We address two major limitations of Schyns et al. First, we clarify their concept of “features” by postulating several levels for processing. The composition of the feature set at each level determines the set at the next higher level, following simple structural guidelines. Second, we show that our proposed framework reconciles feature-creation and fixed-feature approaches.

The practices of economists increase experimental reproducibility relative to those of selected psychologists but should not be universally adopted. Procedures criticized by Hertwig and Ortmann as producing variable data are valuable, instead, for generating questions. The procedure of choice should depend on the theoretical goal: measure a known factor or learn what factors are important and need to be measured.

Palmer describes a “subjective barrier” that limits knowledge of others' experience. We discuss how this barrier extends to all knowledge, becoming less distinct as theoretical constructs are strengthened. We provide evidence for isomorphic experience, among individuals with similar physiologies, by showing that perceived relations between colors are as similar when viewing pigments as when viewing subjective colors caused by flickering bars.

Neuromarketing is an emerging field in which academic and industry research scientists employ neuroscience techniques to study marketing practices and consumer behavior. The use of neuroscience techniques, it is argued, facilitates a more direct understanding of how brain states and other physiological mechanisms are related to consumer behavior and decision making. Herein, we will articulate common ethical concerns with neuromarketing as currently practiced, focusing on the potential risks to consumers and the ethical decisions faced by companies. We argue that the (...) most frequently raised concerns—threats to consumer autonomy, privacy, and control—do not rise to meaningful ethical issues given the current capabilities and implementation of neuromarketing research. But, we identify how potentially serious ethical issues may emerge from neuromarketing research practices in industry, which are largely proprietary and opaque. We identify steps that can mitigate associated ethical risks and thus reduce the threats to consumers. We conclude that neuromarketing has clear potential for positive impact on society and consumers, a fact rarely considered in the discussion on the ethics of neuromarketing. (shrink)

The phenomenon of ambiguity aversion, in which risky gambles with known probabilities are preferred over ambiguous gambles with unknown probabilities, has been thoroughly documented in adults but never measured in children. Here, we use two distinct tasks to investigate ambiguity preferences of children (8- to 9-year-olds) and a comparison group of adults (19- to 27-year-olds). Across three separate measures, we found evidence for significant ambiguity aversion in adults but not in children and for greater ambiguity aversion in adults compared to (...) children. As ambiguity aversion in adults has been theorized to result from a preference to bet on the known and avoid the unfamiliar, we separately measured familiarity bias and found that children, like adults, are biased towards the familiar. Our findings indicate that ambiguity aversion emerges across the course of development between childhood and adolescence, while a familiarity bias is already present in childhood. (shrink)

B&H understate the difficulties facing their version of color realism. We doubt that they can fix reflectance types and magnitudes in a way that does not invoke relations to perceivers. B&HÂ’s account therefore resembles the dispositional or ecological accounts that they dismiss. This is a good thing, for a dispositional account is promising if understood in an ecological framework.

This chapter discusses the roles of ether and electrons in relativity theory. One of the most radical moves made by Albert Einstein was to dismiss the ether from electrodynamics. His fellow physicists felt challenged by Einstein’s view, and they came up with a variety of responses, ranging from enthusiastic approval, to dismissive rejection. Among the naysayers were the electron theorists, who were unanimous in their affirmation of the ether, even if they agreed with other aspects of Einstein’s theory of relativity. (...) The eventual success of the latter theory (circa 1911) owed much to Hermann Minkowski’s idea of four-dimensional spacetime, which was portrayed as a conceptual substitute of sorts for the ether.

The law of gravitational attraction is a window on three formal approaches to laws of nature based on Lorentz-invariance: Poincaré’s four-dimensional vector space (1906), Minkowski’s matrix calculus and spacetime geometry (1908), and Sommerfeld’s 4-vector algebra (1910). In virtue of a common appeal to 4-vectors for the characterization of gravitational attraction, these three contributions track the emergence and early development of four-dimensional physics.

Albert Einstein’s bold assertion of the form invariance of the equation of a spherical light wave with respect to inertial frames of reference became, in the space of 6 years, the preferred foundation of his theory of relativity. Early on, however, Einstein’s universal light-sphere invariance was challenged on epistemological grounds by Henri Poincaré, who promoted an alternative demonstration of the foundations of relativity theory based on the notion of a light ellipsoid. A third figure of light, Hermann Minkowski’s lightcone also (...) provided a new means of envisioning the foundations of relativity. Drawing in part on archival sources, this paper shows how an informal, international group of physicists, mathematicians, and engineers, including Einstein, Paul Langevin, Poincaré, Hermann Minkowski, Ebenezer Cunningham, Harry Bateman, Otto Berg, Max Planck, Max von Laue, A. A. Robb, and Ludwig Silberstein, employed figures of light during the formative years of relativity theory in their discovery of the salient features of the relativistic worldview. (shrink)

This letter corrects errors of fact contained in a review by Yves Gingras of a biopic about Henri Poincaré.

The reception of Poincaré’s conventionalist doctrine of space by mathematicians is studied for the period 1891–1911. The opposing view of Riemann and Helmholtz, according to which the geometry of space is an empirical question, is shown to have swayed several geometers. This preference is considered in the context of changing views of the nature of space in theoretical physics, and with respect to structural and social changes within mathematics. Included in the latter evolution is the emergence of non-Euclidean geometry as (...) a new sub-discipline. (shrink)

A plausible explanation of the wrongfulness of threatening, advanced most explicitly by Mitchell Berman, is that the wrongfulness of threatening derives from the wrongfulness of the act threatened. This essay argues that this explanation is inadequate. We can learn something important about the wrongfulness of threatening (with implications for thinking about coercion) by comparing credible threats to some other claims of impending harm. A credible bluff threat to do harm is likely to be more and differently wrongful than making intentionally (...) false warnings about other sources of harm. This essay surveys some examples to secure this point, shows that Berman's moralized account of their wrongfulness is wanting, and offers the outline of an approach better suited to explain the wrongfulness of threatening.1.

Academic dishonesty is a persistent problem in the American educational system. The present investigation examined how reports of academic cheating related to students' emphasis on their moral identities and their sensitivity to social evaluation. Seventy college students at a large southeastern university completed a battery of surveys. Symptoms of social anxiety were positively correlated with recall of academic cheating. Additionally, relative to students who placed less importance on their moral identities, students who placed more importance on their moral identities recalled (...) significantly fewer instances of cheating. In summary, these findings suggest that students are less likely to cheat on their school work when they place greater emphasis on their moral identity and are less sensitive to social evaluation. Practical interventions to rampant cheating in American schools are discussed. (shrink)

Traditional theists believe that there exists an all-knowing, all-powerful, perfectly loving, and perfectly good God. They also believe that God created the world, sustains it in being from moment to moment, and providentially guides all events, in accordance with a plan, towards a good ending. Historically, most traditional theists have believed that God sometimes answers prayers for particular things. In keeping with the literature on this subject, these prayers are referred to as ‘petitionary prayers’. This article discusses several problems related (...) to the concept of the traditional theistic God's answering petitionary prayers. (shrink)

This volume explores the philosophical issues involved in the idea of petitionary prayer, where this is conceived as an activity designed to influence the action of the all-knowing, all-powerful, perfectly good God of traditional theism. Theists have always recognized various logical and moral limits to divine action in the world, but do these limits leave any space among God's reasons for petitionary prayer to make a difference? Petitionary Prayer: A Philosophical Investigation develops a new account of the conditions required for (...) a petitionary prayer to be answered by employing the notion of contrastive explanation. With careful attention to recent developments in metaphysics, epistemology, and value theory, Scott A. Davison surveys the contemporary literature on this question. He considers questions about human freedom and responsibility in relation to different views of divine providence, along with the puzzles inherent in Christian teachings concerning petitionary prayer. Davison develops new challenges to the coherence of the idea of answered petitionary prayer based upon the nature of divine freedom, the limits of human knowledge, and the nature of those good things that require a recipient's permission before they can be given. He proposes new defences, building upon careful analysis of the shortcomings of previous proposals and clarifying the issues for future debate. (shrink)

Recent scholarship in business ethics has revealed the importance of privacy expectations as they relate to implicit privacy norms and the business practices that may violate these expectations. Yet, it is unclear how and when businesses may violate these expectations, factors that form or influence privacy expectations, or whether or not expectations have in fact been violated by company actions. This article reports the findings of three studies exploring how and when the corporate dissemination of consumer data violates privacy expectations. (...) The results indicate that consumer sentiment is more negative following intentional releases of sensitive consumer data, but the effect of data dissemination is more complex than that of company intentionality and data sensitivity alone. Companies can effectively set, and re-affirm, privacy expectations via consent procedures preceding and succeeding data dissemination notifications. Although implied consent has become more widely used in practice, we show how explicit consent outperforms implied consent in these regards. Importantly, this research provides process evidence that identifies perceived violation of privacy expectations as the underlying mechanism to explain the deleterious effects, on consumer sentiment, when company actions are misaligned with consumers’ privacy expectations. Ethical implications for companies collecting and disseminating consumer information are offered. (shrink)

The consideration of ‘mutual benefits’ and partner cooperation have long been the accepted standpoint from which to draw inference about the onset, maintenance and breakdown of the coral‐algae endosymbiosis. In this paper, I review recent research into the climate‐induced breakdown of this important symbiosis (namely ‘coral bleaching’) that challenges the validity of this long‐standing belief. Indeed, I introduce a more parsimonious explanation, in which the coral host exerts a ‘controlled parasitism’ over its algal symbionts that is akin to an enforced (...) domestication arrangement. Far from being pathogenic, a range of well‐established cellular processes are reviewed that support the role of the coral host as an active ‘farmer’ of the energy‐rich photoassimilates from its captive symbionts. Importantly, this new paradigm reposes the deleterious bleaching response in terms of an envelope of environmental conditions in which the exploitative and captive measures of the coral host are severely restricted. The ramification of this new paradigm for developing management strategies that may assist the evolution of bleaching resistance in corals is discussed. (shrink)

In ‘Two Notions of Being: Entity and Essence’ E. J. Lowe defends “serious essentialism”. Serious essentialism is the position that everything has an essence, essences are not themselves things, and essences are the ground for metaphysical necessity and possibility. Lowe's defence of serious essentialism is both metaphysical and epistemological. In what follows I use Lowe's discussion as a point of departure for, first, adding some considerations for the plausibility of essentialism and, second, some work on modal epistemology.

What sorts of things are there in the world? Clearly enough, there are concrete, material things; but are there other things too, perhaps nonconcrete or non-material things? Some people believe that there are such things, which are often called abstract ; purported examples of such objects include numbers, properties, possible but non-actual states of affairs, propositions, and sets. Following a long-standing tradition, I shall describe persons who believe that there are abstract objects as ‘platonists’. In this paper, I shall not (...) directly address the plausibility of platonism, as compared with its rivals; instead, I shall confine my attention to one way in which some people have tried to combine platonism and theism. More specifically, I shall concentrate upon the claim that abstract objects depend upon God ontologically ; I shall argue that platonistic theists should reject DEP in favour of the claim that abstract objects exist independently of God . In order to evaluate the relative merits of DEP versus IND, it will be helpful to examine in some detail a particular articulation of DEP. When it comes to recent work on DEP, we can do no better in this regard than to examine the recent work of Thomas V. Morris and Christopher H. Menzel. According Morris and Menzel, there is a sense in which God literally creates such abstracta through engaging in intellective activities. (shrink)

I argue that a well-known argument concerning moral luck supports something like the Principle of Alternate Possibilities (PAP), despite the attacks on PAP by Harry Frankfurt and John Martin Fischer.

Many recent theories of coercion broaden the scope of the concept coercion by encompassing interactions in which one agent pressures another to act, subject to some further qualifications. I have argued previously that this way of conceptualizing coercion undermines its suitability for theoretical use in politics and ethics. I have also explicated a narrower, more traditional approach—“the enforcement approach to coercion”—and argued for its superiority. In this essay, I consider the prospects for broadening this more traditional approach to cover some (...) cases that don’t seem to fit this approach, but nonetheless seem coercive, such as the demands routinely made on people by credit card companies, demands on students by higher educational institutions, and demands made by European financial institutions on the government of Greece. I analyze the similarities and differences of these compared to more central cases of coercion, discussing what lessons can be drawn from this analysis. (shrink)

I respond to Daniel and Frances Howard-Snyder’s criticisms of my arguments in another place for the conclusion that human supplicants would have little responsibility (if any) for the result of answered petitionary prayer, and criticize their defense of the claim that God would have good reasons for creating an institution of petitionary prayer.

In this paper, I explore several privacy issues as they arise with respect to the divine/human relationship. First, in section 1, I discuss the notion of privacy in a general way. Section 2 is devoted to the claim that privacy involves control over information about oneself. In section 3, I summarize the arguments offered recently by Margaret Falls-Corbitt and F. Michael McLain for the conclusion that God respects the privacy of human persons by refraining from knowing certain things about them. (...) Finally, in section 4, I shall criticize Falls-Corbitt and McLain’s arguments and make some concluding remarks about God and privacy. (shrink)

Studies using Posner’s spatial cueing paradigm have demonstrated that participants can allocate their attention to specific target locations based on the predictiveness of preceding cues. Four experiments were conducted to investigate attentional orienting processes operating in a high probability condition as compared to a low probability condition using various types of centrally-presented cues. Spatially-informative cues resulted in cueing effects for both probability conditions, with significantly larger CEs in the high probability conditions than the low probability conditions. Participants in the high (...) probability conditions reported little or no awareness of cue–target probabilities after task completion. Our results provide support for an implicit learning account of the proportion valid effect under experimental conditions involving spatially-informative central cues and relatively short stimulus onset asynchronies.

This essay provides a positive account of coercion that avoids significant difficulties that have confronted most other recent accounts. It enters this territory by noting a dispute over whether coercion has to manipulate the will of the coercee, or whether direct force inhibiting action (such as manhandling or imprisoning) is itself coercive. Though this dispute may at first seem a mere matter of taxonomic categorization, I argue that this dispute reflects an important divergence in thought about the nature of coercion. (...) Though it has rarely been noted, there are two significantly different ways of theorizing coercion found in recent writing on coercion. One focuses on the ability of the coercer to inhibit actions by the coercee through techniques such as force, violence, and like powers, or threats based in such powers. The other approach restricts coercion to cases where coercion manipulates the will of the coercee, though widens it to include any sort of threat that puts pressure on the coercee's will and alters the coercee's intentional choice of action. The former, enforcement approach used to be widely assumed by many political theorists who discussed the place of coercion in law and politics, though it has been largely supplanted by the latter, pressure approach. I show that these approaches are indeed quite distinct, and argue that the enforcement approach is in several ways superior to and more fundamental than the pressure approach for recognizing and understanding coercion in ethics and political and legal philosophy. I also consider and respond to a number of objections to the enforcement approach, showing that it can deal with some puzzle cases such as bluffs, blackmail, inefficacious threats, oblique threats, and economic coercion.

In this paper I challenge the notion that a healthy and resilient coral is (in all cases) a fast‐growing coral, and by inference, that a reef characterised by a fast trajectory toward high coral cover is necessarily a healthy and resilient reef. Instead, I explain how emerging evidence links fast skeletal extension rates with elevated coral‐algae (symbiotic) respiration rates, most‐often mediated by nutrient‐enlarged symbiont populations and/or rising sea temperatures. Elevated respiration rates can act to reduce the autotrophic capacity (photosynthesis:respiration ratio) (...) of the symbiosis. This restricts the capacity of the coral host to build and maintain sufficient energy reserves (e.g. lipids) needed to sustain essential homeostatic functions, including sexual reproduction and biophysical stress resistance. Moreover, it explains the somewhat paradoxical scenario, whereby at the ecological instant before the reef‐building capacity of the symbiosis is lost, a reef can look visually at its best and be accreting CaCO3 at its maximum.

This essay differentiates two approaches to understanding the concept of coercion, and argues for the relative merits of the one currently out of fashion. The approach currently dominant in the philosophical literature treats threats as essential to coercion, and understands coercion in terms of the way threats alter the costs and benefits of an agent’s actions; I call this the “pressure” approach. It has largely superseded the “enforcement approach,” which focuses on the powers and actions of the coercer rather than (...) the perspective of the coercee. The enforcement approach identifies coercion with certain uses of the kinds of powers that agents need to accumulate and wield in order to be able to make significant, credible threats. Though there is considerable overlap extensionally in the instances of coercion recognized by the two approaches, the enforcement approach encompasses some uses of power to coerce that do not involve threats . It also circumscribes which threats should be counted as coercive, though notably it provides a picture of coercion that is non-moralized in its essentials. While there may be specific purposes for which a pressure account is to be preferred, I argue that the enforcement approach better describes how coercion works, and elucidates factors that are often tacitly assumed by pressure accounts. It also is more useful for explaining the social and political significance of coercion, and why coercion is thought to have the implications commonly associated with it. In particular, I argue that it helps us understand why uses of coercion are in general a matter of ethical significance, why state authority depends on commanding a monopoly on the right to use coercion, and why being coerced may reasonably provide one a defense against being held responsible for actions one is coerced into taking.

From the perspective of nonlinear science, it is argued that one may accept physicalism and reject substance dualism without being forced into reductionism. This permits a property dualism under which biological and mental phenomena may emerge from intricate positive feedback networks, involving many levels of both the biological and cognitive hierarchies.
