This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health Systems, 1991] completed a gambling task [Cognition 50 (1994) 7] and the intradimensional/extradimensional (ID/ED) shift task [Nature 380 (1996) 69]. On the gambling task, psychopathic participants showed a global tendency to choose disadvantageously. Specifically, they showed an (...) impaired ability to show learning over the course of the task. On the ID/ED task, the performance of psychopathic individuals was not significantly different from incarcerated controls on attentional set-shifting, but significant impairments were found on response reversal. These results are interpreted with reference to an OFC and amygdala dysfunction explanation of psychopathy. (shrink)

The concept of brain birth has assumed a position of some significance in discussions on the status of the human embryo and on the point in embryonic development prior to which experimental procedures may be undertaken on human embryos. This paper reviews previous discussions of this concept, which have placed brain birth at various points between 12 days' and 20 weeks' gestation and which have emphasised the symmetry of brain birth and brain death. Major developmental features of brain development are (...) outlined, including the gradualness with which new features generally appear, and also the electroencephalogram (EEG) characteristics of premature infants. From this it is concluded that, if the concept of brain birth is a valid one, it should be placed at 24-28 weeks' gestation. More importantly, it is concluded that the differences between brain development and brain death throw doubt on the concept itself. (shrink)

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

The latter half of the eighteenth century saw radical changes in the way nature - both external and human nature - was perceived. It is these new perceptions, these new images of the 'the natural' that this book examines: new appreciations of the 'sublime' wildness of landscape; new revelations by the life sciences of natural creative fecundity; new assertions of the innocence of 'natural man', as illustrated by the noble savage, the contented peasant, the happy family; a new sense of (...) harmony between man and nature, reflected in changing moral, psychological, economic, and religious attitudes. Professor Charlton concentrates on French examples, for in France the contrast between old and new views was particularly vivid; but there are also numerous comparisons with England and other European countries, making this a major study in the cultural history of Europe at an especially crucial time for the formation of many of our modem assumptions about man and nature.

Revisionist interpretation of Mill needs to be extended to deal with a residue of puzzles about his moral theory and its connection with his theory of liberty. The upshot shows his reinterpretation of his Benthamite tradition as a form of ‘philosophical utilitarianism’; his definition of the art of morality as collective self-defence; his ignoring of maximization in favour of ad hoc dealing in utilities; the central role of his account of the justice of punishment; the marginal role of the internal (...) sanction in his criterion of moral wrong; his deep respect for common-sense morality; and his restriction of the scope of morality so as to claim for the utilitarian tradition the whole realm of the aesthetics of conduct as part of a general theory of practical reason.

In her valuable book Hiding from humanity: Disgust, shame and the law, Nussbaum says that she reaches many of the same practical conclusions as Mill. But she argues that Mill’s conceptions of liberty, justice, and respect for rival ideas of the good and for religious belief, are defective, and further that they do not provide as adequate a basis for the form of political liberalism she recommends. Actually, the alleged defects in Mill rest largely on misrepresentations, but more importantly, once (...) one understands the central role of Mill’s account of justice in shaping his view of liberty and morality, it becomes clear that he offers a better response to cultural pluralism. His way of relating the morality and the aesthetics of conduct embodies a kind of respect for diversity both deeper and more realistic than that claimed for political liberalism. Mill brings a heritage from the Enlightenment in the light of which political liberalism looks like a failure of nerve.

Open peer commentary on the article “A First-Person Analysis Using Third Person-Data as a Generative Method: A Case Study of Surprise in Depression” by Natalie Depraz, Maria Gyemant & Thomas Desmidt. Upshot: Supplementing physiological measures with first-person data involves several benefits and challenges. The collection and analysis of the two types of data might not be optimal within the same procedural framework. Therefore, the synthesis of the two remains problematic.

Electronic communication and commerce facilitate the collection of information about individual use of the Internet. Focusing on the case of Comet Systems Inc. and its data gathering practices, this paper explores the technical details of gathering personal information in databases in general and the special character of the privacy issue raised by 'anonymous' information about individual behavior on the Internet. The case analysis suggests new insights for our understanding of privacy and frames a discussion of policy alternatives with respect to (...) the privacy of Internet communication. (shrink)

A theory of true observation is developed as a generalization of the method of inter-observer agreement that scientists use to determine the objectivity and reliability of observations. A true observation is defined as a statement included in a set of statements in which there is statistical dependence and perfect agreement between the statements made by a universe of experimentally independent persons. Meaningfulness--the existence of an objective referent--for each form of statement included in the set is inferred from statistical dependence, correct (...) meaning within the universe of observers from the absence of disagreement. In this theory truth is inferred from a spatio-temporal pattern of statements as behavior rather than from the traditional correspondence between observation and object or logical relationships among statements.

Originally published in 1972, this book is a systematic analysis of the objectives and methods of history teaching. The book considers the criticisms of the 1960s and 70s of history as a subject and the pressures for its replacement in the school curriculum. It examines the complex psychological background of learning history and suggests that historical understanding makes an important contribution to cognitive growth. It also stresses the important part played by historical material in the emotional and imaginative life of (...) the child. Concluding with a discussion of practical classroom methods, the author proposes objectives and characteristic concepts of the subject which may be embodied in all levels of teaching. (shrink)
