Objective: To develop an approach for seeking informed consent to examine tissues retained from a previous study of sudden infant death syndrome as part of a study on asthma, and to document responses and participation rate.Design: Pilot open-ended approach to 10 volunteer SIDS parents, followed by staged approach to seek consent from the target SIDS families for the asthma study.Participants: Parents of SIDS infants known to SIDS and Kids Victoria and parents of SIDS infants from the 1991–2 SIDS in Victoria (...) case–control study.Main outcomes: Qualitative responses of the piloted parents and study parents, and participation rates.Results: The pilot group responses were used to refine the written material to be provided. Of the 72 families for which contact details were available, 45 gave verbal consent for contact by the Victorian Institute of Forensic Medicine regarding the asthma study, three refused and 24 did not respond to two letters. Thirty-three completed consent forms, all positive for participation in the asthma study, giving a positive response rate of 73% .Conclusions: The use of postmortem tissue for research is acceptable to the next of kin when an approach is sensitive to their concerns and needs and is made by experienced counsellors from a familiar organisation. Despite the painful memories evoked by the approach of the research group, the acceptance rate among those who could be contacted was high. (shrink)

Despite much research on the relationship between awareness and dementia little can be concluded concerning their relationship and the role of other factors. It is likely that studies capture different phenomena of awareness. This study aimed at identifying and delineating such variation by analysing data from three questionnaires obtained during the longitudinal study of awareness in 101 people with early-stage dementia. The data concerned awareness in relation to memory, activities of daily living and socio-emotional function. Significant differences in patterns of (...) discrepancies were obtained. This suggests that the awareness phenomena involved were structurally different; and that, in turn, this may reflect variation in the intrinsic linking between awareness and its ‘object’ . The identification of such differences is necessary so that appropriate methodologies can be applied to the study of awareness in different contexts. (shrink)

We perceive color everywhere and on everything that we encounter in daily life. Color science has progressed to the point where a great deal is known about the mechanics, evolution, and development of color vision, but less is known about the relation between color vision and psychology. However, color psychology is now a burgeoning, exciting area and this Handbook provides comprehensive coverage of emerging theory and research. Top scholars in the field provide rigorous overviews of work on color categorization, color (...) symbolism and association, color preference, reciprocal relations between color perception and psychological functioning, and variations and deficiencies in color perception. The Handbook of Color Psychology seeks to facilitate cross-fertilization among researchers, both within and across disciplines and areas of research, and is an essential resource for anyone interested in color psychology in both theoretical and applied areas of study.

In this concluding piece, we identify and discuss various aspects of convergence and, to a lesser degree, divergence in the ideas expressed in the contributions to this special section. These contributions emphatically illustrate that approach–avoidance motivation is integral to the scientific study of emotion. It is our hope that the articles herein will facilitate cross-talk among researchers and research traditions, and will lead to a more thorough understanding of the role of approach–avoidance motivation in emotion.

Robert Roth, among the first few Catholics to write favorably, even if critically, about American pragmatism, presents here a creative piece of comparative philosophy in which he achieves a long-term goal of attempting a reconciliation between pragmatism and a classical spiritual and religious perspective. The title, Radical Pragmatism, is an adaptation of William James’s "radical empiricism." James had argues that the classical empiricists, Locke and Hume, did not go far enough in their account of experience. They missed some of (...) its most important aspects, namely connections and relations, and as a result they were left with discrete sense data and sense objects. (shrink)

THERE is no trap that is easier to stumble into than that of trying to show whether one philosopher did or did not answer the problem of another philosopher. The trap consists in the tendency to think that both philosophers handled the problem in precisely the same way, even though they represent two quite different traditions. This is especially true of thinkers like David Hume and Charles Sanders Peirce. John Smith has shown quite convincingly that we cannot understand the American (...) pragmatists by limiting discussion to the epistemological questions of the British empiricist tradition stemming from Hume, Mill, and Russell. And A. J. Ayer can be faulted for attempting to do just that. However, it is possible for one to treat of Peirce's answer to Hume on necessary connection without falling into the trap. First of all, both philosophers raised the same kind of question. It is clear that Peirce had Hume specifically in mind when on many an occasion he attacked nominalism and defended real connections. But they differed in that Peirce defended his position from a broader perspective enabling him to arrive at a more satisfactory conclusion. To establish this thesis, it will be necessary to focus on several aspects of their thought that bear upon the topic under discussion. Undoubtedly the task of selection and interpretation of details has many a trap of its own, but it is hoped that the more obvious ones can be avoided. (shrink)

Compared to approach motivation, avoidance motivation evokes vigilance, attention to detail, systematic information processing, and the recruitment of cognitive resources. From a conservation of energy perspective it follows that people would be reluctant to engage in the kind of effortful cognitive processing evoked by avoidance motivation, unless the benefits of expending this energy outweigh the costs. We put forward three empirically testable propositions concerning approach and avoidance motivation, investment of energy, and the consequences of such investments. Specifically, we propose that (...) compared to approach-motivated people, avoidance-motivated people (a) carefully select situations in which they exert such cognitive effort, (b) only perform well in the absence of distracters that occupy cognitive resources, and (c) become depleted after exerting such cognitive effort.

Learning in educational settings most often emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: Perceptual learning. Here we describe research that combines principles of perceptual learning with computer technology to address persistent difficulties in mathematics learning. We report three experiments in which we developed and tested perceptual learning modules to address issues of structure extraction and fluency in relation to algebra and (...) fractions. PLMs focus students’ learning on recognizing and discriminating, or mapping key structures across different representations or transformations. Results showed significant and persisting learning gains for students using PLMs. PLM technology offers promise for addressing neglected components of learning: Pattern recognition, structural intuition, and fluency. Using PLMs as a complement to other modes of instruction may allow students to overcome chronic problems in learning. (shrink)

This paper presents a platform for developing, testing and executing synchronous collaborative applications in a distributed, heterogeneous environment. Even though several environments exist nowadays, specific problems are not treated satisfactorily. Especially in ‘real’ network environments, problems like unstable network connections and low bandwidths have to be considered.The DreamTeam platform addresses the special needs of environments with non-optimal characteristics which can, be found in distance learning scenarios. DreamTeam comprises a development environment, a simulation environment and a runtime environment; it is based (...) upon the concept of a fully decentralised architecture and encourages rapid prototyping.DreamTeam supports developers of shared applications through a component concept. Using components helps to divide a software project into well-defined parts. Well-documented interfaces help to reduce integration efforts and improve software quality. A selection of sample applications with DreamTeam validates our design concept. (shrink)

Murayama and Jach offer a thoughtful and timely critique of motivation constructs. We largely concur with their basic premises, but offer additional input and clarification regarding the importance of carefully considering the energization and direction components of motivation, and fully attending to the hierarchical aspect of motivation rather than prioritizing particular levels of analysis.
