In recent years, Bayesian probability theory has emerged not only as a powerful tool for building computational theories of vision, but also as a general paradigm for studying human visual perception. This book provides an introduction to and critical analysis of the Bayesian paradigm. Leading researchers in computer vision and experimental vision science describe general theoretical frameworks for modeling vision, detailed applications to specific problems and implications for experimental studies of human perception. The book provides a dialogue between different perspectives (...) both within chapters, which draw on insights from experimental and computational work, and between chapters, through commentaries written by the contributors on each other's work. Students and researchers in cognitive and visual science will find much to interest them in this thought-provoking collection. (shrink)

To provide the three-way comparisons needed to test existing theories, we compared (1) most-stressful memories to other memories and (2) involuntary to voluntary memories (3) in 75 community dwelling adults with and 42 without a current diagnosis of posttraumatic stress disorder (PTSD). Each rated their three most-stressful, three most-positive, seven most-important and 15 word-cued autobiographical memories, and completed tests of personality and mood. Involuntary memories were then recorded and rated as they occurred for 2 weeks. Standard mechanisms of cognition and (...) affect applied to extreme events accounted for the properties of stressful memories. Involuntary memories had greater emotional intensity than voluntary memories, but were not more frequently related to traumatic events. The emotional intensity, rehearsal, and centrality to the life story of both voluntary and involuntary memories, rather than incoherence of voluntary traumatic memories and enhanced availability of involuntary traumatic memories, were the properties of autobiographical memories associated with PTSD.

Participants with posttraumatic stress disorder and participants with a trauma but without PTSD wrote narratives of their trauma and, for comparison, of the most-important and the happiest events that occurred within a year of their trauma. They then rated these three events on coherence. Based on participants’ self-ratings and on naïve-observer scorings of the participants’ narratives, memories of traumas were not more incoherent than the comparison memories in participants in general or in participants with PTSD. This study comprehensively assesses narrative (...) coherence using a full two by two design. The results are counter to most prevalent theoretical views of memory for trauma. (shrink)

Increasingly, the world seems to shrink due to our ever-expanding technological and communication capacities. Correspondingly, our awareness of other cultures increases. This is especially true in the field of bioethics because the technological progress of medicine throughout the world is causing dramatic and challenging intersections with traditionally held values. Think of the use of pregnancy monitoring technologies like ultrasound to abort fetuses of the “wrong” sex in India, the sale of human organs in and between countries, or the disjunction between (...) the haves and the have-nots in South America when it comes to bone marrow transplants, while thousands of other children die for want of fundamental goods and services like clean water, basic inoculations, and food itself.

: Faraday is often described as an experimentalist, but his work is a dialectical interplay of concrete objects, visual images, abstract, theoretically-informed visual models and metaphysical precepts. From phenomena described in terms of patterns formed by lines of force he created a general explanation of space-filling systems of force which obey both empirical laws and principles of conservation and economy. I argue that Faraday's articulation of situated experience via visual models into a theory capable of verbal expression owed much to (...) his strategy of moving—via conjectural visual models—between the phenomenology of particulars (often displayed as patterns) and the general features of dynamical phenomena which he depicted as structures.

There are several branches of ethics. Clinical ethics, the one closest to medical decisionmaking, can be seen as a branch of medicine itself. In this view, clinical ethics is a unitary hermeneutics. Its rule is a guideline for unifying other theories of ethics in conjunction with the clinical context. Put another way, clinical ethics interprets the clinical situation in light of a balance of other values that, while guiding the decisionmaking process, also contributes to the very weighting of those values. (...) The case itself originates ideas, not only about which value ought to predominate in its resolution, but also provides the origin of clinical rules that can be used in other cases. These are interpretive rules. Some examples of these rules are presented as well. (shrink)

This study evaluated the online privacy policies of business-to-consumer e-commerce firms in five industries of mainland China, Taiwan, and Hong Kong. Based on the neo-institutional theory, we also tested whether the four institutional factors, top management’s legal education, managerial ethics, rule of law in information privacy protection and peer practices, had any effects on e-information and e-communication content. Results from a content analysis of 229 websites found that the privacy policy contents that complied with generally accepted privacy standards were lesser (...) in mainland China firms than those of Taiwan and Hong Kong firms. There were also significant differences in the amount of contents among the five industries. The results of regression analyses showed the importance of all four factors on e-information content. They also showed the importance of coercive, mimetic, and normative isomorphisms on e-information content. The validation of normative isomorphism highlighted the importance of managerial ethics and legal education. Our findings supplemented extant literature which identified economic motive as the main factor in influencing privacy practice disclosures. (shrink)

I offer a critical analysis of a view that has become a dominant aspect of recent thought on the relationship between evolution and morality, and propose an alternative. An ingredient in Michael Ruse's 'error theory' (Ruse 1995) is that belief in moral (prescriptive, universal, and nonsubjective) guidelines arose in humans because such belief results in the performance of adaptive cooperative behaviors. This statement relies on two particular connections: between ostensible and intentional types of altruism, and between intentional altruism and morality. (...) The latter connection is problematic because it makes morality redundant, its role having already been fulfilled by the psychological dispositions that constitute intentional altruism. Both behavioral ecology and moral psychology support this criticism, and neither human behavioral flexibility nor the self-regard / other-regard distinction can provide a defense of the error theory. I conclude that morality did not evolve to curb rampant selfishness; instead, the evolutionarily recent 'universal law' aspect of morality may function to update behavioral strategies which were adaptive in the paleolithic environment of our ancestors (to which our psychological dispositions are best adapted), by means of norms more appropriate to our novel social environment.

I argue that thought experiments are a form of experimental reasoning similar to real experiments. They require the same ability to participate by following a narrative as real experiments do. Participation depends in turn on using what we already know to visualize, manipulate and understand what is unfamiliar or problematic. I defend the claim that visualization requires embodiment by an example which shows how tacit understanding of the properties of represented objects and relations enables us to work out how such (...) objects might behave in a postulated world. This knowledge is that of embodied agents. That thought experiments require embodied participation is what makes them experiments rather than arguments. Unlike real experiments, from which ordinary perception has been displaced by instrumentation, thought experiments still appeal to relatively unmediated common sense, even when their purpose is to criticize or subvert common sense notions.

While prior research suggests a link between mindfulness and ethical decision-making, most of the evidence for this link is correlational and refers to self-focused ethical behaviors. The paucity of experimental evidence, coupled with a lack of clarity on what mechanisms underlie the effect, limits our understanding of whether and how mindfulness might foster other-focused ethical behaviors. In this research, we hypothesize that state mindfulness might promote other-focused ethical behaviors by increasing resourcefulness, which we define as a perceived state of resource (...) abundance. Across four experimental studies, we report causal evidence for the effects of state mindfulness instantiated through brief mindful meditation exercises on other-focused ethical behaviors, including choice of fair-trade products, charitable giving, and volunteering. Resourcefulness mediates the effects of mindfulness on other-focused ethical behaviors. Our work answers the call for more experimental research on mindfulness and its important implications for ethical decision-making. (shrink)

In June 1993, conjoined twins Amy and Angela Lakeberg became the focus of national attention. They shared a complex six‐chambered heart and one liver; only one could survive separation surgery, and even her chances were slim. The medical challenge was great and the ethical challenges were even greater.

A position has been advanced by a number of philosophers, notably by Burnham and Skilleås, that certain knowledge is required to aesthetically appreciate a fine wine. They further argue that pleasure is not an integral part of aesthetically appreciating wine. Their position implies that a novice cannot aesthetically appreciate a fine wine. This paper draws on research into tasting and psychology to rebut these claims. I argue that there is strong evidence from both the average consumer and from wine experts (...) that they are unable to separate enjoyment from aesthetic evaluation; secondly, I argue that wine knowledge may actually preclude tasting of the wine as it exists in the glass due to perceptual bias. I conclude by arguing that it is unclear how exactly knowledge of things like terroir is supposed to affect the taste, as well as question what role conforming to a certain style plays in aesthetic success, as arguments that require knowledge for appreciation typically emphasize knowledge of styles of wine.

William James is frequently considered one of America's most important philosophers, as well as a foundational thinker for the study of religion. Despite his reputation as the founder of pragmatism, he is rarely considered a serious philosopher or religious thinker. In this new interpretation David Lamberth argues that James's major contribution was to develop a systematic metaphysics of experience integrally related to his developing pluralistic and social religious ideas. Lamberth systematically interprets James's radically empiricist world-view and argues for an (...) early dating for his commitment to the metaphysics of radical empiricism. He offers a close reading of Varieties of Religious Experience; and concludes by connecting James's ideas about experience, pluralism and truth to current debates in philosophy, the philosophy of religion, and theology, suggesting James's functional, experiential metaphysics as a conceptual aid in bridging the social and interpretive with the immediate and concrete while avoiding naive realism.

We seek a better understanding of why an inferential semantics devised by Tor Sandqvist yields full classical logic, by providing and analysing a direct proof via a suitable maximality construction.

Like most other sciences, behavior analysis adopts an assumption of uniformity, namely that principles discovered under controlled conditions apply outside the laboratory as well. Since the boundary between public and private depends on the vantage point of the observer, observability is not an inherent property of behavior. From this perspective, private events are assumed to enter into the same orderly relations as public behavior, and the distinction between public and private events is merely a practical one. Private events play no (...) role in the experimental analysis of behavior, but they permit us to make sense of many commonplace phenomena where controlled observation is impossible but unsystematic data are available. Such interpretive exercises serve both to guide research and to displace occult explanations. (shrink)

Case studies of diverse scientific fields show how scientists use a range of resources to generate new interpretative models and to establish their plausibility as explanations of a domain. They accomplish this by manipulating imagistic representations in particular ways. I show that scientists in different domains use the same basic transformations. Common features of these transformations indicate that general cognitive strategies of interpretation, simplification, elaboration, and argumentation are at work. Social and historical studies of science emphasize the diversity of local (...) contexts of practice. However, the existence of common strategies shows that this diversity masks an important repertoire of cognitive strategies. Scientists use this repertoire to adapt their representations to meet the cognitive demands of different contexts of practice. This paper considers the implications of this finding for the notion of scientists as cognitive agents in distributed knowledge-producing systems. (shrink)

Amor Dei, “love of God” raises three questions: How do we know God is love? How do we experience love of God? How free are we to love God? This book presents three kinds of love, worldly, spiritual, and divine to understand God’s love. The work begins with Augustine’s Confessions highlighting his Manichean and Neoplatonic periods before his conversion to Christianity. Augustine’s confrontation with Pelagius anticipates the unresolved disputes concerning God’s love and free will. In the sixteenth-century the Italian humanist, (...) Gasparo Contarini introduces the notion of “divine amplitude” to demonstrate how God’s goodness is manifested in the human agent. Pierre de Bérulle, Guillaume Gibieuf, and Nicolas Malebranche show connections with Contarini in the seventeenth-century controversies relating free will and divine love. In response to the free will dispute, the Scottish philosopher, William Chalmers, offers his solution. Cornelius Jansen relentlessly asserts his anti-Pelagian interpretation of Augustine stirring up more controversy. John Norris, Malebranche’s English disciple, exchanges his views with Mary Astell and Damaris Masham. In the tradition of Cambridge Platonism, Ralph Cudworth conveys a God who “sweetly governs.” The organization of sections represents the love of God in ascending-descending movements demonstrating that, “human love is inseparable from divine love.”.

In philosophy of aesthetics, scholars commonly express a commitment to the premise that there is a distinctive type of judgment that can be meaningfully labeled “aesthetic”, and that these judgments are distinctively different from other types of judgments. We argue that, within an Aristotelian framework, there is no clear avenue for meaningfully differentiating “aesthetic” judgment from other types of judgment, and, as such, we aim to question the assumption that aesthetic judgment does in fact constitute a distinctive kind of judgment (...) that is in need of, or can be subject to, distinctive theorizing. We advance our argument primarily through demonstrating that leading contemporary accounts of aesthetic judgment do not successfully distinguish a type of judgment in that they do not tell us how making an aesthetic judgment differs substantially from judging that 2 + 3 = 5, that football is entertaining, or that today is Tuesday.

In this work David Durst explores the development of modernism in the philosophy, politics, and culture of the first German Republic between 1918 and 1933. Through a reasoned critique of various Weimar intellectual figures such as Ernst Bloch, Martin Heidegger, and Theodor Adorno, Durst offers clarity and insight into the various aesthetic postures of the interwar period. From the cultural vibrancy of the early Weimar period to the eventual decay towards fascism and Nazi rule,Weimar Modernism provides a new and (...) coherent way to examine this important era, which has often been presented in a fragmented manner.

The problem of developing a moral philosophy of medicine is explored in this essay. Among the challenges posed to this development are the general mistrust of moral philosophy and philosophy in general created by post-modernist philosophical and even anti-philosophical thinking. This reaction to philosophical systematization is usually called antifoundationalism. I distinguish different forms of antifoundationalism, showing that not all forms of their opposites, foundationalism, are alike, especially with regards to claims made about the certitude of moral thought. I conclude that (...) we are correct to mistrust absolutist principles in a moral philosophy of medicine, but can find some center within the practice of medicine itself for a moral foundation.

To achieve the goals of ethics education, students must have oportunities to develop both moral capacities (imagination, responsibility, and perseverance) and intellectual capacities (critical thinking). This article contends that service-based learning represents an important opportunity for integrative ethics education. It describes a program of leadership internships at North Central College in Naperville, Illinois, in which faculty members conduct a for-credit reflection seminar with students involved in service internships. The seminar is based upon student-written cases about ethical issues they face in (...) their work settings. (shrink)

Despite its long tradition in social psychology, we consider that Cognitive Dissonance Theory presents serious flaws concerning its methodology which question the relevance of the theory, limit breakthroughs, and hinder the evaluation of its core hypotheses. In our opinion, these issues are mainly due to operational and methodological weaknesses that have not been sufficiently addressed since the beginnings of the theory. We start by reviewing the ambiguities concerning the definition and conceptualization of the term cognitive dissonance. We then review the (...) ways it has been operationalized and we present the shortcomings of the actual paradigms. To acquire a better understanding of the theory, we advocate a stronger focus on the nature and consequences of the cognitive dissonance state itself. Next, we emphasize the actual lack of standardization, both in the ways to induce cognitive dissonance and to assess it, which impairs the comparability of the results. Last, in addition to reviewing these limits, we suggest new ways to improve the methodology and we conclude on the importance for the field of psychology to take advantage of these important challenges to go forwards.
