Subject and Aesthetic Interface - an inquiry into transformed subjectivities

The present PhD-thesis seeks new definitions of human subjectivity in an age of technoscience and a networked, globalized, Information Society. The perspective presented relates to Philosophy of Science, which includes the Human, the Natural, the Social and the Life Sciences. The project is directed at addressing, and aims to participate in, the further development of Philosophy of Science, or rather, the philosophy of knowing, which leaves a perspective broader than that of science. Methodologically, I combine readings of technoetic artworks, which I approach from a hermeneutical-semiotic perspective, with transdisciplinary research into existing theory concerning the human subject. These readings form my case studies. I keep a particular focus on holistic biophysics (Mae Wan Ho, James Oschman, Marko Bischof). Furthermore, Søren Brier's cybersemiotic theory of communication, cognition and consciousness, which combines a cybernetic-autopoietic and a Peircean semiotic perspective, plays a central role in the project. The project has three parts. Part one contextualizes the study within philosophy of science. It discusses relevant epistemologies, and places the case studies in an art categorical context. It further discusses the philosophical problems involved in writing an academic thesis in the form of a linear, argumentative, critical style, and how it affects the process of meaning making in a way that has consequences to my research. The second part consists of four case studies, each under an overall theme, which applies to the question of human subjectivity. Here I build the concept Extended Sentience, and the concept of an Ideal User. The Ideal User functions as a conceptual frame, which allows me to gradually add more elements to a theory of an altered human subject and knower. The third part presents new ontologies under three basic themes: Time and Relativity, The Life Cycles of Metaphors, and Logos Philosophy and Virtual Grids. These ontologies strongly affect ways of interpretation made in part one and two. Part Three allows more space to my subjective thought processes, which will take precedence over the literature applied. Thus, I, as a post-objective subject observer, will become more transparent. Finally, I will seek an overall conclusion to the project, which should clarify areas where it is evident that the human subject must be reconsidered at a pre-scientific level. It is my thesis that the foundation for human knowledge generation is changing drastically today, and that it has become crucial to reconsider a common understanding of what constitutes the human knower

Functional imaging studies of visual-auditory integration in man.

This thesis investigates the central nervous system's ability to integrate visual and auditory information from the sensory environment into unified conscious perception. It develops the possibility that the principle of functional specialisation may be applicable in the multisensory domain. The first aim was to establish the neuroanatomical location at which visual and auditory stimuli are integrated in sensory perception. The second was to investigate the neural correlates of visual-auditory synchronicity, which would be expected to play a vital role in establishing which visual and auditory stimuli should be perceptually integrated. Four functional Magnetic Resonance Imaging studies identified brain areas specialised for: the integration of dynamic visual and auditory cues derived from the same everyday environmental events (Experiment 1), discriminating relative synchronicity between dynamic, cyclic, abstract visual and auditory stimuli (Experiment 2 & 3) and the aesthetic evaluation of visually and acoustically perceived art (Experiment 4). Experiment 1 provided evidence to suggest that the posterior temporo-parietal junction may be an important site of crossmodal integration. Experiment 2 revealed for the first time significant activation of the right anterior frontal operculum (aFO) when visual and auditory stimuli cycled asynchronously. Experiment 3 confirmed and developed this observation as the right aFO was activated only during crossmodal (visual-auditory), but not intramodal (visual-visual, auditory-auditory) asynchrony. Experiment 3 also demonstrated activation of the amygdala bilaterally during crossmodal synchrony. Experiment 4 revealed the neural correlates of supramodal, contemplative, aesthetic evaluation within the medial fronto-polar cortex. Activity at this locus varied parametrically according to the degree of subjective aesthetic beauty, for both visual art and musical extracts. The most robust finding of this thesis is that activity in the right aFO increases when concurrently perceived visual and auditory sensory stimuli deviate from crossmodal synchrony, which may veto the crossmodal integration of unrelated stimuli into unified conscious perception

A COGNITIVE APPROACH TO PHONOLOGY: EVIDENCE FROM SIGNED LANGUAGES

This dissertation uses corpus data from ASL and Libras (Brazilian Sign Language), to investigate the distribution of a series of static and dynamic handshapes across the two languages. While traditional phonological frameworks argue handshape distribution to be a facet of well-formedness constraints and articulatory ease (Brentari, 1998), the data analyzed here suggests that the majority of handshapes cluster around schematic form-meaning mappings. Furthermore, these schematic mappings are shown to be motivated by both language-internal and language-external construals of formal articulatory properties and embodied experiential gestalts. Usage-based approaches to phonology (Bybee, 2001) and cognitively oriented constructional approaches (Langacker, 1987) have recognized that phonology is not modular. Instead, phonology is expected to interact with all levels of grammar, including semantic association. In this dissertation I begin to develop a cognitive model of phonology which views phonological content as similar in kind to other constructional units of language. I argue that, because formal units of linguistic structure emerge from the extraction of commonalities across usage events, phonological form is not immune from an accumulation of semantic associations. Finally, I demonstrate that appealing to such approaches allows one to account for both idiosyncratic, unconventionalized mappings seen in creative language use, as well as motivation in highly conventionalized form-meaning associations

Mental content : consequences of the embodied mind paradigm

The central difference between objectivist cognitivist semantics and embodied cognition consists in the fact that the latter is, in contrast to the former, mindful of binding meaning to context-sensitive mental systems. According to Lakoff/Johnson's experientialism, conceptual structures arise from preconceptual kinesthetic image-schematic and basic-level structures. Gallese and Lakoff introduced the notion of exploiting sensorimotor structures for higherlevel cognition. Three different types of X-schemas realise three types of environmentally embedded simulation: Areas that control movements in peri-personal space; canonical neurons of the ventral premotor cortex that fire when a graspable object is represented; the firing of mirror neurons while perceiving certain movements of conspecifics. ..

Beyond the Whorfs of Dover: A Study of Balinese Interpretive Practices

Scholars generally assume that current Euro-American theory is both necessary and sufficient to understand other societies. Analyzing the presuppositions of linguistic and anthropological models indicates however that they are fatally flawed. Examining Balinese practices of speaking and understanding others shows they work with a consistently pragmatic approach with coherent modes of interrogating situated utterances. Close study of examples highlights how far existing theories from truth-conditional semantics to speech act theory not only fail to appreciate what is said and done, but insulate themselves from realizing this. So the many studies of Balinese ‘symbolism’ are only possible by failing to listen to what people say. According to Balinese, speech is inseparable from other acts, so meaning can only be judged from its consequences. If other people have diverse ways of speaking, acting and understanding, should we not finally lay aside our comfortable hegemony and inquire critically what is going on

Multisensory learning in adaptive interactive systems

The main purpose of my work is to investigate multisensory perceptual learning and sensory integration in the design and development of adaptive user interfaces for educational purposes. To this aim, starting from renewed understanding from neuroscience and cognitive science on multisensory perceptual learning and sensory integration, I developed a theoretical computational model for designing multimodal learning technologies that take into account these results. Main theoretical foundations of my research are multisensory perceptual learning theories and the research on sensory processing and integration, embodied cognition theories, computational models of non-verbal and emotion communication in full-body movement, and human-computer interaction models. Finally, a computational model was applied in two case studies, based on two EU ICT-H2020 Projects, "weDRAW" and "TELMI", on which I worked during the PhD

Concepts and analogies in cybernetics: Mathematical investigations of the role of analogy in concept formation and problem solving; with emphasis for conflict resolution via object and morphism eliminations

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.We address two problematic areas of cybernetics; nam. Analogical Problem Solving (APS) and Analogical Learning (AL). Both these human faculties do unquestionably require Intelligence. In addition, we point out that shifting of representations is the main unified theme underlying these two intellectual tasks. We focus our attention on the formulation and clarification of the notion of analogy, which has been loosely treated and used in the literature; and also on its role in shifting of representations. We describe analogizing situations in a new representational scheme, borrowed from mathematics and modified and extended to cater for our targets. We call it k-structure, closely resembling semantic networks and directed graphs; the main components of it are the so-called objects and morphisms. We argue and substantiate the need for such a representation scheme, by analysing what its constituents stand for and by cataloguing its virtues, the main one being its visual appeal and its mathematical clarity, and by listing its disadvantages when it is compared to other representation systems. Emphasis is also given to its descriptive power and usefulness by implementing it in a number of APS and AL situations. Besides representation issues, attention is paid to intelligence mechanisms which are involved in APS and AL. A cornerstone in APS and a fundamental theme in AL is the 'skeletization of k-structures'. APS is conceived as 'harmonization of skeletons'. The methodology we develop involves techniques which are computer implemented and extensively studied in theoretic terms via a proposed theory for extended k-structures. To name but a few: 1. 'the separation of the context of a concept from the concept itself', based on the ideas of k-opens and k-spaces; 2, 'object and morphism elimination' of a controversial nature; and 3. 'conflict or deadlock or dilemma resolution' which naturally arises in a k-structure interaction. The overall system, is then applied to capture the essence of EVANS' (1963) analogy-type problems and WINSTOM (1970) learning-type situations. In our attempt not to be too informal, we use basic notions and terminology from abstract Algebra, Topology and Category theory. We rather tend to be "non-logical" (analogical) in EVANS' and WINSTON's sense; "non-numeric", in MESAROVIC (1970) terms (we rather deal with abstract conceptual entities); "non-linguistic" (we do not touch natural language); and "non-resolution" oriented, in the sense of BLEDSOE (1977). However, we give hints sometimes about logical deductive axiomatic systems, employing First Order Predicate Calculus (FOPC); and about semiotics, by which we denote syntactic-semantic-pragmatic features of our system and issues of the problem domains it is acting upon. We believe in what we call: shift from the traditional 'Heuristic search paradigm' era to the 'Analogy-paradigm' era underlying Artificial Intelligence and Cybernetics. We justify this merely by listing a number of A. I. works, which employ, in some way or another, the concept of analogy, over the last fifteen years or so, where a noticeable peak is obvious during the last years and especially in 1977. Finally, we hope that if the proposed conceptual framework and techniques developed do not straightforwardly constitute some kind of platform for Artificial Intelligence, at least it would give some insights into and illuminate our understanding of the two most fundamental faculties the human brain is occupied with; namely problem solving and learning

The Resemblance Structure of Natural Kinds: A Formal Model for Resemblance Nominalism

278 p.The aim of this thesis is to better understand the ways natural kinds are related to each other by species-genus relations and the ways in which the members of the kind are related to each other by resemblance relations, by making use of formal models of kinds. This is done by first analysing a Minimal Conception of Natural Kinds and then reconstructing it from the ontological assumptions of Resemblance Nominalism. The questions addressed are:(1) What is the external structure of kinds' In what ways are kinds related to each other by species-genus relations'(2) What is the internal structure of kinds' In what sense are the instances of a kind similar enough to each other'According to the Minimal Conception of Kinds, kinds have two components, a set of members of the kind (the extension) and a set of natural attributes common to these objects (the intension). Several interesting features of this conception are discussed by making use of the mathematical theory of concept lattices. First, such structures provide a model for contemporary formulations of syllogistic logic. Second, kinds are ordered forming a complete lattice that follows Kant's law of the duality between extension and intension, according to which the extension of a kind is inversely related to its intension. Finally, kinds are shown to have Aristotelian definitions in terms of genera and specific differences. Overall this results in a description of the specificity relations of kinds as an algebraic calculus.According to Resemblance Nominalism, attributes or properties are classes of similar objects. Such an approach faces Goodman's companionship and imperfect community problems. In order to deal with these, a specific nominalism, namely Aristocratic Resemblance Nominalism, is chosen. According to it, attributes are classes of objects resembling a given paradigm. A model for it is introduced by making use of the mathematical theory of similarity structures and of some results on the topic of quasianalysis. Two other models (the polar model and an order-theoretic model) are considered and shown to be equivalent to the previous one.The main result is that the class of lattices of kinds that a nominalist can recover uniquely by starting from these assumptions is that of complete coatomistic lattices. Several other related results are obtained, including a generalization of the similarity model that allows for paradigms with several properties and properties with several paradigms. The conclusion is that, under nominalist assumptions, the internal structure of kinds is fixed by paradigmatic objects and the external structure of kinds is that of a coatomistic lattice that satisfies the Minimal Conception of Kinds

An investigation into the visualisation of the transmission network by national grid controllers

Faculty of Engineering & Built Environment, School of Electrical & Infomation Engineering, MSC DissertationThe South African electrical utility,ESKOM, is one of the largest in the world with 40 GW capacity, worth R 965 billion, and an annual income of R 33 billion. The people responsible for the voltage control of the ESKOM transmission grid are highly skilled voltage controllers. An investigation was conducted to identify what constitutes their expertise. This is a ultidisciplinary research project that incorporates the fields of Power System Engineering, Industrial and Cognitive Psychology and Neuro-Linguistic Programming. Observations of the voltage controllers at work were carried out followed by in-depth interviews in order to identify, their Mental Control Strategies, Power System Visualization techniques, and Mental Models. Expert and novice voltage controllers were included in the research as well as one in-house Man Machine Interface (MMI) developer. Some of the main findings are: ·The sophisticated mental strategies that allow controllers to simplify the overabundance of data presented to them. ·The subconsciously created vivid mental imagery that they use to make fast intuitive decisions. Having obtained the above information, MMI design and human controller training can be optimised
