Stimulus-independent thought depends on central executive resources

Stimulus-independent thoughts (SITs) are streams of thoughts and images unrelated to immediate sensory input. Four experiments examined the contribution of aspects of working memory to production of SITs. In Experiments 1 and 2, interventions that were targeted on, respectively, phonological and visuospatial components of working memory both interfered with production of SITs, but there was evidence that these tasks also made demands on central executive resources. Experiments 3 and 4 specifically examined the hypothesis that production of SITs and control of nonproceduralized tasks both depend on central executive resources, and so should show mutual interference. In Experiment 3, prior practice on pursuit rotor and memory tasks reduced the interference with SITs from concurrent task performance. In Experiment 4, randomness within a task involving random-number generation was less when SITs were being produced concurrently than it was when they were not. The results suggest that production of SITs depends on central executive resources.     

Reflexive research and the grounding of analysis: Social psychology and the psy-complex

This paper is concerned with reflexivity in research, and the way research is grounded in the operations of the psy-complex in social psychology. A central argument is that qualitative research in general, and a focus on reflexivity in particular, requires theoretical grounding. Distinctions are drawn between ‘uncomplicated subjectivity’, ‘blank subjectivity’ and ‘complex subjectivity’; and the analytic device of the ‘discursive complex’ is described. It is argued that such theoretical grounding can usefully draw on developments in discourse analytic, deconstructionist, and psychoanalytic social research. The opposition between objectivity and subjectivity is deconstructed, and psychoanalytic conceptual reference points for an understanding of the discursive construction of complex subjectivity in the context of institutions are explored with particular reference to the location of the researcher in the psy-complex. The paper discusses the reflexive engagement of the researcher with data, and the construction of the identity of the researcher with reference to professional bodies. An analysis of a document produced by the British Psychological Society is presented to illustrate conceptual issues addressed in the first sections. This illustrative analysis is designed to show how the material is structured by a series of six discursive complexes, and that the institutional structure facilitates, and inhibits, certain forms of action and reflection.     

Factor analytic structure of theScale to Asses World View

This article reports on the factor structure of theScale to Assess World View ^(c) (SAWV). Alpha reliabilities for the factors are presented. Gender differences in world views are also explored to understand how men and women in this sample viewed the world. Recommendations for client assessment, therapy, education and training, and scale revision are discussed. The research reported here is based on a paper presented at the annual meeting of the American Psychological Association, Washington, DC, August 17, 1992.     

RESPONSE TO CRITIQUES OF ETHICS IN AN AGE OF TECHNOLOGY

Abstract. Both Roger Shinn and Robert Stivers ask whether technology has a momentum of its own that is difficult if not impossible to control (“autonomous technology” or “technological inevitability”). I reply that the difficulty in controlling technology is a product of economic and political institutions (such as corporate lobbying and campaign contributions) rather than of any inherent characteristics of technology. Against Stivers's assertion that the ecosystem should be the center of value in environmental ethics, I defend the process view that all beings are valuable, but they are not equally valuable in their richness of experience or their contribution to the experience of others. I also consider his caveats about ambiguities in the concept of sustainability. Two questions raised by Mary Gerhart are taken up: the difficulties of interdisciplinary writing and the role of theological ethics in discussions of public policy. In dialogue with Frederick Ferre I explore the role of alternative visions of the good life as a source of social change. In the face of diminished concern about social justice and environmental sustainability among citizens and in Congress since the book was written, I express long-range hope, but not optimism about the short-term prospects for change.     

What place does religion have in the ethical thinking of scientists and engineers?

Religion, defined as ‘the idea of a state that transcends ourselves and our world and the working out of the consequences of that idea’, may influence the ethical thinking of scientists and engineers in two ways. The first is at the level of the individual and how personal beliefs affect the choice of research, design or development projects, relationships with other researchers and the understandings of the consequences of research on other aspects of life. The second level is that of the social and cultural setting in which scientists and engineers work; how society decides which research to sponsor, how to apply the results of scientific discovery and which technology it chooses to develop and for what purposes. In neither of these areas is religious belief a necessary condition for scientists and engineers to pursue one course of action rather than another. The existence of religious belief within the individual and society is, though, part of the ethical framework in which scientist and engineers work and therefore something to which attention should be paid. Religion provides a particular perspective on what should be. Conversely science and technology provide information on the nature of the person and the universe in which we live, which must be taken into account when theologians and religious moralists apply their ethical norms and principles.     

An optical encoder and XY oscilloscope interface for the IBM PC

This paper outlines a prototype dual-purpose interface card for the IBM PC for use in research on motor learning and control. The card enables automatic interfacing for up to four angular optical encoders and presents high-speed visual data on an XY oscilloscope. In addition, it uses two single-chip microcontrollers with minimal external hardware, providing a more powerful instrument than is available in discrete hardware. Two microcontrollers operate independently of the experimental computer (IBM PC), using a common interface allowing the exchange of data. This interface card frees the experimental computer from the workload associated with optical encoders and high-speed XY displays, resulting in less complex experimental setups and data collection programs.
