Components of high-performance computing and communication in the behavioral sciences

By its very nature, the spectrum of computational problems approached in the behavioral sciences necessitates the use of almost all elements of high-performance computing and communication. The salient performance issues of various components—networking, disk and tape storage, memoryprocessor configurations, and processing elements—are discussed. Hardware, software, and application issues surrounding parallel computing performance are also discussed.     

Reflections …

Remarks by the symposium discussant attempt to briefly and broadly summarize the panelists’ thoughtful discussions of thePast is Prologue … for the Society for Computers in Psychology. The unique role computers have played, are playing, and will play in the behavioral sciences is reviewed. Although enthusiasm and promise for the future roles of computers as tools, as models, and as sources of study remains high, a caveat is offered.     

Automated problem solving for the behavioral sciences

In view of the obvious advantages of computers for the behavioral sciences, the question is raised as to how to make more effective use of computing capabilities. One idea is to require that fledgling behavioral scientists receive brief training in flowcharting and algorithm generation rather than a full course in computing skills. Such training would be an important adjunct for those who would go on for further instruction, especially in view of current deficiencies in many computer courses. One recurrent deficiency lies in the lack of specific guidelines for conceptualizing problems for computer implementation. Such guidelines are developed here, along with other suggestions designed to attenuate the difficulty in conceptualization.     

A model for courseware development in psychology

Many behavioral scientists are aware of the advantages of a systematic approach to research and the development of software used in research. However, coordinated and systematic efforts to develop instructional materials in the behavioral sciences are relatively rare. This paper and the symposium of which it is a part describe a systematic effort funded by FIPSE to assess the needs for microcomputer tools and courseware in the undergraduate curriculum in psychology and to stimulate the development of high-quality materials. The conceptual bases for development of materials are vertical and horizontal integration-the development of courseware that spans the curriculum from introductory to advanced, specialized, courses, and the systematic use of materials within a course and across courses and subject areas. The activities of the project, as well as implications for other computer-based development projects, are discussed.     

Integrating Behavioral and Social Sciences in the Medical School Curriculum: Opportunities and Challenges for Psychology

The Institute of Medicine has reviewed and made recommendations concerning current teaching approaches, content, and barriers to the incorporation of behavioral/social sciences in medical school curricula (Cuff & Vanselow, 2004). This paper discusses those recommendations, the history of medical education reform, the barriers to and evolution of behavioral/social sciences’ inclusion, and the implications for psychology’s future role in academic medicine. Psychological concepts and technology permeate medical practice, but little progress has been made in integrating psychological and biological sciences. Looking to its basic science domains (e.g. cognition, learning, development, neuroscience), psychology can take scientific leadership in illuminating the mechanisms by which behavioral/social processes interact with biological functions in health, thereby providing the empirical basis for a truly integrated bio-behavioral curriculum. This article is based upon a symposium, “IOM Report on Enhancing Behavioral & Social Science in Medical Education: Impact and Opportunities for Psychology,” presented at the Annual meeting of the American Psychological Association, Washington, D.C., August 21, 2005. Suzanne Bennett Johnson, Chair; Elena Reyes, John E. Carr, and Anthony Errichetti, participants; Eugene K. Emory, Discussant.     

If we compute faster, do we understand better?

Practitioners of cognitive science, “theoretical” neuroscience, and psychology have made less use of high-performance computing for testing theories than have those in many other areas of science. Why is this? In high-performance scientific computation, potentially billions of operations must lead to a trustable conclusion. Technical problems with the stability of algorithms aside, this requirement also places extremely rigorous constraints on the accuracy of the underlying theory. For example, electromagnetic interactions seem to hold accurately from atomic to galactic scales. Large-scale computations using elementary principles are possible and useful. Many have commented that the behavioral and neural sciences are largely pretheoretical. One consequence is that we cannot trust our few theories to scale well for a very good reason: They don’t. We have some quite good computational theories for single neurons and some large-scale aspects of behavior seem to be surprisingly lawful. However, we have little idea about how to go from the behavior of a single neuron to the behavior of the 10¹¹ neurons involved when the brain actually does something. Neural networks have offered one potential way to leap this enormous gap in scale, since many elementary units cooperate in a neural network computation. As currently formulated, however, neural networks seem to lack essential mechanisms that are required for flexible control of the computation, and they also neglect structure at intermediate scales of organization. We will present some speculations related to controllability and scaling in neural networks.     

Responses to critics

In response to points raised by our critics in this book symposium, we offer some clarifications about how to understand the role of science in assessing the multiple realization thesis. We also consider the connection between functionalism and multiple realization in the contexts of both psychological and biological sciences.     

Training in law and behavioral sciences: Issues from the criminal justice perspective

Interdisciplinary training in behavioral sciences and the law should be appropriate for a criminal justice education program. However, adopting such an interdisciplinary goal is problematic because the divisions in the types of educational curricula need to be confronted. The relationships of the criminal justice academic community with the profession, and of the behavioral sciences with present criminal justice policies, must also be addressed in the attempt to develop familiarity with behavioral sciences and their legal relevance in shaping the criminal justice system. These factors may hinder extensive implementation of such training. Suggestions are made for incorporating this raining in a criminal justice curriculum.     

A commentary on the symposium: The use of history in the social sciences curriculum

The use of history in the social science curriculum leads to a deepened understanding of the respective disciplines of anthropology, education, sociology, political science, psychology, and history of science. The use of history in the social sciences also leads to extradisciplinary interests in history, philosophy, and literature. Some highlights from a symposium and from the recent literature are discussed.     

“PROPAGANDISTS FOR THE BEHAVIORAL SCIENCES”: THE OVERLOOKED PARTNERSHIP BETWEEN THE CARNEGIE CORPORATION AND SSRC IN THE MID‐TWENTIETH CENTURY

The Carnegie Corporation's role as a patron of the behavioral sciences has been overlooked; its support for the behavioral sciences not only began earlier than the Ford Foundation's but was also at least equally important to their success. I show how the close postwar collaboration between the Carnegie Corporation and the Social Science Research Council (SSRC) to promote the behavioral sciences emerged after a strugglebetween Carnegie and the Rockefeller Foundation over the direction and leadership of the SSRC. I then focus on three postwar projects Carnegie helped conceive and fund that were publicized as the work of the SSRC: Chase's The Proper Study of Mankind (1948), Stouffer et al.'s The American Soldier ( 1949, 1950 ), and the Michigan's Survey Research Center 1952 election study. In each of these projects, Carnegie deliberately muted its own role and promoted the remade SSRC as a major advocate for the behavioral sciences.     

A theory of behavior interaction in dyads: A structuralist account

A theory from the behavioral and social sciences is presented from the structuralist point of view. A more comprehensive theory-net is outlined, some basic terms and core assumptions are formulated, and an expansion of the theory towards two intended applications is given. Finally, some results of a first empirical test of the theory are reported. The aim of the paper is to show that the structuralist account of scientific theories is not confined to mathematical theories from the natural sciences, but can also be applied to relatively informal constructions of the behavioral and social sciences.     

Ethical Issues in Doctoral Supervision: The Perspectives of PhD Students in the Natural and Behavioral Sciences

Our aim was to identify the ethical issues faced by students in the behavioral and natural sciences during their doctoral programmes. The participants were 28 PhD students who were interviewed about their doctoral study and supervision experiences. We identified a total of 102 ethical issues compromising the principles of nonmaleficence, beneficence, autonomy, justice, or fidelity. There were some differences in emphases, with the students in the behavioral sciences displaying a broader range of ethical compromises than the students in the natural sciences. Ethical problems emerged in the individual supervisor–student relationships, but often problems involving the scholarly community appeared in the background.     

A symposium on the use of history in the social sciences curriculum: An introduction

A symposium on the use of history in the social sciences curriculum was held at the 1980 annual meeting of the History of Science Society. It was part of a continuing series of symposia on pedagogical topics sponsored by the Committee on Undergraduate Education of the Society. Here a brief introduction is given to the three papers and the commentary presented on that occasion and published in this issue of this journal.     

psiTurk: An open-source framework for conducting replicable behavioral experiments online

Online data collection has begun to revolutionize the behavioral sciences. However, conducting carefully controlled behavioral experiments online introduces a number of new of technical and scientific challenges. The project described in this paper, psiTurk, is an open-source platform which helps researchers develop experiment designs which can be conducted over the Internet. The tool primarily interfaces with Amazon’s Mechanical Turk, a popular crowd-sourcing labor market. This paper describes the basic architecture of the system and introduces new users to the overall goals. psiTurk aims to reduce the technical hurdles for researchers developing online experiments while improving the transparency and collaborative nature of the behavioral sciences.     

The relations between neuroscience and human behavioral science.

Neuroscience seeks to understand how the human brain, perhaps the most complex electrochemical machine in the universe, works, in terms of molecules, membranes, cells and cell assemblies, development, plasticity, learning, memory, cognition, and behavior. The human behavioral sciences, in particular psychiatry and clinical psychology, deal with disorders of human behavior and mentation. The gap between neuroscience and the human behavioral sciences is still large. However, some major advances in neuroscience over the last two decades have diminished the span. This article reviews the major advances of neuroscience in six areas with relevance to the behavioral sciences: (a) evolution of the nervous system; (b) visualizing activity in the human brain; (c) plasticity of the cerebral cortex; (d) receptors, ion channels, and second/third messengers; (e) molecular genetic approaches; and (f) understanding integrative systems with networks and circadian clocks as examples.     

Bernard Berelson: Behavioral scientist

Bernard Berelson (1912–1979) was trained as a librarian and wrote two important books on reading and readers, but his major contributions to the behavioral sciences were in the fields of communications research, voting studies, and population. He virtually created the term “behavioral sciences” and he was principally responsible for the establishment of the Center for Advanced Study in the Behavioral Sciences in Stanford, California. His energy and intelligence and his belief both in the importance of behavioral empiricism and the ethical and moral dimensions of behavioral research have left an enduring legacy.     

An initial survey of fractional graph and table area in behavioral journals

This study examined the fractional graph area (FGA), the proportion of page space used to display statistical graphics, in 11 behavioral journals and places behavior analysis on a continuum with other natural, mathematical, and social science disciplines. The composite FGA of all 11 journals puts behavior analysis within the range of the social sciences, whereas the composite FGA of the most established and preeminent behavioral journals positions behavior analysis within the range of the natural sciences. In addition, fractional table area (FTA), the proportion of page space used to display tables, generally is higher in behavioral journals with lower degrees of FGA, a result that replicates previous research.     

Evolutionäre Psychiatrie

In contrast to mainstream psychiatry which mainly focuses on the proximate causes of human behavior, evolutionary psychiatry tries to elucidate the ultimate causes of the systems involved in generating specific behavioral patterns. Thus, it is in contradiction to the tabula-rasa model commonly used in social sciences. Using this explanatory approach, it is shown that behavioral sciences like human ethology initiated by K. Lorenz and I. Eibl-Eibesfeldt provide an important scientific basis for modern psychiatry.     

How are graphs read? An indication of sequence

Graphs are an extremely powerful communicative and analytical tool commonly used in both the behavioral sciences and computing (as well as many other fields). More than 2.2 trillion graphs are published annually, and these graphs are used to communicate a host of often very important information to readers. Yet despite the multitude of applications for which graphs are used, and despite the frequency of their use, little is known about how graphs communicate information or about the cognitive processes that readers use when they read and interpret the information presented within graphs. Insight into the answers to these questions can be obtained through the study of the techniques that people use to read graphs. This paper describes the research methodology and results of an empirical investigation into the viewing order in which readers choose to view the different components of graphs and into the length of time that readers spend studying each of these components.     

Relationships between the U.S. Secret Service and the behavioral and social sciences

The United States Secret Service is a federal law enforcement agency of the U.S. Department of the Treasury. The Secret Service investigates crimes related to U.S. currency, credit card fraud, forgery of government obligations, and other related violations. However, the Secret Service is perhaps best known for its protective and investigative responsibilities involving the President and Vice President of the United States, members of their immediate families, and visiting foreign dignitaries. During the past 22 years, concern for protective responsibilities has provoked occasional and sometimes fruitful dialogue between the Secret Service and members of the professional behavioral and social sciences communities. This article describes the evolution and future possibilities of that relationship by providing: (a) a brief history and overview of the Secret Service, focusing on its protective and investigative responsibilities, (b) an analysis of the recent contributions of the behavioral and social sciences to the Secret Service, and (c) an assessment of current and future directions to be taken in the professional behavioral sciences intramural and extramural research programs recently established by the Secret Service.
