The growth of the vein system of the leaf ofTropaeolum peltophorum was studied (i) at the vein level (analysis of the growth kinetics and of the growth field of the 7 primary veins) and (ii) at the limb level (comparison of the growth of the veins).The vein growth kinetics depend on the position of the vein on the leaf: there is a proximal/distal gradient and a bilateral gradient of the growth parameters (=variation of the temporal organization of the kinetics). The (...) growth field of the veins (=local growth pattern) is also dependent on time and on vein position. (shrink)

Does metacognition--the capacity to self-evaluate one's cognitive performance--derive from a mindreading capacity, or does it rely on informational processes? Joëlle Proust draws on psychology and neuroscience to defend the second claim. She argues that metacognition need not involve metarepresentations, and is essentially related to mental agency.

Granting that various mental events might form the antecedents of an action, what is the mental event that is the proximate cause of action? The present article reconsiders the methodology for addressing this question: Intention and its varieties cannot be properly analyzed if one ignores the evolutionary constraints that have shaped action itself, such as the trade-off between efficient timing and resources available, for a given stake. On the present proposal, three types of action, impulsive, routine and strategic, are designed (...) to satisfy the trade-off above when achieving goals of each type. While actions of the first two types depend on non-conceptual appraisals of a given intensity and valence, strategic intentions have a propositional format and guide action within longer-term executive frameworks involving prospective memory.

This chapter examines whether, and in what sense, one can speak of agentive mental events. An adequate characterization of mental acts should respond to three main worries. First, mental acts cannot have pre-specified goal contents. For example, one cannot prespecify the content of a judgment or of a deliberation. Second, mental acts seem to depend crucially on receptive attitudes. Third, it does not seem that intentions play any role in mental actions. Given these three constraints, mental and bodily actions appear (...) to have a significantly different structure. A careful analysis of the role of normative requirements, distinguishing them from instrumental reasons, allows the distinction between mental and bodily forms of action to be clarified. Two kinds of motives must be present for a mental act to develop. The first kind is instrumental: a mental act is performed because of some basic informational need, such as the need to "remember the name of that play". The second kind is normative: given the specific type of mental action performed, there is a specific epistemic norm relevant to that act. These two motives actually correspond to different phases of a single mental act. The first motivates the mental act, i.e. makes salient the corresponding goal. The second offers an evaluation of the feasibility of the act, on the basis of its constitutive normative requirement. Conceived in this way, a characterization of mental acts avoids the three difficulties mentioned above. The possibility of pre-specifying the outcome of epistemic mental acts is blocked by the fact that such acts are constituted by strict normative requirements. That mental acts include receptive features is shown to be a necessary architectural constraint for mental agents to be sensitive to epistemic requirements. Finally, the phenomenology of intending is shown to be absent in most mental acts; the motivational structure of mental acts is, rather, associated with error- signals and self-directed doubtings. Mental acts need to be recognized as a natural kind of action meant to normatively control and enhance cognitive efficiency according to current processing needs. (shrink)

The project of understanding rationality in non-human animals faces a number of conceptual and methodological difficulties. The present chapter defends the view that it is counterproductive to rely on the human folk psychological idiom in animal cognition studies. Instead, it approaches the subject on the basis of dynamic- evolutionary considerations. Concepts from control theory can be used to frame the problem in the most general terms. The specific selective pressures exerted on agents endowed with information-processing capacities are analysed. It is (...) hypothesized that metacognition offers an evolutionary stable response to the various demands of the internal and external flows of information in a competitive environment. Metacognition provides a form of process-reflexivity that can, but does not have to be redeployed through metarepresentations. Finally the claim that rationality so conceived involves normativity is discussed. (shrink)

This articles examines three ways in which the connection between semantic and pragmatic representations of a single action can be tightened up in order to remedy the puzzle of deviant causation. A first move consists in making the feedback process, i.e. the dynamics of the relationship between both representational components, a central element in the definition of an action. A second step brings in the action-effect principle, emphasizing the teleological relation of each pragmatic representation type with its external effects. A (...) final step consists in elucidating the constitutive character of demonstrative reference for the contents of working memory states. (shrink)

As part of their corporate social responsibility, many organizations practice cause-related marketing, in which organizations donate to a chosen cause with every consumer purchase. The extant literature has identified the importance of the fit between the organization and the nature of the cause in influencing corporate image, as well as the influence of a connection between the cause and consumer preferences on brand attitudes and brand choice. However, prior research has not addressed which cause composition most appeals to consumers or (...) the impact of cause choice on corporate image. A between-subjects field experiment in the Netherlands examines the influence of three core cause attributes—cause type, cause scope, and cause acuteness—on consumers’ perceptions of corporate image. Furthermore, this experiment examines the extent to which consumer identification with the cause mediates the influence of the cause attributes on corporate image. The findings indicate that identification with the cause leads to more positive evaluations of marketing campaigns for cause type and cause scope. Also, however, our results uncover a negative direct relationship between cause scope and corporate image. Cause acuteness is only marginally influential in corporate image perceptions. By proposing and testing a comprehensive model of the influence of cause attributes on corporate image in cause-related marketing, this article provides important implications and suggests avenues for further research.

A prominent but poorly understood domain of human agency is mental action, i.e., thecapacity for reaching specific desirable mental statesthrough an appropriate monitoring of one's own mentalprocesses. The present paper aims to define mentalacts, and to defend their explanatory role againsttwo objections. One is Gilbert Ryle's contention thatpostulating mental acts leads to an infinite regress.The other is a different although related difficulty,here called the access puzzle: How can the mindalready know how to act in order to reach somepredefined result? A (...) crucial element in the solutionof these puzzles consists in making explicit thecontingency between mental acts and mentaloperations, parallel to the contingency betweenphysical acts and bodily movements. The paper finallydiscusses the kind of reflexivity at stake in mentalacts; it is shown that the capacity to refer tooneself is not a necessary condition of the successfulexecution of mental acts.

In his interesting paper, Duca argues that even though people don't apply a logical rule of inference – contraposition- when they try to solve the Wason task, they may be using another kind of formal strategy in terms of probabilistic relations between the antecedent and the consequent. It is suggested that there are two ways of intepreting this task – one logical and apriori, the other hypothetical and data driven. Taking a probabilistic interpretation of the conditional rule for subjects' card (...) selections in the Wason task seems much more justified in this second reading. If this is true, new questions arise: how does a subject recognize which method is contextually appropriate, and what makes a solution contextually rational? (shrink)

Given disagreement about the architecture of the mind, the nature of self‐knowledge, and its epistemology, the question of how to understand the function and the scope of metacognition – the control of one’s cognition – is still a matter of hot debate. A dominant view, the self‐ascriptive view, has been that metacognition necessarily requires representing one’s own mental states as mental states, and, therefore, necessarily involves an ability to read one’s mind. The main claims of this view are articulated, and (...) the difficulties that they raise are discussed. An alternative view of metacognition, the ‘self‐evaluative view’, is then examined. It is argued that this view provides an account of metacognition that is both empirically and conceptually more adequate than the self‐ascriptive model. Particular attention is given to the problem of transferring self‐evaluative judgments to the case of others. (shrink)

Corporate crises call for effective communication to shelter or restore a company's reputation. The use of corporate social responsibility claims may provide an effective tool to counter the negative impact of a crisis, but knowledge about its effectiveness is scarce and lacking in studies that consider CSR communication during crises. To help fill this gap, this study investigates whether the length of company's involvement in CSR matters when it uses CSR claims in its crisis communication as a means to counter (...) negative publicity. The use of CSR claims in crisis communication is more effective for companies with a long CSR history than for those with a short CSR history, and consumer skepticism about claims lies at the heart of this phenomenon.

Perceiving an armchair prepares us to sit. Reading the first line in a text prepares us to read it. This article proposes that the affordance construct used to explain reactive potentiation of behavior similarly applies to reactive potentiation of cognitive actions. It defends furthermore that, in both cases, affordance-sensings do not only apply to selective (dis)engagement, but also to the revision and the termination of actions. In the first section, characteristics of environmental affordance-sensings such as directness, stability, action potentiation, valence, (...) and phenomenology are reexamined in light of contemporary cognitive science. In the second section, it is proposed that cognitive affordance-sensings can also be characterized along these dimensions. Called “metacognitive feelings” in the metacognitive literature, their function is to select, engage, revise and post-evaluate cognitive actions. A third section discusses alternative views, and responds to objections. (shrink)

Building on a model of the biological, socio-psychological, and structural drivers of luxury consumption, this article explores when and why luxury consumers consider ethics in their luxury consumption practices, to identify differences in their ethical and ethical luxury consumption. The variables proposed to explain these differences derive from biological, socio-psychological, and structural drivers, namely, consumers’ (1) age, (2) ethicality, (3) human values, (4) motivations, and (5) assumptive world. A cluster analysis of a sample of 706 U.S. adult luxury consumers reveals (...) five segments of luxury consumers, each reflecting a specific persona, that engage in both ethical and ethical luxury consumption to varying extents. The five segments differ in the extent to which they exhibit features related to four discriminant functions (immorality, ego-orientation, and strain; altruistic-orientation; conservation, in control, and positivity; and youth and luxury savvy), which vary across the biological, socio-psychological, and structural drivers. The findings thus indicate which segments of luxury consumers are most relevant for luxury firms pursuing a long-term sustainability agenda and suggest practical actions to reach those goals.

Hence, this book's provocative claim: today's so-called logical empiricism owes much more to Kant's notion of science than to Hume's.

This book chapter aims at exploring how intentional a piece of behavior should be to count as an action, and how a minimal view on action, not requiring a richly intentional causation, may still qualify such a behavior as voluntary.

Given disagreements about the architecture of the mind, the nature of self-knowledge, and its epistemology, the question of how to understand the function and scope of metacognition – the control of one's cognition - is still a matter of hot debate. A dominant view, the self-ascriptive view (or one-function view), has been that metacognition necessarily requires representing one's own mental states as mental states, and, therefore, necessarily involves an ability to read one's own mind. The self-evaluative view (or two-function view), (...) in contrast, takes metacognition to involve a procedural form of knowledge that is generated by actually engaging in a first-order cognitive task, and monitoring its success. The comparative and developmental arguments supporting, respectively, each of these views are discussed in the light of Hampton's operational definition of metacognition. New arguments are presented in favor of the two-function view. Recent behaviorial and neuroscientific evidence suggests that metacognitive assessment relies on dedicated implicit mechanisms, which are wholly independent, and indeed dissociable, from theory-based self-attribution. The two-function view is claimed to be the best interpretation of these findings. (shrink)

With rapidly spreading extractive practices on a global scale, the amount of residue generated raises the question of waste management and economic externalities. Are humans, and most crucially the Earth, equipped to welcome such an exponentially increasing quantity of restants? Artworks, as inexhaustible in their readings, are congenial to this idea of irreducible remains. In this paper, I argue Derrida’s treatment of remains might provide a waste-based approach to ecocriticism which, in turns, can be leveraged to articulate an insightful reading (...) of some artworks in times of extractive overconsumption and environmental destabilisation. Lee Bae’s Issu du feu (2000) and House of Moon (2014), Emerson Pontes’s Mil Quase Mortos: Boiúna, and Rochelle Goldberg’s Cannibal Actif (2018) are three contemporary artworks that directly challenge those externalities by explicitly engaging with remains ranging from charcoal, human-made waste and oil. Through a formal analysis of these artworks and a close reading of Derrida’s Feu la cendre, ‘Biodegradables Seven Diary Fragments,’ and the seminars Manger l’autre and Rhétorique du cannibalisme, it appears that eco-deconstruction is perhaps above all a matter of engaging with the structure of remains.

Dans le cadre des négociations commerciales internationales, les politiques en faveur de la diversité culturelle désignent un objectif qui consiste à limiter l'uniformisation censée résulter du fonctionnement du marché et du libre-échange. Depuis quelques années, le véritable débat ne porte plus sur l'objectif lui-même qui semble faire l'objet d'un consensus, mais sur les moyens d'y parvenir. Notre propos dans cet article est justement de revenir sur cet objectif en montrant sa complexité et son caractère multidimensionnel. Au-delà du discours incantatoire à (...) portée très générale sur ses bienfaits supposés, les décideurs publics doivent donc effectuer des arbitrages, classiquement en termes de coûts/bénéfices, de manière plus complexe entre les différentes dimensions de la diversité. Mener une politique en faveur de la diversité culturelle suppose donc de faire des choix parmi ces multiples aspects et d'assumer les coûts induits. (shrink)

Smoking remains the leading cause of preventable disease and death in the United States, killing approximately 480,000 people each year. This crushing health burden falls disproportionately, and recent CDC data shows that large disparities in adult cigarette smoking remain. One factor in these disparities is the use of flavors. Menthol cigarettes and other flavored tobacco products are used at higher rates by vulnerable populations including youth and young adults, African Americans, women, Hispanics and Asian Americans. This is no accident; the (...) tobacco industry has long targeted these same groups. Given FDA's failure to act to ban flavored tobacco products, states and municipalities are considering taking matters into their own hands to protect their communities from these dangerous products. The authors will explore state and local authority to restrict the sales of these products and review the evidence base indicating that removing flavored tobacco products – and menthol combustible products in particular - from the market would significantly reduce the toll of illness and death caused by these products.

This contribution aims to examine the dynamics that have emerged from a collaborative research-training approach having relied on collective interviews, in order to shed light on the growing phenomenon of the professional integration of foreign-trained teachers in Quebec schools which seems problematic in various aspects. A conversation analysis was used to identify how the expertises of a research culture and professional cultures come together to serve a knowledge co-production process that seems relevant by the two communities concerned. Three dynamics have (...) been identified : the development of a comprehensive posture, the production of new adjusted interpretations, and the affirmation of its actor’s competency. Their highlighting leads us to reflect on collaborative design and animation strategies that served the co-production of knowledge process. (shrink)

Against the prior view that primate communication is based only on signal decoding, comparative evidence suggests that primates are able, no less than humans, to intentionally perform or understand impulsive or habitual communicational actions with a structured evaluative nonconceptual content. These signals convey an affordance-sensing that immediately motivates conspecifics to act. Although humans have access to a strategic form of propositional communication adapted to teaching and persuasion, they share with nonhuman primates the capacity to communicate in impulsive or habitual ways. (...) They are also similarly able to monitor fluency, informativeness and relevance of messages or signals through nonconceptual cues. (shrink)

Granted that a given species is able to entertain beliefs and desires, i.e. to have (epistemic and motivational) internal states with semantically evaluable contents, one can raise the question of whether the species under investigation is, in addition, able to represent properties and events that are not only perceptual or physical, but mental, and use the latter to guide their actions, not only as reliable cues for achieving some output, but as mental cues (that is: whether it can 'read minds'). (...) The main aim of this article is to suggest that mindreading depends on two prior capacities : exercising simulation, as when one actively disengages from the present environment to imagine a counterfactual situation, and exploiting simulation, which implies that an imaginary situation is relocated within the real world. It is claimed that although apes have the first capacity, they don't have the second one, and therefore do not have access to mental attribution. (shrink)

Experience of agency in patients with schizophrenia involves an interesting dissociation; these patients demonstrate that one can have a thought or perform an action consciously without being conscious of thinking or acting as the motivated agent, author of that thought or of that action. This chapter examines several interesting accounts of this dissociation, and aims at showing how they can be generalized to thought insertion phenomena. It is argued that control theory allows such a generalization; three different comparators need to (...) be distinguished: the sense of subjectivity relies on a comparator in which motivation and emotion play a structuring role. The sense of agency emerges in a system that delivers a rough categorization of self-generated – versus other- generated – actions and mental activities. A third system specializes in the social evaluation of the effects of an action, intention or other thought process, given certain goals in self or in others. (shrink)

Against the view that metacognition is a capacity that parallels theory of mind, it is argued that metacognition need involve neither metarepresentation nor semantic forms of reflexivity, but only process-reflexivity, through which a task-specific system monitors its own internal feedback by using quantitative cues. Metacognitive activities, however, may be redescribed in metarepresentational, mentalistic terms in species endowed with a theory of mind.

What is a person, and how can a person come to know that she is a person identical to herself over time ? The article defends the view that the sense of being oneself in this sense consists in the ability to consciously affect oneself : in the memory of having affected oneself, joint to the consciousness of being able to affect oneself again. In other words, being a self requires a capacity for metacognition (control and monitoring of one's own (...) internal states). This view is compatible with the hypothesis that the self is a dynamic representation emerging out of a higher level control system, - valuation control - whose articulation with control of plans and perceptual/motor control is discussed in the context of normal and pertrubed agency.

And second, that even if (...) the Rule were to be acceptable, it should not lead one to reject religious belief. (shrink)

This paper defends the view that knowledge about one's own intentions can be gained in part through perception, although not through introspection.
