Cognitive Abilities Involved in Insight Problem Solving: An Individual Differences Model

This study investigated individual differences in cognitive abilities that contribute to solving insight problems. A model is proposed describing three types of cognitive ability that contribute independently to insight: convergent thinking, divergent thinking, and breaking frame. The model was tested in a large sample (N = 108) by regressing insight problem solving performance on measures of these three abilities. This analysis demonstrated that all three abilities predicted insight independently. Convergent thinking was further broken down into verbal intelligence and working memory, which also predicted insight independently of each other and of divergent thinking and breaking frame. Finally, when pitted against noninsight problem solving as a predictor in regression, only insight problem solving was uniquely associated with divergent thinking and breaking frame. The model is suggested as a potentially useful taxonomy for the study of ill-defined problems and cognitive abilities.     

On Being Moved by Art: How Reading Fiction Transforms the Self

An experiment tested the hypothesis that art can cause significant changes in the experience of one's own personality traits under laboratory conditions. After completing a set of questionnaires, including the Big-Five Inventory (BFI) and an emotion checklist, the experimental group read the short story The Lady With the Toy Dog by Chekhov, while the control group read a comparison text that had the same content as the story, but was documentary in form. The comparison text was controlled for length, readability, complexity, and interest level. Participants then completed again the BFI and emotion checklist, randomly placed within a larger set of questionnaires. The results show the experimental group experienced significantly greater change in self-reported experience of personality traits than the control group, and that emotion change mediated the effect of art on traits. Further consideration should be given to the role of art in the facilitation of processes of personality growth and maturation.     

Responsible Conduct of Research Training and Trust Between Research Postgraduate Students and Supervisors

The federal regulations of human research were written to permit the use of discretion so that research can fit the circumstances under which it is conducted. For example, the researcher and institutional review board (IRB) could waive or alter some informed consent elements if they deem this the morally and scientifically best way to conduct the research. To do so, however, researchers and IRBs would first have to use mature moral and scientific judgment. They might also have to rely on empirical research to discover the most effective way to act on their moral sense (e.g., to discover how best to approach potential research participants and explain the nature and purpose of the research participation for which they are being recruited, to ensure comprehension and competent decision making). On discovering the most ethical way to proceed, they would then need to look to the federal regulations of human research to discover how to document their decision and justify it within that somewhat flexible regulatory structure. Unfortunately, many IRBs and researchers fail to take these sensible steps to solve ethical problems and proceed immediately to a default requirement of the regulations that places science at odds with the regulations and, ostensibly, with ethics. The following articles in this special issue are about the process of learning to engage in ethical problem solving and using the flexibility permitted by the federal regulations. These articles extricate researchers from the mindset that has gotten them into trouble, and, ideally, provoke them to use mature common sense and moral judgment.     

Projective Drawings in a Cerebellar Disorder Due to Chicken Pox Encephalitis

Projective drawings may be more sensitive to cerebellar disorders than the Rorschach or the geometric designs of the Bender. Drawings of a nine-year-old whose “bad case of chicken pox” was later diagnosed as varicella encephalitis are presented, with suggestions as to why this sensitivity may occur.     

Carnapian explications,experimental philosophy,and fruitful concepts

It seems natural to think that Carnapian explication and experimental philosophy can go hand in hand. But what exactly explicators can gain from the data provided by experimental philosophers remains controversial. According to an influential proposal by Shepherd and Justus, explicators should use experimental data in the process of ‘explication preparation’. Against this proposal, Mark Pinder has recently suggested that experimental data can directly assist an explicator’s search for fruitful replacements of the explicandum. In developing his argument, he also proposes a novel aspect of what makes a concept fruitful, namely, that it is taken up by the relevant community. In this paper, I defend explication preparation against Pinder’s objections and argue that his uptake proposal conflates theoretical and practical success conditions of explications. Furthermore, I argue that Pinder’s suggested experimental procedure needs substantial revision. I end by distinguishing two kinds of explication projects, and showing how experimental philosophy can contribute to each of them.     

The Cascade Neural Network Model and a Speed-Accuracy Trade-Off of Arm Movement

We propose a hybrid neural network model of aimed arm movements that consists of a feedforward controller and a postural controller. The cascade neural network of Kawato, Maeda, Uno, and Suzuki (1990) was employed as a computational implementation of the feedforward controller. This network computes feedforward motor commands based on a minimum torque-change criterion. If the weighting parameter of the smoothness criterion is fixed and the number of relaxation iterations is rather small, the cascade model cannot calculate the exact torque, and the hand does not reach the desired target by using the feedforward control alone. Thus, one observes an error between the final position and the desired target location. By using a fixed weighting parameter value and a limited iteration number to simulate target-directed arm movements, we found that the cascade model generated a planning time–accuracy trade-off, and a quasi–power-law type of speed–accuracy trade-off. The model provides a candidate neural mechanism to explain the stochastic variability of the time course of the feedforward motor command. Our approach also accounts for several invariant features of multijoint arm trajectories, such as roughly straight hand paths and bell-shaped speed profiles.     

Thick Ethical Concepts in the Philosophy and Literature of Iris Murdoch

Although thick ethical concepts have been neglected in Murdochian scholarship, this article argues that they were central to the thought of Iris Murdoch. In the first section, the article provides a sustained account of thick ethical concepts in Murdoch's philosophy, demonstrating how these concepts align with and illuminate familiar aspects of her philosophical essays. The first section also explores the ways in which Murdoch's alternative account of moral concepts was at the heart of her overall attack on the noncognitivism of her day. In the second section, the article provides a reading of The Black Prince and considers the ways that thick ethical concepts offer new insight into Murdoch's literary activity. It concludes by suggesting that studying Murdoch's philosophy and literature in light of thick ethical concepts reveals a deep unity between her two intellectual projects.     

ideology and the stagnation of aoda treatment modalities in america

The disease model of alcoholism was adopted by the American Medical Assoication in 1956, and the intervening 47 years have seen the development of increasingly varied and sophisticated types of evidence for the biological sources of addiction to Alcohol and other drugs of abuse (AODA) . However, a synthesis of 12-step treatment with a confrontational and moralistic version of cognitive psychology remains the modal approach to AODA treatment, despite its inability to even engage many addicts. Simultaneously, the growing evidence for therapies that teach self-regulation of biopsychological processes, which treat clients supportively while encouraging their recognition of the problems and building their desire to change, has been largely ignored by practitioners. The epitome of this self-regulation approach, neurofeedback therapy, has been all but ignored despite reports of high success rates. This paper examines the confluence historical economic and ideological factors that maintain this divergence between knowledge and practice from the perspective of Gusfield's notion of moral passage based on deviant labels.
