The purpose of this study is to examine differences in attainment of learning outcomes between students who take a class in an online format as compared to students who take a similar class in a traditional classroom setting. While on the face of it the online learners appear to attain these outcomes to a higher degree, when we control for withdrawal rates between the two groups, as well as demographic differences related to age and class standing, we see that online (...) learners no longer outperform classroom learners. We conclude that learner outcome attainment for the two delivery formats is similar for students who are more mature and/or are experienced college students. Inexperienced college freshmen, in contrast, better attain learner outcomes in a traditional classroom setting. (shrink)

How have figures of speech configured new concepts of time, space, and mind throughout history? Brian J. McVeigh answers this question in A Psychohistory of Metaphors: Envisioning Time, Space, and Self through the Centuries by exploring “meta-framing:” our ever-increasing capability to “step back” from the environment, search out its familiar features to explain the unfamiliar, and generate “as if” forms of knowledge and metaphors of location and vision. This book demonstrates how analogizing and abstracting have altered spatio-visual perceptions, expanding (...) our introspective capabilities and allowing us to adapt to changing social circumstances.

In three experiments, subjects attempted to track multiple items as they moved independently and unpredictably about a display. Performance was not impaired when the items were briefly (but completely) occluded at various times during their motion, suggesting that occlusion is taken into account when computing enduring perceptual objecthood. Unimpaired performance required the presence of accretion and deletion cues along fixed contours at the occluding boundaries. Performance was impaired when items were present on the visual field at the same times and (...) to the same degrees as in the occlusion conditions, but disappeared and reappeared in ways which did not implicate the presence of occluding surfaces (e.g. by imploding and exploding into and out of existence, instead of accreting and deleting along a fixed contour). Unimpaired performance did not require visible occluders (i.e. Michotte’s tunnel effect) or globally consistent occluder positions. We discuss implications of these results for theories of objecthood in visual attention. (shrink)

What makes an object the same persisting individual over time? Philosophers and psychologists have both grappled with this question, but from different perspectives—philosophers conceptually analyzing the criteria for object persistence, and psychologists exploring the mental mechanisms that lead us to experience the world in terms of persisting objects. It is striking that the same themes populate explorations of persistence in these two very different fields—e.g. the roles of spatiotemporal continuity, persistence through property change, and cohesion violations. Such similarities may reflect (...) an underlying connection, in that psychological mechanisms of object persistence (especially relevant parts of mid-level visual object processing) may serve to underlie the intuitions about persistence that fuel metaphysical theories. This would be a way for cognitive science to join these two disparate fields, helping to explain the possible origins and reliability of some metaphysical intuitions, and perhaps leading to philosophical progress.

The notion that visual attention can operate over visual objects in addition to spatial locations has recently received much empirical support, but there has been relatively little empirical consideration of what can count as an `object' in the ®rst place. We have investi- gated this question in the context of the multiple object tracking paradigm, in which subjects must track a number of independently and unpredictably moving identical items in a ®eld of identical distractors. What types of feature clusters can (...) be tracked in this manner? In other words, what counts as an `object' in this task? We investigated this question with a technique we call target merging: we alter tracking displays so that distinct target and distractor loca- tions appear perceptually to be parts of the same object by merging pairs of items (one target with one distractor) in various ways ± for example, by connecting item locations with a simple line segment, by drawing the convex hull of the two items, and so forth. The data show that target merging makes the tracking task far more dif®cult to varying degrees depending on exactly how the items are merged. The effect is perceptually salient, involving in some conditions a total destruction of subjects' capacity to track multiple items. These studies provide strong evidence for the object-based nature of tracking, con®rming that in some contexts attention must be allocated to objects rather than arbitrary collections of features. In addition, the results begin to reveal the types of spatially organized scene components that can be independently attended as a function of properties such as connectedness, part struc- ture, and other types of perceptual grouping. q 2001 Elsevier Science B.V.

This chapter explores a way in which visual processing may involve innate constraints and attempts to show how such processing overcomes one enduring challenge to nativism. In particular, many challenges to nativist theories in other areas of cognitive psychology have focused on the later development of such abilities, and have argued that such development is in conflict with innate origins. Innateness, in these contexts, is seen as antidevelopmental, associated instead with static processes and principles. In contrast, certain perceptual models demonstrate (...) how the very same mental processes can both be innately specified and yet develop richly in response to experience with the environment. This process is entirely unmysterious, as shown in certain formal theories of visual perception, including those that appeal to spontaneous endogenous stimulation and those based on Bayesian inference.

In cases in which many causes together bring about an effect, it is common to select some as particularly important. Philosophers since Mill have been pessimistic about analyzing this reasoning because of its variability and the multifarious causal and pragmatic details of how it works. I argue Mill was right to think these details matter but wrong that they preclude philosophical analysis of causal selection. I show that analyzing the pragmatic details of scientific debates about the important causes of the (...) Bhopal Gas Tragedy can illuminate causal reasoning about disasters and shed new light on causality and causal selection. (shrink)

Winner of the Schumpeter Prize, 2000 and Winner of the Smith Prize in Austrian Economics, 2000, this book explores how the limitations of human knowledge create both opportunities and problems in the modern economy. The growing field of evolutionary economics has developed as a result of the traditional failure of the discipline to explain certain phenomena that impact greatly on the economy. These are: *_Evolution_ - the impact on the economy of natural change over time *_Institutions_ - the impact on (...) the economy of government and/or company policy, rules and regulations *_Knowledge_ - the impact on the economy that is felt when new information becomes available _Knowledge, Institutions and Evolution in Economics _is a punchy overview of these topics and one that has become regarded as something of a modern classic that no serious social sciences academic or student should be without.

Trading on non-public material information is fertile ground for a discussion of ethical behavior. The long-running legal tug-of-war over what constitutes illegal insider trading delivers challenges to regulatory authorities charged with detecting and enforcing the law, and is likely one of the reasons that prosecution of insider trading events remains rather uncommon. One can observe both increased volume in the equity and option markets and run-ups in the stock price prior to the announcement of the acquisitions; however, the detection of (...) illegal or unethical insider trading can be difficult. Given the legal uncertainty around insider trading and the circumstantial evidence from the trading activity, it is almost impossible to identify unethical insider trades unless there is a whistleblower or trades are large in size and impeccable in timing. Using call option trading around two merger announcements with similar firms that resulted in different ultimate treatment from the SEC, we illustrate the struggle regulators and prosecutors have with identifying and enforcing unethical insider trades.

Circumcision of males represents a surgical “vaccine“ against a wide variety of infections, adverse medical conditions and potentially fatal diseases over their lifetime, and also protects their sexual partners. In experienced hands, this common, inexpensive procedure is very safe, can be pain‐free and can be performed at any age. The benefits vastly outweigh risks. The enormous public health benefits include protection from urinary tract infections, sexually transmitted HIV, HPV, syphilis and chancroid, penile and prostate cancer, phimosis, thrush, and inflammatory dermatoses. (...) In women circumcision of the male partner provides substantial protection from cervical cancer and chlamydia. Circumcision has socio‐sexual benefits and reduces sexual problems with age. It has no adverse effect on penile sensitivity, function, or sensation during sexual arousal. Most women prefer the circumcised penis for appearance, hygiene and sex. Given the convincing epidemiological evidence and biological support, routine circumcision should be highly recommended by all health professionals.

The foundational principles of representative democracy are under attack globally. What we desperately need are enlightened and persuasive public intellectuals who can help us see through the fog of our fear, anger, and disillusionment, to find our rational political commitments again. One of these public intellectuals is undoubtedly Yuval Noah Harari, the bestselling author of three recent books – Sapiens, Homo Deus, and 21 Lessons for the 21st Century. Harari is also a frequent contributor in the popular press, and a (...) guest on shows, podcasts, panels, and as a keynote speaker. Add to all this that Harari is acting on his lofty academic ideals through ‘Sapienship’, a multidisciplinary organization he cofounded that advocates for global responsibility, clarifies the global conversation, and focuses attention on the most important global challenges. I single out Harari because I presume many readers will be familiar with his work. He is certainly one of the fastest rising stars of public intellectualism. Unfortunately, his work is undercut by the philosophical positions he put forth in his first bestselling book, Sapiens. In this review/critique I wish to show that in order for Harari advance a coherent political or ideological argument, he must first shore up his philosophical commitments. (shrink)

Scholars working in philosophy of action still struggle with the freedom/determinism dichotomy that stretches back to Hellenist philosophy and the metaphysics that gave rise to it. Although that metaphysics has been repudiated in current philosophy of mind and cognitive science, the dichotomy still haunts these fields. As such, action is understood as distinct from movement, or motion. In early China, under a very different metaphysical paradigm, no such distinction is made. Instead, a notion of self-caused movement, or spontaneity, is elaborated. (...) In this article a general conception of spontaneity from early Daoism is explained, detailing its constituent aspects. Similar notions appeared from time to time in Western philosophy, and these instances are pursued, exploring how their instantiations differed from Daoist spontaneity and why. Based on these approximate examples of spontaneity and on early Daoist spontaneity, new criteria are postulated for a plausible theory of action that dispenses with presuppositions that eventuate in a freedom/determinism dichotomy, and instead the possibility is offered of a general model of action that can be applied smoothly across current philosophical and cognitive scientific subdisciplines.

The relations of comparison and contrast among the viewpoints of characters and between the viewpoints of authors and characters is one of the most important dimensions of meaning in literary texts.... It is for this reason that the analysis of irony, as a central tonal medium for registering differences in point of view, occupies a position of singular importance in the interpretation of literary meaning.Irony stings. Among friends it might be playful, its target joining in the fun. But it is (...) hard to see irony figuring into any how-to guide for making friends in the first place. Indeed, the word is absent from Dale Carnegie's How to Win Friends and Influence People. More often irony is divisive, driving a wedge... (shrink)

This article describes the development and validation of a diagnostic test of German and its integration in a programme of formative assessment during a one-year initial teacher-training course. The test focuses on linguistic aspects that cause difficulty for trainee teachers of German as a foreign language and assesses implicit and explicit grammatical knowledge as well as students' confidence in this knowledge. Administration of the test to 57 German speakers in four groups (first-year undergraduates, fourth-year undergraduates, postgraduate trainees, and native speakers) (...) provided evidence of its reliability and validity.

Many professional philosophers are hesitant about “public philosophy”—unsure about what it is and how it’s done, and downright pessimistic about whether it is an important and valuable philosophical practice. In response to this hesitancy and in support of public philosophy, I argue that most of these philosophers already find at least one form of public philosophy important and valuable for the discipline and profession: teaching. I offer and defend a broad conception of public philosophy in order support this controversial claim. (...) I continue by briefly offering some reasons to think that public philosophy is of value for society generally (i.e., “the public”), and argue that we, as a profession, need to fully recognize our standing commitment to public-facing philosophical work; and to engage in serious discussion and debate to better examine the various types of public philosophy, clarify the broad range of public-facing activities, and encourage/reward further public work of value.

The aim of this essay is to give a high-level overview of Irenaeus’s beatific vision, and to suggest that for him, the beatific vision has a temporal dimension (now and future) and a dimension of degree (lesser now, greater in the future). His beatific vision is witnessed as it intersects with at least four main ideas in his writing—the Trinity, anthropology, resurrection, and his eschatology. Irenaeus famously held that ‘the glory of God is living man, and the life of man (...) is the vision of God’ (AH 4.20.7), which speaks to the reality of seeing God in the present, but he could also look forward in anticipation to beholding the face of God in the resurrected body in the new creation. What made the latter possible is the gradual beholding of God in the present that makes one prepared to see God’s glory in the future. Additionally, the visio Dei is Trinitarian. We behold God in Christ, since God the Father is invisible, and it is the Holy Spirit who prepares us incrementally to see God. (shrink)

Some of the evidence for a “magical number 4” has come from the study of visual cognition, and Cowan reinterprets such evidence in terms of a single general limit on memory and attention. We evaluate this evidence, including some studies not mentioned by Cowan, and argue that limitations in visual processing are distinct from those involved in other memory phenomena.

This paper takes a unique approach to framing the political obligation social media companies like Twitter and Facebook have in a democratic society by casting the public sphere as a common-pool resource. Over the last decade or so much of our civic discourse has moved to social media platforms such as Facebook and Twitter. This paper argues that just as citizens have an obligation to one another, social media companies have an obligation to promote agonistic forms of civic, political discourse (...) through their algorithms. This algorithmic obligation that social media companies have must be reconciled with social media companies’ formulation of their fiduciary shareholder obligations. We posit that a commons based view of social media discourse allows these companies to make both a democratic health and fiduciary interest argument. (shrink)

We suggest that the sensorimotor “theory” of vision is really an unstructured collection of separate ideas, and that much of the evidence cited in its favor at best supports only a subset of these ideas. As an example, we note that work on change blindness does not “vindicate” (or even speak to) much of the sensorimotor framework. Moreover, the ideas themselves are not always internally consistent. Finally, the proposed framework draws on ideas initially espoused by James Gibson, but does little (...) to differentiate itself from those earlier views. For even part of this framework to become testable, it must specify which sources of evidence can support or contradict each of the component hypotheses. (shrink)

Is innate cognitive modularity consistent with a lack of innate neural modularity? Quartz & Sejnowski's implicit negative answer to his question fuels their antinativist and antimodular cognitive conclusions.

Recent evidence suggests that performance on reasoning tasks may reflect the operation of a number of distinct cognitive mechanisms and processes. This paper explores the implications of this view of the mind for the descriptive and normative assessment of reasoning. I suggest that descriptive questions such as “Are we equipped to reason using rule X?” and normative questions such as “Are we rational?” are obsolete—they do not possess a fine enough grain of architectural resolution to accurately characterize the mind. I (...) explore how this general lesson can apply to specific experimental interpretations, and suggest that 'rationality' must be evaluated along a number of importantly distinct dimensions.

A debate over whether God predestines some to reprobation broke out in the ninth century. No one actually taught this view, but both John Scotus Eriugena and Hincmar of Rheims, among other churchmen at the time, presumed it to be the view of those who referred to themselves as “double predestinarians.” In part, this was because the double predestinarians had made much of Augustine’s phrase “predestined to punishment,” a phrase that can in fact be found in several of his writings. (...) This article, which is the second of two parts, argues that Eriugena and Hincmar had difficulty avoiding the appearance of disagreeing entirely with Augustine’s use of that phrase. Eriugena said the phrase is to be understood a contrario to the divine nature; Hincmar said it is to be understood in a generic sense about God’s judgment on sin. Of the two, Hincmar came the closest to acknowledging that Augustine might have erred in using the phrase as he did. (shrink)

I argue that José Luis Bermúdez has not shown that there is a paradox in our concept of self-consciousness. The deflationary theory is not a plausible theory of self-consciousness, so its paradoxicality is irrelevant. A more plausible theory, 'the simple theory', is not paradoxical. However, I do think there is a puzzle about the connection between self-consciousness and 'I'-thoughts.

A debate over whether God predestines to make some people reprobate broke out in the ninth century. No one taught this view, but it was presumed by several churchmen at the time to be the position of those who called themselves double predestinarians. In part, this article explains why two double predestinarians, Gottschalk of Orbais and Ratramnus of Corbie, were mistaken for proponents of this view. They had been trying to explain Augustine’s phrase, “those predestined to punishment”, which they found (...) in no fewer than ten of Augustine’s texts. Gottschalk points out Augustine used the phrase interchangeably with the term reprobate. Thus, to Gottschalk, it is not a statement about what God predestines; rather, it is a statement about the effect of predestination on certain people. Likewise, to Ratramnus, the phrase referred to the effect of God’s ordering of both the good and evil acts of persons. That Gottschalk and Ratramnus identified Augustine’s use of the phrase with a belief in double predestination was due to their reading Augustine through the lens of Isidore of Seville’s Sententiae II.6.

Prior to its publication, Gary Cox's MakingVotesCount was widely and eagerly anticipated. (Indeed, some years ago, I received a referee report dismissing my submission as unnecessary because superior analysis would eventually appear in Cox's then forthcoming manuscript.) Upon its release in 1998, the book was instantly lauded: it collected multiple awards, including the prestigious Woodrow Wilson prize for best book published on government, politics, or international affairs. This acclaim was scarcely surprising – Cox has been one of the foremost scholars (...) of elections and legislatures for the whole of his professional career. He is responsible for an impressive body of work spanning multiple research topics, nations, and methods of analysis. This book is testimony to his breadth, as it catalogs the key electoral features of virtually the whole set of modern democracies (more than 70), and makes frequent forays into diverse nations in search of empirical support for novel theoretical findings. In brief, Cox's project is to bring together a large formal, deductive literature on voting rules and social choice with an equally voluminous empirical, inductive literature on elections and party systems in the world's democracies. The prizes it garnered are one measure of the book's success at this merger; a large boost in Cox's swelling citation count will doubtless follow, reiterating the judgement that this is the major work on electoral law and voting to date.
