognitive views.
The only book about proverbs that is written from the standpoint of cognitive science, cognitive psychology, and experimentalism, this text provides a larger, more interdisciplinary perspective on the proverb. It also gives a theoretically more integrated approach to proverb cognition. The conceptual base theory of proverb comprehension is extended via the "cognitive ideals hypothesis" so that the theory now addresses issues regarding the creation, production, and pragmatics of proverbs. This hypothesis also has strong implications for a taxonomy of proverbs, proverb comprehension, universal vs. culture-specific aspects of proverbs, and some structural aspects of proverbs.
In general, the book extends the challenge of proverb cognition by using much of what cognitive science has to offer. In so doing, the proverb is compared to other forms of figurative language, which is then discussed within the larger rubric of intelligence and the inclination for using indirect modes of communication. Child developmental and brain substrates are also discussed.

Research in collective memory is a relatively new area capturing the interest of scholars in social psychology, memory, sociology, and anthropology. The core idea is that collective attitudes and behaviors are created and shared through common experiences and communication among a cohort of people. For example, people born between 1940 and 1960 are often defined via the JFK assassination and the Vietnam War. Their parents typically experienced lesser impact from these events.
Papers about collective memory have appeared in the literature under different guises for the last hundred years. Freud's "Civilization and Its Discontents, " Jung's ideas on the collective unconscious, and McDougall's speculation on the group mind posited that identity and action could be viewed as resulting from the shared development of a culture. Halbwachs, a French social psychologist (1877-1945) who was the first to write in detail about the nature of collective memory, argued that basic memory processes were all social. That is, people remember only those events that they have repeated and elaborated in their discussions with others.
In the last several years, there has been a resurgence of interest in this general topic because it addresses some fundamental questions about memory and social processes. Work closely related to these questions deals with the nature of autobiographical memory, traumatic experience and reconstructive memory, and social sharing of memories. This book brings together an international group of researchers who have been empirically studying some basic tenets of collective memory.

One of the most profound insights of the dynamic systems perspective is that new structures resulting from the developmental process do not need to be planned in advance, nor is it necessary to have these structures represented in genetic or neurological templates prior to their emergence. Rather, new structures can emerge as components of the individual and the environment self-organize; that is, as they mutually constrain each other's actions, new patterns and structures may arise. This theoretical possibility brings into developmental theory the important concept of indeterminism--the possibility that developmental outcomes may not be predictable in any simple linear causal way from their antecedents.
This is the first book to take a critical and serious look at the role of indeterminism in psychological and behavioral development.
* What is the source of this indeterminism?
* What is its role in developmental change?
* Is it merely the result of incomplete observational data or error in measurement?
It reviews the concepts of indeterminism and determinism in their historical, philosophical, and theoretical perspectives--particularly in relation to dynamic systems thinking--and applies these general ideas to systems of nonverbal communication. Stressing the indeterminacy inherent to symbols and meaning making in social systems, several chapters address the issue of indeterminism from metaphorical, modeling, and narrative perspectives. Others discuss those indeterministic processes within the individual related to emotional, social, and cognitive development.

Recently, there has been a renewal of interest in the broad and loosely bounded range of phenomena called deception and self-deception. This volume addresses this interest shared by philosophers, social and clinical psychologists, and more recently, neuroscientists and cognitive scientists. Expert contributors provide timely, reliable, and insightful coverage of the normal range of errors in perception, memory, and behavior. They place these phenomena on a continuum with various syndromes and neuropsychiatric diseases where falsehood in perception, self-perception, cognition, and behaviors are a peculiar sign. Leading authorities examine the various forms of "mythomania," deception, and self-deception ranging from the mundane to the bizarre such as imposture, confabulations, minimization of symptomatology, denial, and anosognosia. Although the many diverse phenomena discussed here share a family resemblance, they are unlikely to have a common neurological machinery. In order to reach an explanation for these phenomena, a reliable pattern of lawful behavior must be delineated. It would then be possible to develop reasonable explanations based upon the underlying neurobiological processes that give rise to deficiencies designated as the mythomanias. The chapters herein begin to provide an outline of such a development. Taken as a whole, the collection is consistent with the emerging gospel indicating that neither the machinery of "nature" nor the forces of "nurture" taken alone are capable of explaining what makes cognition and behaviors aberrant.

Psychophysical theory exists in two distinct forms -- one ascribes the explanation of phenomena and empirical laws to sensory processes. Context effects arising through the use of particular methods are an unwanted nuisance whose influence must be eliminated so that one isolates the "true" sensory scale. The other considers psychophysics only in terms of cognitive variables such as the judgment strategies induced by instructions and response biases. Sensory factors play a minor role in cognitive approaches.
This work admits the validity of both forms of theory by arguing that the same empirical phenomena should be conceptualized in two alternative, apparently contradictory, ways. This acceptance of opposites is necessary because some empirical phenomena are best explained in terms of sensory processes, while others are best ascribed to central causes.
The complementarity theory stresses the "mutually completing" nature of two distinct models. The first assigns importance to populations of sensory neurons acting in the aggregate and is formulated to deal with sensory effects. The second assigns importance to judgment uncertainty and to the subject strategies induced by experimental procedures. This model is formulated to explain context effects. Throughout the text, the exposition is interlaced with mathematics, graphs, and computer simulations designed to reveal the complementary nature of psychophysical explanations.

Metacognition is a term that spans many sub-areas in psychology and means different things to different people. A dominant view has been that metacognition involves the monitoring of performance in order to control cognition; however, it seems reasonable that much of this control runs implicitly (i.e., without awareness). Newer still is the field of implicit memory, and it has different connotations to different sub-groups as well. The editor of this volume takes it to mean that a prior experience affects behavior without the individual's appreciation (ability to report) of this influence.
Implicit memory and metacognition seem to be at two opposite ends of the spectrum -- one seemingly conscious and control-oriented, the other occurring without subjects' awareness. Do these processes relate to each other in interesting ways, or do they operate independently without reference to each other? The relatively novel conjecture that much of the control of cognition operates at an implicit level sparked Reder's desire to explore the interrelationship between the two fields.
Developed within the last two decades, both fields are very new and generate a great deal of excitement and research interest. Hundreds of articles have been written about metacognition and about implicit memory, but little if any material has been published about the two areas in combination. In other words, "Metacognition and Implicit Memory" is the first book attempting to integrate what should be closely linked efforts in the study of cognitive science.

The association between parents' behaviour and children's cognitive development is at the meeting place of several prominent theories of psychological development and a range of complex methodological and conceptual issues. On the one hand there are theories which argue that the impetus of development is within the child and is largely unaffected by his or her experience of social interaction: on the other are the commonsense experience of parents and educators, and the body of neo-Vygotskian theory, which would see the child's development as profoundly affected by social interaction or even constituted by it. The purpose of this book is to examine theories and evidence carefully in order to assess the causal links between parent behaviour and children's cognitive development.
There is a considerable amount of evidence that suggests an association between parents' behaviour and their children's cognitive development; but there are many possible explanations for this association, including direct effects of parental teaching styles on the children's learning and motivation, differential social class practices and opportunities, genetic resemblances, and methodological artifacts. A close and critical look at a wide range of research and of theory is necessary if the causal questions are to be clarified.
This book develops the current arguments about the nature and causes of cognitive development, providing a critical discussion of the available research and relating it to psychological theory. It is suitable for advanced students of psychology and education.

Panpsychism is the view that consciousness - the most puzzling and strangest phenomenon in the entire universe - is a fundamental and ubiquitous feature of the world, though in a form very remote from human consciousness. At a very basic level, the world is awake. Panpsychism seems implausible to most, and yet it has experienced a remarkable renaissance of interest over the last quarter century. The reason is the stubbornly intractable problem of consciousness. Despite immense progress in understanding the brain and its relation to states of consciousness, we still really have no idea how consciousness emerges from physical processes which are presumed to be entirely non-conscious. The Routledge Handbook of Panpsychism provides a high-level comprehensive examination and assessment of the subject - its history and contemporary development. It offers 28 chapters, appearing in print here for the first time, from the world's leading researchers on panpsychism. The chapters are divided into four sections that integrate panpsychism's relevance with important issues in philosophy of mind, philosophy of science, metaphysics, and even ethics: Historical Reflections Forms of Panpsychism Comparative Alternatives How Does Panpsychism Work? The volume will be useful to students and scholars as both an introduction and as cutting-edge philosophical engagement with the subject. For anyone interested in a philosophical approach to panpsychism, the Handbook will supply fascinating and enlightening reading. The topics covered are highly diverse, representing a spectrum of views on the nature of mind and world from various standpoints which take panpsychism seriously.

Recognizing the characteristics of children with learning disabilities and deciding how to help them is a problem faced by schools all over the world. Although some disorders are fairly easily recognizable (e.g., mental retardation) or very specific to single components of performance and quite rare (e.g., developmental dyscalculia), schools must consider much larger populations of children with learning difficulties who cannot always be readily classified. These children present high-level learning difficulties that affect their performance on a variety of school tasks, but the underlying problem is often their difficulty in understanding written text. In many instances, despite good intellectual abilities and a superficial ability to cope with written texts and to use language appropriately, some children do not seem to grasp the most important elements, or cannot find the pieces of information they are looking for. Sometimes these difficulties are not immediately detected by the teacher in the early school years. They may be hidden because the most obvious early indicators of reading progress in the teacher's eyes do not involve comprehension of written texts or because the first texts a child encounters are quite simple and reflect only the difficulty level of the oral messages (sentences, short stories, etc.) with which the child is already familiar. However, as years go by and texts get more complex, comprehension difficulties will become increasingly apparent and increasingly detrimental to effective school learning. In turn, studying, assimilating new information, and many other situations requiring text comprehension -- from problem solving to reasoning with linguistic contents -- could be affected.
Problems with decoding, dyslexia, and language disorders have attracted more interest from researchers than have specific comprehension problems and have occupied more room in specialized journals. Normal reading comprehension has also been a favorite with researchers. However, scarce interest has been paid to subjects who have comprehension difficulties. This book is an attempt to remedy this situation. In so doing, this volume answers the following questions:
* Does a reading comprehension problem exist in schools?
* How important and widespread is the problem?
* Is the problem specific?
* How can a reading comprehension difficulty be defined and identified?
* Does the "syndrome" have a single pattern or can different subtypes be identified?
* What are the main characteristics associated with a reading comprehension difficulty?
* When can other well-identified problems add to our understanding of reading comprehension difficulties?
* Which educational strategies are effective in preventing and treating reading comprehension difficulties?
* What supplementary information can we get from an international perspective?

Due to the requirements of automatic system design, and new needs for the training of complex tasks, Cognitive Task Analysis (CTA) has been used with increasing frequency in recent years by the airline industry and air traffic control community. Its power is reflected in the literature on professional training and systems design, where CTA is often cited as one of the most promising new technologies, especially for the complex cognitive tasks now confronting those working in aviation. The objective of this book is to bridge the gap between research and practice, to make what we know about CTA available to practitioners in the field. The book focuses on cognitive psychology and artificial intelligence analyses of aviation tasks. It is designed to help readers identify and solve specific design and training problems, in the flight deck, air traffic control and operations contexts. Distilling experience and guidelines from the best aviation cognitive analyses in accessible form, it is the first comprehensive volume on CTA, and is written for practitioners of cognitive analysis in aviation. It provides an overview of analyses to date; methods of data collection; and recommendations for designing and conducting CTA for use in instructional design, systems development, and evaluation. The first part of the book provides the principles and foundations of CTA, describing traditional approaches to task analysis and ways that cognitive analyses can be integrated with the analysis and development processes. The next part details how to: select the appropriate method or methods; determine job tasks that can be trained for automatic performance; extract knowledge structures; analyse mental models; and identify the decision-making and problem-solving strategies associated with experienced job performance. The authors also describe when to use and how to design and conduct a cognitive task analysis; how to use CTA along with traditional task analysis and ISD; and how to use CTA in training program development and systems design, as well as in personnel selection and evaluation. The current demand for cognitive analyses makes this a timely volume for those in aviation and, more generally, the industrial development and training communities. Readers will find this a thorough presentation of cognitive analyses in aviation and a highly usable guide in the design, implementation and interpretation of CTA. The book will be useful to instructional developers, aviation equipment and systems designers, researchers, government regulatory personnel, human resource managers, instructors, pilots, air traffic controllers, and operations staff.

The term "skill" encompasses an array of topics and issues. For example, individuals are skilled in a variety of domains such as chess, typing, air traffic control, or knitting; researchers study skill in a variety of ways, including speed of acquisition, accuracy of performance, and retention over time; and there are a variety of approaches to the study of skill such as computer modeling or experimental analysis. Contributing to the understanding of whether, how, when, and why skills may decline as a function of age is the goal of this volume.
This book is based on the Aging and Skill Conference sponsored by the Center for Applied Cognitive Research on Aging. The broad focus of the conference was to discuss cognitive theories underlying age-related skill acquisition, transfer, and retention and to discuss applications of these theories to such issues as age-adaptive training, compensatory strategies and devices, and utilization of new and existing technology. The contributors were asked to discuss the cognitive theory relevant to their topic, explain how the theory informs the field about aging, examine where gaps exist among general cognitive theory in this area and theories of aging, and demonstrate the practical relevance of the theory to enhancing or enabling activities of daily living--for work, home, or leisure--for older adults.
This is the first book to focus exclusively on aging and skill. It covers a range of abilities, provides the theoretical basis for the current status of age-related differences in skill, and offers direct evidence of the applicability of research on proficiency to aspects of daily living. Each chapter was written either by an expert in the field of aging, or by an expert in the field of skill--many expert in both areas.

Concern with stress and coping has a long history in biomedical, psychological and sociological research. The inadequacy of simplistic models linking stressful life events and adverse physical and psychological outcomes was pointed out in the early 1980s in a series of seminal papers and books. The issues and theoretical models discussed in this work shaped much of the subsequent research on this topic and are reflected in the papers in this volume. The shift has been away from identifying associations between risks and outcomes to a focus on factors and processes that contribute to diversity in response to risks. Based on the Family Research Consortium's fifth summer institute, this volume focuses on stress and adaptability in families and family members. The papers explore not only how a variety of stresses influence family functioning but also how family process moderates and mediates the contribution of individual and environmental risk and protective factors to personal adjustment. They reveal the complexity of current theoretical models, research strategies and analytic approaches to the study of risk, resiliency and vulnerability along with the central role risk, family process and adaptability play in both normal development and childhood psychopathology.

Early emotional development, emotional regulation, and the links between emotion and social or cognitive functioning in atypically developing children have not received much attention. This lack is due in part to the priorities given to the educational and therapeutic needs of these children. Yet an understanding of the basic emotional processes in children with atypical development can only serve to promote more effective strategies for teaching and intervening in the lives of these children and their families and may contribute to our understanding of basic emotional processes as well.
When referring to "emotions," the editors mean some complex set of processes or abilities, whether or not the topic is normal or atypical development. Specifically, they use the term "emotion" to refer to at least three things -- emotional expressions, emotional states, and emotional experiences. The focus of this volume, these three aspects of emotional life are affected by socialization practices, maturational change, and individual biological differences including, in this case, differences in children as a function of disability. Contributors examine the development of emotions in children with organic or psychological disorders as well as those in compromised social contexts making this volume of prime importance to developmental, clinical, and social psychologists, educators, and child mental health experts.

Signal detection theory--as developed in electrical engineering and based on statistical decision theory--was first applied to human sensory discrimination 40 years ago. The theoretical intent was to provide a valid model of the discrimination process; the methodological intent was to provide reliable measures of discrimination acuity in specific sensory tasks. An analytic method of detection theory, called the relative operating characteristic (ROC), can isolate the effect of the placement of the decision criterion, which may be variable and idiosyncratic, so that a pure measure of intrinsic discrimination acuity is obtained. For the past 20 years, ROC analysis has also been used to measure the discrimination acuity or inherent accuracy of a broad range of practical diagnostic systems. It was widely adopted by methodologists in the field of information retrieval, is increasingly used in weather forecasting, and is the generally preferred method in clinical medicine, primarily in radiology. This book attends to both themes, ROC analysis in the psychology laboratory and in practical diagnostic settings, and to their essential unity.
The focus of this book is on "detection" and "recognition" as fundamental tasks that underlie most complex behaviors. As defined here, they serve to distinguish between two alternative, confusable stimulus categories, which may be perceptual or cognitive categories in the psychology laboratory, or different states of the world in practical diagnostic tasks.
This book on signal detection theory in psychology was written by one of the developers of the theory, who co-authored with D.M. Green the classic work published in this area in 1966 (reprinted in 1974 and 1988). This volume reviews the history of the theory in engineering, statistics, and psychology, leading to the separate measurement of the two independent factors in all discrimination tasks, discrimination acuity and decision criterion. It extends the previous book to show how in several areas of psychology--in vigilance and memory--what had been thought to be discrimination effects were, in reality, effects of a changing criterion.
The book shows that data plotted in terms of the relative operating characteristic have essentially the same form across the wide range of discrimination tasks in psychology. It develops the implications of this ROC form for measures of discrimination acuity, pointing up the valid ones and identifying several common, but invalid, ones. The area under the binormal ROC is seen to be supported by the data; the popular measures "d'" and percent correct are not. An appendix describes the best, current programs for fitting ROCs and estimating their parameters, indices, and standard errors.
The application of ROC analysis to diagnostic tasks is also described. Diagnostic accuracy in a wide range of tasks can be expressed in terms of the ROC area index. Choosing the appropriate decision criterion for a given diagnostic setting--rather than considering some single criterion to be natural and fixed--has a major impact on the efficacy of a diagnostic process or system. Illustrated here by separate chapters are diagnostic systems in radiology, information retrieval, aptitude testing, survey research, and environments in which imminent dangerous conditions must be detected. Data from weather forecasting, blood testing, and polygraph lie detection are also reported. One of these chapters describes a general approach to enhancing the accuracy of diagnostic systems.

Recently, research on the ways in which goals, affect, and self-regulation influence one another has enjoyed an upsurge. New findings are being published and new theories are being developed to integrate these findings. This volume reports on the latest of this work, including a substantial amount of data and theory that has not yet been published. Emanating from a conference exploring affect as both a cause and effect in various social contexts, this book examines some of the complex and reciprocal relationships among goals, self structures, feelings, thoughts, and behavior. The chapters address:
*the effects of intrinsic versus extrinsic goals;
*the different effects of approach versus avoidance goals;
*the role of awareness in goal pursuit and affective states;
*the meaning of affective states in relation to goal attainment;
*the impact of hedonistic concerns as motivational factors;
*how people regulate their moods; and
*the role of the self in affective experiences.

The recent evolution of western societies has been characterized by an increasing emphasis on information and communication. As the amount of available information increases, however, the user -- worker, student, citizen -- faces a new problem: selecting and accessing relevant information. More than ever it is crucial to find efficient ways for users to interact with information systems in a way that prevents them from being overwhelmed or simply missing their targets. As a result, hypertext systems have been developed as a means of facilitating the interactions between readers and text. In hypertext, information is organized as a network in which nodes are text chunks (e.g., lists of items, paragraphs, pages) and links are relationships between the nodes (e.g., semantic associations, expansions, definitions, examples -- virtually any kind of relation that can be imagined between two text passages). Unfortunately, the many ways in which these hypertext interfaces can be designed has caused a complexity that extends far beyond the processing abilities of regular users. Therefore, it has become widely recognized that a more rational approach based on a thorough analysis of information users' needs, capacities, capabilities, and skills is needed. This volume seeks to meet that need.
From a user-centered perspective -- between systems and users -- this volume presents theoretical and empirical research on the cognitive processes involved in using hypertext. In so doing, it illustrates three main approaches to the design of hypertext systems:
*cognitive, which examines how users process multilayered hypertext structures;
*ergonomical, which explores how users interact with the design characteristics of hardware and software; and
*educational, which studies the learning objectives, frequency and duration of hypertext sessions, type of reading activity, and the user's learning characteristics.
This volume also tries to provide answers for the questions that have plagued hypertext research:
*What is hypertext good for?
*Who is hypertext good for?
*If it is useful for learning and instruction, then what type?
*What particular cognitive skills are needed to interact successfully with a hypertext system? Anyone interested in the fields of computer science, linguistics, psychology, education, and graphic design will find this volume intriguing, informative, and a definitive starting point for future research in the field of hypertext.

Focusing on the principles and applications of chaotic thinking, this text seeks to promote a more general understanding and acceptance of this cognitive style. It may help people deal more effectively with chaotic situations, such as economic crises, career changes, and relationship skills.
