L’expérience visuelle est-elle une relation ou une représentation ? Le relationnisme et l’intentionnalisme à l’épreuve des sciences cognitives
No full textInternational audienceThe naïve conception of visual experience depicts such experience as a direct, primitive relation between the seeing subject and the object seen. It hinges on an opposition between the visual relation and the mental representation of the object seen in visual imagination or in the vision of images. The aim of this article is to suggest that the naïve opposition between relation and representation is still philosophically and scientifically relevant. Two philosophical theories of perception are presented: Relationalism takes up the spirit of the naïve conception by analysing visual experience as a non-representational relation to the object seen, whereas intentionalism rejects the naïve conception as inadequate and considers visual experience to be representational through and through. After introducing a general notion of representation acceptable to both sides, we examine a body of works from cognitive science that can mediate the debate between relationalism and intentionalism. The main argument propounded is that relationalism is compatible with the scientific data at our disposal on the cognitive processes related to vision. Relationalism has an additional philosophical advantage since it allows us to understand how mental representations, including visual ones, can be based on a more direct cognitive relation – in other words, an intrinsically relational one – to the visible world.La conception naïve de l’expérience visuelle dépeint celle-ci comme une relation directe, primitive, entre le sujet voyant et l’objet vu. Elle repose sur une opposition entre la relation visuelle et la représentation mentale de l’objet vu dans l’imagination visuelle ou la vision des images. Le but de cet article est de suggérer que l’opposition naïve entre relation et représentation présente un intérêt philosophique et scientifique parfois sous-estimé. Deux théories philosophiques de la perception sont présentées : le relationnisme reprend l’esprit de la conception naïve en analysant l’expérience visuelle comme une relation non représentationnelle à l’objet vu, alors que l’intentionnalisme rejette la conception naïve comme inadéquate et considère que l’expérience visuelle est représentationnelle de part en part. Après avoir introduit une notion générale de « représentation » acceptable par les deux parties, nous examinons un ensemble de travaux issus des sciences cognitives et susceptibles d’arbitrer le débat entre relationnisme et intentionnalisme. La thèse principale défendue est que le relationnisme est compatible avec les données scientifiques à notre disposition sur les processus cognitifs liés à la vision. Le relationnisme présente également un avantage philosophique puisqu’il permet de comprendre comment les représentations mentales, y compris visuelles, peuvent être fondées sur un rapport cognitif plus direct, c’est-à-dire intrinsèquement relationnel, au monde visible

Disease, perceived infectability and threat reactivity: A COVID-19 study
No full textInternational audienceUsing a two-wave online experiment, we investigate whether COVID-19 exposure changes participants' threat-detection threshold. Threat reactivity was measured in a signal detection task among 277 British adults who also reported how vulnerable they felt to infectious diseases. Participants' data were then matched to the local number of confirmed COVID-19 cases announced by the NHS every day. We found that participants who perceive themselves as more likely to catch infectious diseases displayed higher threat reactivity in response to increased COVID-19 cases
A truth and Veridicality in Grammar and Thought: Mood, Modality, and Propositional Attitudes
No full textInternational audienceCan language directly access what is true, or is the truth judgment affected by the subjective, perhaps even solipsistic, constructs of reality built by the speakers of that language? The construction of such subjective representations is known as veridicality, and in this book Anastasia Giannakidou and Alda Mari deftly address the interaction between truth and veridicality in the grammatical phenomena of mood choice: the indicative and subjunctive choice in the complements of modal expressions and propositional attitude verbs.Combining several strands of analysis—formal linguistic semantics, syntactic theory, modal logic, and philosophy of language—Giannakidou and Mari’s theory not only enriches the analysis of linguistic modality, but also offers a unified perspective of modals and propositional attitudes. Their synthesis covers mood, modality, and attitude verbs in Greek and Romance languages, while also offering broader applications for languages lacking systematic mood distinction, such as English. Truth and Veridicality in Grammar and Thought promises to shape longstanding conversations in formal semantics, pragmatics, and philosophy of language, among other areas of linguistics
Why Imaginary Worlds? The psychological foundations and cultural evolution of fictions with imaginary worlds
No full textInternational audienceWhy do fiction makers spend much time and money inventing imaginary worlds? Why are fictions with such imaginary worlds so successful? Current views in cultural evolution do not explain this massive cultural phenomenon. We argue that imaginary worlds tap into exploratory preferences which have evolved in a wide range of species to propel individuals toward new environments. After reviewing research on exploratory behaviors and preferences, we argue that this hypothesis explains the way imaginary worlds evolved culturally, their recent striking success, their shape and their distribution across time and populations
Discourse anaphora – Theoretical perspectives
No full textInternational audienceThe sign language modality provides unique advantages to the study of pronouns and discourse anaphora. The study of pronouns and anaphora has been integral to the study of formal semantics, giving a variety of insights into the logic underlying natural language. In the values that they can take, pronouns reveal the primitive semantic objects that natural language can make reference to. The sign language modality provides unique advantages to the study of pronouns and discourse anaphora. A precondition for using sign language data to bear on theories of pronouns for spoken language – or vice versa – is establishing that pronouns in sign language and pronouns in spoken language are indeed part of the same abstract pronominal system. Syntactically, pronouns in spoken language are characterized by a range of constraints on distribution and co-reference.

Boundaries in space and time: Iconic biases across modalities
No full textInternational audienceThe idea that the form of a word reflects information about its meaning has its roots in Platonic philosophy, and has been experimentally investigated for concrete, sensory-based properties since the early 20th century. Here, we provide evidence for an abstract property of ‘boundedness’ that introduces a systematic, iconic bias on the phonological expectations of a novel lexicon. We show that this abstract property is general across events and objects. In Experiment 1, we show that subjects are systematically more likely to associate sign language signs that end with a gestural boundary with telic verbs (denoting events with temporal boundaries, e.g., die, arrive) and with count nouns (denoting objects with spatial boundaries, e.g., ball, coin). In Experiments 2–3, we show that this iconic mapping acts on conceptual representations, not on grammatical features. Specifically, the mapping does not carry over to psychological nouns (e.g. people are not more likely to associate a gestural boundary with idea than with knowledge). Although these psychological nouns are still syntactically encoded as either count or mass, they do not denote objects that are conceived of as having spatial boundaries. The mapping bias thus breaks down. Experiments 4–5 replicate these findings with a new set of stimuli. Finally, in Experiments 6–11, we explore possible extensions to a similar bias for spoken language stimuli, with mixed results. Generally, the results here suggest that ‘boundedness’ of words' referents (in space or time) has a powerful effect on intuitions regarding the form that the words should take
Interacting with volatile environments stabilizes hidden-state inference and its brain signatures
No full textInternational audienceAbstract Making accurate decisions in uncertain environments requires identifying the generative cause of sensory cues, but also the expected outcomes of possible actions. Although both cognitive processes can be formalized as Bayesian inference, they are commonly studied using different experimental frameworks, making their formal comparison difficult. Here, by framing a reversal learning task either as cue-based or outcome-based inference, we found that humans perceive the same volatile environment as more stable when inferring its hidden state by interaction with uncertain outcomes than by observation of equally uncertain cues. Multivariate patterns of magnetoencephalographic (MEG) activity reflected this behavioral difference in the neural interaction between inferred beliefs and incoming evidence, an effect originating from associative regions in the temporal lobe. Together, these findings indicate that the degree of control over the sampling of volatile environments shapes human learning and decision-making under uncertainty
Agential capacities: a capacity to guide
No full textInternational audienceIn paradigm exercises of agency, individuals guide their activities toward some goal. A central challenge for action theory is to explain how individuals guide. This challenge is an instance of the more general problem of how to accommodate individuals and their actions in the natural world, as explained by natural science. Two dominant traditions-primitivism and the causal theory-fail to address the challenge in a satisfying way. Causal theorists appeal to causation by an intention, through a feedback mechanism, in explaining guidance. Primitivists postulate primitive agential capacities in their explanations. The latter neglect to explain how primitive capacities integrate with findings from natural science. The former do not explain why some feedback mechanism's activity amounts to the agent's guidance. In this paper I argue that both traditions should acknowledge a capacity to guide, as actually constituted by the executive system. I argue that appeals to this empirically discovered psychological system explain how individuals guide in a way that integrates with explanations from cognitive science. Individuals' capacity to guide is embedded in the natural world through the activity of its constituent (mechanistic) components
