Observers inspected normal, high quality color displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display changes could either involve "Central Interest" or "Marginal Interest" locations, as determined from descriptions obtained from independent judges in a prior pilot experiment. Visual salience, as determined by luminance, color, and position of the Central and Marginal interest changes were equalized. -/- The results obtained were very similar to those obtained in (...) prior experiments showing failure to detect changes occurring simultaneously with saccades, flicker, or “mudsplashes” in the visual scene: Many changes were very hard to detect, and Marginal Interest changes were harder to detect than Central Interest changes. -/- Analysis of eye movements showed, as expected, that the probability of detecting a change depended on the eye’s distance from the change location. However a surprising finding was that both for Central and Marginal Interest changes, evenwhen observers were directly fixating the change locations (within 1 degree),more than 40% of the time they still failed to see the changes. It seems that looking at something does not guarantee you “ see” it. (shrink)

The book provides a comprehensive state-of-the-art overview of current research on cognitive and applied aspects of eye movements. The contents include peer-reviewed chapters based on a selection of papers presented at the 11th European Conference on Eye Movements (Turku, Finland 2001), supplemented by invited contributions. The ECEM conference series brings together researchers from various disciplines with an interest to use eye-tracking to study perceptual and higher order cognitive functions. The contents of the book faithfully reflect the scope and diversity of (...) interest in eye-tracking as a fruitful tool both in basic and applied research. It consists of five sections: visual information processing and saccadic eye movements; empirical studies of reading and language production; computational models of eye movements in reading; eye-tracking as a tool to study human-computer interaction; and eye movement applications in media and communication research. Each section is concluded by a commentary chapter by one of the leading authorities in the field. These commentaries discuss and integrate the contributions in the section and provide an expert view on the most significant present and future developments in the respective areas. The book is a reference volume including a large body of new empirical work but also principal theoretical viewpoints of leading research groups in the field. (shrink)

In 'Een handvol filosofen' staan de filosofen centraal die sinds de oprichting van de Vrije Universiteit in 1880 aan deze instelling verbonden zijn geweest. Het gaat hierbij niet alleen om de inhoud van hun werk, maar ook om de personen zelf. Er waren filosofiedocenten die zich met de universiteit identificeerden en zich volledig konden ontplooien. Er waren er echter ook voor wie dit niet gold, die geïsoleerd of in gewetensnood raakten. Veel filosofiestudenten waren actief betrokken bij wat er in hun (...) faculteit gebeurde. Zij namen initiatieven, protesteerden soms tegen de gang van zaken en kozen partij in conflictsituaties. Sinds het eind van de jaren zestig van de twintigste eeuw verloor de Vrije Universiteit geleidelijk haar christelijk karakter. Tegenwoordig werken alle stafleden vanuit hun eigen motivatie mee aan een hoofdzakelijk seculier geworden universiteit, die ruimte biedt voor religieuze en levensbeschouwelijke diversiteit. (shrink)

A promise to do some action seems to create a binding obligation to do that action. And yet, paradoxically, an obligation seems not to be a fact that we can create or bring into existence; we can create an obligation only by creating or bringing into existence something else. The only way to avoid the paradox is to show that the act of promising creates something other than an obligation, which nonetheless binds us to perform the action in question. After (...) considering and rejecting various options such as the promisee's expectation and the promisor's resolve, Prichard locates the bindingness of a promise in a prior general promise, which allows the noises we make when promising to generate an obligation to perform the promised action.

Change blindness illustrates a remarkable limitation in visual processing by demonstrating that substantial changes in a visual scene can go undetected. Because these changes can ultimately be detected using top–down driven search processes, many theories assign a central role to spatial attention in overcoming change blindness. Surprisingly, it has been reported that change blindness can occur during blink-contingent changes even when observers fixate the changing location [O’Regan, J. K., Deubel, H., Clark, J. J., & Rensink, R. A. . Picture (...) changes during blinks: Looking without seeing and seeing without looking. Visual Cognition, 7, 191–212]. However, eye blinks produce a transient disruption of vision that is independent of any associated changes in the retinal image. We determined whether these ‘attentive blank stares’ could occur in the absence of blink-mediated visual suppression. Using a flicker change-blindness paradigm we confirm that despite direct attentive fixations, obvious scene changes often remain undetected. We conclude that change detection involves object or feature based attentional mechanisms, which can be ‘misdirected’ despite the allocation of spatial attention to the position of the change.

I bogen "Den store humor" undersøger Harald Høffding humoren som livsanskuelse. "Den store humor" er ifølge Høffding en etisk livsholdning, som et menneske kan leve sit liv efter. Inspireret af filosoffen Søren Kierkegaards stadieteori karakteriserer Harald Høffding humoren som et etisk standpunkt, der nægter at anerkende den kristnes tragiske syn på livet. I stedet formår humoristen, at balancere livets lyse og skyggefulde sider. Humoristen lever sit liv med åbne øjne og har derfor blik for såvel verdens komik som tragik. Harald (...) Høffding (1843-1931) var teolog og filosof og virkede gennem 30 år som professor ved Københavns Universitet. I løbet af sin karriere opnåede han en central position i det danske videns- og kulturliv og nød stor anerkendelse både i og udenfor Danmark. Høffding var yderst virksom hele sit liv, og tankegodset i hans bøger er stadig relevant i dag. Udover værkerne om etik, filosofihistorie og psykologi kendes han for monografier om Søren Kierkegaard, Jean-Jacques Rousseau og Baruch Spinoza. (shrink)

Many people are worried about the harmful effects of climate change but nevertheless enjoy some activities that contribute to the emission of greenhouse gas (driving, flying, eating meat, etc.), the main cause of climate change. How should such people make choices between engaging in and refraining from enjoyable greenhouse-gas-emitting activities? In this chapter, we look at the answer provided by decision theory. Some scholars think that the right answer is given by interactive decision theory, or game theory; and moreover think (...) that since private climate decisions are instances of the prisoner’s dilemma, one rationally should engage in these activities provided that one enjoys them. Others think that the right answer is given by expected utility theory, the best-known version of individual decision theory under risk and uncertainty. In this chapter, we review these different answers, with a special focus on the latter answer and the debate it has generated. (shrink)

The article examines philosophical conceptions of responsibility found in the contributions of Martin Buber, Hans Jonas and Emmanuel Levinas. It argues that, despite the significant differences of these contributions, they all share important goals, significant structural features, and corresponding challenges. All three thinkers try to overcome the solipsistic limitations of Edmund Husserl’s phenomenology as well as the egocentrism of Heidegger’s concept of "solicitude" or "self-care." All three try to overcome the Kantian subject-object dichotomy. All three understand responsibility as a bipolar (...) relation only. In consequence, all of them face similar challenges resulting from new forms of dichotomies and the exclusion of “thirdness” that are the result of their conceptual decisions. (shrink)

The impact of digital media and technology on performance arts is evident when digital visual effects (VFX) filming techniques are introduced on a film set. Digital technologies influence the film actor’s approach to be congruent to and authentic within the circumstances of the scene. Actors require an effective skillset and strategies to successfully deliver an embodied performance aligning with the various digital VFX techniques. Focusing on imagination, action and emotion that would facilitate such an embodied performance, we drew on relevant (...) neuroscientific notions such as neuron reactivation, conceptual blending, as-if body states and affordances. Additionally, we incorporated relevant embodied performance concepts from Stanislavski, Laban/Bartenieff Movement Studies, Effector Patterns including the Emotional Body Approach and Lessac Kinesensics to the development of a digital acting programme, advancing the actor’s required skills and providing on-set digital acting strategies to support congruency with digital VFX and authenticity within the diegetic reality. The efficacy of this programme was determined by assessing pre- and post-intervention recordings of both a control and an experimental group of trained actors. Reflection-on-action journals from participants supplemented the assessment. The assessments and journals indicate that the acquired skillset and on-set digital acting strategies effectively improve the actor’s performance with digital VFX filming technology. (shrink)

Background: The factors influencing parents’ willingness to enroll their children in biobanks are poorly understood. This study sought to assess parents’ willingness to enroll their children, and their perceived benefits, concerns, and information needs under different consent and data-sharing scenarios, and to identify factors associated with willingness. Methods: This large, experimental survey of patients at the 11 eMERGE Network sites used a disproportionate stratified sampling scheme to enrich the sample with historically underrepresented groups. Participants were randomized to receive one of (...) three consent and data-sharing scenarios. Results: In total, 90,000 surveys were mailed and 13,000 individuals responded (15.8% response rate). 5737 respondents were parents of minor children. Overall, 55% (95% confidence interval 50–59%) of parents were willing to enroll their youngest minor child in a hypothetical biobank; willingness did not differ between consent and data-sharing scenarios. Lower educational attainment, higher religiosity, lower trust, worries about privacy, and attitudes about benefits, concerns, and information needs were independently associated with less willingness to allow their child to participate. Of parents who were willing to participate themselves, 25% were not willing to allow their child to participate. Being willing to participate but not willing to allow one’s child to participate was independently associated with multiple factors, including race, lower educational attainment, lower annual household income, public health care insurance, and higher religiosity. Conclusions: Fifty-five percent of parents were willing to allow their youngest minor child to participate in a hypothetical biobank. Building trust, protecting privacy, and addressing attitudes may increase enrollment and diversity in pediatric biobanks. (shrink)

This is the first sustained, whole-Bible treatment on the theme of meeting God face to face. Starting with Genesis and ending with Revelation, the author systematically covers the major events in salvation history, all of which reveal the beauty of encountering God's grace in abundance.

In this book, Phillip Wiebe examines religious, spiritual, and mystical experiences, assessing how these experiences appear to implicate a spiritual order. Despite the current prevalence of naturalism and atheism, he argues that experiences purporting to have a religious or spiritual significance deserve close empirical investigation. Wiebe surveys the broad scope of religious experience and considers different types of evidence that might give rise to a belief in phenomena such as spirits, paranormal events, God, and an afterlife. He demonstrates that there (...) are different explanations and interpretations of religious experiences, both because they are typically personal accounts, and they suggest a reality that is often unobservable. Wiebe also addresses how to evaluate evidence for theories that postulate unobservables in general, and a Theory of Spirits in particular. Calling for more rigorous investigation of these phenomena, Wiebe frames the study of religious experience among other accepted social sciences that seek to understand religion. (shrink)

The introduction of novel diagnostic techniques in clinical domains such as genomics and radiology has led to a rich ethical debate on how to handle unsolicited findings that result from these innovations. Yet while unsolicited findings arise in both genomics and radiology, most of the relevant literature to date has tended to focus on only one of these domains. In this article, we synthesize and critically assess similarities and differences between “scanning the body” and “sequencing the genome” from an ethical (...) perspective. After briefly describing the novel diagnostic contexts leading to unsolicited findings, we synthesize and reflect on six core ethical issues that relate to both specialties: terminology; benefits and risks; autonomy; disclosure of unsolicited findings to children; uncertainty; and filters and routine screening. We identify ethical rationales that pertain to both fields and may contribute to more ethically sound policies. Considerations of preserving public trust and ensuring that people perceive healthcare policies as fair also support the need for a combined debate. (shrink)

Currently, there is widespread skepticism that higher cognitive processes, given their apparent flexibility and globality, could be carried out by specialized computational devices, or modules. This skepticism is largely due to Fodor's influential definition of modularity. From the rather flexible catalogue of possible modular features that Fodor originally proposed has emerged a widely held notion of modules as rigid, informationally encapsulated devices that accept highly local inputs and whose operations are insensitive to context. It is a mistake, however, to equate (...) such features with computational devices in general and therefore to assume, as Fodor does, that higher cognitive processes must be non‐computational. Of the many possible non‐Fodorean architectures, one is explored here that offers possible solutions to computational problems faced by conventional modular systems: an ‘enzymatic’ architecture. Enzymes are computational devices that use lock‐and‐key template matching to identify relevant information (substrates), which is then operated upon and returned to a common pool for possible processing by other devices. Highly specialized enzymes can operate together in a common pool of information that is not pre‐sorted by information type. Moreover, enzymes can use molecular ‘tags’ to regulate the operations of other devices and to change how particular substrates are construed and operated upon, allowing for highly interactive, context‐specific processing. This model shows how specialized, modular processing can occur in an open system, and suggests that skepticism about modularity may largely be due to failure to consider alternatives to the standard model.

We show that arbitrary tautologies of Johansson’s minimal propositional logic are provable by “small” polynomial-size dag-like natural deductions in Prawitz’s system for minimal propositional logic. These “small” deductions arise from standard “large” tree-like inputs by horizontal dag-like compression that is obtained by merging distinct nodes labeled with identical formulas occurring in horizontal sections of deductions involved. The underlying geometric idea: if the height, h(∂), and the total number of distinct formulas, ϕ(∂), of a given tree-like deduction ∂ of a minimal (...) tautology ρ are both polynomial in the length of ρ, |ρ|, then the size of the horizontal dag-like compression ∂ᶜ is at most h(∂)×ϕ(∂), and hence polynomial in |ρ|. That minimal tautologies ρ are provable by tree-like natural deductions ∂ with |ρ|-polynomial h(∂) and ϕ(∂) follows via embedding from Hudelmaier’s result that there are analogous sequent calculus deductions of sequent ⇒ρ. The notion of dag-like provability involved is more sophisticated than Prawitz’s tree-like one and its complexity is not clear yet. Our approach nevertheless provides a convergent sequence of NP lower approximations of PSPACE-complete validity of minimal logic. (shrink)

The research climate plays a key role in fostering integrity in research. However, little is known about what constitutes a responsible research climate. We investigated academic researchers’ perceptions on this through focus group interviews. We recruited researchers from the Vrije Universiteit Amsterdam and the Amsterdam University Medical Center to participate in focus group discussions that consisted of researchers from similar academic ranks and disciplinary fields. We asked participants to reflect on the characteristics of a responsible research climate, the barriers they (...) perceived and which interventions they thought fruitful to improve the research climate. Discussions were recorded and transcribed at verbatim. We used inductive content analysis to analyse the focus group transcripts. We conducted 12 focus groups with 61 researchers in total. We identified fair evaluation, openness, sufficient time, integrity, trust and freedom to be mentioned as important characteristics of a responsible research climate. Main perceived barriers were lack of support, unfair evaluation policies, normalization of overwork and insufficient supervision of early career researchers. Possible interventions suggested by the participants centered around improving support, discussing expectations and improving the quality of supervision. Some of the elements of a responsible research climate identified by participants are reflected in national and international codes of conduct, such as trust and openness. Although it may seem hard to change the research climate, we believe that the realisation that the research climate is suboptimal should provide the impetus for change informed by researchers’ experiences and opinions.

The paper proposes to integrate literary studies in consciousness research to develop a strong ethical and existential dimension in the field. More specifically, it considers the value of fictional narrative for developing concepts of selfhood and personal identity that cohere with the reductionist explanations of human consciousness and self in modern empirical consciousness research. My central claim is that looking to the literary representations of human consciousness and existence that reject or are free from conventional essentialist ideas of self, agency, (...) and anthropocentrism can help 'normalize' the reductionist scientific descriptions of humans and reduce their psychologically and socio-culturally disruptive impact. The paper uses Virginia Woolf's The Waves as an example, showing how the novel's non-anthropocentric and non-essentialist conceptions of self and consciousness overlap with materialist theories in neuroscience and -philosophy but present these in a distinctive narrative framework and poetic terms that bring out the inherent emancipatory potential of the materialist explanation of human existence and offer the reader the possibility of relating to these experientially and emotionally.

This article suggests that humanism is a decisionism in contemporary critical political theory. Despite obvious and multiple differences, leading critical theorists like Giorgio Agamben, Slavoj Žižek, Eric Santner, and Jürgen Habermas, among others, share an investment in stabilizing the human being as a ground of the political. This stabilization of the human should concern political theorists, as this article argues, because it uncritically reproduces conceptual affinities between the notion of the human being and sovereign authority. By investing in the stability (...) and centrality of the human being, these theorists perform what will be called, paraphrasing an often neglected argument by Carl Schmitt, a decision to be human. Contrary to conventional wisdom, I argue that Schmitt’s decisionism is not merely circumscribed to sovereignty’s juridico-political dimension, but that it also includes a peculiar commitment to God’s decision to become human in Christ. Against this decisionism as humanism, the article draws on Walter Benjamin, Roberto Esposito, and Jacques Derrida to propose an alternative politics that destabilizes humanity and sovereignty through the emergence of the animal, or what will be called melancholic lycanthropy.
