We investigate the causal uncertainty surrounding the flash crash in the U.S. Treasury bond market on October 15, 2014, and the unresolved concern that no clear link has been identified between the start of the flash crash at 9:33 and the opening of the U.S. equity market at 9:30. We consider the contributory effect of mini flash crashes in equity markets, and find that the number of equity mini flash crashes in the three-minute window between market open and the Treasury (...) Flash Crash was 2.6 times larger than the number experienced in any other three-minute window in the prior ten weekdays. We argue that (a) this statistically significant finding suggests that mini flash crashes in equity markets both predicted and contributed to the October 2014 U.S. Treasury Bond Flash Crash, and (b) mini-flash crashes are important phenomena with negative externalities that deserve much greater scholarly attention.

Designer Biology: The Ethics of Intensively Engineering Biological and Ecological Systems consists of thirteen chapters that address the ethical issues raised by technological intervention and design across a broad range of biological and ecological systems. Among the technologies addressed are geoengineering, human enhancement, sex selection, genetic modification, and synthetic biology.

Introduction: -/- It is likely that Boethius (480-524ce) inaugurates, in Latin Christian theology, the consideration of personhood as such. In the Treatise Against Eutyches and Nestorius Boethius gives a well-known definition of personhood according to genus and difference(s): a person is an individual substance of a rational nature. Personhood is predicated only of individual rational substances. This chapter situates Boethius in relation to significant Christian theologians before and after him, and the way in which his definition of personhood is a (...) particular answer to the question, “Jesus has two natures, a divine nature and a human nature, but is one what?” Among Greek (and Syriac) speaking theologians, the typical answer is that Jesus is one ‘hypostasis’. Among Latin speaking theologians, the typical answer is that Jesus is one ‘persona’. It is Boethius’s definition of ‘persona’ that inaugurates personhood as such in Latin speaking theology. Although the Greek and Syriac theologians that I survey come close to a concept of personhood as a distinct category, they do not have such a concept and did not need it for their theological purposes. I show that Rusticus the Deacon is an early witness to this Latin theological invention, and also show that for later Latin theologians, the rationality condition for personhood does very little metaphysical work for their Trinitarian theology or Christology. -/- Further, this chapter surveys Patristic and Medieval Christian theologians’ answers to the question, “God the Father, God the Son, and God the Holy Spirit are one God, but each is one what?” The same replies as above are typically given by Christian theologians. These two theological questions frame the discussion about personhood (and ‘hypostasis’) and put a boundary around what a satisfying account of personhood (and ‘hypostasis’) would be. -/- In contemporary philosophy, there is a lot of attention paid to the rationality condition for personhood. But if we look at the text in which Boethius defines a person, we do not find any precise criteria for it. In other texts, he says that a rational being is one compatible with (capable of) thought and free choice of the will. What we find is that detailed discussion of personhood shows up in theological questions about the Trinity and Incarnation, but not in e.g., applied ethics. The intrusion of personhood into contemporary applied ethics with a focus on detailed and disputed criteria for rationality as a condition for personhood seems to be a modern development. From a Patristic and Medieval Christian theology point of view, trying to find just the right detailed criteria for rationality in order to define personhood is a wild goose chase. This chapter makes clear another contribution that Christian theology had for personhood. Given the theological issues at play in developing a notion of personhood, Christian theologians came to posit that e.g., an individual human is a person contingently (i.e. not essentially), but God the Father, God the Son, and God the Holy Spirit are each a person essentially. The contingency for created persons is not based on whether e.g., an individual human has conscious acts (as might be the case for John Locke) but on the possibility of a divine person’s assuming e.g., an individual human nature. -/- This sampling of Christian intellectual history spans over one thousand years. I make no claim of being exhaustive. The chapter consists of six sections, where each section covers significant historical conversation partners who together represent the sorts of things that Patristic and Medieval Christian theologians where concerned with in theorizing about ‘persona’ or ‘hypostasis’. -/- 1. Origen of Alexandria and the Cappadocians: Basil of Caesarea and Gregory of Nyssa 2. Miaphysites: Severus of Antioch, John Philoponus, and Peter of Callinicum 3. Boethius and Rusticus the Deacon: Rationality, Subsistence, and the Invention of Personhood 4. Neo-Chalcedonians (II): Leontius of Byzantium 5. Scholastic Neo-Chalcedonians (I): Gilbert of Poitiers, Richard of St. Victor, William of Auxerre, Alexander of Hales, Bonaventure, Thomas Aquinas, and William of Ware 6.

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.

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)

A computational modeling approach was used to test one possible explanation for the limited capacity of the subitizing phenomenon. Most existing models of this phenomenon associate the subitizing span with an assumed structural limitation of the human information processing system. In contrast, we show how this limit might emerge as the combinatorics of the space of enumeration problems interacts with the human cognitive architecture in the context of an enumeration task. Subitizing‐like behavior was generated in two different models of enumeration, (...) one based on the ACT‐R cognitive architecture and the other based on the principles of parallel distributed processing (PDP). Our results provide good qualitative fits to results obtained in a variety of empirical studies. (shrink)

American football is played in a chaotic visual environment filled with relevant and distracting information. We investigated the hypothesis that collegiate football players show exceptional skill at shielding their response execution from the interfering effects of distraction ( interference control ). The performances of 280 football players from National Collegiate Athletic Association Division I football programs were compared to age-matched controls in a variant of the Eriksen flanker task ( Eriksen and Eriksen, 1974 ). This task quantifies the magnitude of (...) interference produced by visual distraction on split-second response execution. Overall, football athletes and age controls showed similar mean reaction times (RTs) and accuracy rates. However, football athletes were more proficient at shielding their response execution speed from the interfering effects of distraction (i.e., smaller flanker effect costs on RT). Offensive and defensive players showed smaller interference costs compared to controls, but defensive players showed the smallest costs. All defensive positions and one offensive position showed statistically smaller interference effects when compared directly to age controls. These data reveal a clear cognitive advantage among football athletes at executing motor responses in the face of distraction, the existence and magnitude of which vary by position. Individual differences in cognitive control may have important implications for both player selection and development to improve interference control capabilities during play. (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 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.

Research programmes are sets of problems preferred on epistemic grounds and including preferred heuristics for inquiry. Charles Lyell's research programme for biogeograpy includes the problem of explaining the distribution of species constrained by laws governing locomotion and containment of species. Included in the programme are laws governing the supernatural introduction of replacement species. Wallace and Darwin derected arguments against the putative intelligibility of this aspect of Lyell's programme before discovering natural selection, and their defence, at this time of natural laws (...) governing the introduction of new species is interesting as a defence of a noval programme of research, not a defence of a proposed theroy. These arguments are presented and an epistemological foundation is offered for them. 1 The author is indebted to a referee for helpful comments on an earlier draft of this paper. (shrink)

The data in this special issue are both encouraging and discouraging. On the positive side, researchers are making theoretical breakthroughs into the psychology of the academic cheater, which may result in practical interventions. Yet the studies illustrate the sheer magnitude of the problem and the resources needed to address unethical behavior among the younger members of the American academe. In short, this special issue shows that the "Internet revolution" facilitates new types of academic dishonesty (Sisti, this issue; Stephens, Young, & (...) Calabrese, this issue); that academic cheating is often an intentional, planned act that results from a Machiavellian tendency to neutralize moral sanctions against cheating (Harding, Mayhew, Finelli, & Carpenter, this issue); that motivations to cheat differ across students (Davy, Kincaid, Smith, & Trawick, this issue; Wowra, this issue); and that academic cheating is a symptom of a larger problem (Lovett-Hooper, Komarraju, Weston, & Dollinger, this issue; Wowra, this issue).

Ethical sensitivity triggers the entire ethical decision-making process (i.e., recognition of ethical content in work situations). In this article, five factors are examined that affect tax practitioners' professional ethical sensitivity. The five factors that were examined include role conflict, role ambiguity, job satisfaction, professional commitment, and ethical orientation. Ethical content in work situations is examined in relation to professional ethics as enumerated by the American Institute of Certified Public Accountant's (AICPA) Statements on Responsibilities in Tax Practice (SRTP). Utilizing Hunt and (...) Vitell's (1986, 1993) General Theory of Ethics, a model of ethical sensitivity was constructed and empirically tested. Role conflict negatively and job satisfaction positively influenced tax practitioners' ethical sensitivity. Also, the covariates of the tax practitioner's professional risk level and type of employer were found to be significant. The significant factors are job specific. The tax firm may have the best opportunity to positively change a tax practitioner's ethical recognition abilities. Professional accounting organizations may need to evaluate if resources should be used to formulate, maintain, and publicize codes of conduct because of the lack of significance of professional commitment.

Heterogeneity within MDD has hampered identification of biological markers (e.g., intermediate phenotypes, IPs) that might increase risk for the disorder or reflect closer links to the genes underlying the disease process. The newer characterizations of dimensions of MDD within Research Domain Criteria (RDoC) domains may align well with the goal of defining IPs. We compare a sample of 25 individuals with MDD compared to 29 age and education matched controls in multimodal assessment. The multimodal RDoC assessment included the primary IP (...) biomarker, positron emission tomography (PET) with a selective radiotracer for 5-HT1A ([11C]WAY-100635), as well as event-related functional MRI with a Go/No-go task targeting the Cognitive Control network, neuropsychological assessment of affective perception, negative memory bias and Cognitive Control domains. There was also an exploratory genetic analysis with the serotonin transporter (5-HTTLPR) and monamine oxidase A (MAO-A) genes. In regression analyses, lower 5-HT1A binding potential (BP) in the MDD group was related to diminished engagement of the Cognitive Control network, slowed resolution of interfering cognitive stimuli, one element of Cognitive Control. In contrast, higher/normative levels of 5-HT1A BP in MDD (only) was related to a substantial memory bias toward negative information, but intact resolution of interfering cognitive stimuli and greater engagement of Cognitive Control circuitry. The serotonin transporter risk allele was associated with lower 1a BP and the corresponding imaging and cognitive IPs in MDD. Lowered 5HT 1a BP was present in half of the MDD group relative to the control group. Lowered 5HT 1a BP may represent a subtype including decreased engagement of Cognitive Control network and impaired resolution of interfering cognitive stimuli. Future investigations might link lowered 1a BP to neurobiological pathways and markers, as well as probing subtype-specific treatment targets. (shrink)

Traditional logical empiricist and more recent historicist positions on the logic of discovery are briefly reviewed and both are found wanting. None have examined the historical detail now available from recent research on Darwin, from which there is evidence for gradual transition in descriptive and explanatory concepts. This episode also shows that revolutionary research can be directed by borrowed metascientific objectives and heuristics from other disciplines. Darwin's own revolutionary research took place within an ontological context borrowed from non evolutionary predecessors (...) with methodological objectives borrowed from and justified by their success in Newton's physics. The logic of discovery is not a special form of inference from observation to theory, but rather a theory of the rationality of research, including principles bearing upon the rational choice of problems, or epistemic objectives, and heuristic, or means to solving the problems. Such choices can be justified only locally in the context of a relatively stable background ontology and substantive epistemology, not globally for all science. (shrink)

In the past three decades there has been a rapid development of the formal machinery for modal logic. Quantified modal logic has developed along with a semantics and model theory that is appropriate to it. With this technical development there has been relatively little discussion of what modality is all about. There are two fundamental questions that have gone unanswered. First, to what does necessity amount? Is this a new logical notion, or is it something that can be further analyzed (...) in terms of other notions that we already have at our disposal? The second question is what makes truths involving necessity true? What is their ontological grounding in the world? This essay is directed at the first of these questions. ;There are three possible reductions of metaphysical modality. First, there is the reduction suggested by the semantics for modal logic: a reduction in terms of possible worlds. Second, there is the reduction in terms of cognition. What is possible is what is conceivable. Third, there is the reduction in terms of language. Necessities arise from the structures of language and/or language use. ;I argue that none of these is successful. All of them suffer either from presupposing some form of metaphysical necessity in the reductive base, rendering them circular and not truly reductive, or they do not do justice to the modality being reduced. ;Since necessity is not reducible to any non-modal features of the world, we need to determine whether we ought to reject it as unacceptable on this basis, or whether we ought to retain it, but treat is as a new primitive that is introduced into a philosophical or logical theory. I urge the latter course is the one that we ought to take because without it too many things will likewise be deemed unacceptable. Causal necessity and explanation, normally accepted theories or knowledge and perception, logic and logical validity, and one common manner of distinguishing sets from properties will be deemed unacceptable if de re necessity is unacceptable. All of these presuppose de re metaphysical necessity in some way. I conclude that de re metaphysical necessity ought to be retained in our theory as primitive, unanalyzable notion. (shrink)

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)

This paper is concerned with the wholly metaphysical question of whether necessity and possibility rest on nonmodal foundations—whether the truth conditions for modal statements are, in the final analysis, nonmodal. It is argued that Lewis’s modal realism is either arbitrary and stipulative or else it is circular. Even if there were Lewisean possible worlds, they could not provide the grounds for modality. D. M. Armstrong’s combinatorial approach to possibility suffers from similar defects. Since more traditional reductions to cognitive or linguistic (...) facts suffer similar fates, the conclusion that the alethic modality is primitive and incapable of reduction is offered. (shrink)

Thomas Nickles challenges my thesis that innovative discoveries can be based on deliberately chosen problems and research strategies. He suggests that all significant innovation can be seen as such only in retrospect and that its generation must be serendipitous. Here I argue in response that significant innovations can and do often arise from self conscious critical appraisal of orthodox practice combined with regulated though speculative abductive argumentation to alternative explanatory schemata. Orthodox practice is not based upon monolithic systems of belief (...) about the subject of inquiry. Rather major domains of scientific practice often are approached from different conceptualizations that provide grounds for critical dialectic and consilient empirical information. Abductive arguments that meet appropriate conditions of likelihood, probability and analogy are an important means of justifying allocating resources to innovative practices that have yet to produce products that can rival those of established orthodoxy.

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.

The story of the show, The Good Place, begins with a common picture of what happens to us after we die. One of the key philosophical issues in the story involves how to assess correctly the moral goodness or badness of a person's life on Earth, since this is the basis of the judgment concerning their eternal destiny. Thomas Nagel claims that there are four kinds of “moral luck”: luck in the circumstances in which we find ourselves, luck with respect (...) to our constitution or character, luck with respect to the results of our actions, and luck with respect to having free choices at all. Perhaps one moral of the story of The Good Place is that life is really complicated, morally speaking—people are not simply good or evil, and cannot be judged easily. (shrink)

In the early 1880s, Henri Poincaré discovered an equilibrium figure for uniformly-rotating fluid masses—the pear, or piriform figure—and speculated that in certain circumstances the pear splits into two unequal parts, and provides thereby a model for the origin of binary stars. The contemporary emergence of photometric and spectroscopic studies of variable stars fueled the first models of eclipsing binaries, and provided empirical support for a realist view of equilibrium figures—including the pear—in the cosmic realm. The paper reviews astrophysical interpretation of (...) the Poincaré pear and the Poincaré-Darwin fission hypothesis with respect to research on variable stars from 1885 to 1901. (shrink)

Recently-discovered manuscripts throw new light on Poincaré’s discovery of the Lorentz group, and his ether-based interpretation of the Lorentz transformation. At first, Poincaré postulated longitudinal contraction of bodies in motion with respect to the ether, and ignored time deformation. In April, 1909, he acknowledged temporal deformation due to translation, obtaining thereby a theory of relativity more compatible with those of Einstein and Minkowski.

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.

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)

This chapter contains sections titled: The Present Moment Sterner on Returning to the Present Clock Time and Experienced Time Notes.

This collection was inspired by the observation that film remakes offer us the opportunity to revisit important issues, stories, themes, and topics in a manner that is especially relevant and meaningful to contemporary audiences. Like mythic stories that are told again and again in differing ways, film remakes present us with updated perspectives on timeless ideas. While some remakes succeed and others fail aesthetically, they always say something about the culture in which_and for which_they are produced. Contributors explore the ways (...) in which the fears of death, loss of self, and bodily violence have been expressed and then reinterpreted in such films and remakes as Invasion of the Body Snatchers, Night of the Living Dead, and Dawn of the Dead. Films such as Rollerball, The Ring, The Grudge, The Great Yokai Wars, and Insomnia are discussed as well because of their ability to give voice to collective anxieties concerning cultural change, nihilism, and globalization. While opening on a note that emphasizes the compulsion of filmmakers to revisit issues concerning fear and anxiety, this collection ends by using films like Solaris, King Kong, Star Trek, Doom, and Van Helsing to suggest that repeated confrontation with these issues allows the opportunity for creative and positive transformation.

Systematic entomology flourished as a branch of Natural History from the 1750s to the end of the nineteenth century. During this interval, the “era of Heroic Entomology,” the majority of workers in the field were dedicated amateurs. This article traces the demographic and occupational shifts in entomology through this 150-year interval and into the early twentieth century. The survey is based on entomologists who studied beetles (Coleoptera), and who named sufficient numbers of species to have their own names abbreviated by (...) subsequent taxonomists. In the eighteenth century, 27 entomologists achieved this level of prominence, of whom 37% were academics, 19% were doctors, 11% had private incomes, 19% were clergymen, and 8% were government officials. Many of those with private incomes were members of the European aristocracy, and all but one were European men. The nineteenth century list included 192 entomologists, of whom 17% were academics, 16% were museum curators, 2% were school teachers, 15% were doctors, 6% were military men, 7% were merchants, 2% were government entomologists, 6% had private incomes, 5% were clergymen, 5% were government officials, and 4% were lawyers. The demographics of entomology shifted dramatically in the nineteenth century. Whereas many of the noteworthy entomologists of the eighteenth century were German, Swedish, or French, in the nineteenth century, many more European countries are represented, and almost one-fifth of the noteworthy entomologists were from the United States. The nineteenth century list, like the eighteenth century list, contains no women. By the twentieth century, 63% of 178 noteworthy systematic entomologists were paid professionals, teaching entomology courses in universities, or studying insect taxonomy in museums and government-sponsored laboratories. Only one person on the twentieth century list had a private income, but women (ten individuals) were included on the list for the first time. (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.

Previous work demonstrates that music with more surprising chords tends to be perceived as more enjoyable than music with more conventional harmonic structures. In that work, harmonic surprise was computed based upon a static distribution of chords. This would assume that harmonic surprise is constant over time, and the effect of harmonic surprise on music preference is similarly static. In this study we assess that assumption and establish that the relationship between harmonic surprise and music preference is not constant as (...) time goes on. Analyses of harmonic surprise and preference from 1958 to 1991 showed increased harmonic surprise over time, and that this increase was significantly more pronounced in preferred songs. Separate analyses showed similar increases over the years from 2000 to 2019. As such, these findings provide evidence that the human perception of tonality is influenced by exposure. Baseline harmonic expectations that were developed through listening to the music of “yesterday” are violated in the music of “today,” leading to preference. Then, once the music of “today” provides the baseline expectations for the music of “tomorrow,” more pronounced violations—and with them, higher harmonic surprise values—become associated with preference formation. We call this phenomenon the “Inflationary-Surprise Hypothesis.” Support for this hypothesis could impact the understanding of how the perception of tonality, and other statistical regularities, are developed in the human brain.

Prominent atheists claim the Bible is a racist text. Yet Dr. Martin Luther King Jr. read it daily. Then again, so did many ardent segregationists. Some atheists claim religion serves to oppress the masses. Yet the classic text of the French Revolution, What is the Third Estate?, was written by a priest. On the other hand, the revolutionaries ended up banning religion. What do we make of religion's confusing role in history? And what of religion's relationship to science? Some scientists (...) claim that we have no free will. Others argue that advances in neurobiology and physics disprove determinism.

The result is a fresh, modern re-evaluation of religion and of atheism. (shrink)

According to modalism, modality is primitive. In this paper, we examine the implications of this view for modal epistemology, and articulate a modalist account of modal knowledge. First, we discuss a theoretical utility argument used by David Lewis in support of his claim that there is a plurality of concrete worlds. We reject this argument, and show how to dispense with possible worlds altogether. We proceed to account for modal knowledge in modalist terms.
