We argue that thought insertion primarily involves a disruption of the sense of ownership for thoughts and that the lack of a sense of agency is but a consequence of this disruption. We defend the hypothesis that this disruption of the sense of ownership stems from a fail- ure in the online integration of the contextual information related to a thought, in partic- ular contextual information concerning the different causal factors that may be implicated in their production. Loss of unity (...) of consciousness, manifested by incoherent subjective experiences is a general phenomenal characteristic of schizophrenia. This loss of coherence has been hypothesized to reflect a generalized deficit of contextual information integration not conveyed by, but related to, a target event. This deficit is manifested across many cog- nitive domains. We argue that it is also manifested in the process of thinking itself, result- ing in causally decontextualized thoughts that are experienced as inserted thoughts. (shrink)

Imagine that in entering a café, you are struck by the absence of Pierre, with whom you have an appointment. Or imagine that you realize that your keys are missing because they are not hanging from the usual ring-holder. What is the nature of these absence experiences? In this article, we discuss a recent view defended by Farennikova (2012) according to which we literally perceive absences of things in much the same way as we perceive present things. We criticize and (...) reject the perceptual interpretation of absence experiences but we also reject the cognitive view which reduces them to beliefs. We propose an intermediary, metacognitive account according to which absence experiences belong to a specific kind of affective experience, involving the feeling of surprise. (shrink)

In this paper I discuss an intriguing and relatively little studied symptomatic expression of schizophrenia known as experiences of activity in which patients form the delusion that they can control some external events by the sole means of their mind. I argue that experiences of activity result from patients being prone to aberrantly infer causal relations between unrelated events in a retrospective way owing to widespread predictive deficits. Moreover, I suggest that such deficits may, in addition, lead to an aberrant (...) intentional binding effect i.e., the subjective compression of the temporal interval between an intentional action and its external effects. In particular, it might be that patient’s thoughts are bound to the external events they aimed to control producing, arguably, a temporal contiguity between these two components. Such temporal contiguity would reinforce or sustain the feeling that the patient mind is directly causally efficient. (shrink)

Sensory substitution devices make use of one substituting modality to get access to environmental information normally accessed through another modality . Based on behavioural and neuroimaging data, some authors have claimed that using a vision-substituting device results in visual perception. Reviewing these data, we contend that this claim is untenable. We argue that the kind of information processed by a SSD is metamodal, so that it can be accessed through any sensory modality and that the phenomenology associated with the use (...) of a SSD is best described in terms of spatial phenomenology, only.

We investigate the nature of the sense of presence that usually accompanies perceptual experience. We show that the notion of a sense of presence can be interpreted in two ways, corresponding to the sense that we are acquainted with an object, and the sense that the object is real. In this essay, we focus on the sense of reality. Drawing on several case studies such as derealization disorder, Parkinson’s disease and virtual reality, we argue that the sense of reality is (...) two-way independent from the spatial and sensory contents of experience. We suggest that the sense of reality is an affective experience akin to a metacognitive feeling. Finally, we present a potentially important implication of our account for the current debate between Intentionalism and Naïve Realism. Since perception is “opaque” with respect to the reality of what is perceived, Intentionalism cannot refer to the sense of reality as what differentiates perception from sensory-like experiences such as imaginings. In contrast, Naïve Realism has an independent explanation of the specificity of perception. (shrink)

Perceptual experiences have been construed either as representational mental states—Representationalism—or as direct mental relations to the external world—Disjunctivism. Both conceptions are critical reactions to the so-called ‘Argument from Hallucination’, according to which perceptions cannot be about the external world, since they are subjectively indiscriminable from other, hallucinatory experiences, which are about sense-data ormind-dependent entities. Representationalism agrees that perceptions and hallucinations share their most specific mental kind, but accounts for hallucinations as misrepresentations of the external world. According to Disjunctivism, the phenomenal (...) character of perceptions is exhausted by worldly objects and features, and thus must be different from the phenomenal character of hallucinations. Disjunctivism claims that subjective indiscriminability is not the result of a common experiential ground, but is because of our inability to discriminate, from the inside, hallucinations from perceptions. At first sight, Representationalism is more congenial to the way cognitive science deals with perception. However, empirically oriented revisions of Disjunctivism could be developed and tested by giving a metacognitive account of hallucinations. Two versions of this account can be formulated, depending on whether metacognition is understood as explicit metarepresentation or as implicit monitoring of first-order informational states. The first version faces serious objections, but the second is more promising, as it embodies a more realistic view of perceptual phenomenology as having both sensory and affective aspects. Affectbased phenomenology is constituted by various metacognitive feelings, such as the feeling of being perceptually confronted with the world itself, rather than with pictures or mere representations.

While the formulation of Mihaly Csikszentmihalyi's theory of flow, including the experience dimensions, has remained stable since its introduction in 1975, its dedicated measurement tools, research methodologies, and fields of application, have evolved considerably. Among these, education stands out as one of the most active. In recent years, researchers have examined flow in the context of other theoretical constructs such as motivation. The resulting work in the field of education has led to the development of a new model for understanding (...) flow experience in education, specifically dedicated to adult learning. As a result of both a meticulous analysis of existing models and consideration of more recent developments, a new flow scale has thus been developed. The aim of this study is therefore twofold: to validate the new flow measurement scale dedicated to the educational environment, EduFlow-2, and to test a new theoretical model. Students taking a course, some on-site and others in a MOOC, participated. Several scales were administered online at the end of the participants' course during the 2017 academic year. The factor structure of EduFlow-2 was tested using Exploratory Structural Equation Modeling. Several models were tested. The model with a second-order factor best fit the data. We tested the invariance of the flow scale measure for gender and for the type of training. We were able to show that the flow scale is invariant of the modalities of these two variables. Results revealed good psychometric qualities for the scale, making it suitable for both on-site and distance learning. The analysis also revealed significant relationships with the classic variables of motivation, self-efficacy, learning climate, and life satisfaction. Furthermore, all four dimensions of the model were found to be adequate and consistent with the underlying theoretical arguments. In the end, this new, short flow scale and the theoretical model were demonstrated to be promising for future studies in the field of education. (shrink)

An important topic in the evolution of language is the kinds of grammars that can be computed by humans and other animals. Fitch and Hauser () approached this question by assessing the ability of different species to learn 2 grammars, (AB)n and An Bn. An Bn was taken to indicate a phrase structure grammar, eliciting a center‐embedded pattern. (AB)n indicates a grammar whose strings entail only local relations between the categories of constituents. F&H's data suggest that humans, but not tamarin (...) monkeys, learn an An Bn grammar, whereas both learn a simpler (AB)n grammar (). In their experiments, the A constituents were syllables pronounced by a female voice, whereas the B constituents were syllables pronounced by a male voice. This study proposes that what characterizes the An Bn exemplars is the distributional regularities of the syllables pronounced by either a male or a female rather than the underlying, more abstract patterns. This article replicates F&H's data and reports new controls using either categories similar to those in F&H or less salient ones. This article shows that distributional regularities explain the data better than grammar learning. Indeed, when familiarized with An Bn exemplars, participants failed to discriminate A3 B2 and A2 B3 from An Bn items, missing the crucial feature that the number of As must equal the number of Bs. Therefore, contrary to F&H, this study concludes that no syntactic rules implementing embedded nonadjacent dependencies were learned in these experiments. The difference between human linguistic abilities and the putative precursors in monkeys deserves further exploration. (shrink)

L’interprétation reçue de la pensée politique de Thomas d’Aquin la situe dans une prise de distance à l’égard de l’héritage augustinien, et en particulier vis-à-vis d’un usage politique du thème de la cité de Dieu. Afin de vérifier la pertinence d’un tel jugement, rien ne valait un examen attentif, d’une part, de tous les usages que Thomas d’Aquin fait du thème des deux cités tel qu’il se trouve présent dans la Cité de Dieu, et d’autre part de toutes les références (...) à la Cité de Dieu qui ont une portée politique pour Thomas d’Aquin. Le résultat de ce repérage textuel est formel : une cité de Dieu à usage politique est effectivement introuvable chez Thomas d’Aquin, et la référence à la Cité de Dieu est un moyen pour Thomas d’Aquin de puiser à la source antique en matière politique, aux antipodes, donc, de toute forme d’« augustinisme politique ».

The view that infants possess a full-fledged propositional language-of-thought (LoT) is appealing, providing a unifying account for infants’ precocious reasoning skills in many domains. However, careful appraisal of empirical evidence suggests that there is still no convincing evidence that infants possess discrete representations of abstract relations, suggesting that infants’ LoT remains incomplete. Parallel arguments hold for perception.

In their article “Out of nowhere: thought insertion, ownership and context-integration”, Jean-Remy Martin & Elisabeth Pacherie criticize the standard approach to thought insertion. However, their criticism is based on a misunderstanding of what the standard approach actually claims. By clarifying the notions ‘sense of ownership’ and ‘sense of agency’, I show that Martin & Pacherie’s own approach can be construed as a refined version of the standard approach.

In recent years, there has been a growing interest in the application of foundational ontologies, i.e., formal ontological theories in the philosophical sense, to provide a theoretically sound foun...

The article investigates the feasibility of district heating in a small town adjacent to a Kraft pulp mill in eastern Canada. A detailed heat demand analysis is performed for all buildings using a geographical information system and archived data provided by the municipality. The study shows that the entire space heating requirement of the town can be supplied by steam from the mill, even during exceptional peak demands. A screening test based on load density indicators, however, reveals that a district (...) heating serving the entire town would probably not be economically viable. An economic analysis of partial districts show that a district covering about half of the town can be economically viable with a proper balance between the price of the steam sold by the mill to the district operator and the cost of the energy sold to customers.

ABSTRACT:Anomie is a condition in which normative guidelines for governing conduct are absent. Using survey data from a sample of U.S. manufacturing firms, we explore the impact of internal (cultural) and external (environmental) determinants of organizational anomie. We suggest that four internal organizational factors can generate or suppress organizational anomie, including strategic aggressiveness, long-term orientation, competitor orientation, and strategic flexibility. Similarly, we argue that external contextual factors, including competitive intensity and technological turbulence, can influence organizational anomie. We extend anomie and (...) ethics research by considering the impact of these firm cultural and environmental factors according to whether firms are publicly-traded or privately-held. Findings demonstrate that a number of firm cultural and environmental factors can generate or reduce anomie in firms. Moreover, strategic aggressiveness, long-term orientation, and strategic flexibility influence organizational anomie differently depending on whether the firm is publicly-traded or privately-held. Theoretical and practical implications of our findings are discussed. (shrink)

Although the importance of weak protein‐protein interactions has been understood since the 1980s, scant attention has been paid to this “quinary structure”. The transient nature of quinary structure facilitates dynamic sub‐cellular organization through loose grouping of proteins with multiple binding partners. Despite our growing appreciation of the quinary structure paradigm in cell biology, we do not yet understand how the many forces inside the cell – the excluded volume effect, the “stickiness” of the cytoplasm, and hydrodynamic interactions – perturb the (...) weakest functional protein interactions. We discuss the unresolved problem of how the forces in the cell modulate quinary structure, and to what extent the cell has evolved to exert control over the weakest biomolecular interactions. We conclude by highlighting the new experimental and computational tools coming on‐line for in vivo studies, which are a critical next step if we are to understand quinary structure in its native environment.

In this paper, we use a pseudo-algorithmic procedure for assessing an AI-generated text. We apply the Comprehensive Assessment Procedure for Natural Argumentation (CAPNA) in evaluating the arguments produced by an Artificial Intelligence text generator, GPT-3, in an opinion piece written for the Guardian newspaper. The CAPNA examines instances of argumentation in three aspects: their Process, Reasoning and Expression. Initial Analysis is conducted using the Argument Type Identification Procedure (ATIP) to establish, firstly, that an argument is present and, secondly, its specific (...) type in terms of the argument classification framework of the Periodic Table of Arguments (PTA). Procedural Questions are then used to test the acceptability of the argument in each of the three aspects. The analysis shows that while the arguments put forward by the AI text generator are varied in terms of their type and follow familiar patterns of human reasoning, they contain obvious weaknesses. From this we can conclude that the automated generation of persuasive, well-reasoned argumentation is a far more difficult task than the generation of meaningful language, and that if AI systems producing arguments are to be persuasive, they require a method of checking the plausibility of their own output.

Blood coagulation is regulated through a complex network of biochemical reactions of blood factors. The main acting enzyme is thrombin whose propagation in blood plasma leads to fibrin clot formation. Spontaneous clot formation is normally controlled through the action of different plasma inhibitors, in particular, through the thrombin binding by antithrombin. In the current study we develop a mathematical model of clot formation both in quiescent plasma and in blood flow and determine the analytical conditions on the antithrombin concentration corresponding (...) to different regimes of blood coagulation.

WHO II low grade glioma evolves inevitably to anaplastic transformation. Magnetic resonance imaging is a good non-invasive way to watch it, by hemodynamic and metabolic modifications, thanks to multinuclear spectroscopy 1H/31P. In this work we study a multi-scale minimal model of hemodynamics and metabolism applied to the study of gliomas. This mathematical analysis leads us to a fast-slow system. The control of the position of the stationary point brings to the concept of domain of viability. Starting from this system, the (...) equations bring to light the parameters that push glioma cells out of their domain of viability. Four fundamental factors are highlighted. The first two are cerebral blood flow and the rate of lactate transport through monocarboxylate transporters, which must be reduced in order to push glioma out of its domain of viability. Another factor is the intra arterial lactate, which must be increased. The last factor is pH, indeed a decrease of intra cellular pH could interfere with glioma growth. These reflections suggest that these four parameters could lead to new therapeutic strategies for the management of low grade gliomas. (shrink)

Résumé À partir du catalogue de l’exposition « La peinture photographe », voici l’évocation d’une collaboration qui commence en 1975 au Musée national d’art moderne, se continue au château d’Oiron et croise parfois l’œuvre de Marcel Duchamp. Passant de la « peinture photographe » à l’idée d’une « peinture sculptrice », Jean-Hubert Martin interroge le non-peint et les postures de la peinture.

In this paper, we formulate a procedure for assessing reasoning as it is expressed in natural arguments. The procedure is a specification of one of the three aspects of argumentation assessment distinguished in the Comprehensive Assessment Procedure for Natural Argumentation that makes use of the argument categorisation framework of the Periodic Table of Arguments. The theoretical framework and practical application of both the CAPNA and the PTA are described, as well as the evaluation procedure that combines the two. The procedure (...) is illustrated through an evaluation of the reasoning of two example arguments from a recently published text. (shrink)
