Computational models of learning provide an alternative technique for identifying the number and type of chunks used by a subject in a specific task. Results from applying CHREST to chess expertise support the theoretical framework of Cowan and a limit in visual short-term memory capacity of 3–4 looms. An application to learning from diagrams illustrates different identifiable forms of chunk.

We discuss the relation of the Theory of Event Coding (TEC) to a computational model of expert perception, CHREST, based on the chunking theory. TEC's status as a verbal theory leaves several questions unanswerable, such as the precise nature of internal representations used, or the degree of learning required to obtain a particular level of competence: CHREST may help answer such questions.

Pioneering work in the 1940s and 1950s suggested that the concept of chunking might be important in many processes of perception, learning and cognition in humans and animals. We summarize here the major sources of evidence for chunking mechanisms, and consider how such mechanisms have been implemented in computational models of the learning process. We distinguish two forms of chunking: the first deliberate, under strategic control, and goal-oriented; the second automatic, continuous, and linked to perceptual processes. Recent work with discrimination-network (...) computational models of long- and short-term memory (EPAM/CHREST) has produced a diverse range of applications of perceptual chunking. We focus on recent successes in verbal learning, expert memory, language acquisition and learning multiple representations, to illustrate the implementation and use of chunking mechanisms within contemporary models of human learning.

Most academics agree that emotions and moods are related but distinct phenomena. The present study assessed emotion-mood distinctions among a non-academic population and compared these views with distinctions proposed in the literature. Content analysis of responses from 106 participants identified 16 themes, with cause (65% of respondents), duration (40%), control (25%), experience (15%), and consequences (14%) the most frequently cited distinctions. Among 65 contributions to the academic literature, eight themes were proposed, with duration (62% of authors), intentionality (41%), cause (31percnt;), (...) consequences (31%), and function (18%) the most frequently cited. When the eight themes cited by both academics and non-academics were rank ordered, approximately 60% overlap in opinion was evident. A data-derived summary of emotion-mood distinctions is provided. These data should prove useful to investigators interested in developing a clearer scientific distinction between emotion and mood than is currently available. (shrink)

The Hegel Lectures Series Series Editor: Peter C. Hodgson Hegel's lectures have had as great a historical impact as the works he himself published. Important elements of his system are elaborated only in the lectures, especially those given in Berlin during the last decade of his life. The original editors conflated materials from different sources and dates, obscuring the development and logic of Hegel's thought. The Hegel Lectures series is based on a selection of extant and recently discovered transcripts (...) and manuscripts. Lectures from specific years are reconstructed so that the structure of Hegel's argument can be followed. Each volume presents an accurate new translation accompanied by an editorial introduction and annotations on the text, which make possible the identification of Hegel's many allusions and sources. Hegel's Lectures on the Philosophy of Religion represent the final and in some ways the decisive element of his entire philosophical system. His conception and execution of the lectures differed significantly on each of the occasions he delivered them, in 1821, 1824, 1827, and 1831. The older editions introduced insoluble problems by conflating these materials into an editorially constructed text. The present volumes establish a critical edition by separating the series of lectures and presenting them as independent units on the basis of a complete re-editing of the sources by Walter Jaeschke. The English translation has been prepared by a team consisting of Robert F. Brown, Peter C. Hodgson, and J. Michael Stewart, with the assistance of H. S. Harris. Now widely recognized as the definitive English edition, it is being reissued by Oxford in the Hegel Lectures Series. The three volumes include editorial introductions, critical annotations on the text, textual variants, and tables, bibliography, and glossary. 'The Consummate Religion' is Hegel's name for Christianity, which he also designates 'the Revelatory Religion'. Here he offers a speculative interpretation of major Christian doctrines: the Trinity, creation, humanity, estrangement and evil, Christ, the Spirit, the spiritual community, church and world. These interpretations have had a powerful and controversial impact on modern theology. (shrink)

This volume a translation of a mid-nineteenth century work on the history of Christian dogma by Ferdinand Christian Baur, who brilliantly applied Hegelian categories to his historical studies in New Testament, church history, and history of Christian dogma. "Dogma" for him is the rational articulation of the Christian "idea" or principle-the idea that God and humanity are united in Christ and reconciled through the faith of the spiritual community. Baur offers a unique perspective on the whole of Christian intellectual history, (...) and readers will find that his detailed analyses provide a wealth of information on individual thinkers and doctrines that is still relevant today.

These lectures constitute the earliest version of Hegel's Philosophy of Right, one of the most influential works in Western political theory. They introduce a notion of civil society that has proven of inestimable importance to diverse philosophical and social agendas. This transcription of the lectures, which remained in obscurity until 1982, presents the philosopher's social thought with clarity and boldness. It differs in some significant respects from Hegel's own published version of 1821. Nowhere does Hegel make plainer the difference between (...) his concept of objective spirit and traditional concepts of natural law or offer a more prominent treatment of the key notion of recognition. His description of poverty is more forceful and his critique of existing social conditions more thorough than in the published edition, which had to satisfy the Prussian censor. The strictly limited powers of the monarch are more clearly delineated in the Heidelberg lectures, and the arguments for a bicameral legislature are more explicit. Hegel formulates in a more dynamic way his understanding of the relationship between rationality and actuality--the rational is not what exists but what is coming into being--and sets forth more simply and clearly the central themes of his political philosophy--freedom, justice, and community. The Heidelberg lectures are an indispensable resource for understanding the edition of 1821 and an invaluable supplement to one of the great classics of political philosophy. (shrink)

Peter C. Hodgson engages the speculative reconstruction of Christian theology that is accomplished by Hegel's Lectures on the Philosophy of Religion, and provides a close reading of the critical edition of the lectures. He analyses Hegel's concept of the object and purpose of the philosophy of religion, his critique of the theology of his time, his approach to Christianity within the framework of the concept of religion, his concept of God, his reconstruction of central Christian themes, and his placing (...) of Christianity among the religions of the world. Hodgson makes a case for the contemporary theological significance of Hegel by identifying currently contested sites of interpretation and their Hegelian resolution. (shrink)

H. B. Smith, Professor of Philosophy at the influential 'Pennsylvania School' was (roughly) a contemporary of C. I. Lewis who was similarly interested in a proper account of 'implication'. His research also led him into the study of modal logic but in a different direction than Lewis was led. His account of modal logic does not lend itself as readily as Lewis' to the received 'possible worlds' semantics, so that the Smith approach was a casualty rather than a beneficiary of (...) the renewed interest in modality. In this essay we present some of the main points of the Smith approach, in a new guise. (shrink)

This paper develops the concept of the ‘continuum of destructiveness’ in relation to organizational corruption. This notion captures the slippery slope of wrongdoing as actors engage in increasingly dubious practices. We identify four kinds of individuals along this continuum in corrupt organizations, who range from complete innocence to total guilt. They are innocent bystanders, innocent participants, active rationalizers and guilty perpetrators. Traditional explanations of how individuals move from bystander status to guilty perpetrators usually focus on socialization and institutional factors. In (...) addition to these factors, we propose that the very distance between an act and its ethical consequences (ethical distance) may also play a determining role – if not always in the same way – in the transition process. Having developed this conceptual argument, we conclude with a discussion of managerial and research implications. (shrink)

The Constitution of Independence is a contribution to the newly rejuvenated subject of comparative Commonwealth constitutional law, politics, and history. In Australia, Canada, and New Zealand, a series of fascinating developments have been under way for more than a decade, characterized by independent thinking, experimentation, and cross-Commonwealth borrowing of constitutional ideas. These include the final termination of constitutional ties with the United Kingdom Parliament and the emergence of controversial issues including variably entrenched or implied rights and freedoms; wide-ranging claims by (...) indigenous peoples; republicanism; and assertions of national, popular, and sectional sovereignty.This book explores the development of constitutional thinking in Australia, Canada, and New Zealand from early domination by Imperial ideas, through the adoption of the Statute of Westminster and the contemplation of severing Imperial connections, to irreversible acquisition of constitutional independence in the 1980s. This book focusses primarily on sovereignty and the legal system, concepts which are also central to contemporary constitutional theory in Europe and the United States. The book closes with an evaluation of recent varied and often contradictory accounts of the constitutional foundations of Australia, Canada, and New Zealand, which depict a wide range of scenarios: from constitutional continuity and respect for the rule of law, to popular sovereignty and disguised revolution. Oliver argues that explanations of constitutional independence are characterized by their reliance on independent, country-specific constitutional thinking that evolved over the last century. on.

Many of us are inclined to accept something like the following principle: We can only be properly morally assessed for what is in our control. And yet our ordinary practices seem to frequently violate this principle. The resulting tension, and the attempt to resolve it, is the problem of moral luck. For example, we tend to punish and think worse of the negligent driver who kills a child than we do the equally negligent driver who was lucky there was no (...) child in his path. Thus, the lucky outcomes of our actions do seem to affect the extent to which we hold and are held responsible, but these are not things over which we exercise control. And, as Thomas Nagel famously illustrated in his response to Bernard Williams (the two of which papers form the founding documents of the moral luck debate), the influence of luck is not limited to outcomes. For the circumstances in which we find ourselves and, indeed, our very constitution are also shaped by luck. Since the publication of Williams's and Nagel's papers, the existence and breadth of moral luck has been hotly debated. This debate is not a mere intellectual trifle but, as the essays in this volume illustrate, a debate which lies at the heart of free will, responsibility, identity, causation, and self-creation.

The Lectures on the Philosophy of Religion represent the final and in some ways the decisive element of Hegel's entire philosophical system. His conception and execution of these crucial lectures differed so significantly on each of the occasions he delivered them - in 1821, 1824, 1827, and 1831 - that it is impossible, without destroying the structural integrity of the lectures, to conflate material from different years into an editorially constructed text. These volumes establish for the first time a critical (...) edition, separating the series of lectures and publishing them as autonomous units on the basis of a complete re-editing of the sources. Volume I contains Hegel's Introduction and Part I. (shrink)

Three experiments examined repetition priming for meaningful environmental sounds in a sound stem identification paradigm using brief sound cues. Prior encoding of target sounds together with their associated names facilitated subsequent identification of sound stems relative to nonstudied controls. In contrast, prior exposure to names alone in the absence of the environmental sounds did not prime subsequent sound stem identification performance at all . Explicit and implicit memory were dissociated such that sound stem cued recall was higher following semantic than (...) nonsemantic encoding, whereas sound priming was insensitive to manipulations of depth encoding . These results extend the findings of long-term repetition priming into the auditory nonverbal domain and suggest that priming for environmental sounds is mediated primarily by perceptual processes.

Peter C. Hodgson provides a new translation of Hegel's 1829 lectures on the proofs of the existence of God, based on the definitive German edition. Coming late in his career, these lectures give us the great philosopher's final and most seasoned thinking on a topic of obvious significance to him, that of the reality status of God and ways of knowing God.

Business Ethics, the Environment & Responsibility, EarlyView.

There is a large amount of scientific work on emotion in psychology, neuroscience, biology, physiology, and psychiatry, which assumes that it is possible to study emotions and other affective states, objectively. Emotion science of this sort is concerned primarily with 'facts' and not 'values', with 'description' not 'prescription'. The assumption behind this vision of emotion science is that it is possible to distinguish factual from evaluative aspects of affectivity and emotion, and study one without the other. But what really is (...) the basis for distinguishing fact and value in emotion and affectivity? And can the distinction withstand careful scientific and philosophical scrutiny? The essays in this collection all suggest that the problems behind this vision of emotion science may be more complex than is commonly supposed. (shrink)

An important area of business ethics research focuses on how otherwise normal and law-abiding individuals can engage in acts of corruption. Key in this literature is the concept of rationalization. This is where individuals attempt to justify past and future corrupt deeds to themselves and others. In this article, we argue that rationalization often entails a process of overcompensation whereby the justification forwarded is excessive in relation to the actual act. Such over-rationalization provides an impetus for further and more serious (...) acts of illegality. Using a number of high profile cases, it is argued that this dynamic gap between the act and excessive rationalization can explain why corruption often escalates in severity and scope in the organization.

Treatment of military-related posttraumatic stress disorder is a major public health care concern. Since 2001 over 2.5 million troops have been deployed to Iraq or Afghanistan, many of whom have experienced direct combat and sustained threat. Estimates of PTSD rates related to these wars range from 8% to over 20%, or 192,000 to 480,000 individuals. Already, nearly 250,000 service members of Operations Enduring Freedom, Iraqi Freedom, and New Dawn have sought VA health care services for PTSD. This recent increased need (...) for mental health services comes in addition to the ongoing needs of Vietnam-era and other veterans who continue to suffer from PTSD. PTSD is related to high co-morbidities of other mental health difficulties, poorer physical health status, and increased medical care utilization. Such high demand for services is an important contributor to the large cost associated with combat-related PTSD. Accordingly, promoting successful, cost-effective treatment strategies for PTSD is a chief public health care priority. (shrink)

Randomized controlled clinical trials play an important role in the development of new medical therapies. There is, however, an ethical issue surrounding the use of randomized treatment allocation when the patient is suffering from a life threatening condition and requires immediate treatment. Such patients can only benefit from the treatment they actually receive and not from the alternative therapy, even if it ultimately proves to be superior. We discuss a novel new way to analyse data from such clinical trials based (...) on the use of the recently developed theory of imprecise probabilities. This work draws an explicit distinction between the related but nevertheless distinct questions of inference and decision in clinical trials. The traditional question of scientific interest asks 'Which treatment offers the greater chance of success?' and is the primary reason for conducting the clinical trial. The question of decision concerns the welfare of the patients in the clinical trial, asking whether the accumulated evidence favours one treatment over the other to such an extent that the next patient should decline randomization and instead express a preference for one treatment. Consideration of the decision question within the framework of imprecise probabilities leads to a mathematical definition of equipoise and a method for governing the randomization protocol of a clinical trial. This paper describes in detail the protocol for the conduct of clinical trials based on this new method of analysis, which is illustrated in a retrospective analysis of data from a clinical trial comparing the anti-emetic drugs ondansetron and droperidol in the treatment of postoperative nausea and vomiting. The proposed methodology is compared quantitatively using computer simulation studies with conventional clinical trial designs and is shown to maintain high statistical power with reduced sample sizes, at the expense of a high type I error rate that we argue is irrelevant in some specific circumstances. Particular emphasis is placed on describing the type of medical conditions and treatment comparisons where the new methodology is expected to provide the greatest benefit. (shrink)

Culture, defined as shared behavior or information within a community acquired through some form of social learning from conspecifics, is now suggested to act as a second inheritance system. Cultural processes are important in a wide variety of vertebrate species. Birdsong provides a classic example of cultural processes: cultural transmission, where changes in a shared song are learned from surrounding conspecifics, and cultural evolution, where the patterns of songs change through time. This form of cultural transmission of information has features (...) that are different in speed and form from genetic transmission. More recently, culture, vocal traditions and an extreme form of song evolution has been documented in cetaceans. Humpback whale song ‘revolutions’, where the single population-wide shared song type is rapidly replaced by a new, novel song type introduced from a neighbouring population, represents an extraordinary example of ocean basin-wide cultural transmission rivalled in its geographic extent only by humans. In this review, we examine the cultural evolutions and revolutions present in some birdsong and whale song, respectively. By taking a comparative approach to these cultural processes, we review the existing evidence to understand the similarities and differences for their patterns of expression and the underlying drivers, including anthropogenic influences, which may shape them. Finally, we encourage future studies to explore the role of innovation vs. production errors in song evolution, the fitness information present in song, and how human-induced changes in population sizes, trajectories and migratory connections facilitating cultural transmission may be driving song revolutions.

People make significant decisions in contexts of risk and uncertainty. Some of these decisions seem wise under the circumstances, and others seem like irrational choices. In both cases, people offer reasons as clarifications and explanations of these choices to others and to themselves. Argument analysis, a technique well known in philosophy and more generally in the humanities, can explicate the strands of assumptions, intermediate conclusions, data, warrants, and claims that the person articulates. But alone, argument analysis often falls short of (...) revealing why the person’s decision makes sense to that person. Thefindings of empirical research into the influences of cognitive heuristics, the mental shortcuts we all use in decision making and problem solving, adds focus to the analysis of these choices. This paper links these two powerful analytic strategies, and provides a much fuller, more fruitful picture of explanations for seemingly irrational choices. Using an example explanation for deciding not to quit smoking, the paper makes both its methodological argument and its implicit argument for the significance of extending this analytical strategy to applied contexts. The implications of extending this analysis of everyday argument to management, health care, and education could be profound. (shrink)

Modern humans are probably a product of social and anatomical preadaptations on the part of our Miocene australopithecine ancestors combined with the increasingly high amplitude, high frequency climate variation of the Pleistocene. The genus Homo first appeared in the early Pleistocene as ice age climates began to grip the earth. We hypothesize that this co-occurrence is causal. The human ability to adapt by cultural means is, in theory, an adaptation to highly variable environments because cultural evolution can better track rapidly (...) changing environments than can genes. High resolution ice and sediment cores published in the early 1990s showed the last ice age was characterized by high amplitude millennial and submillenial scale variation, exactly the sort of variation mathematical models suggest should favor a costly capacity for culture. More recent cores suggest that over the last several 100 thousand year glacial cycles the amount of millennial scale variation has increased rather dramatically in parallel with increases in hominin brain size and sophistication of the artifacts they made.
