Relationalism in the face of hallucinations / Le relationnalisme face aux hallucinationsLocatelli, Roberta 15 December 2016 (has links)
Le relationnalisme affirme que le caractère phénoménal de la perception est en partie constitué par les objets que l’on voit. Malgré son attrait intuitif, il est souvent rejeté en vertu de l'argument de l'hallucination. L'objectif de cette thèse est de défendre le relationnalisme. L'argument fait valoir que, puisque le relationnalisme ne peut être vrai pour les hallucinations, il doit forcément être faux pour les perceptions aussi. En cela, l'argument repose sur le principe de l’indiscernabilité (IND), affirmant que deux expériences qui sont introspectivement indiscernables les unes des autres ont le même caractère phénoménal. Je considère et rejette les autres versions de l'argument qui ne reposent pas sur l'IND. Bien que largement accepté, aucun support satisfaisant pour l'IND n'a encore été présenté. Dans cette thèse, je soutiens que la défense de l'IND requiert que l’on entende la notion d’indiscernabilité employée dans l'IND en un sens impersonnel. Ensuite, j’identifie ce qui motive l'IND : l'intuition que, en vertu de sa superficialité, la nature d'un caractère phénoménal doit être accessible par l'introspection, de concert avec l’idée qu’il est impossible de nier l'IND sans nier par là même la superficialité des caractères phénoménaux.Je soutiens que le relationnaliste peut nier l'IND tout en préservant la superficialité des caractères phénoménaux en adoptant une thèse négative de l'hallucination et en reconsidérant la nature de la relation entre le caractère phénoménal d’une expérience et l’accès introspectif qu'il peut y avoir. / Relationalism claims that the phenomenal character of perception is constituted by the obtaining of a non-representational psychological relation to mind-independent objects. Although relationalism provides what seems to be the most straight forward and intuitive account of how experience strikes us introspectively, it is very often believed that the argument from hallucination shows that the view is untenable. The aim of this thesis is to defend relationalism against the argument from hallucination. The argument claims that the phenomenal character of hallucination and perception deserves the same account, and that relationalism cannot be true for hallucinations, therefore relationalism must be rejected. This argument relies on the Indistinguishability Principle (IND), the claim that two experiences that are introspectively indistinguishable from each other have the same phenomenal character. Before assessing the plausibility of this principle, I first consider and dismiss versions of the argument which wouldn’t depend on IND.Although widely accepted, no satisfactory support for IND has been presented yet. In this thesis I argue that defending IND requires that we understand the notion of ‘indiscriminability’ employed in IND in an impersonal sense. I then identify what underwrites IND: the intuition that, in virtue of its superficiality, the nature of a phenomenal character must be accessible through introspection, together with the claim that it is not possible to deny IND without denying the superficiality of phenomenal characters too.I argue that the relationalist can deny IND while preserving the superficiality of phenomenal characters. This can be done by adopting a negative view of hallucination and an account of introspection whereby the phenomenal character doesn’t exist independently of one’s introspective awareness of it and where having introspective access to our experience depends on our perceptual access to the world.

Reflection and Introspection in the Film Scores of Thomas NewmanOden, Chelsea 27 October 2016 (has links)
The most transformative moments in life cause us to look both backward (reflection) and inward (introspection). Likewise, reflective and introspective moments in film often align with important plot points. Separating music and dialogue from the rhythms of the image, these moments suspend time, creating a distinct temporality for the character(s) and the viewer to observe the past and the present in juxtaposition. The music of film composer Thomas Newman brings to life some of the most beautiful reflective and introspective moments in cinema. In this thesis, I approach Newman’s understudied, but highly successful film scores from narrative, musical, and audiovisual perspectives. Recognizing time as a linear common denominator between the multimedia elements of film, I examine case study scenes in Little Women (1994), The Shawshank Redemption (1994), and American Beauty (1999). Additionally, I present Kofi Agawu’s method of generative analysis as a tool well-suited to Newman’s unique harmonic language.

Subjective Experiences in Conflict TasksQuestienne, Laurence 30 October 2017 (has links)
While performing a task, we feel cognitive and affective conscious experiences that we can subjectively evaluate. For instance, we can feel that we perform well or badly, or that the task is easy or difficult, etc. These subjective experiences could have an influence on behavioural adaptation. In the current thesis, we aimed to understand how these experiences emerge and how they are related to behavioural adaptation. In a first experimental study, we investigated, in the context of a conflict task, the relationship between the experience of conflict and the Gratton effect. This effect is considered as a hallmark of cognitive control. We replicated and generalised previous results (Desender, Van Opstal & Van den Bussche, 2014) that showed that metacognitive experiences of conflict are related to the Gratton effect. In the second study, we demonstrated that people are able to focus on highly specific aspects of their phenomenal experience (i.e. visual vs. motor conflict) that are usually confounded in conflict tasks. In the third and the fourth experimental study of the thesis, we focused on the experience of “urge-to-err”, i.e. the subjective feeling that one is about to make an error, even if the final response is correct. Using electromyography, we showed that this experience is highly determined by features of motor performance. We also demonstrated that subjective experiences of the urge-to-err result from several features that can be objectified and disentangled. Finally, we studied the temporal dynamics of the experience of urge-to-err by analysing the electroencephalographic markers that relate to judgements of urge-to-err. Results show that these judgements are rather blind to pre-response processing, and are mainly supported by tardive processes related to response evaluation.In sum, through different studies using behavioural, electromyographic and electroencephalographic measures, the current thesis discloses the building blocks of metacognitive experiences in the context of conflict task and uncover their mechanisms. This work also contributes to a better understanding of the relationship between subjective experiences and behavioural adaptation. / Lorsque nous réalisons une tâche, nous ressentons consciemment des expériences cognitives et affectives que l’on peut subjectivement évaluer. Par exemple, nous pouvons avoir l’impression que notre performance est plus ou moins bonne, ressentir que la tâche est plus ou moins difficile, etc. Ces expériences subjectives pourraient avoir une influence sur nos adaptations comportementales. Dans cette thèse de doctorat, nous avions pour objectif de comprendre l’émergence de ces expériences subjectives et leurs rôles dans nos comportements adaptatifs. Dans une première étude expérimentale, nous avons investigué la relation entre les expériences de conflit et l’effet Gratton dans le contexte des tâches de conflit. L’effet Gratton est considéré comme une signature comportementale de mécanismes de contrôle cognitif. Nous avons répliqué et généralisé de précédents résultats (Desender, Van Opstal & Van den Bussche, 2014) qui avaient montré que les expériences métacognitives du conflit sont liées à l’effet Gratton. Dans une seconde étude, nous avons montré que les participants sont capables de se concentrer sur des aspects très spécifiques de leur expérience phénoménale, ces aspects (conflit visuel et conflit moteur) étant habituellement confondus dans des tâches de conflit. Dans la troisième et quatrième étude de cette thèse, nous nous sommes concentrés sur l’expérience de « urge-to-err », c’est à dire le sentiment subjectif d’être sur le point de faire une erreur, bien que la réponse donnée soit finalement correcte. En utilisant des enregistrements électromyographiques, nous avons montré que cette expérience subjective résulte d'une combinaison de différents aspects de la tâche, dont en particulier la performance motrice. Finalement, nous avons étudié le décours temporel de l’émergence de l’expérience de « urge-to-err » en analysant les marqueurs électroencéphalographiques liés à cette expérience. Les résultats montrent que notre expérience subjective de « urge-to-err » est aveugle aux traitements cognitifs qui ont lieu avant la réponse motrice. Cette expérience est principalement sous-tendue par des traitements tardifs liés à l’évaluation de la réponse. En résumé, à travers différentes études utilisant des mesures comportementales, électromyographiques et électroencéphalographiques, la présente thèse révèle les éléments constitutifs des expériences métacognitives dans le contexte de tâches de conflit. Ce travail contribue également à une meilleure compréhension de la relation entre expériences subjectives et comportements adaptatifs. / Doctorat en Sciences psychologiques et de l'éducation / info:eu-repo/semantics/nonPublished

Svoboda vůle a přístup k informacím o vlastních intencích / Freedom of will and access to informations about one's own intentionsHavlíček, Ondřej January 2011 (has links)
This diploma thesis deals with the problem of free will and the reliability of an introspective access to action intentions. The traditional questions of free will, responsibility and determinism are currently receiving a lot of attention due to the advances in cognitive sciences. Because of various scientific findings, many authors claim that free will is just an illusion. The purpose of this study is to discuss traditional conceptualization of this topic and point out its problems. As an alternative, I am trying to suggest a compatibilistic theory of freedom and responsibility, which is internally coherent and compatible with scientific evidence. The core of my thesis is a replication and modification of a recent experimental study, investigating voluntary decision-making and an introspective access to one's own intentions. The participants of the experiment performed reflexive actions which they misjudged as intentional. The goal of the theoretical part of my thesis has been accomplished on the basis of examining a voluminous foreign literature. The method involves a philosophical analysis of concepts with an emphasis on contemporary scientific findings. In the empirical part of my work, results were obtained in a cognitive-psychological experiment involving reaction time and evoked potential data acquisition and their analysis. First, a discussion of concepts relevant to the problem of free will is undertaken. An explication of the most significant experiments that question traditional intuitions about the human mind and free will is then given. A detailed description of my experiment follows, including its results and implications. Finally, conclusions about the nature of free will and responsibility are made together with certain suggestions for both the criminal justice system and everyday situations. Although I base the theoretical part of my thesis on the results of many authors, I contribute to it to a substantial degree with my own opinions and arguments. The empirical study is the most significant contribution of mine as its realization demanded i.a. a development of a stimulus presentation software, execution of the experimental tasks with a relatively large number of subjects and a mathematical and statistical evaluation of the acquired data.

Digital forensics - Performing virtual primary memory extraction in cloud environments using VMIHjerpe, David, Bengtsson, Henrik January 2018 (has links)
Infrastructure as a Service and memory forensics are two subjects which have recently gained increasing amounts of attention. Combining these topics poses new challenges when performing forensic investigations. Forensics targeting virtual machines in a cloud environment is problematic since the devices are virtual, and memory forensics are a newer branch of forensics which is hard to perform and is not well documented. It is, however an area of utmost importance since virtual machines may be targets of, or participate in suspicious activity to the same extent as physical machines. Should such activity require an investigation to be conducted, some data which could be used as evidence may only be found in the primary memory. This thesis aims to further examine memory forensics in cloud environments and expand the academic field of these subjects and help cloud hosting organisations. The objective of this thesis was to study if Virtual Machine Introspection is a valid technique to acquire forensic evidence from the virtual primary memory of a virtual machine. Virtual Machine Introspection is a method of monitoring and analysing a guest via the hypervisor. In order to verify whether Virtual Machine Introspection is a valid forensic technique, the first task was to attempt extracting data from the primary memory which had been acquired using Virtual Machine Introspection. Once extracted, the integrity of the data had to be authenticated. This was done by comparing a hash sum of a file located on a guest with a hash sum of the extracted data. The experiment showed that the two hashes were an exact match. Next, the solidity of the extracted data was tested by changing the memory of a guest while acquiring the memory via Virtual Machine Introspection. This showed that the solidity is heavily compromised because memory acquisition process used was too slow. The final task was to compare Virtual Machine Introspection to acquiring the physical memory of the host. By setting up two virtual machines and examining the primary memory, data from both machines was found where as Virtual Machine Introspection only targets one machine, providing an advantage regarding privacy.

Introversion And Autism: A Conceptual Exploration Of The Placement Of Introversion On The Autism SpectrumGrimes, Jennifer 01 January 2010 (has links)
The conceptualization of the personality construct of introversion has been problematic since the term's inception due to the complexity and seemingly self-contradictory nature of the collection of attributes of which it is comprised. To advance the understanding of introversion, I propose that it is a continuous segment of the non-clinical part of the autism spectrum, and that it is not the same as the inverse of extraversion. When introversion and autism are placed on the same continuum, the nature of the relationship of the traits becomes more apparent, and new possibilities are available for exploration of both autism and introversion. This review of literature traces the origins and development of the concept of introversion and places it on the autism spectrum, demonstrating the apparent synonymous nature of the traits despite varying degrees of severity in expression. The current factorial structure of introversion demonstrates how autistic features interact to produce the personality dimension. Other factors, including genetic predisposition, relationships to the clinical and non-clinical symptoms of schizophrenia spectrum expression, and neurological findings that support the correlation will be considered. Finally, suggestions for future research and possible theoretical and empirical implications and applications are explored.

'The divine voice within us' : the reflective tradition in the novels of Jane Austen and George EliotPimentel, A. Rose January 2011 (has links)
This thesis argues that a ‘tradition of moral analysis’ between Jane Austen and George Eliot — a common ground which has been identified by critics from F.R. Leavis to Gillian Beer, but never fully explored — can be illuminated by turning to what this thesis calls ‘the reflective tradition’. In the eighteenth century, ideas about reflection provided a new and influential way of thinking about the human mind; about how we come to know ourselves and the world around us through the mind. The belief in the individual to act as his/her own guide through the cultivation of a reflective mind and attentiveness to a reflective voice emerges across a wide range of discourses. This thesis begins with an examination of reflection in the philosophy, children’s literature, novels, poetry, educational tracts and sermons that would have been known to Austen. It then defines Austen’s development of reflective dynamics by looking at her six major novels; finally, it analyzes Middlemarch to define Eliot’s proximity to this aspect of Austen’s art. The thesis documents Eliot’s reading of Austen through the criticism of G. H. Lewes to support a reading of Eliot’s assimilation of an Austenian attention to mental processes in her novels. Reflection is at the heart of moral life and growth for both novelists. This thesis corrects a tendency in Austen’s reception to focus on the mimetic aspect of her art, thereby overlooking the introspective sense of reflection. It offers new insights into Austen’s and Eliot’s work, and it contributes to an understanding of the development of the realist novel and the ethical dimension in the role of the novel reader.

La marque Apple comme ressource dans la construction de l'identité familiale : une approche auto-ethnographique / The Apple brand as a resource to construct family identity : an autoethnographic approachBillon, Dominique 09 January 2017 (has links)
La recherche se situe dans le courant de la Consumer Culture Theory dans la lignée de travaux récents visant à comprendre les relations collectives à une marque. La marque n’est plus pensée comme une « chose » fabriquée exclusivement par l’entreprise, mais comme un processus dans lequel sont impliqués de multiples acteurs échappant souvent au contrôle de l’entreprise. La thèse investigue comment la marque s’insère et est insérée dans les réseaux de relations, les pratiques et les représentations des consommateurs au sein de leur famille sur trois générations. La méthodologie est basée sur l’auto-ethnographie, une méthode rarement utilisée dans la recherche sur la marque. Le dispositif déployé permet une compréhension fine des interactions et stratégies des personnes, grâce à la prise en compte du temps long (trente ans) et à la multivocalité. La thèse étend le concept de « cultural branding » au niveau de la famille, en introduisant le concept de « réseau familial de marque » qui rend compte de la façon dont familles et marques s’imbriquent dans notre société. En décrivant une réalité différente des principes de gestion de la marque dans lesquels l’entreprise est supposée influencer un consommateur isolé, la thèse renouvelle les approches conventionnelles de la relation marque-consommateur et complète les approches communautaires de la marque. / This thesis is situated in the research stream called Consumer Culture Theory (CCT), in line with recent research trying to understand the collective relationships to a brand. The brand is no more understood as a “thing” created by a company (brand as a name), but as a process (branding as a verb) in which many participants play different roles, frequently outside the control of the company. The thesis investigates how the brand becomes embedded in the networks of relationships, practices and discourses within a family through three generations. The methodology is based on an autoethnography, a method rarely used in consumer and branding research. This approach enables a deep understanding of the interactions and strategies of people, taking a long-term perspective (thirty years) and considering the multivocality. This thesis is an extension of cultural branding at the family level, by introducing the concept of « brand family network », which reports how families and brands are embedded in our society. The thesis describes a reality different from the traditional principles of brand management, based on the idea that the company is supposed to influence a single consumer. By doing so, it extends the understanding of consumer-brand relationships, and complement the approach of the brand communities.

Uncommon knowledgeLederman, Harvey January 2014 (has links)
This dissertation collects four papers on common knowledge and one on introspection principles in epistemic game theory. The first two papers offer a sustained argument against the importance of common knowledge and belief in explaining social behavior. Chapters 3 and 4 study the role of common knowledge of tautologies in standard models in epistemic logic and game theory. The first considers the problem as it relates to Robert Aumann’s Agreement Theorem; the second (joint work with Peter Fritz) studies it in models of awareness. The fifth paper corrects a claimed Agreement Theorem of Geanakoplos (1989), and exploits the corrected theorem to provide epistemic conditions for correlated equilibrium and Nash equilibrium.

Filtros para objetos / Filters for objectsGuimaraes, Jose de Oliveira 22 April 1996 (has links)
Esta tese propõe cinco construções para linguagens orientadas a objetos. Algumas delas podem ser implementadas por meio de pré-processadores. Estas construções são: visão de classe, adaptador, extensão de classe, Shell dinâmico e extensão dinâmica. Todas elas são baseadas no conceito de filtro, que e um objeto que intercepta as mensagens enviadas a um outro objeto. Visão de classe permite corrigir interpretações incorretas da semântica de uma classe no código de outras classes. Um filtro é usado para traduzir as mensagens para o significado correto. Adaptadores permitem mudar o tipo de um objeto através de um filtro e são usados para acoplar classes que, de outra forma, seriam incompatíveis quanto a tipos. Extensão de classe permite adicionar métodos e variáveis de instancia a classes sem a necessidade de edição do código fonte destas. Shell dinâmico e extensão dinâmica possuem algumas das características de meta-objetos e meta-classes, respectivamente. Eles formam um modelo reflexivo estaticamente tipado. Shell dinâmico permite redirecionar todas as mensagens enviadas a um objeto e extensão dinâmica permite substituir métodos de uma classe em tempo de execução. Todas as construções são originais, podem ser adicionadas em uma linguagem estaticamente tipada sem danificar o sistema de tipos e resolvem alguns problemas descritos na literatura de orientação a objetos. / This thesis proposes five constructions for object-oriented languages. Some of them can be implemented using a preprocessor. These constructions are: class view, adapter, class extension, dynamic shell, and dynamic extension. All of them are based in the concept of filter, that is an object that intercepts the messages sent to another object. Class view allows correcting misinterpretations about the semantics of a class in code of other classes. A filter is used to translate the messages to the correct semantics. Adapters allow changing the type of an object through a filter and are used to glue type incompatible classes. Class extension allows adding methods and instance variables to classes without editing the source code of these classes. Dynamic Shell and dynamic extension have some of the characteristics of meta-objects and meta-classes, respectively. They compose a statically typed reflective model. Dynamic shell allows to redirect all messages sent to an object and dynamic extension allows replacing methods of a class at run time. All constructs are original and can be added to a statically typed language. They solve some problems described in the object-oriented literature.
