Advancing Creativity Theory and Research: A Socio-cultural Manifesto

This manifesto, discussed by 20 scholars, representing diverse lines of creativity research, marks a conceptual shift within the field. Socio-cultural approaches have made substantial contributions to the concept of creativity over recent decades and today can provide a set of propositions to guide our understanding of past research and to generate new directions of inquiry and practice. These propositions are urgently needed in response to the transition from the Information Society to the Post-Information Society. Through the propositions outlined here, we aim to build common ground and invite the community of creativity researchers and practitioners to reflect up, study, and cultivate creativity as a socio-cultural phenomenon.     

Samuel Scheffler on Valuing and Considering Valuable

Philosophia - Consider the utterances ‘our friendship is valuable’ and ‘I value our friendship’. On the face of it, these aren’t semantic equivalents: the former...     

Guilt and Shame,Justice and Mercy

This essay argues that the criminal justice system in the United States is flawed because it focuses principally on punishment of illegal actions without considering offenders as persons in their entirety. It considers the role that constructive shame and mercy can play in addressing this flaw. The essay concludes by applying this argument to the case of shaming penalties within criminal justice.     

Critique of an epistemic account of fallacies

An epistemic account of fallacies is one which takes it as a necessary condition for a fallacy that it has a tendency to produce false or unwarranted beliefs. The most sophisticated form of this account occurs in an article by Robert J. Fogelin and Timothy J. Duggan (Fallacies,Argumentation 1, 1987, pp. 255–262). I criticize the Fogelin and Duggan proposal, in particular, and epistemic accounts, more generally. Though an epistemic approach is attractive, it enlarges the class of fallacies, beyond what would be permitted by traditional accounts. I also question thenecessity of fallacies leading to unwarranted beliefs. Some fallacies are fallacious due to their expected harm to argument practices. This position touches on a theme in the work of Van Eemeren and Grootendorst, though I criticize their notion of rules of argument as too broad.     

Repression and effective coping styles

This study investigated the relationship between repressive coping style as defined by Weinberger (1990)—low reported anxiety and high reported defensiveness—and several individual difference measures related to general coping styles. Twenty‐nine studies looking at cognitive, behavioural, and individual difference factors associated with repressive coping were tabulated and reviewed. In the current study 116 women and 32 men were administered a questionnaire including measures of personality, ways of coping, self‐monitoring, interpersonal influence, and locus of control to further explore the repressor coping style. Two measures, as opposed to the usual one, were used to categorize repressors: the use of anxiety and social desirability measures of Weinberger, Schwartz and Davidson (1979) and the Gudjonsson (1981) method using Neuroticism and Lie scales from the EPQ(R). Analysis of variance showed that repressors reported using more positive/healthy and less negative/unhealthy coping styles. The results did not change substantially when more extreme scoring groups were used. Factor analysis of the scales revealed six clear factors relating to ways of coping; again, repressors scored highly on the factor denoting positive coping. It was also found that the Lie and Neuroticism scales of the revised EPQ personality questionnaire of Eysenck, Eysenck and Barrett (1985) could be used as a substitute for anxiety and defensiveness to predict repression with considerable success. However results from both one‐ and two‐way analysis of variance indicated that the two different ways of classifying repressors was not totally inter‐changeable as the overlap in results occurred only with highly significant effects. The results are discussed in the light of previous investigations into repression which suggested that repressors report an overly optimistic way of coping in order to avoid negative affect.

Functional magnetic resonance imaging: Overview and methods for psychological research

Functional magnetic resonance imaging (fMRI) allows noninvasive imaging of hemodynamic changes related to neural activity. This technique can be used in single-subject designs and can provide millimeter spatial resolution and temporal resolution in the range of 5–10 sec. This paper provides a brief introduction to MRI techniques and their application to functional neuroimaging, focusing on methodological issues that are of particular concern to psychologists, including methods for presenting computerized stimuli to subjects without disrupting the scanner, experimental design issues, and statistical analysis and image processing procedures. To illustrate methodological issues, recent results from a series of studies looking at the topographic organization of visual cortex are presented. General issues concerning limitations in this technique, future directions in its development, its relationship to other neuroimaging techniques, and the role of functional neuroimaging in psychological research are addressed in the Discussion.     

Distributed and massed practice: from laboratory to classroom

The benefit to memory of spacing presentations of material is well established but lacks an adequate explanation and is rarely applied in education. This paper presents three experiments that examined the spacing effect and its application to education. Experiment 1 demonstrated that spacing repeated presentations of items is equally beneficial to memory for a wide range of ages, contrary to some theories. Experiment 2 introduced ‘clustered’ presentations as a more relevant control than massed, reflecting the fact that massed presentation of material is uncommon in education. The scheduling of clustered presentations was intermediate between massed and distributed, yet recall was no different than for massed. Experiment 3, a classroom‐based study, demonstrated the benefit of distributed over clustered teaching of reading through modification of the scheduling of everyday lessons. Thus, the effectiveness of teaching may be improved by increasing the degree to which lessons are distributed. Copyright © 2004 John Wiley & Sons, Ltd.     

Normalization and excluded middle. I

The usual rule used to obtain natural deduction formulations of classical logic from intuitionistic logic, namely is stronger then necessary, and will give classical logic when added to minimal logic. A rule which is precisely strong enough to give classical logic from intuitionistic logic, and which is thus exactly equivalent to the law of the excluded middle, is It is a special case of a version of Peirce's law: In this paper it is shown how to normalize logics defined using these last two rules. Part I deals with propositional logics and first order predicate logics. Part II will deal with first order arithmetic and second order logics.

Public health concerns take center stage in Nuffield Council on Bioethics

Summary Nonhuman primates represent an important reservoir for the transmission of new infectious diseases to humans. While several working groups and international agencies have grappled with the ethics of xenotransplantation, the Nuffield Council on Bioethics have recently published a comprehensive and far-reaching series of recommendations that, while not eliminating the infectious disease risks, have nonetheless detailed the major points for concern and have developed a rational approach to minimizing these risks. This report should serve as the blueprint from which to proceed with xenotransplantation. Dr. Allan’s research focuses on simian retroviruses, including simian immunodeficiency viruses (SIV).
