By examining the shared neuro-cognitive correlates of curiosity and creativity, we better understand the brain basis of creativity. However, by only examining shared components, important neuro-cognitive correlates are overlooked. Here, we argue that any comprehensive brain model of creativity should consider multiple cognitive processes and, alongside the interplay between brain networks, also the neurochemistry and neural oscillations that underly creativity.

We investigate how the perceived uncertainty of a conditional affects a person's choice of conclusion. We use a novel procedure to introduce uncertainty by manipulating the conditional probability of the consequent given the antecedent. In Experiment 1, we show first that subjects reduce their choice of valid conclusions when a conditional is followed by an additional premise that makes the major premise uncertain. In this we replicate Byrne. These subjects choose, instead, a qualified conclusion expressing uncertainty. If subjects are given (...) a third statement that qualifies the likelihood of the additional premise, then the uncertainty of the conclusions they choose is systematically related to the suggested uncertainty. Experiment 2 confirms these observations in problems that omit the additional premise and qualify the first premise directly. Experiment 3 shows that the qualifying statement also affects the perceived probability of the consequent given the antecedent of the conditional. Experiment 4 investigates the effect of suggested uncertainty on the fallacies and shows that increases in uncertainty reduce the number of certain conclusions that are chosen while affirming the consequent but have no effect on denying the antecedent. We discuss our results in terms of rule theories and mental models and conclude that the latter give the most natural account of our results. (shrink)

Four experiments investigated uncertainty about a premise in a deductive argument as a function of the expertise of the speaker and of the conversational context. The procedure mimicked everyday reasoning in that participants were not told that the premises were to be treated as certain. The results showed that the perceived likelihood of a conclusion was greater when the major or the minor premise was uttered by an expert rather than a novice (Experiment 1). The results also showed that uncertainty (...) about the conclusion was higher when the major premise was uttered by a novice and an alternative premise by an expert, compared to when the major premise was uttered by an expert and the alternative by a novice (Experiment 2). Similarly, the believability of a conclusion was considerably lower when the minor premise was uttered by a novice and denied by an expert, as opposed to when an expert uttered the minor premise and a novice denied it (Experiment 3). Experiment 4 showed that the nature of the uncertainty induced by a denial of the minor premise depended on whether or not the context was a conversation. These results pose difficult problems for current theories of reasoning, as current theories are based on the results of experiments in which the premises are treated as certain. Our discussion of the results emphasises the importance of pragmatics in reasoning, namely, the role of general knowledge about the world in assessing the probability of a premise uttered by an expert or a novice and the role of interpretations of the premise based on pragmatic inferences in revising these initial probabilities.

This volume represents the proceedings of the annual Lectures on Moral Values in a Free Society at the University of Texas at Dallas, presented in 1983 on November 14 through 16.

Buddhisms and Deconstructions considers the connection between Buddhism and Derridean deconstruction, focusing on the work of Robert Magliola. Fourteen distinguished contributors discuss deconstruction and various Buddhisms—Indian, Tibetan, and Chinese —followed by an afterword in which Magliola responds directly to his critics.

The words “atone” and “atonement,” if employed at all in these days of somewhat loose morals, tend to refer to an action to make up for some misdeed. One realizes that what one did was wrong, and one may “repent” or at least feel regret, so that apology, perhaps restitution, is appropriate; maybe even some sort of “penance”, i.e., a task or sacrifice to show the reality of one’s regret. There is a related meaning listed in the Oxford English Dictionary, (...) namely the reconciliation of two people or parties in some kind of conflict or estrangement. Apology, restitution, or penance are intended to promote at-one-ment, but there is no.. (shrink)

The philosophy of Epicurus (c. 341-271 B. C. E.), has been a quietly pervasive influence for more than two millennia. At present, when many long revered ideologies are proven empty, Epicureanism is powerfully and refreshingly relevant, offering a straightforward way of dealing with the issues of life and death. The chapters in this book provide a kaleidoscope of contemporary opinions about Epicurus' teachings. They tell us also about the archeological discoveries that promise to augment the scant remains we have of (...) Epicurus's own writing. the breadth of this new work will be welcomed by those who value Epicurean philosophy as a scholarly and personal resource for contemporary life. "Epicurus: His Continuing Influence and Contemporary Relevance," is the title of a 2002 conference on Epicurus held at Rochester Institute of Technology, when many of the ideas here were first presented.

Examination of recent debates about belief shows the need to distinguish: (a) non-linguistic informational states in animal perception; (b) the uncritical use of language, e.g. by children; (c) adult humans' reasoned judgments. If we also distinguish between mind-directed and object-directed mental states, we have: Perceptual 'beliefs' of animals and infants about their material environment. 'Beliefs' of animals and infants about the mental states of others. Linguistically-expressible beliefs about the world, resulting from e.g. the uncritical tendency to believe what we are (...) told. Uncritically-formed beliefs about the mental states. Beliefs about the material world arrived at by the weighing of evidence. Beliefs about mental states formed by critical assessment. (shrink)

This paper examines the applicability of the object concept to the chemical senses, by evaluating them against a set of criteria for object‐hood. Taste and chemesthesis do not generate objects. Their parts, perceptible from birth, never combine. Orthonasal olfaction (sniffing) presents a strong case for generating objects. Odorants have many parts yet they are perceived as wholes, this process is based on learning, and there is figure‐ground segregation. While flavors are multimodal representations bound together by learning, there is no functional (...) need for flavor objects in the mouth. Rather, food identification occurs prior to ingestion using the eye and nose, with the latter retrieving multimodal flavor objects via sniffing (e.g.,sweetsmelling caramel). While there are differences in object perception between vision, audition, and orthonasal olfaction, the commonalities suggest that the brain has adopted the same basic solution when faced with extracting meaning from complex stimulus arrays.

Over three previous editions, Ten Theories of Human Nature has been a remarkably popular introduction to some of the most influential developments in Western and Eastern thought. This thoroughly revised fourth edition features substantial new chapters on Aristotle and on evolutionary theories of human nature; the latter centers on Edward O. Wilson but also outlines the ideas of Emile Durkheim, B. F. Skinner, Nikolaas Tinbergen, Konrad Lorenz, Noam Chomsky, and recent evolutionary psychology. This edition also includes a rewritten introduction that (...) invites readers (even if inclined toward fundamentalism, or to cultural relativism) to careful, critical thought about human nature; a useful new section that summarizes the history of ideas from the Stoics to the Enlightenment; and a new conclusion that suggests a way to synthesize the various theories. Lucid and accessible, Ten Theories of Human Nature, 4/e, compresses into a small space the essence of such ancient traditions as Confucianism, Hinduism, and the Old and New Testaments as well as the theories of Plato, Immanuel Kant, Karl Marx, Sigmund Freud, and Jean-Paul Sartre. The authors juxtapose the ideas of these and other thinkers and traditions in a way that helps readers understand how humanity has struggled to comprehend its nature. To encourage readers to think critically for themselves and to underscore the similarities and differences between the many theories, the book examines each one on four points--the nature of the universe, the nature of humanity, the diagnosis of the ills of humanity, and the proposed cure for these problems. Ideal for introductory courses in human nature, philosophy, religious studies, and intellectual history, Ten Theories of Human Nature, 4/e, will engage and motivate students and other readers to consider how we can understand and improve both ourselves and human society.

In lieu of an abstract, here is a brief excerpt of the content:February 19, 2011 (11:48 am) E:\CPBR\RUSSJOUR\TYPE3002\russell 30,2 040 red.wpd Reviews 179 THE EARLY “IRON CURTAIN” Michael D. Stevenson Schulich School of Business, York U. / Russell Research Centre, McMaster U. Toronto, on m3j 1p3 / Hamilton, on l8s 4l6, Canada [email protected] Patrick Wright. Iron Curtain: from Stage to Cold War. Oxford: Oxford U. P., 2007. Pp. xvii, 488. isbn 978-0-19-923150-8. £18.99 (hb); £12.99 (pb). In his famous Westminster (...) College address on 5 March 1946 in Fulton, Missouri, Winston Churchill Wred one of the opening salvos of the Cold War by proclaiming that from “Stettin in the Baltic to Trieste in the Adriatic an iron curtain” had been lowered across Europe. Patrick Wright’s intriguing and provocative book does not examine the phrase “iron curtain” in its popular Cold War context. Instead, he maintains that many characteristics of this metaphor, “including the pronounced sense of theatricality it would bring to international politics, were inherited from the period before the Second World War” (p. 18). Wright divides Iron Curtain into two primary chronological sections, the Wrst covering the period from 1914 to 1920. An iron curtain originally referred to the steel safety screen that descended in English theatres, beginning in the lateeighteenth century, to separate the audience from the often catastrophic Wres that broke out on the stage. The phrase entered the lexicon of international relations in January 1915 when British author and paciWst Violet Page (writing under the pseudonym Vernon Lee) published an article lamenting that “War’s cruelties and recriminations, War’s monstrous iron curtain” (p. 80) had alienated European nations such as England and Germany sharing a common cultural heritage. But the barrier quickly moved east in the aftermath of the 1917 Russian Revolution and “took the form not just of exaggerated political rhetoric, but of an economic blockade enforced by naval power” (p. 171), as the Allies sought to contain the infection of Bolshevism. Wright devotes most attention in this section to documenting the 1920 visit to Russia by the British delegation jointly sponsored by the Trades Union Congress and the Labour Party, which sought to penetrate the dense fog of Allied anti-Bolshevik propaganda and validate the delegation members’ own preconceived views about the nascent socialist utopia in Russia. British delegates witnessed images both of progress carefully stagemanaged by their hosts and of terrible economic dislocation and poverty caused by the Allied blockade and the civil war, which allowed the majority of them to return home to lavish praise on the Soviet experiment that would, in their minds, inevitably fulWl its potential once the Bolshevik government became stable.

The second section of Wright’s book examines Western reports of life behind the iron curtain between 1920 and 1939. Here, the author focuses heavily on the theatrical nature of Soviet attempts to create modern-day Potemkin villages that werez—zwith a limited number of exceptionsz—zaccepted as reality by an endless parade of left-wing visitors. A second British Trades Union Congress delegation in 1924, for example, received a dramatically embellished picture of Soviet economic progress that included a train journey past a long-abandoned factory belching smoke created by burning wet straw frantically provided by Russian peasants; the resulting report of the delegation “repeatedly collapsed into the most abject conformity with the Soviet view of reality” (p. 245). The most tragic examples of Western visitors’ blindness to the truth occurred during the 1930s famine deliberately induced by Stalin, and Wright exposes a wide cast of characters who adopted a blinkered view of conditions in the ussr. Among intellectuals, Wright documents the 1931 visit of George Bernard Shaw, who cavalierly dismissed reports of widespread food shortages while dining sumptuously in Moscow’s Hotel Metropole. Among journalists, Wright develops the case of Walter Duranty, the New York Timesz correspondent who knuckled under to demands of Soviet censors to produce sanitized accounts denying or ignoring the famine in order to protect his privileged place in that...

The second edition of this exceptional anthology provides an introduction to a wide variety of views on human nature. Drawing from diverse cultures over three millennia, Leslie Stevenson has chosen selections ranging from ancient religious texts to contemporary theories based on evolutionary science. An ideal companion to the editor's recent book, Ten Theories of Human Nature, 3/e (OUP, 1998), this interdisciplinary reader can also be used independently. The Study of Human Nature, 2/e offers substantial selections illustrating the ten perspectives (...) discussed in Ten Theories of Human Nature, 3/e--The Bible, Hinduism, Confucianism, Plato, Kant, Marx, Freud, Sartre, B.F. Skinner's behaviorism, and Konrad Lorenz's ethological diagnosis of human aggression. The Islamic tradition is represented by a selection from the 20th-century Iranian philosopher Ayatullah Murtaza Mutahhari. The 17th- and 18th-century philosophers Descartes, Hobbes, Hume, Rousseau, and Kant are also represented. Selections from Rousseau, J.S. Mill, and Nancy Holmstrom discuss alleged differences between women and men, and a paper by Henry Bracken deals with racial issues. Examples from E.O. Wilson's sociobiology and his critics are also included, together with material from Chomsky and from recent evolutionary psychology. This new edition includes more substantial selections from the Hindu, Confucian, and Christian traditions and provides more accessible extracts from Marx, Sartre, and Lorenz. An excellent reader for introductory courses in philosophy, religious studies, human nature, and intellectual history, The Study of Human Nature, 2/e, is also an essential resource for anyone interested in ancient, modern, and contemporary perspectives on human nature.

Neonatal brain monitoring in the neonatal intensive care units (NICU) requires a continuous review of the spontaneous cortical activity, i.e., the electroencephalograph (EEG) background activity. This needs development of bedside methods for an automated assessment of the EEG background activity. In this paper, we present development of the key components of a neonatal EEG background classifier, starting from the visual background scoring to classifier design, and finally to possible bedside visualization of the classifier results. A dataset with 13,200 5-minute EEG (...) epochs (8–16 channels) from 27 infants with birth asphyxia was used for classifier training after scoring by two independent experts. We tested three classifier designs based on 98 computational features, and their performance was assessed with respect to scoring system, pre- and post-processing of labels and outputs, choice of channels, and visualization in monitor displays. The optimal solution achieved an overall classification accuracy of 97% with a range across subjects of 81–100%. We identified a set of 23 features that make the classifier highly robust to the choice of channels and missing data due to artefact rejection. Our results showed that an automated bedside classifier of EEG background is achievable, and we publish the full classifier algorithm to allow further clinical replication and validation studies.

Birds are not commonly admired for emotional expression, and when they are, the focus is typically on negative states; yet vocal behavior is considered a direct reflection of an individual’s emotional state. Given that over 4000 species of songbird produce learned, complex, context-specific vocalizations, we make the case that songbirds are conspicuously broadcasting distinct positive emotional states and that hearing songs can also induce positive states in other birds. Studies are reviewed that demonstrate that that the production of sexually motivated (...) song reflects an emotional state of anticipatory reward-seeking (i.e., mate-seeking), while outside the mating context song in gregarious flocks reflects a state of intrinsic reward. Studies are also reviewed that demonstrate that hearing song induces states of positive anticipation and reward. This review brings together numerous studies that highlight a potentially important role for the songbird nucleus accumbens, a region nearly synonymous with reward in mammals, in positive emotional states that underlie singing behavior and responses to song. It is proposed that the nucleus accumbens is part of an evolutionarily conserved circuitry that contributes context-dependently to positive emotional states that motivate and reward singing behavior and responses to song. Neural mechanisms that underlie basic emotions appear to be conserved and similar across vertebrates. Thus, these findings in songbirds have the potential to provide insights into interventions that can restore positive social interactions disrupted by mental health disorders in humans. (shrink)

By addressing specific global problems and placing them within an ethical context, "The Environment in Question" provides the reader with both a theoretical and practical understanding of environmental issues. The contributors are internationally known figures drawn from the various disciplines which bear upon these issues, such as geography, psychology, social policy, and philosophy. The contributions range from those tackling individual concrete issues (such as nuclear waste and the threat to the rain forest) to those addressing matters of policy, principle and (...) attitude (such as our obligations to future generations and the nature of technological risk). "The Environment in Question" is designed as a text for students of philosophy, environmental science, environmental education, ecology, and teacher education. It can be used as an inter-disciplinary, self-contained course book or in conjunction with relevant material. In addition, as the essays directly and controversially address current environmental debates in a non-technical manner, it is of great interest both to professionals in those areas and to readers who care about the planet's future. The substantial cross-section of concerns and approaches will enable all readers to develop the necessary level of understanding required to initiate and sustain debate on environmental issues.
