In this paper we reflect on the effectiveness of cognitive mapping as a method to study farm functioning in its complexity and its diverse forms in the framework of our own experiment with a diverse group of Flemish beef farmers. With a structured direct elicitation method we gathered 30 CMs. We analyzed the content of these maps both qualitatively and quantitatively. The central role of the concept “Income” in most maps indicated a shared concern for economic security. Further, the (...) CMs indicated that farmers dealt with this shared social reality differently, as the relationships included in their maps referred to different functional processes relating to revenue streams, marketing strategies, investment decisions, dependence on production inputs, on-farm resource management, and personal well-being. With a clustering algorithm we grouped farmers based on the relationships in their maps, which allowed us to trace some of the broader patterns within the data, such as the existence of more business- and investment-minded farmers, in contrast to farmers focused on their quality of life, and animal production-oriented in contrast to marketing-oriented farmers. Taking into account farmers’ comments, we find that the applied methods had limited capability to classify farmers based on their perspectives on farming. Still, the system presentations proved useful to study what aspects farmers were working on or towards, and how these aspects may actually fit together as a whole. CMing was therefore mostly effective in exploring farm functioning in its complexity, and less so in exploring farm functioning in its diversity. (shrink)

In some recent papers, the authors and Peter Gärdenfors have defined and studied two different kinds of formal operation, conceived as possible representations of the intuitive process of contracting a theory to eliminate a proposition. These are partial meet contraction (including as limiting cases full meet contraction and maxichoice contraction) and safe contraction. It is known, via the representation theorem for the former, that every safe contraction operation over a theory is a partial meet contraction over that theory. The purpose (...) of the present paper is to study the relationship more finely, by seeking an explicit map between the component orderings involved in each of the two kinds of contraction. It is shown that at least in the finite case a suitable map exists, with the consequence that the relational, transitively relational, and antisymmetrically relational partial meet contraction functions form identifiable subclasses of the safe contraction functions, over any theory finite modulo logical equivalence. In the process of constructing the map, as the composition of four simple transformations, mediating notions of bottom and top contraction are introduced. The study of the infinite case remains open.

Lindquist et al. have assumed that functional specialization requires a one-to-one mapping between brain regions and discrete emotions. This assumption is in tension with the fact that regions can have multiple functions in the context of different, possibly distributed, networks. Once we open the door to other forms of functional specialization, neuroimaging data no longer favor constructionist models over natural kind models.

Health research initiatives worldwide are growing in scope and complexity, particularly as they move into the developing world. Expanding health research activity in low- and middle-income countries has resulted in a commensurate rise in the need for sound ethical review structures and functions in the form of Research Ethics Committees (RECs). Yet these seem to be lagging behind as a result of the enormous challenges facing these countries, including poor resource availability and lack of capacity. There is thus an (...) urgent need for ongoing capacity and resource development in these regions in general, and in Africa in particular. Similarly, there is a need for research and initiatives that can identify existing capacity and funding and indicate the areas where this needs to be developed.This discussion paper argues that the Mapping African Research Ethics Capacity (MARC) project is a timely initiative aimed at identifying existing capacity. MARC provides a platform and tool on the Council on Health Research for Development's (COHRED) Health Research website (HRWeb), which can be used by RECs and key stakeholders in health research in Africa to identify capacity, constraints and development needs. MARC intends to provide the first comprehensive interactive database of RECs in Africa, which will allow for the identification of key relationships and analyses of capacity. The potential of MARC lies in the mapping of current ethical review activity onto capacity needs. This paper serves as a starting point by providing a descriptive illustration of the current state of RECs in Africa. (shrink)

Maria Kronfeldner’s Preface and Introduction to the Routledge Handbook of Dehumanization maps the landscape of dehumanization studies. She starts with a brief portrayal of the history of the field. The systematically minded sections that follow guide the reader through the resulting rugged landscape represented in the Handbook’s contributions. Different realizations, levels, forms, and ontological contrasts of dehumanization are distinguished, followed by remarks on the variety of targets of dehumanization. A discussion on valence and emotional aspects is added. Causes, functions, and (...) consequences of dehumanization, and the prospects for reducing or undoing it, are introduced. The systematic overview closes with a discussion of some important theoretical complexities that arise in studying dehumanization. After these systematic sections, the scholarly work on dehumanization gets situated in the broader intellectual landscape of debates about the ‘human’ in the humanities and social sciences. The Introduction ends with some notes on scope, limitations, and intended readership of the Handbook. (shrink)

Philosophical counselling in South Africa has developed over several decades alongside, and often closely aligning with, broader movements originating in Europe. As elsewhere, the practice has taken root in a heterogeneous range of forms. While early scholarly engagements offered important theoretical mappings of philosophical counselling, comparatively little systematic attention has been given to how the practice has adapted in South African contexts. In this article, I provide a nomadic cartography, that is, a non-exhaustive, movement-sensitive mapping, focusing on public self-descriptions (...) of practising South African philosophical counsellors. I offer an interpretation of how their practices appear through publicly available self-authorised descriptions of method and aim. Websites are understood here as significant, as for many prospective counselees such profiles constitute the practical horizon of what philosophical counselling is. This cartographic exercise subsequently maps overlapping tendencies along three orientating dimensions: the telos/orientation of practice (ranging from ameliorative aims to wonder); the dominant method (rational-logical to relational- hermeneutic); and the locus from which philosophical counselling is articulated (universalist to situated). Through this mapping, a diverse yet uneven landscape of practices is revealed that might appear as a field in disarray, but is better understood as a necessary plurality within a functioning ecology. While several established orientations are identifiable, a relative absence emerges through the mapping process of approaches that are simultaneously deeply situated and hermeneutic. In response, I conclude by locating this unoccupied position, suggesting that its recognition is a contribution to a fuller and more pluralistic ecology of philosophical counselling in South Africa.

There has been considerable debate in the literature as to whether work in experimental philosophy actually makes any significant contribution to philosophy. One stated view is that many X-Phi projects, notwithstanding their focus on topics relevant to philosophy, contribute little to philosophical thought. Instead, it has been claimed the contribution they make appears to be to cognitive science. In contrast to this view, here we argue that at least one approach to X-Phi makes a contribution which parallels, and also extends, (...) historically salient forms of philosophical analysis, especially contributions from Immanuel Kant, William James, Peter F. Strawson and Thomas Nagel. The framework elaborated here synthesizes philosophical theory with empirical evidence from psychology and neuroscience and applies it to three perennial philosophical problems. According to this account, the origin of these three problems can be illuminated by viewing them as arising from a tension between two distinct types of cognition, each of which is associated with anatomically independent and functionally inhibitory neural networks. If the parallel we draw, between an empirical project and historically highly influential examples of philosophical analysis, is viewed as convincing, it follows that work in the cognitive sciences can contribute directly to philosophy. Further, this conclusion holds whether the empirical details of the account are correct or not. (shrink)

Exponential mappings into an imaginary space or number field for the axioms of a theory, which are in the form of propositional constants and variables, make possible: (a) an understanding of the meaning and differences between the Lorentz transformation constants, such that their product is still equal to one, but the axioms at each end of the transformations are logically inverse and separately consistent; (b) an interpretation of the psi function phase factor which is part of the axiomE=hf; (...) (c) the unification of the quantum-mechanical psi function and the electromagnetic wave function. Thus, those statements whose mechanisms are unknown (the axioms of the theory) are to be assigned the axiom propositional number symbol ϑ and are to be associated with the complex probability eiϑ, which is a uniform factor of the energy equations expressing the physical state. Such probabilistic axiom functions can be associated with both the special theory of relativity and the quantum-electromagnetic theory. (shrink)

Predictive processing is an ambitious neurocomputational framework, offering an unified explanation of all cognitive processes in terms of a single computational operation, namely prediction error minimization. Whilst this ambitious unificatory claim has been thoroughly analyzed, less attention has been paid to what predictive processing entails for structure–function mappings in cognitive neuroscience. We argue that, taken at face value, predictive processing entails an all-to-one structure–function mapping, wherein each individual neural structure is assigned the same function, namely minimizing (...) prediction error. Such a structure–function mapping, we show, is highly problematic. For, barring few, rare occasions, such a structure–function mapping fails to play the predictive, explanatory and heuristic roles structure–function mappings are expected to play in cognitive neuroscience. Worse still, it offers a picture of the brain that we know is wrong. For, it depicts the brain as an equipotential organ; an organ wherein structural differences do not correspond to any appreciable functional difference, and wherein each component can substitute for any other component without causing any loss or degradation of functionality. Somewhat ironically, the very neuroscientific roots of predictive processing motivate a form of skepticism concerning the framework’s most ambitious unificatory claims. Do these problems force us to abandon predictive processing? Not necessarily. For, once the assumption that all cognition can be accounted for exclusively in terms of prediction error minimization is relaxed, the problems we diagnosed lose their bite. (shrink)

Mature representations of number are built on a core system of numerical representation that connects to spatial representations in the form of a ‘mental number line’. The core number system is functional in early infancy, but little is known about the origins of the mapping of numbers onto space. Here we show that preverbal infants transfer the discrimination of an ordered series of numerosities to the discrimination of an ordered series of line lengths. Moreover, infants construct relationships between (...) individual numbers and line lengths that vary positively, but not between numbers and lengths that vary inversely. These findings provide evidence for an early developing predisposition to relate representations of numerical magnitude and spatial length. A central foundation of mathematics, science and technology therefore emerges prior to experience with language, symbol systems, or measurement devices. (shrink)

This chapter examines a system that is capable of a rather more sophisticated form of spatial representation, particularly a system that enables an organism to find its way about by forming a topographic map of the surrounding environment. It discusses a topographic mapping system and suggests that it is able to identify particular places in a way that is quite distinct from the capacity to keep perceptual track of them. The chapter also evaluates a claim that an organism (...) that possesses a topographic mapping system must be able to represent itself. (shrink)

Ethics advisory groups, in various forms, have existed for at least 50 years in the United States and other countries. In science and biomedicine, four principal types of committees can be distinguished: policy-making and/or advisory committees, health professional association committees, health care ethics committees, and research ethics committees. Overall, these bodies have been of use to governments, policy makers, health care professionals, and the public in considering ‘what is ethical’ and ‘what is unethical’ in areas such as research involving humans (...) or animals or environmental questions such as whether to use genetically modified crops.

The article regards children’s literature as a certain cultural tool. This approach enables to reveal various characteristic aspects of the poetics of children’sliterature, while relating them to children’s cognitive and cultural development. Focusing on a book series Paula’s Life by Estonian author Aino Pervik, it can beseen how two different ways of understanding — the initial, so-called mythological type of thinking of preschoolers and the emerging conceptual thinking — arecombined.The article draws mostly on the concepts of cultural psychology and the (...) authors of Tartu–Moscow school of semiotics, who have elaborated the idea thatproper names form one of the central components of mythological consciousness, the latter being comparable to “the language of proper names”. The main attention is drawn on the functioning of names and the topic of naming and categorizing in these texts. (shrink)

This chapter considers the dynamic nature of the relationship between place, memory and identity, with reference to a map of Terténia drawn by A.M. This is pursued in three ways. First, via a discussion which argues that topography and biography, memories and maps are closely connected. Second, through an analysis of the map with reference to the formal categories defined by Gunnar Olsson and Kevin Lynch. It follows that the map is characterized by a “comprehensible appearance” and points to intrinsic (...) meanings. Comprehensible appearance implies an implicit connection between place of origin and identity; intrinsic meanings refer to the function of the map, whose overall meaning is geographically imagined as post-journey. The map will thus related to the category of hodologic space, as defined by Pietro Janni and inspired by the work of memory of the specific category of geographers whose work was aimed at providing full sense and coherence to the places they explored. Third, in a survey of the toponimy in the map, between memory and experience. What appears on this map of routes is the very personal signs of the explorer that inscribes itself in place of the existing toponymy of Terténia, and presupposes some form of appropriation of the place itself. The chapter passes over the established ideas of place and identity to arrive at the idea that place and identity are from time to time processes constructed and imagined in a complex and dynamic game of topicality, position and forgetting.

A comprehensive excursion, into anthropology, ethnography, linguistics, social and political science lead me to the conclusion that human societies are ruled by systems of shared concepts, and that these systems of thought function as a kind of public or external mind, which produces and maintain the social forms of life. Taking into account the fact that philosophy originally - in ancient Greece - was a ‘public affair’, I came up with the idea that philosophy should try to map the (...) public mind. In other words, the idea that philosophers should draw up a project for making what I call philosophical maps, i.e. maps of public thought. In what follows, I will give a brief account of this idea in the hope that other philosophers may draw inspiration from it. Of course, all this involves speculation, but it does not interfere with regular philosophy. It simply adds something to it from the outside as it were, that is from a descriptive point of view. As I will make clear, this idea is consistent with the efforts of Wittgenstein to achieve a radical descriptive philosophy. (shrink)

Garrison Blueprints and maps are propositions and they exemplify what it is to be propositional.1 [E]very characteristic trait is a quality.... produced and destroyed by existential conditions.2 John Dewey's claim that there are metaphysical generic traits of existence the theory of which provides "a ground-map" for cultural criticism remains controversial. I will work along two intertwining lines to try and (...) clear things up a bit. First, many assume that his reference to a metaphysical map is a metaphor. My paper will show that he uses the idea of a map consistently in many different places throughout his career. Second, my paper will examine how Dewey functionally coordinates ordinary existential traits and their maps within his theory of judgment. We will find that the generic traits and the ground-map of criticism connect in much the same way. Before examining Dewey's theory of judgment, I want to say something about where Dewey's metaphysics fits into his empirical "denotative method." In the conclusion, we wiU look at where metaphysics fits into the architectonic of his entire phUosophy. In between, we wiU examine maps functioning as propositions (especiaUy logical and mathematical universals) as weU as ever-evolving guides to unending inquiry in an unfinished and unfinishable universe. Eventually we wiU see why Dewey insists that "the social" is "The Inclusive PhUosophic Idea." Metaphysics, for Dewey, is simply one tool of cultural criticism among others.

PEIRCE SOCIETY Vol. 41, No. 4 ©2005 O situation from whence we may select traits, through the experience of "significant " linguistic meanings, such as the propositions of judgment, to the experience of "knowing" as the product of the logical process of inquiry, and back again to primary experience.4 Each phase interpenetrates every 3 other. Here is how Dewey describes the trans-action between primary, noncognitive and secondary, cognitive experience in his original (1925) >■$ introduction to Experience and Nature: ^r There are two avenues of approach to the goal of philosophy. We may " begin with experience in gross, experience in its primary and crude forms ^ [e.g., traits].... Or, we may begin with refined selective products, the a most authentic statements of commended methods of science [e.g., ¿q maps], and work from them back to the primary facts of life. ^ P TT ϕ > Philosophy may start with either immediate existential experience or the 3 experience of mediating meanings. While we may distinguish these two L starting points, we should never construct a dualism from them since both jx occur within experience.6 Dewey explains that "the subject-matter of primary experience sets the problems and furnishes the first data of reflection ""O which constructs the secondary objects of reflection."7 Further, "crude or macroscopic experience" provides the "test and verification" of the secondary objects of reflection. Secondary objects "explain the primary objects, 2 they enable us to grasp them with understanding!'9 The two starting points " differ in direction, but eventually they close to form a circle of expanding? dence. They may then pioneer new pathways, or, having different values, D choose to construct different kinds of maps. ^ Douglas Browning distinguishes "three phases of discussion of the start- 0 ing point."23 The first concerns "the designation of a certain subject matter P1 referred to under the names 'experience' and 'my life'."24 Dewey's empirical « denotative method selects aspects from immediate qualitative experience.

In lieu of an abstract, here is a brief excerpt of the content:Drama on the Run:A Prelude to Mapping the Practice of Process DramaPamela Bowell (bio) and Brian Heap (bio)In the current educational climate prevailing in a number of countries, increased emphasis is being placed on the concept of "the artist in schools." Funding is being channeled to support a range of initiatives and schemes that are designed to bring arts professionals from all the art forms into the classroom (...) where they place their artistic talents, knowledge, and insights alongside the pedagogic skills of the teacher.We see exciting projects in which artists work with children in school—visual artists to create murals, musicians to compose and perform operas, dancers to choreograph new ballets, and actors and directors to devise plays. Many of the outcomes are of high quality, and the children who have been fortunate enough to be involved have enjoyed the experiences and have gained a great deal from them. This would seem to be a state of affairs to be applauded unreservedly, as such projects surely enrich the lives of the pupils and schools in which they take place. In one sense, of course, this is undeniably true, and we have no intention of suggesting otherwise. However, in reality, this is a much more complex situation. It raises a number of key issues for us as educational practitioners who work in the field of applied theatre, sharing with others, as Judith Ackroyd describes, "a belief in the power of the theatre form to address something beyond the form itself."1The most critical issue is the perceived separation of the artist from the teacher that can sometimes be encouraged by artists in schools projects. We sense a dangerous precedent here. It becomes all too easy for two erroneous assumptions to be made, namely that teachers cannot be considered to be artists in their own right, while artists on the other hand can be accorded [End Page 58] the status of teacher. In our own experience too, the nature of educational funding can be extremely volatile, subject to all kinds of shifts in the prevailing political and economic climate, as well as adjustments to the ways in which funding is applied according to the social and educational priorities of the time. Too frequently, education falls victim to what might be described as "the-flavor-of-the-month syndrome."Those who are involved with teacher education, both pre- and in-service, make superhuman efforts to respond with alacrity to the new demands as courses are reviewed and reorganized accordingly. The trainees of the next generation find themselves with a new "party line" to toe as their courses conform to the new priority. This is all well and good—until the priority changes and gaps suddenly appear in the knowledge or skills or understanding of teachers. What was received wisdom becomes a deficit model as focus changes, and the circle is now expected to be squared.Under these circumstances, it would seem a more prudent policy to train teacher-artists who would have the ability to meld their pedagogical understanding and skill with an aesthetic craft and sensibility than to rely on visiting artists as the "natural" or "normal" providers of arts education. This would ensure not only that teachers would make better, more informed use of visiting artists but also that children's expertly guided engagement with the arts would be a permanent and enduring aspect of their regular schooling rather than a "special" event subject to the vagaries of arts funding or policy. This might seem an easy statement to make for people such as ourselves, who have spent whole careers working as teacher-artists within the field of drama in education. But it might seem an altogether more daunting prospect for teachers, or intending teachers, who are not specialists in the arts.Having spent a great deal of our respective careers working in teacher education, we are very conscious of this possibility. To this end, our research collaboration has been centered on exploring and coming to understand more fully, clearly, and precisely how the teacher functions as an artist within the particular genre of applied theatre known as process drama. Embedded within the increase of our... (shrink)

The author has collaborated in research teams to visualize supercomputer simulations and real-time data. She describes these collaborative projects that employ advanced-technology graphics and novel digital displays that include large-format IMAX film, high-definition television productions, and a museum digital dome at the American Museum of Natural History. The popularity of these images and the function that they provide in popular culture are discussed. She also describes two key technologies that she was part of designing: IntelliBadge(tm), a real-time visualization and (...) ‘smart’ tracking system; and Virtual Director(tm), a virtual camera choreography and remote collaboration system. The process of data-visualization involves the mapping of data from numerical form into an iconic representational form in the attempt to provide humans with insight and understanding of a phenomenon. This is discussed in the context of metaphor, cognition, and postcolonial theory. Because data-visualizations carry the ‘weight of scientific accuracy and advanced technology’, most general audiences confuse these visualizations as ‘real’; however, it is argued that data-visualizations are models and metaphors, not reality. In metaphor theory, the mapping of attributes from one domain of information into another is how humans understand, create, and engender new meaning. Data mapping is correlated with this theory. The author explores how the use of mapping information is culturally contingent. In the spirit of scientific inquiry, she deconstructs the very professional activity for which she is most famous.

Many physicians, anatomists and natural philosophers engaged in attempts to map the seat of the soul during the so-called Scientific Revolution of the European seventeenth century. The history of these efforts needs to be told in light of the puzzlement bred by today's strides in the neurological sciences. The accounts discussed here, most centrally by Nicolaus Steno, Claude Perrault and Thomas Willis, betray the acknowledgement that a gap remained between observable form, on the one hand, and motor and sensory (...) functions, on the other. Observation yielded information about form, but did not guarantee a constant correlation with presumed function, while the mechanisms of sense and movement did not fit in with accounts of action and cognition whose purpose was to place the connection between active body and willful, conscious soul onto a descriptive rather than metaphysical plane. Teleology was now no longer a helpful tool in the disciplines of anatomy and physiology; the consequences of this are still with us. (shrink)

Marketing communication in modern times is similar to the propaganda model, i.e. persuasive communication in all possible fields of exploitation. The last three decades in Central and Eastern Europe constituted a time of transformation in many areas of social, political and economic life. Thanks to immanent changes depending on the economic situation and the clash of demand and supply, it was possible to create functional models in three selected time intervals distinguished by the author (socialism, transformational period and capitalism). The (...) use of functional models gives the opportunity to indicate how many changes have taken place in such a short period of time both in terms of consumer mentality and in satisfying the needs of producers. The basis for the application of this type of operationalization of the idea is the statement that “the functional model consists in mapping the functioning of a given system. It should give an idea of the functions and processes taking place in a given system” (Sabryła, Trzciniecki 1986). The purpose of this article is also to start a discussion on contemporary models of product communication. (shrink)

While the past century of neuroscientific research has brought considerable progress in defining the boundaries of the human cerebral cortex, there are cases in which the demarcation of one area from another remains fuzzy. Despite the existence of clearly demarcated areas, examples of gradual transitions between areas are known since early cytoarchitectonic studies. Since multi-modal anatomical approaches and functional connectivity studies brought renewed attention to the topic, a better understanding of the theoretical and methodological implications of fuzzy boundaries in brain (...) science can be conceptually useful. This article provides a preliminary conceptual framework to understand this problem by applying philosophical theories of vagueness to three levels of neuroanatomical research. For the first two levels (cytoarchitectonics and fMRI studies), vagueness will be distinguished from other forms of uncertainty, such as imprecise measurement or ambiguous causal sources of activation. The article proceeds to discuss the implications of these levels for the anatomical study of connectivity between cortical areas. There, vagueness gets imported into connectivity studies since the network structure is dependent on the parcellation scheme and thresholds have to be used to delineate functional boundaries. Functional connectivity may introduce an additional form of vagueness, as it is an organizational principle of the brain. The article concludes by discussing what steps are appropriate to define areal boundaries more precisely. (shrink)

This paper aims to understand how and why tree diagrams are of central importance to microbiome scientists in their practices of meaning making. The interfaces that scientists use are, in fact, topological structures that organize the genetic data generated by sequencing technology. They establish relationships among microbes and also between microbes and the conditions of the ecological niche they help construct. The tree structure is a powerful _topos_ of knowledge organization in Western culture. However, biomolecular research has revealed the existence (...) of horizontal gene exchange among microbes and other merging forms; these cast doubt on the tree as a valid representational metaphor for the tangle of the microbial world and help to overcome neo-Darwinism. This essay analyzes the software and interfaces used by microbiome scientists as tools for organizing knowledge that shape how we see human-microbe relationships, while escaping a representational function. While trees have long been considered representative forms of visualization of an evolutionary paradigm, we emphasize the non-illustrative and heuristic power of these interfaces, which, although steeped in centuries of reflection and debate on evolutionary theories, respond more to a diagrammatic logic: tools for discovering the new from genetic “black matter” and for exploring new forms of relationships between microbes and humans.

This article explores the relationship between sexual science and evolutionary models of human development and progress. It examines the ways in which late 19th- and early 20th-century Western European sexual scientists constructed the sexual instinct as an evolutionary force that not only served a reproductive purpose, but was also pivotal to the social, moral, and cultural development of human societies. Sexual scientists challenged the idea that non-reproductive sexualities were necessarily perverse, pathological, or degenerative by linking sexual desire to the evolution (...) of sociality, often focusing on forms of relationality and care that exceeded biological kinship. As a result, non-reproductive sexual expressions, including homosexual and non-reproductive heterosexual behaviours, were interpreted as manifestations of a sexual instinct operating in the service of human development. These claims were reliant on cross-cultural and historical comparisons of sexual values, behaviours, and customs that rehearsed and reinforced imperial narratives of development premised on racialized, gendered, and classed hierarchies. Sexual scientists mapped diverse sexual behaviours in terms of their perceived evolutionary benefits, contributing to colonial narratives that distinguished between different cultures according to imagined trajectories of development. These contestations around the sexual instinct and its developmental functions played a vital role in allowing sexual science to authorize itself as a field of knowledge that promised to provide expertise required to manage sexual life and secure the global development of human civilization.

A key factor that affects whether and at what age children can demonstrate an understanding of false belief and complement‐clause constructions is the type of task used (whether it is implicit/indirect or explicit/direct). In the current study, we investigate, in an implicit/indirect way, whether children understand that a story character's belief can be true or false, and whether this understanding affects children's choice of linguistic structure to describe the character's belief or to explain the character's belief‐based action. We also measured (...) children's understanding of false belief in explicit false‐belief tasks. English‐ and German‐speaking young 4‐ and 5‐year‐olds as well as English‐ and German‐speaking adult controls heard complement‐clause constructions in a story context where the belief mentioned in the complement clause (e.g., “He thinks thatshe's not feeling well”) turned out to be false, true, or was left open. After hearing the test question (“Why does he not play with her?”), all age groups were most likely to repeat the whole complement‐clause construction when the belief turned out to be false. That is, they tended to explicitly refer to the character's perspective and say “He thinks…” When the belief turned out to be true, participants often reverted to a simple clause (“She's not feeling well”). Furthermore, children with better short‐term memory were more likely to repeat the whole complement‐clause construction. However, children's performance in explicit false‐belief tasks showed no relation to their performance in our novel, more implicit/indirect, task. Whether or not the complement clause was introduced by athatcomplementizer only had a small effect on the German adults’ responses, where leaving out the complementizer also changes the word order of the complement clause. Overall, our results suggest that task characteristics and individual differences in short‐term memory affect children's ability to demonstrate false‐belief understanding and to express this understanding linguistically.

Palm-up (PU) is among the most frequent manual forms across signed languages, yet its functional range and form-function mapping remain poorly understood. This study presents a corpus-based analysis of PU in Chinese Sign Language (CSL), drawing on 793 tokens from 15.6 h of naturalistic interaction across three generations of signers. All tokens were coded for function, handshape, movement, clausal position, and non-manual features. PU in CSL is restricted to three functional domains: negation (61 %), discourse marking (...) (28 %), and interrogation (11 %), which together account for 100 % of the corpus with no propositional functions attested. Each domain is associated with a stable bundle of formal features, forming a gradient from context-dependent discourse uses to morphologically bound affixal forms. Age-based analysis shows that the functional inventory is stable across cohorts while internal weighting has shifted, reflecting differential entrenchment consistent with ongoing grammaticalization. These findings support the view that PU is specialized for intersubjective meaning, managing cognitive coordination between signer and addressee, and that this specialization reflects both the iconic, addressee-directed properties of the open-palm form and the conventionalization history of individual signing communities.

Cognitive Grammar postulates two modes of cognitive processing for the structuring of complex scenes, summary scanning and sequential scanning. Generally speaking, the theory is committed to basing grammatical concepts upon more general cognitive principles. In the case of summary and sequential scanning, independent evidence is lacking, but Langacker argues that the distinction should nonetheless be accepted as it buys us considerable theory-internal explanatory power. For example, dynamic prepositions, to-infinitives and participles (e.g., into, to enter, entered ) are distinguished from finite (...) and bare verbs in terms of summary vs. sequential scanning. In this paper, we try to show that various theory-internal and theory-external arguments do not seem to support the two scanning modes. In particular, we offer a detailed examination of causatives (e.g., get, make ) and argue that their complementation patterns are difficult to reconcile with differences in scanning. We conclude that the status of, and need for, summary and sequential scanning in (Cognitive) grammar is doubtful, especially if grammar is approached from the viewpoint of the language learner/user. It follows also that the parcelling of some form-function mappings may prove less clear-cut than previously assumed. (shrink)

This study adopted a mixed-method study design to investigate the acquisitional features of English existential constructions at the syntax-pragmatics interface by Chinese learners, and explore the factors for non-native performance from the perspective of the Interface Hypothesis. A questionnaire was administered online to 300 Chinese learners of English and 20 English natives at a university in China, which included a picture description test and a context-matching test. Follow-up interviews were conducted with 30 Chinese learners. The experimental data were conducted using (...) comparing means and generalized linear mixed model. Results showed that Chinese learners overproduced existential constructions and reached a native-like level until the advanced stage. Moreover, Chinese learners displayed different preference patterns for existential constructions from English natives, and basically reached a native-like level by the intermediate stage. The qualitative data provided possible explanations for non-native performance. The analysis revealed that non-native performance in production attributed to L1 negative transfer and input frequency, while that in comprehension resulted from underspecification of form-function mapping, input frequency and contexts. Based on the findings, some implications on syntax-pragmatics teaching and L2 interface studies are provided. (shrink)

Indirect speech is a remarkable trait of human communication. The present paper tackles the sociobiological underpinnings of communicative indirectness discussing both socio-interactional and cognitive rationales behind its manifestation in discourse. From a social perspective, the use of indirect forms in interactions can be regarded as an adaptive response to the epistemic implications of transacted new information in small primary groups, representing – in Givón’s terms – our “bio-cultural” descent. The design features of indirect strategies today may therefore be explained in (...) terms of a form-function mapping in which indirect communicative expressions allowed a “safer” transaction of contents and a more cooperative attitude of speakers in both face-to-face and public contexts of communication. The unchallengeability effects notably induced by underencoded meanings have now received extensive experimental backing, unveiling intriguing underlying cognitive mechanisms such as the well-known cognitive illusions or fallacies.

The introduction and tracking of individuals over extended discourse, known as referential movement, is a central feature of coherence, and accounts for 'about every third word of discourse'. Located at the intersection of pragmatics and grammar, reference is now proving a rich and enduring source of insight into second language development. The challenge for L2 learners involves navigating the selection and positioning of reference in the target language, continually shifting and balancing the language used to maintain coherence, while remaining acutely (...) sensitive to the discourse and social context. The present volume focuses on how L2 learners meet that challenge, bringing together both eminent and up-and-coming researchers in the field of L2 acquisition. The chapters address a range of problems in SLA (e.g. form-function mapping, L1 influence, developmental trajectories), and do so in relation to various theoretical approaches to reference (e.g. Accessibility Theory, Givenness Hierarchy). The global outlook of these studies relate to the L2 acquisition of English, French, Japanese, Korean, and Spanish and cover a diverse range of situational contexts including heritage language learning, English as a Medium of Instruction, and the development of sociolinguistic competence.

The meaning of a formula built out of proof-functional connectives depends in an essential way upon the intensional aspect of the proofs of the component subformulas. We study three such connectives, strong equivalence (where the two directions of the equivalence are established by mutually inverse maps), strong conjunction (where the two components of the conjunction are established by the same proof) and relevant implication (where the implication is established by an identity map). For each of these connectives we give a (...) type assignment system, a realizability semantics, and a completeness theorem. This form of completeness implies the semantic completeness of the type assignment system. (shrink)

Arbitrariness is a distinctive feature of human language, and a growing body of comparative work is investigating its presence in animal communication. But what is arbitrariness, exactly? We propose to distinguish four notions of semiotic arbitrariness: a notion of opaque association between sign forms and semiotic functions, one of sign‐function mapping optionality, one of acquisition‐dependent sign‐function coupling, and one of lack of motivatedness. We characterize these notions, illustrate the benefits of keeping them apart, and describe two reactions (...) to our proposal: abandoning arbitrariness‐talk in favor of the newly introduced conceptual vocabulary, or feeding the distinctions back into the parent concept.

Dissociation thought experiments like Zombie and Inverted Spectrum cases play an essential role in the qualia debate. Critics have long since argued that these cases raise serious epistemic issues, undermining first person access to phenomenal states also in normal subjects. Proponents have denied this because, due to their phenomenal experience, normal subjects have epistemic abilities that Zombies don’t have. Here I will present a modified version of these thought experiments: Part-time Zombies and Part-time Inverts switch between normal and abnormal states (...) every now and then. Thus they provide insight into their epistemic situation showing that the mere possibility of Zombies and Inverts has consequences which undermine essential epistemic features of phenomenal properties even in normals. This line of reasoning will be corroborated by theoretical considerations on the epistemic requirements of phenomenal states. All this provides support for the “functional mapping hypothesis.” According to this hypothesis, any significant phenomenal difference can be mapped to a specific functional difference which is accessible from the third person perspective as well.

Formulas of n variables of Łukasiewicz sentential calculus can be represented, via McNaughton’s theorem, by piecewise linear functions, with integer coefficients, from hypercube [0,1] n to [0,1], called McNaughton functions. As a consequence of the McNaughton representation of a formula it is obtained a canonical form of a formula. Indeed, up to logical equivalence, any formula can be written as an infimum of finite suprema of formulas associated to McNaughton functions which are truncated functions to $[0,1]$ of the restriction (...) to [0,1] n of single hyperplanes, for short, called simple McNaughton functions. In the present paper we will concern with the problem of presenting formulas of Lukasiewicz sentential calculus in normal form. Here we list the main results we obtained: a) we give an axiomatic description of some classes of formulas having the property to be canonically mapped one-to-one onto the class of simple Mc Naughton functions; b) we provide normal forms for Lukasiewicz sentential calculus, making use of formulas defined in a); c) we prove the polynomial complexity of formulas, in normal form, coming from a certain class described as in a); d) we extend the results described in a), b) and c) to Rational Lukasiewicz logic.

In lieu of an abstract, here is a brief excerpt of the content:The Meanings and Function of Anti-System Ideology in the Weimar RepublicBen LiebermanThere are few, if any, ideological terms in the extensive historiography of the Weimar Republic so omnipresent and yet at the same time so obscure as the word “system.” Historical accounts of the Weimar Republic are strewn with references to the “system.” In recent works on the Weimar Republic Hagen Schulze points to the opposition of bourgeois (...) (bürgerliche) parties to the “Weimar ‘system,’ “ Detlev Peukert notes “hatred of ‘the system,’ the political and social order of the Republic”; Knut Borchardt observes the loss of faith in the capacity of “the system” to satisfy expectations; and Hans Mommsen refers to the “political system,” the “party system” and the “parliamentary system.” 1Historians, whatever their other differences, agree that mounting opposition to the System weakened the Weimar Republic, but the usefulness of this observation requires analysis of the meaning or meanings of the System. What, then, was the Weimar System? Surprisingly, many accounts of the Weimar Republic do not even attempt to provide a definition of the System, and the term receives only cursory treatment in several specialized works on ideology of the Weimar era. 2 Anti-System politics does receive attention, but Thomas [End Page 355] Childers’s insightful and pioneering essay on “anti-system politics” concentrates on mobilization against the System rather than on the problem of defining it. 3The best existing analysis of the System in Kurt Sontheimer’s valuable study of anti-democratic thought in the Weimar Republic suggests that historians cannot take the meaning of the term as a given. Sontheimer establishes that the System formed part of the array of anti-democratic thought of the Weimar Republic, but he also notes that the term’s meaning cannot easily be pinned down. The System conveyed a variety of political and economic meanings and ultimately formed a “nationalist counter myth.” 4During the Weimar Republic, attacks against the System emanated from a wide range of sources, most notably from a variety of nationalists as well as from Communists. Nationalists of many leanings detested the System. The DNVP (German National People’s Party), the largest political party of the right for most of the Weimar Republic, hated the System. So, too, did conservative revolutionaries and völkisch (ethnic or racist nationalist) groups including nationalist associations and the National Socialists. At the other end of the political spectrum, attacks against the System also surfaced in the pronouncements of the KPD (German Communist Party). 5No single ideological line of attack doomed the Weimar Republic, but use by an extraordinarily broad range of political groups lent tremendous force to anti-System discourse. Adopted by foes who sometimes agreed on little else, the System was the targets of repeated attacks spread across the German political spectrum and called into question Weimar legitimacy. Analyzing this broad pattern of use raises several tasks. As a prelude to investigating anti-System terminology, it is necessary to map out the patterns of use of the System during the Weimar Republic. The very ability of rival groups to adopt anti-System suggests that the System incorporated varied meanings.Beyond investigating the meaning or meanings of the System, an analysis of anti-System terminology should also explore the appeal and influence of anti-System terminology. Why did such a broad range of groups adopt anti-System discourse, and how did acceptance of anti-System terminology help to discredit the Weimar Republic and designate alternatives for Germany’s future? [End Page 356]Describing Weimar’s perceived failings, anti-System terminology simultaneously provided a partial guide to a presumably-better Germany without the System. The System came to envelop many institutions of German public life, but attention should also be paid to spaces left unoccupied by the System. What, if any, institutions or structures of public life were left untainted by the broad wave of attacks against the System? If the hated System could be swept away, what would be left in its place? It is noteworthy that the many enemies of the System generally desired a strong state.Exploring the effects of broad attacks against the System, analysis of the System should also... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Forms of Life and Cultural EndowmentsVictor Peterson IIYou know, honey, us colored folk is branches without roots and that makes things come round in queer ways.—Zora Neale Hurston (Their Eyes Were Watching God 15)what does it mean when we speak of a form of life? When speaking of a form of life, we consider one different from others by way of its mode of expression, that is, (...) by its means of construction. This interpretation lends itself to a functional analysis of the material put to use and whose operations jointly express the concept we are after. Modes of expression can be plotted between a rhetorical and semantic axis (Gates 48). As such, "[t]he level of connotation of the visual sign, of its contextual reference and positioning in different discursive fields of meaning and association, is the point where already coded signs intersect with the deep semantic codes of a culture and take on additional more active ideological dimensions" (Hall 56). Coordinates within this domain encode signifying practices, revitalizing the traditional concept of signification as a function of what's signified with respect to a signifier. The content of a syntagm in this coordinate system, a point in this plane, indexes its function with respect to others. As such, we will conceive of the content of modes of expression functionally.A function is defined by pairing an element from a domain and another from a sub/co-domain whereby that pair is an element of that function. In this way, we can treat functions as abstract objects. If we treat a domain as what determines the availability of an expression, and a sub/co-domain as representative of its range of application, then the function of applying some proposition maps a movement from a domain of selection to one of composition, that is, its use with respect to others. The function of an expression, then, represents an operation over the possible worlds of its appropriate application (Taylor 201–02, 269, 276). This becomes more interesting when considering assertions whereby one subject is known to be the case for another, a concept that's modeled when a proposition from one is appearing in the object position of another (Fara 65–73). Resultingly, a proposal for an [End Page 26] ontology constituted by modes of interaction rather than identity stipulations to physical entities arises. It follows that if a form of life is understood by way of its mode of expression, then its content is expressed as an ensemble of the functions of its operations. Let this ensemble of functions be called an endowment.There is a pervasive debate in cultural studies that obsesses over proprietary notions as well as the ability to locate an origin. With that in mind, let us consider a coordinate system where there are two perpendicular axes, and we define positions within the space provided at the intersection of lines drawn from each. Each axis is represented by an ordered series of markers. A line drawn from each axis indicates that the coordinates indexed at their intersection is a function of these two markers. This locates an individual at a point in that domain, indexing a relation between the axes framing that space. Therefore, that coordinate-wise space, here a domain of possible expression, is not "empty" as pessimists would claim, but is filled with functional-content, albeit functions yet applied and marked by a point in that plane.Although we are currently speaking of two-dimensional space, the same follows for as many dimensions as we want. A point's location is a function of three values in three dimensions, four in four dimensions, and so on. Forms of life, then, will be comprised of four dimensions. This allows for a space-time conception, wherein joint expressions bend space-time and that space dictates those individuals' possible movements. From this, we construct a geometrical model of space-time represented as a cube composed of two-dimensional slices with these slices extending in a particular direction like cards stacked one on top of the other to model time.We want our conception of a form of life to be spatial. After all, it... (shrink)

Let g be a map defined as the Nisan–Wigderson generator but based on an NP ∩ coNP -function f. Any string b outside the range of g determines a propositional tautology τb expressing this fact. Razborov [27] has conjectured that if f is hard on average for P/poly then these tautologies have no polynomial size proofs in the Extended Frege system EF. We consider a more general Statement that the tautologies have no polynomial size proofs in any propositional proof (...) system. This is equivalent to the statement that the complement of the range of g contains no infinite NP set. We prove that Statement is consistent with Cook' s theory PV and, in fact, with the true universal theory T PV in the language of PV. If PV in this consistency statement could be extended to "a bit" stronger theory then Razborov's conjecture would follow, and if TPV could be added too then Statement would follow. We discuss this problem in some detail, pointing out a certain form of reflection principle for propositional logic, and we introduce a related feasible disjunction property of proof systems.

In this paper architectural forms are presented as symbolic forms issued from the complex semiosis that characterises human cognition (Ferreira (2007, 2010)). Being semiotic objects, these symbolic forms are, consequently, context- dependent_they emerge and have meaning, i.e., they are assigned a functional and/or aesthetic value, in particular physical, social and cultural frameworks. As it happens with all semiotic objects, architectural forms, whatever their nature, are not static but highly interactive. In fact, they act as agents of specific semiotic processes, engaged (...) in a permanent dialectic relationship with the environment they are embedded in. From this dialectics important physical, social, cultural and economic changes frequently arise, redefining this way the original framework for decades to come. As Pallasmaa (2009) points out: “Architecture is existentially rooted, and it expresses fundamental existential experiences, the complex condensation of how it feels to be human being in this world. Architecture grounds and frames existence and creates specific horizons of perception, understanding and identity.” Architecture happens in the context of particular landscapes both natural and man-made, individuating spaces, assigning them an identity, turning the frequently undifferentiated physical environment into “locus”, “place”, “site”, “ort”, definitely contributing to the definition of the mental map that individual minds are able to share collectively. The fundamental role played by architectural forms in the definition of “place” and identity and in the shaping or reshaping of a physical, social and cultural environment is analysed in this paper through a case study that observes the consequences of this dynamics in the development of the social and cultural tissue of a particular city.

The concept of the cortical column refers to vertical cell bands with similar response properties, which were initially observed by Vernon Mountcastle’s mapping of single cell recordings in the cat somatic cortex. It has subsequently guided over 50 years of neuroscientific research, in which fundamental questions about the modularity of the cortex and basic principles of sensory information processing were empirically investigated. Nevertheless, the status of the column remains controversial today, as skeptical commentators proclaim that the vertical cell bands (...) are a functionally insignificant by-product of ontogenetic development. This paper inquires how the column came to be viewed as an elementary unit of the cortex from Mountcastle’s discovery in 1955 until David Hubel and Torsten Wiesel’s reception of the Nobel Prize in 1981. I first argue that Mountcastle’s vertical electrode recordings served as criteria for applying the column concept to electrophysiological data. In contrast to previous authors, I claim that this move from electrophysiological data to the phenomenon of columnar responses was concept-laden, but not theory-laden. In the second part of the paper, I argue that Mountcastle’s criteria provided Hubel Wiesel with a conceptual outlook, i.e. it allowed them to anticipate columnar patterns in the cat and macaque visual cortex. I argue that in the late 1970s, this outlook only briefly took a form that one could call a ‘theory’ of the cerebral cortex, before new experimental techniques started to diversify column research. I end by showing how this account of early column research fits into a larger project that follows the conceptual development of the column into the present. (shrink)

I argue that alternative-denoting expressions interact with their semantic context by taking scope. With an empirical focus on indefinites in English, I show how this approach improves on standard alternative-semantic architectures that use point-wise composition to subvert islands, as well as on in situ approaches to indefinites more generally. Unlike grammars based on point-wise composition, scope-based alternative management is thoroughly categorematic, doesn’t under-generate readings when multiple sources of alternatives occur on an island, and is compatible with standard treatments of binding. (...) Unlike all in situ treatments of indefinites, relying on a true scope mechanism prevents over-generation when an operator binds into an indefinite. My account relies only on function application, some mechanism for scope-taking, and two freely-applying type-shifters: the first is Karttunen’s :3–44, 1977. https://doi.org/10.1007/BF00351935) proto-question operator, aka Partee’s Studies in discourse representation theory and the theory of generalized quantifiers, Foris, Dordrecht, 1986) IDENT, and the second can be factored out of extant approaches to the semantics of questions in the tradition of Karttunen. These type-shifters form a decomposition of LIFT, the familiar function mapping values into scope-takers. Exceptional scope of alternative-generating expressions arises via scopal pied-piping: indefinites take scope over their island, which then itself takes scope. (shrink)

It would be useful to have a category of extensive-form games whose isomorphisms specify equivalences between games. Since working with entire games is too large a project for a single paper, I begin here with preforms, where a “preform” is a rooted tree together with choices and information sets. In particular, this paper first defines the category \, whose objects are “functioned trees”, which are specially designed to be incorporated into preforms. I show that \ is isomorphic to the (...) full subcategory of \ whose objects are converging arborescences. Then the paper defines the category \, whose objects are “node-and-choice preforms”, each of which consists of a node set, a choice set, and an operator mapping node-choice pairs to nodes. I characterize the \ isomorphisms, define a forgetful functor from \ to \, and show that \ is equivalent to the full subcategory of \ whose objects are perfect-information preforms. The paper also shows that many game-theoretic entities can be derived from preforms, and that these entities are well-behaved with respect to \ morphisms and isomorphisms. (shrink)

The standard semantic definition of consequence with respect to a selected set X of symbols, in terms of truth preservation under replacement (Bolzano) or reinterpretation (Tarski) of symbols outside X, yields a function mapping X to a consequence relation ⇒x. We investigate a function going in the other direction, thus extracting the constants of a given consequence relation, and we show that this function (a) retrieves the usual logical constants from the usual logical consequence relations, and (...) (b) is an inverse to—more precisely, forms a Galois connection with—the Bolzano-Tarski function. (shrink)

My aim in this paper is twofold. First, I provide an analysis of the notion of cognitive homology. In contrast with the well-known concept of structural homology in biology—defined as the same structure in different animals regardless of form and function—the notion of cognitive homology captures the idea that the basic cognitive contribution of a given homologous brain structure tends to remain stable over long evolutionary time scales. Second, I argue that this notion provides a powerful conceptual tool (...) for the study of cognition. Since a cognitive homology will often consist of an evolutionarily conserved relationship between a homologous brain structure and its basic cognitive contribution, such structure–function mappings can be conceived as basic building blocks of human cognition.

“There is only one difference between a madman and me. I am not mad.” —Salvador DaliThe romantic notion that mental illness and creativity are linked is so prominent in the public consciousness that it is rarely challenged. So before we continue, let’s nip this in the bud: Mental illness is neither necessary nor sufficient for creativity. The oft-cited studies by Kay Redfield Jamison (1989), Nancy Andreasen (1987), and Arnold Ludwig (1995) showing a link between mental illness and creativity have been (...) criticized on the grounds that they involve small, highly specialized samples with weak and inconsistent methodologies and a strong dependence on subjective and anecdotal accounts (Schlesinger, 2009).To be sure, research does show that many eminent creators – particularly in the arts– had harsh early life experiences (such as social rejection, parental loss, or physical disability) and mental and emotional instability (Ludwig, 1995; Ludwig, 1998; Simonton, 1994). However, this does not mean that mental illness was a contributing factor to their eminence. There are many eminent people without mental illness or harsh early life experiences, and there is very little evidence suggesting that clinical, debilitating mental illness is conducive to productivity and innovation.What’s more, only a few of us ever reach eminence. Beghetto and Kaufman (2007) argue that we can display creativity in many different ways, from the creativity inherent in the learning process (“mini-c”), to everyday forms of creativity (“little-c”) to professional- level expertise in any creative endeavor (“Pro-c”), to eminent creativity (“Big-C”).Engagement in everyday forms of creativity (Richards, 2007) – expressions of originality and meaningfulness in daily life – certainly do not require suffering. Quite the contrary, people who engaged in everyday forms of creativity– such as making a collage, taking photographs, or publishing in a literary magazine– tend to be more open-minded, curious, persistent, positive, energetic, and intrinsically motivated by their activity (Ivcevic, 2007; Ivcevic & Mayer, 2009). Those scoring high in everyday creativity also tend to report feeling a greater sense of well-being and personal growth compared to their classmates who engage less in everyday creative behaviors. Creating can also be therapeutic for those who are already suffering. For instance, research shows that expressive writing increases immune system functioning (Kaufman & Sexton, 2006, Kaufman & Kaufman, 2009), and the emerging field of posttraumatic growth is showing how people can turn adversity into creative growth (Forgeard, 2013; Tedeschi & Calhoun, 2004).So is there any germ of truth to the link between creativity and mental illness? Thelatest research suggests there is something to the link, but the truth is much more nuanced—and we think interesting—than the more romanticized notions of the link.To see the matter clearly, we need to take a step back and consider what we mean by “creativity” and “mental illness” in the first place. While there are many forms of mental illness, this paper focuses on schizophrenia, a family of mental disorders characterized by a severe disconnect from reality, including a tendency to experience thoughts that are divergent, disorganized, and delusional. One aspect of creativity is obviously novelty or originality. Meanwhile, schizophrenic thoughts are more likely to be unique or new. So, by its very nature, schizophrenia disposes one toward satisfying one requirement for creative thought: namely originality.Originality is not sufficient for creativity, however, for as Immanuel Kant (2000) observed long ago, “there can be original nonsense,” as in the word salad of a schizophrenic patient. For a product to be creative it must not only be new but also useful, effective, or valuable in some way (Gaut, 2010; Sternberg & Lubart, 1999; Klausen, 2010). A highly original product might be deemed a symptom of mental illness or an expression of creativity depending on whether or not it is useful. Creativity is maximized when both novelty and utility are simultaneously maximized.These two features – novelty and utility – respectively depend on two cognitive functions: the generation of ideas popping up in conscious thought, and the selection of ideas to be explored, developed, and ultimately expressed or realized in the form of an observable product (cf. Finke et al., 1992). These two cognitive functions map on nicely to the Blind Variation and Selective Retention (BVSR) model of creativity (Campbell, 1960, Jung, 2014, Jung et al., 2013; Simonton, 2011).The more productively one generates ideas (regardless of the extent to which the utilities are initially known), the more likely some of them will be new. The more effectively one selects and develops particular ideas, the more likely some of them will result in something useful. Being creative is similar to mental illness in that it involves a heightened capacity and inclination to produce a large quantity of ideas and associations. What distinguishes the creative person is that she is better able to manage the flood of ideas, selecting the useful ones and developing them effectively while discarding the ones that just too disconnected to reality. This chimes with the oft-quoted remark of scientist, peace activist, and two-time Nobel laureate Linus Pauling: “The way to get good ideas is to get lots of ideas and throw the bad ones away.”Indeed, recent research suggests a link between milder forms of schizophrenia and creativity. In a recent report based on a 40-year study of roughly 1.2 million Swedish people, Simon Kyaga et al. (2013) found that those in scientific and artistic occupations were not more likely to suffer from psychiatric disorders, with the exception of bipolar disorders. So full-blown mental illness did not increase the probability of entering a creative profession (even the exception, bipolar disorder, showed only a small effect of 8%).What was striking, however, was that the siblings of patients with autism and the first-degree relatives of patients with schizophrenia were significantly overrepresented in creative professions. Could it be that the relatives inherited a watered-down version of the mental illness conducive to creativity while avoiding the aspects that are debilitating?Research supports the notion that psychologically healthy biological relatives of people with schizophrenia have unusually creative jobs and hobbies and tend to show higher levels of schizotypal personality traits compared to the general population (Kinney et al. 2001). Schizotypy consists of a constellation of personality traits that are evident to some degree in everyone.Schizotypal traits can be broken down into two types. “Positive” schizotypy includes unusual perceptual experiences, thin mental boundaries between self and other, impulsive nonconformity, and magical beliefs. “Negative” schizotypal traits include cognitive disorganization and physical and social anhedonia (difficulty experiencing pleasure from social interactions and activities that are enjoyable for most people). Daniel Nettle (2006) found that people with schizotypy typically resemble schizophrenia patients much more along the positive schizotypal dimensions (such as unusual experiences) compared to the negative schizotypal dimensions (such as lack of affect and volition).This has important implications for creativity. Mark Batey and Adrian Furnham (2008) found that the unusual experiences and impulsive nonconformity dimensions of schizotypy, but not the cognitive disorganization dimension, were significantly related to self-ratings of creativity, a creative personality (measured by a checklist of adjectives such as “confident,” “individualistic,” “insightful,” “wide interests,” “original,” “reflective,” “resourceful,” “unconventional,” and “sexy”), and everyday creative achievement among thirty-four activities (“written a short story,” “produced your own website,” “composed a piece of music,” and so forth).Recent neuroscience findings further support the link between schizotypy and creative cognition. Hikaru Takeuchi and colleagues (2004) investigated the functional brain characteristics of participants while they engaged in a difficult working memory task. Importantly, none of their subjects had a history of neurological or psychiatric illness, and all had intact working memory abilities. Participants were asked to display their creativity in a number of ways: generating unique ways of using typical objects, imagining desirable functions in ordinary objects and imagining the consequences of “unimaginable things” happening.The researchers found that the more creative the participant, the more they had difficulty suppressing the precuneus while engaging in an effortful working memory task. The precuneus is the area of the Default Network (Buckner et al., 2008; Andrews-Hanna, Smallwood, & Spreng, 2014) that typically displays the highest levels of activation during rest (when a person is not focusing on an external task). The precuneus has been linked to self-consciousness, self-related mental representations, and the retrieval of personal memories (Cavanna & Trimble, 2006). How is this conducive to creativity? According to the researchers, “Such an inability to suppress seemingly unnecessary cognitive activity may actually help creative subjects in associating two ideas represented in different networks.” Whitfield-Gabrieli et al., 2009 found that a similar inability to deactivate the precuneus among schizophrenic individuals and their relatives. Which raises the intriguing question: what happens if we directly compare the brains of creative people against the brains of people with schizotypy? A recent study by Fink et al., 2014 sheds some light on this question. Consistent with earlier research, they found an association between the ability to come up with original ideas and the inability to suppress activation of the precuneus during creative thinking. As the researchers note, these findings are consistent with the idea that more creative people include more events/stimuli in their mental processes than less creative people. But crucially, they found that those scoring high in schizotypy showed a similar pattern of brain activations during creative thinking as the highly creative participants. This supports the idea that overlapping mental processes are implicated in both creativity and psychosis proneness.Therefore, it seems that the key to creative cognition is opening up the flood gates and letting in as much information as possible. Because you never know: sometimes the most bizarre associations can turn into the most productively creative ideas. This idea is consistent with recent research on latent inhibition (Kaufman, 2009). Latent inhibition is a filtering mechanism that we share with other animals and it is tied to the neurotransmitter dopamine (Lubow & Weiner, 2010). A reduced latent inhibition allows us to treat something as novel, no matter how many times we’ve seen it before and tagged it as irrelevant. Prior research shows a link between reduced latent inhibition and schizophrenia. But more recent research also shows a link to creativity. Carson, Peterson, & Higgins (2003) found that the most eminent creative achievers among a sample of Harvard undergrads were seven times more likely to have reduced latent inhibition. As Carson (2011) points out in her “Shared Vulnerability Model,” mental processes such as reduced latent inhibition, preference for novelty, and hyperconnectivity can “enlarge the range and depth of stimuli available in conscious awareness to be manipulated and combined to form novel and original ideas.” Extreme levels of these factors make one vulnerable to severely disordered thinking. But they can be mitigated and challenged in productively if one has protective factors, such as enhanced fluid reasoning, working memory, cognitive inhibition, and cognitive flexibility (Carson, 2011; Kuszewski, 2009).Another protective factor may lie within the openness to experience domain, a broad personality domain reflecting the tendency toward cognitive exploration (DeYoung, in press). Peterson & Carson (2000) and Peterson, Smith, & Carson (2002) found that students with reduced latent inhibition scored higher in openness to experience. But while openness to experience is consistently associated with creativity (see Kaufman, 2013), this personality domain can also be meaningfully separated into distinct (but correlated) subtraits of Openness to Experience and Intellect (DeYoung, in press; DeYoung, Quilty, & Peterson, 2007). Openness to Experience reflects cognitive engagement with sensory and perceptual information, whereas Intellect reflects cognitive engagement with abstract and semantic information, primarily through reasoning. While Intellect is associated with IQ, executive functioning, and intellectual engagement, Openness is associated with fantasy-proneness, schizotypy, absorption, delusional ideation, and the tendency to make connections and see patterns that don’t actually exist (DeYoung, Grazioplene, & Peterson, 2012; Kaufman, 2013; Menon et al., 2013; Chmielewski et al., 2014). Indeed, Intellect is negatively associated with positive schizotypy and delusional ideation (Menon, Quilty, et al., 2012).Therefore, the combination of Openness and Intellect may be crucial to maintaining high levels of creative production (DeYoung, Grazioplene, & Peterson, 2012). The proper balance most likely differs by domain. There is emerging evidence across diverse samples, ages, and occupations that Openness is associated with creative achievement in the arts, whereas Intellect is associated with creative achievement in the sciences (Kaufman, 2013; Kaufman et al., under revision). This is consistent with research suggesting that schizotypy is associated with verbal and artistic creativity (Beaussart, Kaufman, & Kaufman, 2012; Del Guidice et al., 2010) whereas the autism spectrum is associated with technical-scientific interests and careers (Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001; Crespi & Badcock, 2008). Nevertheless, recent research suggests that creative cognition draws on both the executive functioning that is tied to Intellect and the associative divergence that is associated with Openness (Beaty et al., 2014; Benedek et al., 2014; Jung, 2014; Nusbaum, & Silvia, 2011). Which brings us to the real link between creativity and mental illness. The latest research suggests that mental illness (particularly schizophrenia spectrum disorders) is most conductive to creativity indirectly, by opening the mind and increasing the probability that ideas will be original. Whether the idea is creative, however, also depends on the protective intellectual factors (and autistic-like traits) necessary to steer the chaotic storm. (shrink)

A $\Pi _{1}^{0}$ class is the set of paths through a computable tree. Given classes P and Q, P is Medvedev reducible to Q, P ≤M Q, if there is a computably continuous functional mapping Q into P. We look at the lattice formed by $\Pi _{1}^{0}$ subclasses of 2ω under this reduction. It is known that the degree of a splitting class of c.e. sets is non-branching. We further characterize non-branching degrees, providing two additional properties which guarantee non-branching: (...) inseparable and hyperinseparable. Our main result is to show that non-branching iff inseparable if hyperinseparable if homogeneous and that all unstated implications do not hold. We also show that inseparable and not hyperinseparable degrees are downward dense. (shrink)

BackgroundPatients with chronic conditions are less physically active than the general population despite knowledge of positive effects on physical and mental health. There is a variety of reasons preventing people with disabilities from achieving levels of physical activities resulting in health benefits. However, less is known about potential facilitators and barriers for physical activity in people with severe movement impairments. The aim of this study was to identify obstacles and facilitators of PA in individuals with severe disabilities.Materials and methodsUsing a (...) qualitative approach to explore individuals’ subjective perspectives in depth, five community-dwelling adults living with chronic mobility impairments after stroke that restrict independent PA were interviewed. A semi structured topic guide based on the theoretical domains framework was utilized. The interview data was analyzed thematically, and the theoretical domains framework constructs were mapped onto the main and sub-categories.ResultsThe six main categories of facilitators and barriers along the capability, opportunity, motivation–behavior framework were: physical capabilities, psychological capabilities, motivation reflective, motivation automatic, opportunity physical, and opportunity social. The physical capabilities to independently perform PA were variable between participants but were not necessarily perceived as a barrier. Participants were highly motivated to maintain and/or increase their abilities to master their everyday lives as independently as possible. It became clear that a lack of physical opportunities, such as having access to adequate training facilities can present a barrier. Social opportunities in the form of social support, social norms, or comparisons with others can act as both facilitators and barriers.ConclusionWhile confirming known barriers and facilitators that impact the ability of individuals with functional limitations to be active, the findings highlight the need and opportunities for comprehensive service models based on interdisciplinary collaborations.
