Nearly all research in neurofeedback since the 1960s has focused on training voluntary control over EEG constructs. By contrast, EEG state discrimination training focuses on awareness of subjective correlates of EEG states. This study presents the first successful replication of EEG alpha state discrimination first reported by Kamiya . A 150-s baseline was recorded in 106 participants. During the task, low triggered a prompt. Participants indicated “high” or “low” with a keypress response and received immediate feedback. Seventy-five percent of participants (...) achieved significant discrimination within nine sessions, with a significant learning curve effect. Performance was significantly related to physical properties of the EEG signal, including magnitude, duration, and absolute vs. relative amplitude. These results are consistent with a conceptualization of EEG state discrimination as a sensory modality, although it is also intricately related to voluntary control of these states. (shrink)

No articulation of `historical thinking' has been as influential as Sam Wineburg's position, according to which historical thinking is, fundamentally, the recognition of the ways in which the past is different than the present. Wineburg argues, further, that achieving that state is `unnatural.' This paper critiques both of these claims, arguing instead that we should replace a generic conception of historical thinking with one that is much more rooted in the specific practice of the discipline. It is surely necessary for (...) students to learn this practice, but it is not unnatural. Instead, learning to think historically is learning to speak the language of the discipline that we call ‘history.’. (shrink)

MORE THAN MOST PHILOSOPHERS, Spinoza needed a coherent and sophisticated set of views on the nature of possibility: many of his most important philosophical positions and arguments depended on it. As one example, take Ethics IP33. This Proposition—among the most famous of the Ethics— states, “Things could have been produced by God in no other way, and in no other order than they have been produced.” In a salutary attempt to clarify the meaning of IP33 et relata, Spinoza adds in (...) the first Scholium to IP33 that “by these propositions I have shown more clearly than the noon light that there is absolutely nothing in things on account of which they can be called contingent.” Now, such assertions were bound to give rise to numerous objections and Spinoza knew it. To meet these objections, he immediately proceeds to one of the most powerful: namely, are there not things that actually have been “produced by God” that need not have been “produced by God?” And would it not make sense to call these things “contingent or possible?” In reply, Spinoza reinterprets the concept of possibility. We call existing things “contingent” “only because of a defect of our knowledge.” There are, he continues, two types of deficiency that lead us to regard existing things as “contingent or possible”: either we do not know “that the thing’s essence involves a contradiction” or we do know that the thing’s essence does not involve a contradiction but we do not know enough about the “order of causes” to affirm anything “certainly about its existence.”.

ABSTRACT The media's attentive vigil over America's most militant and outrageous activists in the abortion wars has obscured a massive but quiet effort on the part of evangelicals to engage their opponents in exemplary deliberative discussions about bioethics. For a variety of reasons, activists in the pro‐life movement are more committed to carving out civic spaces for such dialogue than are their pro‐choice counterparts. This discrepancy invites investigation into the forces that promote and constrain political movements' interest in deliberation, as (...) well as highlighting the undeniable limits to deliberative ideals.

Talisse and Maloney seem to think that professors, not ordinary citizens, are the key to a more deliberative democracy. Yet these professors fail to appreciate the reasonableness of the pro‐life activists and thinkers they disagree with. For example, they falsely charge even the most deliberative groups with resurrecting an obsolete debate and framing conversations in a fallacious way. They further place an unreasonable justificatory burden on pro‐life activists and hold them culpable for framing the debate around the ontology of the (...) embryo . In drawing such a hard line between academics and activists, they also miss what has been an unavoidable partnership between academics and social movements in our imperfect deliberative republic.

Social roles theorists claim that differences between the sexes are of limited consequence. Such misperceptions lead to misunderstanding the important role of sexual selection in explaining phenotypic differences both between species and within humans. Countering these claims, we explain how sexual dimorphism in humans affect expressions of artistic display and patterns of male and female aggression across the ovulatory cycle.

This paper takes up and provides three answers to the question “Why study philosophy?” Beginning with a discussion of why this question has been ignored in literature pertaining to the teaching of philosophy, the paper turns to an analysis of what it means to ask about the importance of philosophy, pointing out that the question is ambiguous with other questions like “why should so-and-so study philosophy” or “why does so-and-so study philosophy.” The author then provides three answers that are similar (...) to those provided by Hume: one should study philosophy because it may contribute to the entertainment, instruction, and reformation of mankind. The paper argues for the superiority of these answers over traditional responses and points to the importance of this question in teaching philosophy. (shrink)

Scholars find that political elites are badly polarized over a large range of policy issues, but they tend to agree that the mass public is much more ambivalent. The abortion war in particular is regarded as one in which millions of ambivalent citizens are caught in the crossfire of polarized activists. Yet even abortion activists struggle to escape the very ambivalent sentiments that plague ordinary Americans. These common sentiments even exert a moderating influence on both movements in ways that are (...) consistent with the preferences of the American public. They also suggest that liberalism may be mired in permanent conflict and ambivalence over the scope of basic human rights. (shrink)

This paper aims to examine how specific aspects of Bakhtin's theoretical perspective might inform our understanding of improvisation. Moreover, it outlines the possible educational implications of such a perspective. Specifically, a sketch of a Bakhtinian conception of improvisation is proposed, a sketch which emphasizes the cultivation of an attitude of consciousness that leads to an understanding of improvised music making as an obligation to explore the unknown, to search for freedom through the responsibility to attend to the uniqueness of irrevocable (...) musical acts. Moreover, emphasis is given to the potential of improvisation to create a music-making context that counters monologic musical discourses, providing a site of resistance to fixity and closure. It is argued that improvisation is dialogic exactly because it creates a very special sense of interaction, which is characterized by unfinalizability and openness. At the same time, improvisation is in need of temporary finalizations which occur through the presence of the audience and the musicians' struggle to raise their minds 'above' their playing, looking at their music from outside and getting 'back in' again. It is hoped that such a perspective might provide the necessary theoretical tools for re-thinking the role of improvisation in music education. A Bakhtinian view on the experience of improvisation would, it is suggested, be educationally valuable exactly because it regards improvisation not as a problem-solving method but a problem-positing approach: as a musical practice that involves children and young people in the experiential pursuit of freedom and the understanding of the "ought" of imagining ways forward, countering monologue by allowing the flourishing of a polyphony of unmerged voices, constituting a distinctive chronotope which provides the possibility of an enactment of everyday living in musical terms. The decision to improvise marks the initiation of a search for a public musical space which is marked by the absence of fear, where exploration of musical freedom is pursued, where everything might happen but not anything goes.

Del Giudice addresses a complex and pertinent theoretical issue: the evolutionary adaptiveness of sex differences in attachment styles in relation to life history strategy. Although we applaud Del Giudice for calling attention to the problem, we regret that he does not sufficiently specify how attachment styles serve as an integral part of a coordinate life history strategy for either sex.

According to the ‘fact-plus-value’ model of pathology propounded by K. W. M. Fulford, ‘disease’ is a value term that ought to reflect a ‘balance of values’ stemming from patients and doctors and other ‘stakeholders’ in medical nosology. In the present article I take issue with his linguistic-analytical arguments for why pathological status must be relative to such a kind of medico-ethical normativity. Fulford is right to point out that Boorse and other naturalists are compelled to utilize evaluative terminology when they (...) characterize the nature of diseases and biological dysfunctions. But the relevant ‘biofunctional judgements’ are no less factual and empirical for that. While it is indeed evaluative to say that biological dysfunctions involve failures to execute naturally selected functions, such judgments are not bound to entail anything about what is good or bad for us, and what should be treated or not. In the last part of the paper I ruminate briefly on the relationship between ‘biological evaluationism’, on my construal, and descriptions of ‘causal biology’. As I note in my conclusion, a strict bioevaluative concept of disease can be valid for every species on earth, and thus be of particular usefulness in general biological contexts. (shrink)

Critics of attention-deficit/hyperactivity disorder (ADHD) have repeatedly argued that there is no proof for the condition being symptomatic of an organic brain disease and that the current "ADHD epidemic" is an expression of medicalization. To this, the supporters of ADHD can retort that the condition is only defined as a mental disorder and not a physical disease. As such, ADHD needs only be a harmful mental dysfunction, which, like other genuine disorders, can have a complex and obscure etiology. This article (...) argues that such a line of argument fails to save ADHD as a valid diagnostic category. Given the general diagnostic logic of the DSM-IV and how ADHD has been defined in terms of everyday (male) child behaviors, there are compelling grounds to disbelieve that ADHD can be a true medical syndrome united by some type of harmful dysfunction. Indeed, strong logical and empirical reasons will be adduced to show that people may qualify for ADHD diagnosis without suffering from any type of underlying pathology. (shrink)

Bringing together powerful new tools from set theory and the philosophy of language, this book proposes a solution to one of the few unresolved paradoxes from antiquity, the Paradox of the Liar. Treating truth as a property of propositions, not sentences, the authors model two distinct conceptions of propositions: one based on the standard notion used by Bertrand Russell, among others, and the other based on J.L. Austin's work on truth. Comparing these two accounts, the authors show that while the (...) Russellian conception of the relation between sentences, propositions, and truth is crucially flawed in limiting cases, the Austinian perspective has fruitful applications to the analysis of semantic paradox. In the course of their study of a language admitting circular reference and containing its own truth predicate, Barwise and Etchemendy also develop a wide range of model-theoretic techniques--based on a new set-theoretic tool, Peter Aczel's theory of hypersets--that open up new avenues in logical and formal semantics.

ABSTRACT Donald Trump’s victory depended on the defection of hundreds of longstanding Democratic communities. Trump appealed to these communities partly because he behaves like some of their most beloved politicians. Like the president, these politicians are brazen, thin skinned, nepotistic, and offer an older, boss-centered vision of politics. Trump—the anti-establishment outsider—appealed to voters in these communities because he resembles the local insiders. This appeal widens an old fault line inside the Democratic Party.

The chapter explores whether, or to what extent, recent work in experimental philosophy puts pressure on the idea that the concept of causation is ‘egalitarian’. Causal selection – where experimental subjects tend to rate the causal strength of (for example) a norm-violator more strongly than a non-norm-violator – is a well established phenomenon, and is in prima facie tension with an egalitarian conception of causation; it also, indirectly, puts prima facie pressure on the idea that causation is a worldly phenomenon (...) whose obtaining is independent of facts about norms. The chapter explores both the various psychological mechanisms and the broadly pragmatic approaches to explaining causal selection. It argues that the answer to the question whether or not the concept of causation is egalitarian is currently significantly empirically underdetermined, and suggests some avenues for further investigation.

Presents a mathematically rigorous, philosophically sound foundation for a science of information.

In this paper I argue that there is a significant but often overlooked metaphysical distinction to be made between contextualism and contrastivism. The orthodox view is that contrastivism is merely a form of contextualism. This is a mistake. The contextualist view is incompatible with certain naturalist claims about the metaphysical nature of concepts within whichever domain is being investigated, while the contrastivist view is compatible with these claims. So, choosing one view over the other will involve choosing to affirm or (...) deny a significant metaphysical claim. As such, a demarcation ought to be put in place between contextualism and contrastivism. (shrink)

Hyperproof is a system for learning the principles of analytical reasoning and proof construction, consisting of a text and a Macintosh software program. Unlike traditional treatments of first-order logic, Hyperproof combines graphical and sentential information, presenting a set of logical rules for integrating these different forms of information. This strategy allows students to focus on the information content of proofs, rather than the syntactic structure of sentences. Using Hyperproof the student learns to construct proofs of both consequence and nonconsequence using (...) an intuitive proof system that extends the standard set of sentential rules to incorporate information represented graphically. Hyperproof is compatible with various natural-deduction-style proof systems, including the system used in the authors' Language of First-Order Logic. (shrink)

Until approximately twenty years ago, advances in the study of human genetics had little influence on the practice of medicine. In the 1980s, this changed dramatically with the mapping of the altered genes that cause cystic fibrosis and Huntington disease. In just a few years, these discoveries led to DNA-based tests that enabled clinicians to determine whether prospective parents were carriers of CF or whether an individual carried the Huntington gene and, as a result, would almost certainly develop the disease.Observers (...) interested in the social and economic implications of genetic technology realized that such genetic tests could be used by insurance companies to predict which insurance applicants were likely to become ill or even die from these diseases.

A correlational pilot study (N = 143) and an integrative data analysis of two experiments (total N = 377) provide evidence linking anger to the psychology of social hierarchy. The experiments demonstrate that the experience of anger increases the psychological accessibility of implicit cognitions related to social hierarchy: compared to participants in a control condition, participants in an anger-priming condition completed word stems with significantly more hierarchy-related words. We found little support for sex differences in the effect of anger on (...) implicit hierarchy-related cognition; effects were equivalent across male and female participants. Findings fit with functionalist evolutionary views of anger suggesting that anger may motivate the use of dominance to strive for high social rank in group hierarchies. Implications for downstream behaviour, including aggression and negotiation, are discussed. (shrink)

There is a widespread and largely unchallenged assumption within philosophy that the word ‘normal’ is ambiguous: i.e., that it can mean different things in different contexts. This assumption appears in work within topics as varied as the philosophy of biology, medicine, justification, causation, and more. In this paper I argue that we currently lack any independent reason for adopting such an assumption. The reason that would most likely be offered in its favour requires us to ignore an alternative and equally (...) plausible explanation for the seeming variety of different meanings that ‘normal’ is taken to have. Meanwhile, the well-known conjunction reduction test for ambiguity provides no evidence for the ambiguity of ‘normal’, and in fact suggests that maintaining this ambiguity claim is more difficult than has been initially supposed. Therefore, with the way things stand at present, it should not be assumed without argument that ‘normal’ is an ambiguous term. (shrink)

The “straw man” prior expectation of the dominant social psychology paradigm is that humans should behave with perfect rationality and high ethical standards. The more modest claim of evolutionary psychologists is that humans have evolved specific adaptations for adaptive problems that were reliably present in the ancestral environment. Outside that restricted range of problems, one should not expect optimal behavior.

The Language of First-Order Logic is a complete introduction to first-order symbolic logic, consisting of a computer program and a text. The program, an aid to learning and using symbolic notation, allows one to construct symbolic sentences and possible worlds, and verify that a sentence is well formed. The truth or falsity of a sentence can be determined by playing a deductive game with the computer.

It has become a truism that we live in so‐called information societies where new information technologies have made information abundant. At the same time, information science has made us aware of many phenomena tied to the way we process information. This article explores a series of socio‐epistemic information phenomena resulting from processes that track truth imperfectly: pluralistic ignorance, informational cascades, and belief polarization. It then couples these phenomena with the hypothesis that modern information technologies may lead to their amplification so (...) as to give rise to what are called “infostorms.” This points to the need for studying further the exact relations between information technologies and such infostorms, as well as the ways we may design technologies to avoid being misled away from what we have good reasons to believe.
