Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect (delayed response due to interference) elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)

This paper analyzes the scientific achievements of the noted arabist Salvador Vila Hernández, chiefly his dedication to research and teaching in the universities and Schools of Arabic Studies of Madrid and Granada. His work is placed in the intellectual context of those years, during which he initiated energetically the specialized study of the history of law and of Islamic institutions, especially with reference to al-Andalus.

Revendo recentemente o ótimo filme “A Vila”, do diretor indiano M. Night Shyamalan (o mesmo diretor de “O Sexto Sentido”, “Corpo Fechado” e “Sinais”), é possível entender os motivos que levaram os fundadores do vilarejo fictício a criar um mundo à parte para as futuras gerações. O filme, de 2004, é inserido no gênero “suspense” por conta de sua história central em torno de uma lenda sobre criaturas aterradoras que vivem na floresta. Estas são o empecilho para que os (...) moradores cultivem o desejo de deixar o único lugar que conhecem. (shrink)

IntroductionBisphenol A is highly debated and studied in relation to a variety of health outcomes. This large variation in the literature makes BPA a topic that is prone to selective use of literature, in order to underpin one’s own findings and opinion. Over time, selective use of literature, by means of citations, can lead to a skewed knowledge development and a biased scientific consensus. In this study, we assess which factors drive citation and whether this results in the overrepresentation of (...) harmful health effects of BPA.MethodsA citation network analysis was performed to test various determinants of citation. A systematic search identified all relevant publications on the human health effect of BPA. Data were extracted on potential determinants of selective citation, such as study outcome, study design, sample size, journal impact factor, authority of the author, self-citation, and funding source. We applied random effect logistic regression to assess whether these determinants influence the likelihood of citation.ResultsOne hundred sixty-nine publications on BPA were identified, with 12,432 potential citation pathways of which 808 citations occurred. The network consisted of 63 cross-sectional studies, 34 cohort studies, 29 case-control studies, 35 narrative reviews, and 8 systematic reviews. Positive studies have a 1.5 times greater chance of being cited compared to negative studies. Additionally, the authority of the author and self-citation are consistently found to be positively associated with the likelihood of being cited. Overall, the network seems to be highly influenced by two highly cited publications, whereas 60 out of 169 publications received no citations.ConclusionIn the literature on BPA, citation is mostly driven by positive study outcome and author-related factors, such as high authority within the network. Interpreting the impact of these factors and the big influence of a few highly cited publications, it can be questioned to which extent the knowledge development in human literature on BPA is actually evidence-based.

The network model of EEG formation has revealed a unified mechanism for disparate EEG phenomena: for various reactions as well as for ontogenetic and phylogenetic differences. EEG rhythmicity was shown to be an external manifestation of the functioning of the intracortical stabilizing system which provides normal informational operations in the cerebral cortex.

Postmodernism once more—that breach has begun to yawn! I return to it by way of pluralism, which itself has become the irritable condition of postmodern discourse, consuming many pages of both critical and uncritical inquiry. Why? Why pluralism now? This question recalls another that Kant raised two centuries ago—“Was heist Aufklärung?”—meaning, “Who are we now?” The answer was a signal meditation on historical presence, as Michel Foucault saw.1 But to meditate on that topic today—and this is my central claim—is really (...) to inquire ‘Was heist Postmodernismus?”Pluralism in our time finds itself in the social, aesthetic, and intellectual assumptions of postmodernism—finds its ordeal, its rightness, there. I submit, further, that the critical intentions of diverse American pluralists—M. H. Abrams, Wayne Booth, Kenneth Burke, Matei Calinescu, R. S. Crane, Nelson Goodman, Richard McKeon, Stephen Pepper, not to mention countless other artists and thinkers of our moment—engage that overweening query, “What is postmodernism?,” engage and even answer it tacitly. In short, like a latter-day M. Jourdain, they have been speaking postmodernism all their lives without knowing it.But what is postmodernism? I can propose no rigorous definition of it, any more than I could define modernism itself. For the term has become a current signal of tendencies in theater, dance, music, art, and architecture; in literature and criticism; in philosophy, psychoanalysis, and historiography; in cybernetic technologies and even in the sciences. Indeed, postmodernism has now received the bureaucratic accolade of the National Endowment for the Humanities, in the form of a Summer Seminar for College Teachers; beyond that, it has penetrated the abstractions of “late” Marxist critics who, only a decade ago, dismissed postmodernism as another instance of the dreck, fads, and folderol of a consumer society. Clearly, then, the time has come to theorize the term, if not define it, before it fades from awkward neologism to derelict cliché without ever attaining to the dignity of a cultural concept. 1. “Maybe the most certain of all philosophical problems is the problem of the present time, of what we are, in this very moment,” writes Michel Foucault in “The Subject and Power,” reprinted as “Afterword” in Michel Foucault: Beyond Structuralism and Hermeneutics, ed.

More than one third of the human brain is devoted to the processes of seeing - vision is after all the main way in which we gather information about the world. But human vision is a dynamic process during which the eyes continually sample the environment. Where most books on vision consider it as a passive activity, this book is unique in focusing on vision as an 'active' process. It goes beyond most accounts of vision where the focus is on (...) seeing, to provide an integrated account of seeing AND looking. The book starts by pointing out the weaknesses in our traditional approaches to vision and the reason we need this new approach. It then gives a thorough description of basic details of the visual and oculomotor systems necessary to understand active vision. The book goes on to show how this approach can give a new perspective on visual attention, and how the approach has progressed in the areas of visual orienting, reading, visual search, scene perception and neuropsychology. Finally, the book summarises progress by showing how this approach sheds new light on the old problem of how we maintain perception of a stable visual world. Written by two leading vision scientists, this book will be valuable for vision researchers and psychology students, from undergraduate level upwards. (shrink)

Cappelen and Hawthorne’s Relativism and Monadic Truth (2009) offers an extended defense of a thesis they call simplicity, which, in brief, holds that propositions are true or false simpliciter. Propositions are cast in their traditional roles as the contents of assertions, and as the semantic values of declarative sentences in contexts. Simplicity stands in sharp contrast to forms of relativism including, for instance, a form that hold that our claims are true or false only relative to a judge. This applies (...) especially to claims of taste, which come out true or false only relative to the judge who finds things tasty (e.g. Glanzberg 2007, Lasersohn 2005). But simplicity also rejects the more widespread temporalist view that propositions are true or false only relative to a time, and it rejects the even more widely held view that propositions are true or false only relative to a world. One reason that has been advanced for temporalism, e.g. by Kaplan (1989), is that our languages seem to contain non-trivial temporal operators. Hence, the argument goes, the semantic values of sentences need to be temporally neutral, i.e. vary for truth or falsehood with time. The same goes for possible worlds and modal operators. Hence, Kaplan and many others think of the semantic values of sentences as sets of world-time pairs. It has been tempting to apply this sort of argument much more widely, to see the semantic values of sentences as varying not just with world and time, but perhaps with location and other parameters as well.

This paper concerns a puzzle about the logical form of expressions involving repeated `and's. Obvious attempts to solve the problem fail. It happens that a proper solution surprisingly requires the semantic notions of sampling and expression. I speculate that this may provide an alternative to conversational implicature.

_Background:_ Cognitive biases play an important role in the formation and maintenance of delusions. These biases are indicators of a weak reflective mind, or reduced engaging in reflective and deliberate reasoning. In three experiments, we tested whether a bias to accept non-sense statements as profound, treat metaphorical statements as literal, and suppress intuitive responses is related to psychotic-like experiences. _Methods:_ We tested deliberate reasoning and psychotic-like experiences in the general population and in patients with a former psychotic episode. Deliberate reasoning (...) was assessed with the bullshit receptivity scale, the ontological confabulation scale and the cognitive reflection test (CRT). We also measured algorithmic performance with the Berlin numeracy test and the wordsum test. Psychotic-like experiences were measured with the Community Assessment of Psychic Experience (CAPE-42) scale. _Results:_ Psychotic-like experiences were positively correlated with a larger receptivity toward bullshit, more ontological confabulations, and also a lower score on the CRT but not with algorithmic task performance. In the patient group higher psychotic-like experiences significantly correlated with higher bullshit receptivity. _Conclusion:_ Reduced deliberate reasoning may contribute to the formation of delusions, and be a general thinking bias largely independent of a person's general intelligence. Acceptance of bullshit may be facilitated the more positive symptoms a patient has, contributing to the maintenance of the delusions. (shrink)

carrington places race and racism at the center of his densely written analysis of science fiction, fantasy, utopia, and other forms of popular culture. He moves easily between a broad range of forms, which include memoirs, television series, comic books, novels, novelizations, fandom and fanzines, and short fiction and fiction circulated on the Internet. Popular culture helps us to construct notions of identity and race, and for carrington many constituent groups, notably fans, develop its key concepts and values.Speculative fiction is (...) for carrington a framework that links these various forms of popular culture. Here, SF is a genre different from literature, as it is situated closer to, and is more deeply... (shrink)
