In their environment, plants are continuously submitted to natural stimuli such as wind, rain, temperature changes, wounding, etc. These signals induce a cascade of events which lead to metabolic and morphogenetic responses. In this paper the different steps are described and discussed starting from the reception of the signal by a plant organ to the final morphogenetic response. In our laboratory two plants are studied: Bryonia dioica for which rubbing the internode results in reduced elongation and enhanced radial expansion and (...) Bidens pilosa for which the response occurs at distance, hence pricking the cotyledon of a plantlet induces the growth inhibition of both the hypocotyl and the axillary bud of the pricked cotyledon. Reception of the signal and transmission of the message. In Bryonia the signal is received by epidermal cells while in Bidens they are the cells adjacent to the midrib of the cotyledon which receive the mechanical signal. In both plants the message is transmitted via a wave of electric depolarization. This latter is composed of an action potential associated with a slow wave whose transmission rates are respectively 1cm s−1 and 1 mm s−1. Recent results have shown the involvement of Ca2+ in the triggering of the slow wave and the role of the H+ pump during the slow wave. Transient and fast biochemical responses. An entry of extraceilular Ca2+ into the cells and a transient increase in IP3 occur within seconds following the mechanical stimulus. At the same time, the membrane becomes more fluid, correlated with qualitative changes in phospholipids. The rapid increase in the concentration of peroxidated lipids may be correlated with ethylene biosynthesis which is stimulated after rubbing. Other parameters such as cytoplasmic pH, relative water content, hydric potential, membrane potential and modifications of K+, Mg2+-ATPase and Ca2+-ATPase activities, play a key role in the early responses induced by the traumatisms. Irreversible-biochemical responses. The mechanical stimulus performed on a Bryonia internode induces an acceleration of: i) enzymatic activities related to the lignification, ii) esterification of phenolic acids in the cell wall. Consequently the lignification process is accelerated. Storage of the information. After being received by the target cells the information can be stored during several days before being expressed. At the level of cotyledonary bud, the first message, previously stored, can be expressed or not by a second treatment. Bidens thus behaves as if it was able to “store” and to “retrieve” morphogenetic messages, using a sort of rudimentary memory. The nuclei of the bud cells of the pricked cotyledon show that these cells, initially in G2 phase, divide and then remain in the G1 phase. In Bryonia, calli derived from young stimulated internodes, keep thigmomorphogenetic characteristics during several weeks. In the last part of this paper the particularity of our plant model which permits a study of the transmission and storage of the message, is underlined. The links between the different steps induced by the stimulus are discussed. Special attention is devoted to second messengers and to the amplification of the message. (shrink)

As yet, there is no enactive account of social cognition. This paper extends the enactive concept of sense-making into the social domain. It takes as its departure point the process of interaction between individuals in a social encounter. It is a well-established finding that individuals can and generally do coordinate their movements and utterances in such situations. We argue that the interaction process can take on a form of autonomy. This allows us to reframe the problem of social cognition as (...) that of how meaning is generated and transformed in the interplay between the unfolding interaction process and the individuals engaged in it. The notion of sense-making in this realm becomes participatory sense-making. The onus of social understanding thus moves away from strictly the individual only. (shrink)

This paper comments on Gallagher’s recently published direct perception proposal about social cognition [Gallagher, S.. Direct perception in the intersubjective context. Consciousness and Cognition, 17, 535–543]. I show that direct perception is in danger of being appropriated by the very cognitivist accounts criticised by Gallagher. Then I argue that the experiential directness of perception in social situations can be understood only in the context of the role of the interaction process in social cognition. I elaborate on the role of social (...) interaction with a discussion of participatory sense-making to show that direct perception, rather than being a perception enriched by mainly individual capacities, can be best understood as an interactional phenomenon.

The blooming desert or ‘El desierto florido’ in Spanish, is a millenarian climate pattern caused by El Niño that warms the surface waters in the eastern tropical Pacific Ocean and creates the conditions for rain in the Altiplano and the Atacama Desert, north of Chile. After some millimeters of abundant rain, a rich biotic community emerges, and in a matter of hours or days, the driest surface on Earth becomes an impressive colorful habitat for more than two hundred different species (...) of eye-catching flowers that host the desert biotic life. Unfortunately, this breathtaking display of colors coexists with less appealing but equally astonishing landscapes. The Atacama Desert harbors the largest accumulation of discarded clothing worldwide and the largest pools of lithium mining which require vast amounts of water for their production. Every year, approximately 56,000 tons of used clothing, predominantly consisting of fast fashion polyester products, water-intensive cotton fabrics, and equally polluting material scraps, are deposited, forming toxic mountains of waste. This article presents an interpretation of these distinct landscapes as interconnected realities of the dump that illustrate the impact of biocultural semiocides, whereby the loss of relationships and meanings with Earth materials is shaped by glocal forces. By making this argument, the article contends that the Atacama region replicates the conditions of the Earth as a global dumping and solastalgia, namely ‘the pain caused by the loss of solace and the sense of desolation connected to one´s home and territory.’.

An important shift is taking place in social cognition research, away from a focus on the individual mind and toward embodied and participatory aspects of social understanding. Empirical results already imply that social cognition is not reducible to the workings of individual cognitive mechanisms. To galvanize this interactive turn, we provide an operational definition of social interaction and distinguish the different explanatory roles – contextual, enabling and constitutive – it can play in social cognition. We show that interactive processes are (...) more than a context for social cognition: they can complement and even replace individual mechanisms. This new explanatory power of social interaction can push the field forward by expanding the possibilities of scientific explanation beyond the individual. (shrink)

Current theories of social cognition are mainly based on a representationalist view. Moreover, they focus on a rather sophisticated and limited aspect of understanding others, i.e. on how we predict and explain others’ behaviours through representing their mental states. Research into the ‘social brain’ has also favoured a third-person paradigm of social cognition as a passive observation of others’ behaviour, attributing it to an inferential, simulative or projective process in the individual brain. In this paper, we present a concept of (...) social understanding as an ongoing, dynamical process of participatory sense-making and mutual incorporation. This process may be described (1) from a dynamical agentive systems point of view as an interaction and coordination of two embodied agents; (2) from a phenomenological approach as a mutual incorporation, i.e. a process in which the lived bodies of both participants extend and form a common intercorporality. Intersubjectivity, it is argued, is not a solitary task of deciphering or simulating the movements of others but means entering a process of embodied interaction and generating common meaning through it. This approach will be further illustrated by an analysis of primary dyadic interaction in early childhood. (shrink)

In search of our highest capacities, cognitive scientists aim to explain things like mathematics, language, and planning. But are these really our most sophisticated forms of knowing? In this paper, I point to a different pinnacle of cognition. Our most sophisticated human knowing, I think, lies in how we engage with each other, in our relating. Cognitive science and philosophy of mind have largely ignored the ways of knowing at play here. At the same time, the emphasis on discrete, rational (...) knowing to the detriment of engaged, human knowing pervades societal practices and institutions, often with harmful effects on people and their relations. There are many reasons why we need a new, engaged—or even engaging—epistemology of human knowing. The enactive theory of participatory sense-making takes steps towards this, but it needs deepening. Kym Maclaren’s idea of letting be invites such a deepening. Characterizing knowing as a relationship of letting be provides a nuanced way to deal with the tensions between the knower’s being and the being of the known, as they meet in the process of knowing-and-being-known. This meeting of knower and known is not easy to understand. However, there is a mode of relating in which we know it well, and that is: in loving relationships. I propose to look at human knowing through the lens of loving. We then see that both knowing and loving are existential, dialectic ways in which concrete and particular beings engage with each other. (shrink)

Can we see the expressiveness of other people's gestures, hear the intentions in their voice, see the emotions in their posture? Traditional theories of social cognition still say we cannot because intentions and emotions for them are hidden away inside and we do not have direct access to them. Enactive theories still have no idea because they have so far mainly focused on perception of our physical world. We surmise, however, that the latter hold promise since, in trying to understand (...) cognition, enactive theory focuses on the embodied engagements of a cognizer with his world. In this paper, we attempt an answer for the question What is social perception in an enactive account? In enaction, perception is conceived as a skill, crucially involving action, an ability to work successfully within the set of regularities, or contingencies that characterize a given domain. If this is the case, then social perception should be a social skill. Having thus transformed the question of what social perception is into that of what social skill is, we examine the concept of social contingencies and the manner in which social skills structure—both constrain and empower— social interaction. Some of the implications of our account for how social and physical perception differ, the role of embodiment in social interaction and the distinction between our approach and other social contingency theories are also addressed.

In this paper, we introduce an enactive account of loving as participatory sense-making inspired by the “I love to you” of the feminist philosopher Luce Irigaray. Emancipating from the fusionist concept of romantic love, which understands love as unity, we conceptualise loving as an existential engagement in a dialectic of encounter, in continuous processes of becoming-in-relation. In these processes, desire acquires a certain prominence as the need to know (the other, the relation, oneself) more. We build on Irigaray’s account of (...) love to present a phenomenology of loving interactions and then our enactive account. Finally, we draw some implications for ethics. These concern language, difference, vulnerability, desire, and self-transformation. (shrink)

Pregnancy presents some interesting challenges for the philosophy of embodied cognition. Mother and fetus are generally considered to be passive during pregnancy, both individually and in their relation. In this paper, we use the enactive operational concepts of autonomy, agency, individuation, and participation to examine the relation between mother and fetus in utero. Based on biological, physiological, and phenomenological research, we explore the emergence of agentive capacities in embryo and fetus, as well as how maternal agency changes as pregnancy advances. (...) We show that qualitatively different kinds of agency have their beginnings already in utero, and to what extent fetal and maternal movement modulate affectivity and individuation in pregnancy. We thus propose that mother and fetus are both agents who participate in pregnancy. Pregnancy then emerges as a relational developmental organization that anchors and holds its developing participants. We end the paper with reflections on ethical implications of this proposal, and suggestions for future research. (shrink)

What does it take to see how autistic people participate in social interactions? And what does it take to support and invite more participation? Western medicine and cognitive science tend to think of autism mainly in terms of social and communicative deficits. But research shows that autistic people can interact with a skill and sophistication that are hard to see when starting from a deficit idea. Research also shows that not only autistic people, but also their non-autistic interaction partners can (...) have difficulties interacting with each other. To do justice to these findings, we need a different approach to autistic interactions—one that helps everyone see, invite, and support better participation. I introduce such an approach, based on the enactive theory of participatory sense-making and supported by insights from indigenous epistemologies. This approach helps counteract the homogenising tendencies of the “global mental health” movement, which attempts to erase rather than recognise difference, and often precludes respectful engagements. Based in the lived experiences of people in their socio-cultural-material and interactive contexts, I put forward an engaged—even engaging—epistemology for understanding how we interact across difference. From this perspective, we see participatory sense-making at work across the scientific, diagnostic, therapeutic, and everyday interactions of autistic and non-autistic people, and how everyone can invite and support more of it.

Is an individual agent constitutive of or constituted by its social interactions? This question is typically not asked in the cognitive sciences, so strong is the consensus that only individual agents have constitutive efficacy. In this article we challenge this methodological solipsism and argue that interindividual relations and social context do not simply arise from the behavior of individual agents, but themselves enable and shape the individual agents on which they depend. For this, we define the notion of autonomy as (...) both a characteristic of individual agents and of social interaction processes. We then propose a number of ways in which interactional autonomy can influence individuals. Then we discuss recent work in modeling on the one hand and psychological investigations on the other that support and illustrate this claim. Finally, we discuss some implications for research on social and individual agency. (shrink)

Underlying the recent focus on embodied and interactive aspects of social understanding are several intuitions about what roles the body, interaction processes, and interpersonal experience play. In this paper, we introduce a systematic, hands-on method for investigating the experience of interacting and its role in intersubjectivity. Special about this method is that it starts from the idea that researchers of social understanding are themselves one of the best tools for their own investigations. The method provides ways for researchers to calibrate (...) and to trust themselves as sophisticated instruments to help generate novel insights into human interactive experience. We present the basics of the method, and two empirical studies. The first is a video-study on autism, which shows greater refinement in the way people with autism embody their social interactions than previously thought. The second is a study of thinking in live interactions, which provides insight into the common feeling that too much thinking can hamper interaction, and into how this kind of interactional awkwardness might be unblocked.

What makes it possible to affect one another, to move and be moved by another person? Why do some of our encounters transform us? The experience of moving one another points to the inter-affective in intersubjectivity. Inter-affection is hard to account for under a cognitivist banner, and has not received much attention in embodied work on intersubjectivity. I propose that understanding inter-affection needs a combination of insights into self-affection, embodiment, and interaction processes. I start from Michel Henry's radically immanent idea (...) of self-affection, and bring it into a contrastive dialogue with the enactive concepts of autonomy and (participatory) sense-making. I suggest that the latter ideas can open up Henry's idea of self-affection to inter-affection (something he aimed to do, but did not quite manage) and that, in turn, Henry's work can provide insights into underexplored elements of intersubjectivity, such as its ineffable and mysterious aspects, and erotic encounters.

This paper combines a survey of existing literature in game-theoretic pragmatics with new models that fill some voids in that literature. We start with an overview of signaling games with a conflict of interest between sender and receiver, and show that the literature on such games can be classified into models with direct, costly, noisy and imprecise signals. We then argue that this same subdivision can be used to classify signaling games with common interests, where we fill some voids in (...) the literature. For each of the signaling games treated, we show how equilibrium-refinement arguments and evolutionary arguments can be interpreted in the light of pragmatic inference. (shrink)

In a paper from the late 1990s, Francisco Varela indicates that a science of inter-being is on the horizon. But how to envisage such a science? Here I propose that an enactive science of inter-being will benefit from engaging with recent innovative autism research that starts from autistic experience and intersubjectivity. Properly intersubjective autism research is both more ethically just and scientifically richer than cognitivist explanations that have dominated research, discourse, and practice for a long time, and which have tended (...) to set people apart more than connect them. I discuss the work of Bervoets and Hens (2020), who show how autism research is unavoidably theorethical, and must be in order to move past the catch-22 they identify between autism and dysfunction. This kind of research exemplifies a participatory sense-making between subjects and scientists, and it is here that 'steps to a science of inter-being' (Varela, 1999a) are being taken. (shrink)

Open peer commentary on the article “Going Beyond Theory: Constructivism and Empirical Phenomenology” by Urban Kordeš. Upshot: I propose that getting the empirical study of subjective experience off to a good start requires an intersubjective approach, in both theory and method, where intersubjectivity is understood not in the standard science way of verification by others, but rather as participation in the investigation of how experience transforms when examining it together. I argue that this will greatly help do justice to and (...) respect experience’s special transforming and transformative nature. (shrink)

English summary: Now that it has managed to become a science, history must remain the symposium theatre which allows us to converse with the dead. Our "connected" world delivers us up, defenceless, to the tyranny of every instant. History could be the antidote, inasmuch as it is a depository of people's collective experience. It lifts shadows up from the depth of the ages to make us share what we have learned from being who we are. We have undertaken a boundless (...) dialogue with the living. This book proposes to restore the dialogue with the dead by revisiting, through a succession of brief texts in the form of short essays and short stories, a number of episodes of universal history in an attempt to cull some lessons from it. At a time when history's progress has led to an excessive specialisation which has caused many scholars to withdraw into their ivory towers to enjoy, among experts, the fruit of their research, Michel De Jaeghere wants us to resume meditating on examples that have nourished human thought since ancient times.

Wat gebeurt er allemaal in relaties? We raken gefrustreerd wanneer een vriend niet terugbelt. We missen een geliefde die ver weg is. We komen elkaar tegen op straat. We vrijen. We voelen ons eenzaam. Soms terwijl we vrijen. We voelen ons diep met iemand verbonden. We verwachten veel. We doen ons best om niet te veel te verwachten. Soms lukt dat, en dan kunnen we elkaar echt ontmoeten.

This paper develops a model of persuasive demand inducement in the expert–client relationship. The expert frames the decision on whether or not to buy expert services faced by a client with prospect-theoretic preferences, by making the client see this decision from the perspective of a particular reference point. When inducing a client to buy risky curative services, the expert should set a high reference point, and frame all outcomes as losses. When instead inducing a client to buy safe preventive services, (...) as long as the client’s loss aversion is sufficiently high, the expert should set an intermediate reference point, framing high outcomes as gains and low outcomes as losses.

An important amount of research effort in psychology and neuroscience over the past decades has focused on the problem of social cognition. This problem is understood as how we figure out other minds, relying only on indirect manifestations of other people's intentional states, which are assumed to be hidden, private and internal. Research on this question has mostly investigated how individual cognitive mechanisms achieve this task. A shift in the internalist assumptions regarding intentional states has expanded the research focus with (...) hypotheses that explore the role of interactive phenomena and interpersonal histories and their implications for understanding individual cognitive processes. This interactive expansion of the conceptual and methodological toolkit for investigating social cognition, we now propose, can be followed by an expansion into wider and deeply-related research questions, beyond (but including) that of social cognition narrowly construed. Our social lives are populated by different kinds of cognitive and affective phenomena that are related to but not exhausted by the question of how we figure out other minds. These phenomena include acting and perceiving together, verbal and non-verbal engagement, experiences of (dis- )connection, management of relations in a group, joint meaning-making, intimacy, trust, conflict, negotiation, asymmetric relations, material mediation of social interaction, collective action, contextual engagement with socio-cultural norms, structures and roles, etc. These phenomena are often characterized by a strong participation by the cognitive agent in contrast with the spectatorial stance typical of social cognition research. We use the broader notion of embodied intersubjectivity to refer to this wider set of phenomena. This Research Topic aims to investigate relations between these different issues, to help lay strong foundations for a science of intersubjectivity - the social mind writ large. To contribute to this goal, we encouraged contributions in psychology, neuroscience, psychopathology, philosophy, and cognitive science that address this wider scope of intersubjectivity by extending the range of explanatory factors from purely individual to interactive, from observational to participatory"--Provided by publisher.

Enactive cognitive science combines questions in epistemology, ontology, and ethics by conceiving of bodies as open-ended and mutually transforming through activity. While enaction is not a theory of ethics, it can contribute to its foundations. We present a schematization of enactive ideas that underlie traditional distinctions between Being, Knowing, and Doing. Ethics in this scheme begins in the relation between knowing and becoming. Critical of dichotomous thinking, we approach the questions of alterity and ethical reality. Alterity is relevant to the (...) enactive approach, but not in the radical sense of transcendental arguments. We propose difference, instead, as a more generative concept. Following Simondon, we see norms and values manifest in webs of past and future acts together with their potentialities for becoming. We propose a transindividual concept of moral attunement that includes ethical know-how and consciousness raising. Through generative difference and attunement to configurations of becoming, enaction underpins an ethics of participation linking virtue ethics and ethics of care. (shrink)

The enactive approach to cognition distinctively emphasizes autonomy, adaptivity, agency, meaning, experience, and interaction. Taken together, these principles can provide the new sciences of language with a comprehensive philosophical framework: languaging as adaptive social sense-making. This is a refinement and advancement on Maturana’s idea of languaging as a manner of living. Overcoming limitations in Maturana’s initial formulation of languaging is one of three motivations for this paper. Another is to give a response to skeptics who challenge enactivism to connect “lower-level” (...) sense-making with “higher-order” sophisticated moves like those commonly ascribed to language. Our primary goal is to contribute a positive story developed from the enactive account of social cognition, participatory sense-making. This concept is put into play in two different philosophical models, which respectively chronicle the logical and ontogenetic development of languaging as a particular form of social agency. Languaging emerges from the interplay of coordination and exploration inherent in the primordial tensions of participatory sense-making between individual and interactive norms; it is a practice that transcends the self-other boundary and enables agents to regulate self and other as well as interaction couplings. Linguistic sense-makers are those who negotiate interactive and internalized ways of meta-regulating the moment-to-moment activities of living and cognizing. Sense-makers in enlanguaged environments incorporate sensitivities, roles, and powers into their unique yet intelligible linguistic bodies. We dissolve the problematic dichotomies of high/low, online/offline, and linguistic/nonlinguistic cognition, and we provide new boundary criteria for specifying languaging as a prevalent kind of human social sense-making.

A novel theoretical framework for an embodied, non-representational approach to language that extends and deepens enactive theory, bridging the gap between sensorimotor skills and language. -/- Linguistic Bodies offers a fully embodied and fully social treatment of human language without positing mental representations. The authors present the first coherent, overarching theory that connects dynamical explanations of action and perception with language. Arguing from the assumption of a deep continuity between life and mind, they show that this continuity extends to language. (...) Expanding and deepening enactive theory, they offer a constitutive account of language and the co-emergent phenomena of personhood, reflexivity, social normativity, and ideality. Language, they argue, is not something we add to a range of existing cognitive capacities but a new way of being embodied. Each of us is a linguistic body in a community of other linguistic bodies. The book describes three distinct yet entangled kinds of human embodiment, organic, sensorimotor, and intersubjective; it traces the emergence of linguistic sensitivities and introduces the novel concept of linguistic bodies; and it explores the implications of living as linguistic bodies in perpetual becoming, applying the concept of linguistic bodies to questions of language acquisition, parenting, autism, grammar, symbol, narrative, and gesture, and to such ethical concerns as microaggression, institutional speech, and pedagogy.

Prompted by our commentators, we take this response as an opportunity to clarify the premises, attitudes, and methods of our enactive approach to human languaging. We high-light the need to recognize that any investigation, particularly one into language, is always a concretely situated and self-grounding activity; our attitude as researchers is one of knowing as engagement with our subject matter. Our task, formulating the missing categories that can bridge embodied cognitive science with language research, requires avoiding premature abstractions and clarifying (...) the multiple circularities at play. Our chosen method is dialectical, which has prompted several interesting observations that we respond to, particularly with respect to what this method means for enactive epistemology and ontology. We also clarify the important question of how best to conceive of the variety of social skills we progressively identify with our method and are at play in human languaging. Are these skills socially constituted or just socially learned? The difference, again, leads to a clarification that acts, skills, actors, and interactions are to be conceived as co-emerging categories. We illustrate some of these points with a discussion of an example of aspects of the model at play in a study of gift giving in China.Keywords: Enactive epistemology, Enactive ontology, Dialectics, languaging, Shared know-how.

A fundamental fact about human minds is that they are never truly alone: all minds are steeped in situated interaction. That social interaction matters is recognized by any experimentalist who seeks to exclude its influence by studying individuals in isolation. On this view, interaction complicates cognition. Here, we explore the more radical stance that interaction co-constitutes cognition: that we benefit from looking beyond single minds toward cognition as a process involving interacting minds. All around the cognitive sciences, there are approaches (...) that put interaction center stage. Their diverse and pluralistic origins may obscure the fact that collectively, they harbor insights and methods that can respecify foundational assumptions and fuel novel interdisciplinary work. What might the cognitive sciences gain from stronger interactional foundations? This represents, we believe, one of the key questions for the future. Writing as a transdisciplinary collective assembled from across the classic cognitive science hexagon and beyond, we highlight the opportunity for a figure-ground reversal that puts interaction at the heart of cognition. The interactive stance is a way of seeing that deserves to be a key part of the conceptual toolkit of cognitive scientists. (shrink)

The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A (...) at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem. (shrink)
