The Expression of Knowledge


Book Description

What we know about the world and its opportunities limits what we do. If we do not know that there is a pot of gold at the end of the rainbow, we will not follow it. If we do not know that a desert cactus contains water, we will not cut into it for sustenance. Often, however, we do know things about the world and yet the knowledge does not seem to be reflected in behavior. Explaining this fact simply in terms of inadequate motivation for expression or incomplete memory for the important in formation does not really add much to our understanding. The ex pression of knowledge can be interrupted in very special ways by a variety of more specific conditions-fatigue, sources of forgetting that may include failure of memory retrieval, emotion, and various dysfunc tions of brain and body systems-that are not satisfactorily incorporated by any current theories of motivation or memory. Also, a dissociation between knowledge and its expression can take the form of applying knowledge without apparent awareness of this action, a phenomenon that requires complicated assumptions for explanation in terms of either motivation or memory. Dissociations between knowledge and action may be striking. After driving home on a familiar route we may not be able to report whether the last three traffic lights were red or green; yet we must have re sponded appropriately to them.







Knowledge and Cognition


Book Description

First Published in 1974. This volume is a collection of the papers presented at the Ninth Annual Symposium on Cognition, held at Carnegie-Mellon University in May 1973. The subject of the symposium was knowledge, or rather its internal representation in human memory, or in computer systems. Of all the recent symposia in this series, this one represents a meeting of the minds, in that all of the participants were strongly oriented toward information processing theories of cognition.




Human Information Processing


Book Description

Originally published in 1974, this volume presents seven detailed views of human information processing at the time. While no single volume can do justice to the breadth of the area, it was hoped that the present selections reflected both the content and methodological approaches currently used by experimental psychologists concerned with the issues and problems of human information processing. The organization of the book is simple, proceeding from the human performance end of the continuum, an overview of which is given in the first chapter. Successive chapters are progressively more concerned with human cognition, and the last chapter gives an overview of human cognition. The intervening chapters are devoted to more specific topics and yield a detailed portrait of the models, findings, and methodology of human information processing.




Reproducibility and Replicability in Science


Book Description

One of the pathways by which the scientific community confirms the validity of a new scientific discovery is by repeating the research that produced it. When a scientific effort fails to independently confirm the computations or results of a previous study, some fear that it may be a symptom of a lack of rigor in science, while others argue that such an observed inconsistency can be an important precursor to new discovery. Concerns about reproducibility and replicability have been expressed in both scientific and popular media. As these concerns came to light, Congress requested that the National Academies of Sciences, Engineering, and Medicine conduct a study to assess the extent of issues related to reproducibility and replicability and to offer recommendations for improving rigor and transparency in scientific research. Reproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. Unlike the typical expectation of reproducibility between two computations, expectations about replicability are more nuanced, and in some cases a lack of replicability can aid the process of scientific discovery. This report provides recommendations to researchers, academic institutions, journals, and funders on steps they can take to improve reproducibility and replicability in science.

Collecting Experiments


Book Description

Databases have revolutionized nearly every aspect of our lives. Information of all sorts is being collected on a massive scale, from Google to Facebook and well beyond. But as the amount of information in databases explodes, we are forced to reassess our ideas about what knowledge is, how it is produced, to whom it belongs, and who can be credited for producing it. Every scientist working today draws on databases to produce scientific knowledge. Databases have become more common than microscopes, voltmeters, and test tubes, and the increasing amount of data has led to major changes in research practices and profound reflections on the proper professional roles of data producers, collectors, curators, and analysts. Collecting Experiments traces the development and use of data collections, especially in the experimental life sciences, from the early twentieth century to the present. It shows that the current revolution is best understood as the coming together of two older ways of knowing—collecting and experimenting, the museum and the laboratory. Ultimately, Bruno J. Strasser argues that by serving as knowledge repositories, as well as indispensable tools for producing new knowledge, these databases function as digital museums for the twenty-first century.




Cognitive Psychology and Information Processing


Book Description

First published in 1979. Basic research, at its essence, is exploration of the unknown. When it is successful, isolated pieces of reality are deciphered and described. Most of the history of an empirical discipline consists of probes into this darkness-some bold, others careful and systematic. Most of these efforts are initially incorrect. At best, they are distant approximations to a reality that may not be correctly specified for centuries. How, then, can we describe the fragmented knowledge that characterizes a scientific discipline for most of its history? A dynamic field of science is held together by its paradigm. The author’s think it is essential to adequate scientific education to teach paradigms, and believe that there is an effective method. The method emphasizes the integral nature, rather than the objective correctness, of a given set of consensual commitments. They believe that paradigmatic content can be effectively combined with the technical research literature commonly presented in scientific texts. This book represents the culmination of those beliefs.




Constructive Knowledge Acquisition


Book Description

A cognitive psychology which becomes increasingly specialized requires a special effort in order to avoid a fragmentation into several controversial issues that are independently discussed but also inherently related. Rather than asking additional differentiated questions which are then investigated by more specialized experimental methods and designs, this book promotes unified theories and a levels approach for their experimental evaluation. Within this cognitive science approach and on the basis of the most foundational assumptions of Kintsch's construction integration theory, a computational theory of knowledge acquisition is then developed and subsequently evaluated by psychological experiments. For forty years, computer simulation techniques and experimental psychology research have greatly matured the understanding of human knowledge and its acquisition in different learning environments. This volume critically assesses the advantages and limitations of these approaches and then develops an integrated research methodology. It goes on to provide significant progress concerning the following questions: * What are the most promising research methodologies for investigating human cognition? * How can the experimental psychology research on text comprehension, concept formation, and memory become more closely related to one another when the very specialized research paradigms and the highly specific scientific controversies promote their separation and independent discussion? * How can a general comprehension-based theory bridge the gap between simple experimental settings and the real-life situations that occur in education and work environments? This book demonstrates how experimental psychology can proceed more successfully by investigating those aspects that are shared among different areas of research like text comprehension, categorization, and learning by exploration. It also shows how unified theories can assist in applying experimental psychology and cognitive science results to areas such as intelligent tutoring systems, instructional design, and the development of expert systems in complex real world domains.
