Living things can be classified by taxonomic similarity (lions and lynx), or shared ecological habitat (ducks and turtles). The present studies used card-sorting and triad tasks to explore developmental and experiential changes in conceptual flexibility–the ability to switch between taxonomic and ecological construals of living things–as well as two processes underlying conceptual flexibility: salience (i.e., the ease with which relations come to mind outside of contextual influences) and availability (i.e., the presence of relations in one’s mental (...) space) of taxonomic and ecological relations. We were also interested in the extent to which salience and availability of taxonomic and ecological relations predicted inductive inferences. Participants were 452 six to ten-year-olds from urban, suburban, and rural communities in New England. Across two studies, taxonomic relations were overwhelmingly more salient than ecological relations, although salience of ecological relations was higher among children from rural environments (Study 1) and those who engaged in unstructured exploration of nature (Study 2). Availability of ecological relations, as well as conceptual flexibility, increased with age, and was higher among children living in more rural environments. Notably, salience, but not availability, of ecological relations predicted ecological inferences. These findings suggest that taxonomic relations are a default way to organize intuitive biological knowledge and that environmental richness and relevant experience contribute to the salience and availability of ecological knowledge, and thereby, conceptual flexibility in biological thinking. More generally, they highlight important linkages between domain-specific knowledge and domain-general cognitive abilities. (shrink)

Neurons repeatedly exposed to similar perceptual experiences fire together and wire together to form ‘meaning kernels’ of concepts. Pulvermueller argues that abstract concepts may be devoid of meaning kernels, because the perceptual experiences that construct abstract concepts are subject to great variation and share few common features. Abstract concept are therefore grounded in the brain through features that belong to ‘meaning halos’, rather than to ‘meaning kernels’.

Flexibility in conceptual projection constitutes one of the most challenging issues in the embodiment and conceptual metaphor literatures. We sketch a theoretical proposal that places the burden of the explanation on attentional dynamics in interaction with mental models in working memory that are constrained to be maximally coherent. A test of this theory is provided in the context of the conceptual projection of time onto the domain of space. Participants categorized words presented at different spatial locations (...) (back–front, left–right) as referring to the past or to the future. Responses were faster when the irrelevant word location was congruent with the back–past, front–future metaphoric mapping. Moreover, when a new highly task-relevant spatial frame of reference was introduced, it changed the projection of past and future onto space in a way that was congruent with the new frame (past was now projected to left space and future to right space), as predicted by the theory. This study shows that there is substantial flexibility in conceptual projection and opens a venue to study metaphoric variation across tasks, individuals, and cultures as the result of attentional dynamics.

Observations have been made about branding’s shift from a material to conceptual focus. Consequently, corporate branding has become more focused on associating and imbuing corporate brands with supposedly positive values and attributes. This article locates this emphasis in the context of Singapore’s marketized higher education sector, and examines how conceptual values like flexibility, freedom and empowerment are expressed linguistically and, more significantly, symbolized in and through photographic images in corporate brand communication. It is argued that while the (...) circulation of conceptual values in branding has arisen in part due to the imperatives of branding, the privileging of values like flexibility, freedom and empowerment is symptomatic of neoliberal capitalist influence and the subjection of higher education in Singapore to a knowledge-based economic logic. This helps to shape stakeholders’ concepts and expectations of higher education as well as public attitudes towards the neoliberal knowledge-based market system more broadly. (shrink)

According to embodied theories of language (ETLs), word meaning relies on sensorimotor brain areas, generally dedicated to acting and perceiving in the real world. More specifically, words denoting actions are postulated to make use of neural motor areas, while words denoting visual properties draw on the resources of visual brain areas. Therefore, there is a direct correspondence between word meaning and the experience a listener has had with a word's referent on the brain level. Behavioral and neuroimaging studies have provided (...) evidence in favor of ETLs; however, recent studies have also shown that sensorimotor information is recruited in a flexible manner during language comprehension (e.g., Raposo et al. ; Van Dam et al., ), leaving open the question as to what level of language processing sensorimotor activations contribute. In this study, we investigated the time course of modality‐specific contributions (i.e., the contribution of action information) as to word processing by manipulating both (a) the linguistic and (b) the action context in which target words were presented. Our results demonstrate that processes reflecting sensorimotor information play a role early in word processing (i.e., within 200 ms of word presentation), but that they are sensitive to the linguistic context in which a word is presented. In other words, when sensorimotor information is activated, it is activated quickly; however, specific words do not reliably activate a consistent sensorimotor pattern. (shrink)

Abstract. The aim of this paper is to present a topological method for constructing discretizations (tessellations) of conceptual spaces. The method works for a class of topological spaces that the Russian mathematician Pavel Alexandroff defined more than 80 years ago. Alexandroff spaces, as they are called today, have many interesting properties that distinguish them from other topological spaces. In particular, they exhibit a 1-1 correspondence between their specialization orders and their topological structures. Recently, a special type of Alexandroff spaces (...) was used by Ian Rumfitt to elucidate the logic of vague concepts in a new way. According to his approach, conceptual spaces such as the color spectrum give rise to classical systems of concepts that have the structure of atomic Boolean algebras. More precisely, concepts are represented as regular open regions of an underlying conceptual space endowed with a topological structure. Something is subsumed under a concept iff it is represented by an element of the conceptual space that is maximally close to the prototypical element p that defines that concept. This topological representation of concepts comes along with a representation of the familiar logical connectives of Aristotelian syllogistics in terms of natural settheoretical operations that characterize regular open interpretations of classical Boolean propositional logic. In the last 20 years, conceptual spaces have become a popular tool of dealing with a variety of problems in the fields of cognitive psychology, artificial intelligence, linguistics and philosophy, mainly due to the work of Peter Gärdenfors and his collaborators. By using prototypes and metrics of similarity spaces, one obtains geometrical discretizations of conceptual spaces by so-called Voronoi tessellations. These tessellations are extensionally equivalent to topological tessellations that can be constructed for Alexandroff spaces. Thereby, Rumfitt’s and Gärdenfors’s constructions turn out to be special cases of an approach that works for a more general class of spaces, namely, for weakly scattered Alexandroff spaces. This class of spaces provides a convenient framework for conceptual spaces as used in epistemology and related disciplines in general. Alexandroff spaces are useful for elucidating problems related to the logic of vague concepts, in particular they offer a solution of the Sorites paradox (Rumfitt). Further, they provide a semantics for the logic of clearness (Bobzien) that overcomes certain problems of the concept of higher2 order vagueness. Moreover, these spaces help find a natural place for classical syllogistics in the framework of conceptual spaces. The crucial role of order theory for Alexandroff spaces can be used to refine the all-or-nothing distinction between prototypical and nonprototypical stimuli in favor of a more fine-grained gradual distinction between more-orless prototypical elements of conceptual spaces. The greater conceptual flexibility of the topological approach helps avoid some inherent inadequacies of the geometrical approach, for instance, the so-called “thickness problem” (Douven et al.) and problems of selecting a unique metric for similarity spaces. Finally, it is shown that only the Alexandroff account can deal with an issue that is gaining more and more importance for the theory of conceptual spaces, namely, the role that digital conceptual spaces play in the area of artificial intelligence, computer science and related disciplines. Keywords: Conceptual Spaces, Polar Spaces, Alexandroff Spaces, Prototypes, Topological Tessellations, Voronoi Tessellations, Digital Topology. (shrink)

I strongly agree with the criticisms of the restrictive isomorphic matching definition of empathy made by Murphy, Lilienfeld, and Algoe, and largely agree with their conceptualization of empathy as a dynamic process best defined by its function. In this commentary, I extend this argument by emphasizing the relational, interpersonal aspects of empathy. It is my view that in order to understand the functions of empathy, we must take into account not only the internal experience of the individual empathizing, but also (...) the individual whose perspective the empathizer is attempting to take. I highlight how the emotional needs of others are dynamic and require flexible adaptation and underscore the role of context in appreciating the function of empathy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:258 Feminist Studies 47, no. 2. © 2021 by Feminist Studies, Inc. Mei-Hua Chen and Hong-zen Wang Flexible Intimacies in the Global Intimate Economy: Evidence from Taiwan’s Cross-Border Marriages When Lin Ping was interviewed by the first author of this article at a detention center in the southern city of Tainan, Taiwan, in September 2006, she was forty-three. At that time, she had been married to a Taiwanese man (...) for five years and had successfully obtained a permit for employment at a factory, earning NT$27,000 a month for working ten hours a day. However, before having obtained the work permit, Lin managed to find jobs in informal sectors as a cleaner, a care worker, and a stall vendor’s helper, earning NT$15,000 a month. By the time of our interview, Lin had gone to work at a brothel because she could not put up with her husband anymore. Lin’s husband is twenty years older than she is and, as she described their relationship, the huge age gap makes communication between the couple difficult. They fought often and fiercely. During those fights, Lin’s husband would threaten to divorce her and to not renew her application for residency, which would result in her immediate deportation to China. This did happen once when Lin’s husband refused to renew her work permit. As a result, Lin overstayed her visa and lost her job at the factory. Being thus unemployed, Lin had to dip into her savings and risked going into debt. Her dire financial situation caused her anxiety. Losing the regular income provided by her factory job meant not only having nothing to live on but also being unable to send money back home to China. Given that her marriage failed to provide her the work permit she needed, Lin wanted to leave her husband Mei-Hua Chen and Hong-zen Wang 259 and “go out” for her own good. When asked what she thinks of the stigma attached to commercial sex, Lin replied, “I need to be able to feed myself first. But if you don’t have a work permit and a job, it [sex work] is the only way out. So, I thought I would do it.” She continued: “Once I had the money, I would be able to run a small business such as a noodle stall or selling steam dumplings.” Lin Ping’s stories serve to sketch out the interconnectedness between cross-border sex work and cross-border marriage. As her experiences show, cross-border sex work and marriage tend to overlap in certain spheres; however, they are more often than not conceptualized as two separate institutions. Both are grouped under already dichotomized migratory categories such as marriage migrants and economic migrants, real marriage and fake marriage, legal workers and workers without permits, and legal and illegal migrants, etc. Such dichotomization downplays the fact that many marriage migrants, like economic migrants, invest great economic interests in cross-border marriages; it also downplays the fact that migrant sex workers might also be involved in having intimate relationships with someone. Apart from the entanglement of monetary exchange and intimacy, cross-border marriage and cross-border sex work are also parts of a global intimate economy in which the Global North appropriates southern women’s reproductive and intimate labor. Seen in this light, it becomes urgent to theorize how women from the South manage to survive in the global intimate economy by shifting between cross-border marriage and cross-border sex work in the North. Admittedly, such a Global North-and-South framework fits awkwardly when it comes to understanding Taiwan’s situation because economic development is the sole barometer used to define the North and the South, and economically, Taiwan should be in the North camp. Politically, however, due to the majority of nations not recognizing its sovereignty, Taiwan is much more peripheral than most southern countries, let alone China. Therefore, compared to countries in Southeast Asia, Taiwan is economically North but politically South. This semi-peripheral position in the North-South framework, in our view, makes Taiwan a unique case to theorize the global intimate economy. As a tactic... (shrink)

A novel conceptual framework is introduced for the Complexity Levels Theory in a Categorical Ontology of Space and Time. This conceptual and formal construction is intended for ontological studies of Emergent Biosystems, Super-complex Dynamics, Evolution and Human Consciousness. A claim is defended concerning the universal representation of an item’s essence in categorical terms. As an essential example, relational structures of living organisms are well represented by applying the important categorical concept of natural transformations to biomolecular reactions and relational (...) structures that emerge from the latter in living systems. Thus, several relational theories of living systems can be represented by natural transformations of organismic, relational structures. The ascent of man and other living organisms through adaptation, is viewed in novel categorical terms, such as variable biogroupoid representations of evolving species. Such precise but flexible evolutionary concepts will allow the further development of the unifying theme of local-to-global approaches to highly complex systems in order to represent novel patterns of relations that emerge in super- and ultra-complex systems in terms of compositions of local procedures. Solutions to such local-to-global problems in highly complex systems with ‘broken symmetry’ might be possible to be reached with the help of higher homotopy theorems in algebraic topology such as the generalized van Kampen theorems (HHvKT). Categories of many-valued, Łukasiewicz-Moisil (LM) logic algebras provide useful concepts for representing the intrinsic dynamic ‘asymmetry’ of genetic networks in organismic development and evolution, as well as to derive novel results for (non-commutative) Quantum Logics. Furthermore, as recently pointed out by Baianu and Poli (Theory and applications of ontology, vol 1. Springer, Berlin, in press), LM-logic algebras may also provide the appropriate framework for future developments of the ontological theory of levels with its complex/entangled/intertwined ramifications in psychology, sociology and ecology. As shown in the preceding two papers in this issue, a paradigm shift towards non-commutative, or non-Abelian, theories of highly complex dynamics—which is presently unfolding in physics, mathematics, life and cognitive sciences—may be implemented through realizations of higher dimensional algebras in neurosciences and psychology, as well as in human genomics, bioinformatics and interactomics.

The current study is a conceptual replication of Wang using a pretest-posttest design and an online sample through Amazon’s Mechanical Turk. Seventy-one Asian-Americans recalled a recent memory before and after being primed as either Asian or American. On pre-prime memories, conditions did not significantly differ. However, on post-prime memories, participants primed as American recalled more self-focused memories than relationally focused memories and those primed as Asian recalled more relationally focused memories than self-focused memories. In addition, memories of Asian-Americans primed (...) as American consisted of a smaller proportion of social interaction instances than those primed as Asian. In total, 6 of the 8 effects found in Wang were replicated. We discuss the implications that the current results and past studies have on our understanding of how culture influences memory encoding and retrieval. (shrink)

Coping flexibility, as defined by the dual-process theory, refers to one’s ability to relinquish a coping strategy recognized as ineffective—abandonment—and to devise and implement an alternative and more effective strategy—re-coping. The coping flexibility hypothesis dictates that richer coping flexibility produces more adaptive outcomes caused by stress responses, such as reduced psychological and physical dysfunction. We tested the reliability and validity of the Coping Flexibility Scale-Revised and the CFH using the CFS-R, which was developed to measure coping (...) flexibility. In total, we performed three studies involving 6,752 participants. Study 1 provided the psychometric properties of the CFS-R and tested this factorial structure by a confirmatory factor analysis. Study 2 estimated the validity of the CFS-R by examining the associations between its three subscales and variables that were conceptually similar to them. Study 3 tested the CFH using a longitudinal design after controlling for the effects of typical coping strategies and other types of coping flexibility. Overall, the CFH was supported by the use of the CFS-R, and the findings in Studies 2 and 3 showed that it had acceptable validity and reliability. Our findings implied that abandonment and re-coping can predict reduced depressive symptoms more than other types of theoretical framings for coping flexibility. Additionally, a meta-analysis of the Cronbach’s alphas for all samples in this study showed that they were 0.87 for abandonment, 0.92 for re-coping, and 0.86 for meta-coping. (shrink)

Conceptual features differ in how mentally tranformable they are. A robin that does not eat is harder to imagine than a robin that does not chirp. We argue that features are immutable to the extent that they are central in a network of dependency relations. The immutability of a feature reflects how much the internal structure of a concept depends on that feature; i.e., how much the feature contributes to the concept's coherence. Complementarily, mutability reflects the aspects in which (...) a concept is flexible. We show that features can be reliably ordered according to their mutability using tasks that require people to conceive of objects missing a feature, and that mutability (conceptual centrality) can be distinguished from category centrality and from diagnosticity and salience. We test a model of mutability based on asymmetric, unlabeled, pairwise dependency relations. With no free parameters, the model provides reasonable fits to data. Qualitative tests of the model show that mutability judgments are unaffected by the type of dependency relation and that dependency structure influences judgments of variability. (shrink)

A growing body of evidence suggests that cognition is embodied and grounded. Abstract concepts, though, remain a significant theoretical chal- lenge. A number of researchers have proposed that language makes an important contribution to our capacity to acquire and employ concepts, particularly abstract ones. In this essay, I critically examine this suggestion and ultimately defend a version of it. I argue that a successful account of how language augments cognition should emphasize its symbolic properties and incorporate a view of embodiment (...) that recognizes the flexible, multi- modal and task-related nature of action, emotion and perception systems. On this view, language is an ontogenetically disruptive cognitive technology that expands our conceptual reach. (shrink)

Section R1 clarifies and elaborates this main thesis, responding to a number of objections and misunderstandings. Section R2 considers three contrasting accounts of the mechanism of (...) intermodular integration. Section R3 discusses objections to some of the empirical data supporting my main thesis. Section R4 criticizes some competing theories of the role of language in cognition. And section R5 considers some proposed supplementary cognitive roles that language might play. (shrink)

Building a flexible supply chain can enable the firms to manage their supply chains to adapt effectively to dynamic market demand changes and thus guarantee their accelerated growth in the future. In this vein, this study aims to address several important issues in supply chain management by considering two characteristics of blockchain technology and exploring the specific conditions under which firms are likely to develop trust in supply chain management. Furthermore, we argue that such supply chain trust is vital to (...) the success of achieving and increasing supply chain flexibility. In addition, we propose that top management teams’ digital leadership within the firms plays a vital role in moderating the contribution of each dimension of blockchain technology to supply chain trust. Using data from a large sample of 338 firms in China, we perform structural equation modeling to examine our conceptual framework empirically. Our results highlight and support the idea that blockchain technology’s information transparency and security influence the trust-building in a supply chain and supply chain flexibility and articulate the particular importance of digital leadership in explaining the contribution of different blockchain technology characteristics to trust-building. Our study advances the theoretical, empirical, and managerial analysis of critical factors to build trust and achieve flexibility in supply chains. (shrink)

Humans think and communicate in very flexible and schematic ways, and a Spatial Data Infrastructure (SDI) for the Amazon and associated information system ontologies should reflect this flexibility and the adaptive nature of human cognition in order to achieve semantic interoperability. In this paper I offer a conceptual investigation of SDI and explore the nature of cultural schemas as expressions of indigenous ontologies and the challenges of semantic interoperability across cultures. Cultural schemas are, in essence, our ontologies, but (...) they are markedly different than classical formal ontologies. They shape our ontological commitments to what exists in the world as well as the ways in which we approach and engage the world. And while they help structure our understanding of the world in which we are embedded, they are associative and flexible. They help to focus our attention to particular details of our experiences and give them salience, yet they cannot be simply reduced to a series of extracted features. They allow us to make meaning of the contextualized, cultural experience in which we are always immersed. An SDI is a shared social-technological-informational structure that, if it is to be useful and successful for sustainability in the Amazon, must incorporate and use indigenous cultural schemas. Indigenous communities must have the ability to contribute to the collection of geospatial data and their contributions recognized as legitimate forms of knowledge. In order for the SDI to work, it must recognize the larger cultural landscape to which cultural schemas can connect to the ready-to-hand elements of salient cultural experiences. (shrink)

The majority of – usually moral – problems inherent in elite sport, such as whether athletes should be able to take particular drugs, wear particular clothing, or utilise particular tools, arguably stem from a conceptual one based on faulty logic and competing values. Sport is a human enterprise that represents a multitude of human compulsions, desires and needs; the urge to be competitive, to co-operate, to excel, to develop, to play, to love and be loved, and to find meaning (...) in one's existence. From the perspective of an amateur athlete, this pluralism is possible. When one is involved in athletics at the lower echelons, the values that one holds in relation to sport are fluid and flexible; they are prioritised according to a myriad of other influences that are contingent to a particular situation. As such, the reasons that the general population participate in athletic activities and the values they consequently ascribe to it are complex and wide-ranging and thus fall into the sociological realm. The philosophical problem with value in sport is found at the highest level, the professional platform, where discordant values are espoused, particularly the value of ever increasing quantifiable performance. The athletic events at the Olympic Games are the archetypal manifestation of this Citius , Altius , Fortius aphorism and yet when taken to its logical conclusion becomes evidently absurd. (shrink)

There are several important criticisms against the unificationist model of scientific explanation: Unification is a broad and heterogeneous notion and it is hard to see how a model of explanation based exclusively on unification can make a distinction between genuine explanatory unification from cases of ordering or classification. Unification alone cannot solve the asymmetry and irrelevance problems. Unification and explanation pull in different directions and should be decoupled, because for good scientific explanation extra ad explanandum information is often required. I (...) am presenting a possible solution to those problems, by focusing on an often overlooked but important element of how theoretic unification is achieved—the conceptual frameworks of theories. The core conceptual assumptions behind theories are decisive for discriminating between explanatory and non-explanatory unification. The conceptual framework is also flexible enough to balance the tension between informativeness and maximum systematization in constructing explanatory inferences. A short case study of orthogenetic and Darwinian explanations in paleontology is presented as an illustration of how my addition to the unificationist model is applicable to a historical debate between rival explanations.

This article reconstructs the normative strategy of interpretation of Martin Heidegger’s Being and Time in modern analytical philosophy, and also proposes a theoretical framework for understanding this strategy as a historical phenomenon. The article describes the development of the normative direction in the interpretation of Heidegger’s fundamental ontology. Its first branch—the socio-normative, or the neopragmatist one—is associated with such philosophers as John Haugeland and Robert Brandom. The second one—the ethico-normative, or postneopragmatist one—branch is represented by Steven Crowell and Sacha Golob. (...) It is shown that the first group of normativists focused mainly on implicit social norms and structures of conformity, while the second—focuses primarily on Kantian ethics and Christina Korsgaard’s interpretation of Kant, as well as on the inferentialist philosophy of language of Robert Brandom. The conceptual schemes used by each of the representatives of these approaches are reconstructed. The connections of different approaches within the framework of the normative direction with each other are shown. The concept of a relay race is proposed, which can describe normative Heideggerianism as a historical phenomenon. It is shown that the development of normative Heideggerianism can be characterized as theoretical progress in relation to the accuracy of the interpretation of Heidegger’s texts. The grounds for the comparative “progressiveness” of different normative approaches in the updates of the basic normative conceptual scheme that they involve are clarified. It is also shown that the progress of the normative conceptual scheme in the direction of flexibility and adaptation to Heidegger’s text is fraught with a loss of meaningfulness of the very concept of norm. It is argued that the concept of norm, despite the loss of its empirical content, can be used to translate Heidegger’s concepts for pragmatic reasons. (shrink)

Multiple versions of the Chinese Remote Associates Test have been developed. Thus far, all CRATs have employed verbal stimuli; other forms of stimuli have not yet been used. In this context, the present study compiled a Chinese Visual Remote Associates Test that conforms to the Chinese language and culture based on a picture naming database. The developed CVRAT has two versions, CVRAT-A and CVRAT-B, each comprising 20 test questions. A typical CVRAT question consists of three stimuli pictures, requiring respondents to (...) propose a target word that is semantically associated with all the pictures. When compiling the CVRAT, this study first selected target words, sifted through stimuli words and corresponding pictures, and analyzed pilot test questions. After compilation, their reliability and validity were examined. The results showed that the CVRAT had moderate internal consistency reliability, good criterion-related validity for the Chinese Word Remote Associates Test, Chinese Radical Remote Associates Test, Chinese Compound Remote Associates Test, insight problem-solving, as well as acceptable discriminant validity for fluency, flexibility, and originality of a divergent thinking test. In other words, CVRAT can effectively measure remote associative capability and provides a figural creativity test that facilitates the understanding of different kinds of remote associations.

We are already witnessing the emergence of a new economic paradigm - the sharing economy - that will radical transform way of life of society. The new economic paradigm is based on the values of a post-modern society - the imperative of sustainable development models, the growth of meaningful consumption and the development of new types of solidarity. The diversity of business and non-profit sharing services is a result of the growing areas of the sharing economy, the improvement of the (...) technological infrastructure. The sharing economy takes place in organized systems or networks, in which participants conduct sharing activities in the form of renting, lending, trading, bartering, donation and swapping of different physical and non-material resources. The sharing economy framework is an "umbrella" concept. This approach generates not only problems, but has benefits. "Flexible" methodologies that focus on the process of changing sharing practices provide great opportunities for understanding current socio-economic changes and making trustworthy forecasts. Global and country-specific factors determinate the development of sharing projects. Specific factors can include specific tax regimes; expansion of foreign digital platforms that popularize the culture of sharing, socio-cultural practices of non-market exchanges that have developed in countries, which are easily transferred and scaled from an offline to an online, etc. Russian authorities provide the best competitive conditions for sharing services, increase participants' trust, provide information support and promotion. The lack of state support for some sharing sector leads to a slower its development. (shrink)

The evolution of a relevant nosological concept reflects changes in the distinction between what is recognized and defined as normal and pathologic. Attention is directed to the rationale and value of detecting subclinical aging-related modifications in cognitive performance. The position that different kinds of dementias may have precedents in etiological-specific kinds of early or mild cognitive impairments (MCI) supports targeting people earlier for study of these subclinical symptoms. Because heterogeneous disorders can be expected to have multiple patterns of cognitive and (...) behavioral changes, useful conceptual nosologies should be flexible. Yet clinical research primarily restricts its focus to a single pathway where MCI leads to Alzheimer's disease (AD), and uses selective recruitment, washout screenings, repeated trialing of similar compounds, and other methods that bank the published evidence in favor of the existing therapies and their modest efficacy. This focus on AD recursively colors MCI, not as a flexible "human kind" in need of more careful research, but like AD, as an essential "natural kind." Early determination of MCI targets a potential pharmaceutical market of a quarter to a half of the population over sixty-five and the individual experiencing cognitive decline in its early stages is aware and sensitive to their surroundings, to a linked sociodegeneration with neurodegeneration. This paper examines how classifying people changes both the classifier and the subject of classification. The potential for conflict of interest is raised regarding what new causal knowledge and techniques for ascertainment are selected. Reading evidence from epidemiology, neurology, and clinical studies through science studies and bioethics lenses, we explore the possibility of a pluralistic model of cognitive impairment nosology where biological/pathologic processes respond and interrelate with a normal healthy state.

Psychological research on emotion perception anchors heavily on an object perception analogy. We present static “cues,” such as facial expressions, as objects for perceivers to categorize. Yet in the real world, emotions play out as dynamic multidimensional events. Current theoretical approaches and research methods are limited in their ability to capture this complexity. We draw on insights from a predictive coding account of neural activity and a grounded cognition account of concept representation to conceive of emotion perception as a stream (...) of synchronized conceptualizations between two individuals, which is supported and shaped by language. We articulate how this framework can illuminate the fundamental need to study culture, as well as other sources of conceptual variation, in unpacking conceptual synchrony in emotion. We close by suggesting that the conceptual system provides the necessary flexibility to overcome gaps in emotional synchrony. (shrink)

Nicholas Rescher’s work can be deemed as the most serious endeavor at both reviving the idealist perspective within contemporary analytic philosophy and making it compatible with a scientifically oriented outlook on reality. It can be argued, however, that Rescher’s conceptual idealism cannot be defined as a “true” idealism because, while adopting an idealist stance at the epistemological level, he nevertheless endorses a clear realist position at the ontological one, and this means that a non-dogmatic realism can actually be compatible (...) with his position. Furthermore, his particular brand of idealism gives rise to a rather flexible system, which can face criticisms without giving up its basic premises. In the present paper I would like to clarify—and possibly deepen—these remarks taking into account, besides two Rescher’s well-known volumes on conceptual idealism and scientific realism, a more recent paper of his also devoted to the theme of conceptual idealism. I believe in fact that the issues raised by Rescher in these works are fundamental for both a correct understanding of the current realism/anti-realism debate in metaphysics and the philosophy of science, and for the clarification as well of the manifest “idealistic turn” that took place within analytic philosophy in the last few decades.

The paper critically discusses the Chalmers-and-Jackson strategy of accounting for the dynamics of conceptual intuitions. In contrast to this strategy, it is argued that concepts alone do not determine in advance rational responses to new evidence. An initial concept is often revised in the light of new data, the revision being guided by the goal of detecting the deep causal structure of the domain investigated. Using examples from the history of science (concept REFLEX ARC) as an illustration, it is (...) argued that the dilemma of either irrational messy updating of intuitions (Yablo) or strict rails of conceptual pre-determination (Chalmers-Jackson) is a false one. Rationality does not lie in the alleged conceptual apriority, but in the flexible pursuit of reasonable epistemic goals. (shrink)

We present a computer-supported approach for the logical analysis and conceptual explicitation of argumentative discourse. Computational hermeneutics harnesses recent progresses in automated reasoning for higher-order logics and aims at formalizing natural-language argumentative discourse using flexible combinations of expressive non-classical logics. In doing so, it allows us to render explicit the tacit conceptualizations implicit in argumentative discursive practices. Our approach operates on networks of structured arguments and is iterative and two-layered. At one layer we search for logically correct formalizations for (...) each of the individual arguments. At the next layer we select among those correct formalizations the ones which honor the argument’s dialectic role, i.e. attacking or supporting other arguments as intended. We operate at these two layers in parallel and continuously rate sentences’ formalizations by using, primarily, inferential adequacy criteria. An interpretive, logical theory will thus gradually evolve. This theory is composed of meaning postulates serving as explications for concepts playing a role in the analyzed arguments. Such a recursive, iterative approach to interpretation does justice to the inherent circularity of understanding: the whole is understood compositionally on the basis of its parts, while each part is understood only in the context of the whole. We summarily discuss previous work on exemplary applications of human-in-the-loop computational hermeneutics in metaphysical discourse. We also discuss some of the main challenges involved in fully-automating our approach. By sketching some design ideas and reviewing relevant technologies, we argue for the technological feasibility of a highly-automated computational hermeneutics. (shrink)

From the viewpoint of the constitutional crisis in Europe, slow UN reforms, difficulties implementing the Kyoto Protocol and the International Criminal Court, and tensions between human rights and trade, Mireille Delmas-Marty's 'journey through the legal landscape' of the early years of the 21st century shows it to be dominated by imprecision, uncertainty and instability. The early 21st century appears to be the era of great disorder: in the silence of the market and the fracas of arms, a world overly fragmented (...) by anarchical globalisation is being unified too quickly through hegemonic integration. How, she asks, can we move beyond the relative and the universal to build order without imposing it, to accept pluralism without giving up on a common law? Neither utopian fusion nor illusory autonomy, Ordering Pluralism is her answer: both an epistemological revolution and an art, it means creating a common legal area by progressive adjustments that preserve diversity. Since an immutable world order is impossible, the imaginative forces of law must be called upon to invent a flexible process of harmonisation that leaves room for believing we can agree on - and protect - common values. 'The book is timely and relevant to the practical concerns of those who work with, and within, the legal system. We must thank Professor Delmas-Marty for her fine work.' From the foreword, Stephen Breyer, Washington, DC. (shrink)

Both scientists and children make important structural discoveries, yet their computational underpinnings are not well understood. Structure discovery has previously been formalized as probabilistic inference about the right structural form—where form could be a tree, ring, chain, grid, etc.. Although this approach can learn intuitive organizations, including a tree for animals and a ring for the color circle, it assumes a strong inductive bias that considers only these particular forms, and each form is explicitly provided as initial knowledge. Here we (...) introduce a new computational model of how organizing structure can be discovered, utilizing a broad hypothesis space with a preference for sparse connectivity. Given that the inductive bias is more general, the model's initial knowledge shows little qualitative resemblance to some of the discoveries it supports. As a consequence, the model can also learn complex structures for domains that lack intuitive description, as well as predict human property induction judgments without explicit structural forms. By allowing form to emerge from sparsity, our approach clarifies how both the richness and flexibility of human conceptual organization can coexist. (shrink)

This paper proposes and develops the feelings of goals hypothesis (FGH). It has two aims: first, to describe the evolutionary function of emotional feelings (EFs), and second, to describe the content and the format of EFs. According to FGH, the evolutionary function of EFs is to enable motoric flexibility. Specifically, EFs are a component of a psychological mechanism that permits differential motoric reactions to the same stimulus. Further, according to FGH, EF is a special type of mental representation with (...) the content of an action goal, and with a non-motoric, non-conceptual format. This paper thoroughly clarifies the assumptions underlying FGH and discusses its theoretical implications and empirical predictions. (shrink)

The capacity for flexible niche construction increases suddenly and dramatically when discrete memories and sensorimotor associations become woven into an interconnected worldview. Ontogenetic learning is as vital to culture as social learning because it is the wellspring of cultural novelty. Human altruism may result from pressures exerted at the level of cultural rather than biological replicators.

This article presents the novel view that ‘inclusion into seclusion’ and ‘public disclosure of embarrassing facts’ (‘misuse of private information’ (“MOPI”) in the UK), which both the academic commentary and US case law treat as two separate legal actions, occupy the same conceptual space. This claim has important practical ramifications. No further development of the law is required to realise an actionable intrusion tort as part of the UK’s MOPI tort. The argument is defended in doctrinal and theoretical terms, (...) and by reference to both UK and US law. It is presented in three forms: first, in negative terms, that the orthodox distinction between the two claims (informational privacy and intrusion) is unsustainable; secondly, in positive terms, that both guard against the same wrong (unwarranted privacy-invasion) and the same harm (mental distress), in a way that is distinctive from other privacy actions and legal claims based upon the autonomy value; finally, in pragmatic terms, that MOPI’s mature jurisprudence is sufficiently flexible and dynamic to recognise intrusion-only claims using its existing legal framework.

Pietraszewski contends that group representations that rely on a “containment metaphor” fail to adequately capture phenomena of group dynamics such as shifts in allegiances. We argue, in contrast, that social categories allow for computationally efficient, richly structured, and flexible group representations that explain some of the most intriguing aspects of social group behaviour.

Research necessarily entails the close interrelation of concepts and arguments, including solutions to a range of meta-questions, whether acknowledged explicitly or not. Despite this, few detailed accounts currently exist that support researchers to develop their complex conceptual architectures, especially in critical realist spheres. Indeed, many published accounts often omit much of this ‘messiness’ that sits behind, yet is foundational to, research projects. Those accounts that do seek to portray how/why researchers have made decisions (e.g. about connections between research philosophy, (...) methodology, methods, theory and empirical evidence) tend to focus on one set of meta-questions, or occasionally on the relationships between two sets, at a time. Therefore, this paper presents a flexible framework – supported by specific examples from studies – that we hope will be useful in supporting researchers from all traditions, but especially critical realists, to carefully think through and develop more holistic connections in their conceptual architecture.

Despite sharing Catholic Social Teaching as their system of morals and both being confronted with marketisation pressures, working conditions at German and Belgian Catholic social service providers of elderly care differ. We argue that an interdisciplinary approach is needed to understand such differences, as interpretation of CST is mediated by local contexts. Working conditions result from interactions shaped by each country’s respective religious, legal and socio-economic contexts, providing players with different levels of discretion and power resources. In Belgium, working conditions (...) at Catholic elderly care providers tend to be better due to a strong Catholic trade union, encompassing labour market regulation and a universal legal system applying to all care providers. Moreover, there is strong interaction between these Catholic care providers and other Catholic institutions. By contrast, German CSSPs, operating as faith-based organisations with their own legal framework in a relatively liberalised and decentralised labour market, are able to use various flexibility practices which put pressure on working conditions. Using such practices is partially justified by the Catholic discourse on charity and altruism, stressing the particular nature of work in the Catholic care sector. Overall, the article demonstrates differences in the local application of CST. It also shows how transnational differences in working conditions at Catholic social service providers are the product of more than just local differences in the interpretation and application of CST principles, being shaped by interactions between a country’s specific religious, legal and socio-economic contexts.

Explores contemporary controversies in bioethics from a Hindu perspective. S. Cromwell Crawford breaks new ground in this provocative study of Hindu bioethics in a Western setting. He provides a new moral and philosophical perspective on fascinating and controversial bioethical issues that are routinely in the news: cloning, genetic engineering, the human genome project, reproductive technologies, the end of life, and many more. This Hindu perspective is particularly noteworthy because of India's own indigenous medical system, which is stronger than ever and (...) drawing continued interest from the West. The Hindu bioethics presented in this book are philosophically pluralistic and ethically contextual, giving them that conceptual flexibility which is often missing in Western religions, but which is demanded by the twenty-first century's complex moral problems. Comprehensive in scope and passionate in nature, Crawford's study is an important resource for analyses of practical ethics, bioethics, and health care. (shrink)

LANGUAGE NOTE | Document text in Chinese; abstract also in English. In this paper, I first reiterate the views of Lyreskog et al. and stress the importance of discussing ethical questions in the context of ABT—a topic that has clearly not received enough attention in China. Second, given the current state of Chinese applied ethics, I focus on what Lyreskog et al. refer to as a “seismic shift in how we conceptualize much of what we take to be core values (...) in medicine and healthcare” (Lyreskog et. al 2023, 11–34) to explain how to realize the innovative progress of ABT ethics in contemporary China. I agree in principle that frameworks aiming to offer ethical guidance in ABT situations should use ontologies and taxonomies that allow for conceptual flexibility and redesign. These frameworks should also be subjected to philosophical critique and modified in light of scientific practice. (shrink)

According to one productive and influential approach to cognition, categorization, object recognition, and higher level cognitive processes operate on a set of fixed features, which are the output of lower level perceptual processes. In many situations, however, it is the higher level cognitive process being executed that influences the lower level features that are created. Rather than viewing the repertoire of features as being fixed by low-level processes, we present a theory in which people create features to subserve the representation (...) and categorization of objects. Two types of category learning should be distinguished. Fixed space category learning occurs when new categorizations are representable with the available feature set. Flexible space category learning occurs when new categorizations cannot be represented with the features available. Whether fixed or flexible, learning depends on the featural contrasts and similarities between the new category to be represented and the individual's existing concepts. Fixed feature approaches face one of two problems with tasks that call for new features: If the fixed features are fairly high level and directly useful for categorization, then they will not be flexible enough to represent all objects that might be relevant for a new task. If the fixed features are small, subsymbolic fragments (such as pixels), then regularities at the level of the functional features required to accomplish categorizations will not be captured by these primitives. We present evidence of flexible perceptual changes arising from category learning and theoretical arguments for the importance of this flexibility. We describe conditions that promote feature creation and argue against interpreting them in terms of fixed features. Finally, we discuss the implications of functional features for object categorization, conceptual development, chunking, constructive induction, and formal models of dimensionality reduction. Key Words: concept learning; conceptual development; features; perceptual learning; stimulus encoding. (shrink)

How flexible is language? To what extent does language 'absorb' individual differences, for example physical interaction, in knowledge acquisition within a domain? Current neuropsychological findings show that conceptual knowledge is embodied. When reading the word 'cinnamon', supportive neural activity includes brain areas usually engaged in perceptual tasks. Such findings suggest that perceptual and somatosensory processes influence the conceptual knowledge of the competent language user. Here, I explore what I name the 'plasticity' of language, to hone in on characteristics (...) of language, which, once language is in place, might lessen the necessity of physical interaction with the environment during knowledge acquisition. Linguistic knowledge is acquired by way of structures that contain representations of previous physical interactions. This could explain how a person's experiences transcend the boundary of the individual and meaningfully translate into linguistic knowledge accessible to others, as seems to be the case in so-called interactional expertise; expertise acquired without physical interaction.

Despite the limitations of the classical typology, exclusivism, inclusivism, and pluralism continue to inspire interest as productive positions for a theology of religions. At the same time, initiatives of the type exemplified by Francis Clooney’s comparative theology suggest that a theology of religions has reached, if not a point of exhaustion, at least the need for a hiatus in which other approaches focused on inter-religious learning can chart alternative ways forward. The genius of David Cheetham’s Ways of Meeting and the (...) Theology of Religions is his capacity simultaneously to advance reflection on the classical typology of the theology of religions and direct attention to the territory of inter-religious encounter for which the typology may not account.The book is structured in four parts. In the first part, Cheetham reflects on the place for ‘conceptual flexibility,’ even playful imagination, in wrestling with religious difference and nicely exposes an affinity between tradition ..

Empirical evidence from developmental psychology and anthropology points out that the human mind is predisposed to conceptualize the world in particular, species-specific ways. These cognitive predispositions lead to universal human commonsense views, often referred to as folk theories. Nevertheless, humans can transgress these views – i.e. they can contradict them with alternative descriptions, they perceive as more accurate – as exemplified in modern sciences. In this paper, I enquire about the cognitive faculties underlying such transgressions. I claim that there are (...) three faculties enabling us to part with these universal commonsense views of the world imposed by our nature. The first is our ability to represent representations – i.e. to form metarepresentations. The second is our ability to produce alternative representations both by explaining a familiar subject matter in terms of the principles governing different conceptual domains than the one that we are predisposed to apply to the subject matter and by directing our mind to new subject matters (for which we have no predisposed conceptual grasp), understanding them in terms of familiar domains. The third, finally, is our ability to give these representations an epistemic orientation. Key words: Human cognition, Domain-specific knowledge systems, Cognitive predispositions, Folk theories, Cognitive flexibility, Human – nonhuman distinction. (shrink)

As consumers represent a key actor for the success of businesses implementing socially responsible strategies, companies need to gain further insights on the determinants of responsible behaviors. In this study, we provide a contribution to the ongoing debate on responsible consumers by means of an integrative literature review, which analyzes a set of competing models mainly from social psychology and marketing. Stemming from this preliminary analysis of the existing evidence, we develop a new conceptual model, that is, a framework (...) based on (i) a flexible setting of the boundaries of analysis, (ii) a broader lens taking into account interrelations across behaviors, and (iii) a dynamic approach. The framework, for which an exemplary use is illustrated, represents the basis for advancing a rich agenda for future research. The latter is aimed at overcoming current criticalities in responsible consumer research, and it develops around the need for an integrative, dynamic, and cross-cultural approach on the one hand, and the elaboration of new perspectives on single antecedents, on the other.

To approach the many challenges involved in the notion of engineering concepts, it is important to have a clear idea of the starting point – the concepts that people use in their everyday lives, in conversations and in expressing beliefs, desires, intentions and so forth. The first Section of this chapter introduces evidence that I have accumulated over the last many years concerning the flexibility, context-dependence, and vagueness of such common concepts. The concept engineer needs to understand the structure (...) of the “raw material” with which she is working. In Section 2, I summarise some results concerning the amount of individual variation that exists within a single relatively homogenous population of individuals, both in what examples are considered most typical of a category, and in what properties are considered most central to a category (Hampton & Passanisi, 2016). The demonstration of a significant degree of reliable variation in responses to these questions, that is stable over time, illustrates the potential for conceptual engineering interventions to affect individuals’ concepts. Concepts are rarely fixed or uniformly understood in the same way. I then discuss the different ways in which concepts track the world, and I speculate about how different conceptual domains are governed by different criteria of validity or acceptability. This reflection will lead to Section 3 in which I summarise some results from recent research (Thorne, Quilty-Dunn, Smortchova, Shea, & Hampton, 2021), investigating for the first time how people view the value of different familiar concepts. Knowing how people appraise concepts will be a key to developing ideas for improving the reliability and validity of the concepts that they commonly use. A final section contains some (largely speculative) discussion about the implications of work in psychology of concepts for the project of conceptual engineering. (shrink)
