We discuss five basic principles of E-Z Reader in terms of their potential for models of eye-movement control in object and scene perception. We identify several obstacles which may hinder the extrapolation of the E-Z Reader principles to nonreading tasks, yet find that sufficient similarities remain to justify using E-Z Reader as a guide for modeling eye-movement control in object and scene perception.

To eliminate the leap of faith required to explain how visual consciousness arises from visual representation, O'Regan & Noë focus on the sensorimotor interaction with the outside world and ban internal representations from their account of vision. We argue that evidence for transsaccadic representations necessitates a central position for an internal, on-line stimulus rendition in any adequate theory of vision.

This essay takes as its point of departure Charles Taylor's contention, in Sources of the Self that literature — and in particular the poetry associated with what he calls'Romantic expressivism' — enables an articulation of constitutive goods that can figureas a viable alternative for the theistic support of our moral commitments. While Taylordeserves credit for his honest attempt to take literature philosophically seriously, his cavalier treatment of the actual texts he invokes to underpin his argument tends to thwart his enterprise. (...) By way of a preliminary, broadly deconstructive reading of a set of texts also used by Taylor , I argue that literary texts simultaneously invite and resist transcendentalising interpretations such as Taylor's. To the extent that literature allows for such interpretationsit is not an alternative for but a non-critical variation of theistic groundings; to the extent that it resists such framing it offers a singular intimation of a critical ethics that is strictly insupportable but not therefore irresponsible.

Problems arise when applying the current procedural conceptualization of decision-making capacity to paediatric healthcare: Its emphasis on content-neutrality and rational cognition as well as its implicit assumption that capacity is an ability that resides within a person jeopardizes children’s position in decision-making. The purpose of the paper is to challenge this dominant account of capacity and provide an alternative for how capacity should be understood in paediatric care. First, the influence of developmental psychologist Jean Piaget upon the notion of capacity (...) is discussed, followed by an examination of Vygostky’s contextualist view on children’s development, which emphasizes social interactions and learning for decision-making capacity. In drawing parallels between autonomy and capacity, substantive approaches to relational autonomy are presented that underline the importance of the content of a decision. The authors then provide a relational reconceptualization of capacity that leads the focus away from the individual to include important social others such as parents and physicians. Within this new approach, the outcome of adults’ decision-making processes is accepted as a guiding factor for a good decision for the child. If the child makes a choice that is not approved by adults, the new conceptualization emphasizes mutual exchange and engagement by both parties. (shrink)

Davidson's anomalous monism, his argument for the identity between mental and physical event tokens, has been frequently attacked, usually demanding a higher degree of physicalist commitment. My objection runs in the opposite direction: the identities inferred by Davidson from mental causation, the nomological character of causality and the anomaly of the mental are philosophically problematic and, more dramatically, incompatible with his famous argument against the third dogma of empiricism, the separation of content from conceptual scheme. Given the anomaly of the (...) mental and the absence of psychophysical laws, there are no conceptual resources to relate mental and physical predicates. We fall in the third dogma if we claim that the very same token event is mental and physical. One of the premises must be rejected: I will claim that we do not need a law to subsume cause and effect to be entitled to speak of causation. Davidson has never offered an argument to back this premise. Against such a dogma I will sketch some ideas pointing towards a different conception of causality, singularist and undetachable from explanatory practices. (shrink)

In this paper we consider an intuitionistic variant of the modal logic S4 (which we call IS4). The novelty of this paper is that we place particular importance on the natural deduction formulation of IS4— our formulation has several important metatheoretic properties. In addition, we study models of IS4— not in the framework of Kirpke semantics, but in the more general framework of category theory. This allows not only a more abstract definition of a whole class of models but also (...) a means of modelling proofs as well as provability. (shrink)

There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors that are crucial for the reproductive success of animals living in groups. The Perception-Action Model, (...) together with an understanding of how representations change with experience, can explain the major empirical effects in the literature. It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations. Key Words: altruism; cognitive empathy ; comparative; emotion; emotional contagion; empathy ; evolution; human; perception-action; perspective taking. (shrink)

Nowadays many debates are going on that relate to the agricultural and food sector. It looks as if present technological and organizational developments within the agricultural and food sector are badly geared to societal needs and expectations. In this article we briefly present a toolkit for moral communication within the food chain. This toolkit is developed as part of a European research project. Next, we discuss what such a toolkit can bring about, given the characteristics of the present day agricultural (...) and food sector and its wider context. We defend that the toolkit can be seen as one of the mechanisms that can help enterprises in the agricultural and food sector to be accountable. It should, however, be complemented with other mechanisms, first, to empower the wider public and, second, to stimulate a dialogue, on a more equal footing, between public authorities, citizens, and economic actors.

— We prescnt here a comparative study on the decay of chlorophyll a fluorescence yield in thylakoid membranes and photosystem 11 ‐enriched samples, measured with multifrequency cross‐correlation phase fluorometry. These measurements confirm the general conclusions of Van Mieghem ef al., obtained with a flash method, on the effects of reduction of the primary quinone acceptor on ChI a fluorescence yield of PSI. Different states of the reaction centers of PSII were produced by: pretreatment with sodium dithionite and mcthyl viologen followed (...) by laser illumination: the doubly reduced QA centers: with laser illumination or pretreatment with diuron: QA‐ centers; and the addition of micromolar concentration of dichlorobenzoquinonc : oxidized QA centers. The data were analyzed with Lorentzian distribution as well as with multiexponential fluorescence decay functions. The analysis with Lorcntzian distribution function showed that upon formation of QA. the major lifetime distribution peak shifted to longer lifetimes: from 0.25 ns to 1.66 ns and from 0.24 ns to 1.31 ns. However, when QAHZ was formed, the lifetime distribution peaks shifted back to shorter lifetimes both in thylakoids and PSIl membranes. Multiexponential analysis showed three lifetime components: fast, middle and slow. When QA was formed in PS11 centers, the amplitude of the fast Component decreased, but both thc amplitude and the lifetime of the middle component increased severalfold. However, when QA was doubly reduccd, the amplitude of the fast component increased and the amplitude of the middle component decreased: in addition, the lifetime of the slow component increased. All of the above results are consistent with the conclusions that PS11 charge separation is decreased when QA is formed and increased when doubly reduced QA is formed.

Morality is often defined in opposition to the natural "instincts," or as a tool to keep those instincts in check. New findings in neuroscience, social psychology, animal behaviour, and anthropology have brought us back to the original Darwinian position that moral behaviour is continuous with the social behavior of animals, and most likely evolved to enhance the cooperativeness of society. In this view, morality is part of human nature rather than its opposite. This interdisciplinary volume debates the origin and working (...) of human morality within the context of science as well as religion and philosophy. Experts from widely different backgrounds speculate how morality may have evolved, how it develops in the child, and what science can tell us about its working and origin. They also discuss how to deal with the age-old facts-versus-values debate, also known as the naturalistic fallacy. The implications of this exchange are enormous, as they may transform cherished views on if and why we are the only moral species. (shrink)

In recent years, functional connectivity in the developmental science received increasing attention. Although it has been reported that the anatomical connectivity in the preterm brain develops dramatically during the last months of pregnancy, little is known about how functional and effective connectivity change with maturation. The present study investigated how effective connectivity in premature infants evolves. To assess it, we use EEG measurements and graph-theory methodologies. We recorded data from 25 preterm babies, who underwent long-EEG monitoring at least twice during (...) their stay in the NICU. The recordings took place from 27 weeks postmenstrual age until 42 weeks PMA. Results showed that the EEG-connectivity, assessed using graph-theory indices, moved from a small-world network to a random one, since the clustering coefficient increases and the path length decreases. This shift can be due to the development of the thalamocortical connections and long-range cortical connections. Based on the network indices, we developed different age-prediction models. The best result showed that it is possible to predict the age of the infant with a root mean-squared error equal to 2.11 weeks. These results are similar to the ones reported in the literature for age prediction in preterm babies. (shrink)

This study aims to contribute to emerging human-robot interaction research by adding longitudinal findings to a limited number of long-term social robotics home studies. We placed 70 robots in users’ homes for a period of up to six months, and used questionnaires and interviews to collect data at six points during this period. Results indicate that users’ evaluations of the robot dropped initially, but later rose after the robot had been used for a longer period of time. This is congruent (...) with the so-called mere-exposure effect, which shows an increasing positive evaluation of a novel stimulus once people become familiar with it. Before adoption, users focus on control beliefs showing that previous experiences with robots or other technologies allows to create a mental image of what having and using a robot in the home would entail. After adoption, users focus on utilitarian and hedonic attitudes showing that especially usefulness, social presence, enjoyment and attractiveness are important factors for long-term acceptance.
