Can we build endogenous expectations about the locus of occurrence of a target without being able to describe them? Participants performed cue–target detection tasks with different proportions of valid and invalid trials, without being informed of these proportions, and demonstrated typical endogenous effects. About half were subsequently able to correctly describe the cue–target relationships . However, even non-verbalizer participants showed endogenous orienting with peripheral cues , not depending solely on practice . Explicit instructions did not bring about dramatic advantages in (...) performance .With central symbolic cues, only verbalizers showed reliable endogenous effects . We concluded that endogenous orienting with peripheral cues can occur independently of participants developing explicit hypotheses about the cue–target relationships. (shrink)

I give reasons to suggest that the various ‘homogeneous substance’ objections to perdurance theory should not be regarded as raising serious difficulties. The main strategy is to show that there are equally exotic possibilities involving extended mereological simples that may turn the tables on the endurance theorist, insofar as she will have difficulties with these cases analogous to those she raises for the perdurantist. I conclude that such exotic cases are less useful that we might suppose in adjudicating between these (...) competing doctrines of persistence. (shrink)

En los últimos años, el interés por la semántica de términos ficticios ha crecido considerablemente en el marco de la tradición analítica. De forma general, es posible distinguir dos grandes tipos de propuestas semánticas: las propuestas ontológicamente comprometidas con entidades ficticias y las que evitan dicho compromiso . Entre estas últimas, se destaca la propuesta inscripcionalista de Nelson Goodman y Catherine Elgin, que constituye el eje de análisis del presente artículo. Su objetivo principal es mostrar algunas de las ventajas de (...) la propuesta inscripcionalista frente a las propuestas realistas. En la segunda sección, analizo algunas de las dificultades que conllevan las propuestas realistas y luego muestro que estas no tienen lugar en la propuesta de Goodman y Elgin. En la tercera sección, presento la propuesta inscripcionalista, centrándome en su ampliación, la noción de referencia y sus diversas modalidades, y también analizo una serie de enunciados problemáticos utilizando los modos referenciales anteriormente presentados.

In agreement with some of the ideas expressed by Perruchet & Vinter (P&V), we believe that some phenomena hitherto attributed to processing may in fact reflect a fundamental distinction between direct and reflexive forms of consciousness. This dichotomy, developed by the phenomenological tradition, is substantiated by examples coming from experimental psychology and lesion neuropsychology.

Right brain-damaged patients with unilateral neglect, who ignore left-sided visual events, may also omit left-sided details when describing known places from memory. Modulating the orienting of visual attention may ameliorate imaginal neglect. A first step toward explaining these phenomena might be to postulate that space-related imagery is a cognitive activity involving attentional and intentional aspects.

Unilateral neglect stems from a relatively selective impairment of exogenous, or stimulus-related, orienting of attention. This neuropsychological evidence parallels “change blindness” experiments, in which normal individuals lack awareness of salient details in the visual scene as a consequence of their attention being exogenously attracted by a competing event, suggesting that visual consciousness requires the integrity of exogenous orienting of attention.

BackgroundThe measures taken to contain the coronavirus disease 2019 pandemic, such as the lockdown in Italy, do impact psychological health; yet, less is known about their effect on cognitive functioning. The transactional theory of stress predicts reciprocal influences between perceived stress and cognitive performance. However, the effects of a period of stress due to social isolation on spatial cognition and exploration have been little examined. The aim of the present study was to investigate the possible effects and impact of the (...) COVID-19 pandemic on spatial cognition tasks, particularly those concerning spatial exploration, and the physiological leftward bias known as pseudoneglect. A right-hemisphere asymmetry for spatial attention processes crucially contributes to pseudoneglect. Other evidence indicates a predominantly right-hemisphere activity in stressful situations. We also analyzed the effects of lockdown on coping strategies, which typically show an opposite pattern of hemispheric asymmetry, favoring the left hemisphere. If so, then pseudoneglect should increase during the lockdown and be negatively correlated with the efficacy of coping strategies.MethodsOne week before the start of the lockdown due to COVID-19 in Italy, we had collected data from a battery of behavioral tests including tasks of peri-personal spatial cognition. During the quarantine period, from late April to early May 2020, we repeated the testing sessions with a subgroup of the same participants. At both testing sessions, participants performed digitized neuropsychological tests, including a Cancellation task, Radial Arm Maze task, and Raven’s Advanced Progressive Matrices. Participants also completed a newly developed COVID-19 Student Stress Scale, based on transactional models of stress, and the Coping Orientation to Problems Experienced—New Italian Version to assess coping orientation.ResultsThe tendency to start cancelation from a left-sided item, to explore first a left-sided arm of the maze, and to choose erroneous response items on the left side of the page on Raven’s matrices increased from T1 to T2. The degree of pseudoneglect increment positively correlated with perceived stress and negatively correlated with Positive Attitude and Problem-Solving COPE-NIV subscales.ConclusionLockdown-related stress may have contributed to increase leftward bias during quarantine through a greater activation of the right hemisphere. On the other hand, pseudoneglect was decreased for better coping participants, perhaps as a consequence of a more balanced hemispheric activity in these individuals. (shrink)

L’objectif de cette étude est de reconstituer l’explication épicurienne des phénomènes d’attraction (ὁλκή). On cherche notamment à vérifier la fiabilité du témoignage de Galien qui attribue à Épicure une théorie de l’aimantation très différente de celle qui nous a été transmise par Lucrèce dans son De rerum natura. En examinant de près la théorie exposée par Galien, je cherche à montrer que, telle qu’elle est présentée, elle n’arrive pas, d’un point de vue strictement épicurien, à rendre compte du mouvement attractif. (...) J’envisage donc deux hypothèses. Ou bien Épicure est l’auteur de la théorie transmise par Galien et, dans un deuxième moment, l’aurait mise de côté au profit d’une théorie plus solide et efficace (celle de Lucrèce), ou bien la théorie en question est une version très remaniée de la véritable théorie d’Épicure, fruit d’une réinterprétation assez libre de Galien. La deuxième possibilité me paraît être plus probable, étant donné le contexte très polémique dans lequel ce témoignage se trouve. (shrink)

The writings of the Italian philosophers Giovanni Vailati and Mario Calderoni, sometimes called logical pragmatists, are not well-known in the English-speaking countries. A recent revival of interest is due in part to the reflection in the works of these men of later developments in analytic and pragmatic philosophy. This bibliography has three parts; In Part I are listed English and French translations of some of Vailati's writings, and commentaries in English and French on his work. Part II indicates the extent (...) of Vailati's correspondence with scholars of his time, and lists reviews by Vailati of the works of his contemporaries. Part III is a list of his major writings in Italian, with English translations of the titles. (shrink)

L’objectif de cette étude est d’examiner l’hypothèse selon laquelle la quarta natura, théorisée par Épicure pour rendre compte des activités de l’âme et décrite par Lucrèce (DRN III, 237-244), résulte de l’appropriation par Épicure d’un argument aristotélicien afin de répondre aux critiques d’Aristote à l’égard de la théorie démocritéenne de l’âme. Pour ce faire, on analysera le témoignage de Cicéron (Tusc. I, 10, 22) sur le quintum genus attribué à Aristote et on rendra compte des débats sur ses sources possibles. (...) En confrontant le témoignage cicéronien avec les vers dans lesquels Lucrèce expose la théorie de la quatrième nature, on montrera les fortes ressemblances entre leurs structures argumentatives. Sur la base de la possible datation de la théorie de la quintessence et de son attribution au Péripatos du iie siècle av. J-C, on proposera d’expliquer cette similarité par l’appropriation par Lucrèce de l’argument par soustraction qui caractérise la théorie de la quintessence, à partir de laquelle il aurait conçu la théorie de la quatrième nature. Afin de vérifier l’exactitude de cette interprétation, on examinera l’hypothèse selon laquelle l’appropriation de cet argument, et donc la conception de la quatrième nature, remontent à Épicure, la paternité de l’argument par soustraction (à partir duquel les péripatéticiens postérieurs pourraient avoir conçu la théorie de la quintessence) étant alors à attribuer à Aristote. Pour ce faire, on analysera un passage du De Caelo (269a30-269b2) et un passage de La Génération des animaux (736b29-737a1) où l’argument par soustraction sert à introduire d’une part l’éther et d’autre par le pneuma. Ensuite, en s’appuyant sur l’analyse d’un passage du De Anima (405a5-7), on montrera que l’appropriation de cet argument pourrait s’expliquer par la tentative, de la part d’Épicure, de répondre à une critique aristotélicienne concernant la théorie démocritéenne de l’âme.

Cet ouvrage, Storia delle antiche teologie atomiste, est le fruit de la réélaboration d’une thèse de doctorat en philosophie rédigée et soutenue en 2016 par son auteur, Enrico Piergiacomi, à l’Université de Trente. L’objectif principal de ce travail transparaît déjà dans son titre : il s’agit, en effet, de chercher si et en quels termes il est légitime de parler de « théologies atomistes », et d’en reconstituer l’histoire. Cette étude vise à démontrer non seulement que la réflexion atomiste s...

If temporal parts are bona fide parts, then it is fitting to clarify and extend that notion (and related ones) using the resources of a theory of parts. But it often seems that those engaged in the 3D/4D debate appear to take for granted that, aside from introducing a welcome measure of rigor to the discussion, issues regarding theories of parthood can be allowed to recede into the background. What follows challenges that assumption — I demonstrate that the nature of (...) the fundamental mereological relation1 can decisively influence the outcome of the debate over persistence. In short, I show that if the fundamental mereological relation is proper parthood-at-atime then four-dimensionalism is false.2 Recognizing this does at least two things for us. First, it supplies a framework in which three-dimensionalists can clarify two things they have tended to say all along, namely that persisting things are ‘wholly present’ throughout their careers and that they do not have temporal parts. Second, it re-focuses the debate on a narrower and perhaps more tractable question: “What is the nature of the fundamental mereological relation?”. (shrink)

"Un monde fait d'atomes et de vide, des phénomènes réductibles aux mouvements et aux formes des atomes : ce sont là deux aspects bien connus de la philosophie matérialiste et mécaniste d'Épicure. Une telle conception de l'univers peut-elle cependant rendre véritablement compte de l'être vivant et de sa physiologie? Comment un rassemblement de matière aléatoirement combinée produirait-il un organisme? Et si le vivant est une sorte de mécanisme, qu'est-ce qui différencie un mécanisme vital des autres? L'ouvrage examine de façon systématique (...) les réponses épicuriennes à ces questions en s'attachant notamment à les replacer dans un dialogue avec les philosophes antérieurs, principalement Démocrite et Aristote."--Page 4 of cover.

In “Extensionality of Parthood and Composition,”1 Achille Varzi mounts a spirited defense of the extensionality of parthood, or ‘EP’. According to EP, if x and y are composite objects with all the same proper parts then x = y.2 A number of philosophers, he notes, have objected that EP is false on the grounds that, for example, a statue and lump of clay (or a tinkertoy house and the wood from which it is made, in Varzi’s example) are distinct yet (...) share all their proper parts. A number of considerations — for example, that a statue and lump of clay have different persistence conditions — are commonly raised to support this non-extensionalist conclusion. Varzi maintains, on the other hand, that this case and others like it do not support non-extensionalism. However, there are reasons to doubt the cogency of his argument. In outline, Varzi’s argument runs as follows. Suppose that (i) α and β are (say) a statue and a lump, respectively,3 and also suppose that (ii) α = β. ∗This is a draft and so unsuitable for citation in any form.

Dans l’épicurisme, la réflexion éthique trouve son fondement dans le discours sur la nature qui explique à l’individu les phénomènes qui l’entourent et qui, la plupart du temps, l’angoissent sans raison. Ce discours concerne-t-il aussi le monde végétal? Quel rôle jouent les plantes dans le Jardin d’Épicure? L’étude cherche à reconstituer la physiologie épicurienne des plantes à partir d’un témoignage contenu dans les Placita philosophorum 2. Des phénomènes comme la nutrition et la croissance, attribués à des plantes pourtant conçues comme (...) des êtres inanimés, sont à questionner. (shrink)

Current deep neural networks (DNNs) are far from being able to model the rich landscape of human visual experience. Beyond visual recognition, we explore the neural substrates of visual mental imagery and other visual experiences. Rather than shared visual representations, temporal dynamics and functional connectivity of the process are essential. Generative adversarial networks may drive future developments in simulating human visual experience.

We see things. We also perceptually demonstrate things. There seems to be some sort of link between these two phenomena. Indeed. in the standard case, the former is accompanied by a capacity for the latter. One sees a dog and can, on the basis of one’s perceptual capacities, think thoughts of the form ‘That is F’. But how strong is that link? Does seeing a thing inevitably bring with it the capacity for perceptually demonstrating it? In what follows, we argue (...) for a negative answer to this question. In so doing, we hope to shed some light on the phenomenon of perceptual demonstration. After presenting the main argument in section one, we go on in section two to consider a series of objections and replies. (shrink)

The transition of novel and potentially promising medical therapies into their initial human clinical trials can engender conflicting pressures. On the one side, because Phase I trials raise greater ethical and human protection challenges than later stage clinical trials, there is a need to proceed cautiously. This is particularly the case for Phase I trials with a novel therapy being tested in humans for the first time, usually termed first-in-human (FIH) trials, especially if the FIH trial involves significant risks. On (...) the other side, scientists interested in having their research validated, corporations with a financial interest in the field, and potential patients and patient support groups desirous of having ..

This study investigated the effect of stroking vs. simple human presence on later reactions of dairy cows to routine veterinary handling. While in two groups of cows the experimenter stroked the ventral part of the neck or the withers for three consecutive weeks, the third group was exposed to close visual presence. After the treatment period the cows were subjected to rectal palpation. The three groups differed significantly in stepping during rectal palpation, which occurred less often in Neck- and Withers-animals (...) than in control animals. Heart rate increase was significantly higher in the control group than in the two stroking groups. Previous stroking led to fewer stress reactions during the rectal palpation, possibly due to a combined effect of improved relationship towards and thus perception of humans and lasting anti-stress effects of tactile stimulation.
