Esta dissertação aborda a educação digital dentro da contemporaneidade, tendo como base dois pontos de articulação essenciais: a cibernética pedagógica e a era das redes. Traça portanto um panorama das relações pertinentes a cada um dos tópicos, fundamentando questões conceituais de relevância para o entendimento da complexidade do assunto apresentado. Para tal elenca tópicos que caracterizam as dimensões essenciais de mudanças paradigmáticas, como a sociedade na era das redes, a educação digital na era das redes, a evolução dos suportes tecnológicos com implicações paradigmáticas no campo educacional e megatendências evolutivas do conhecimento em rede. Acrescenta ainda um estudo de caso consubstanciando a validade dos tópicos apresentados do ponto de vista conceitual e prático. O trabalho desenvolve-se com base principalmente nas leituras de literatura especializada, e no registro de diversas fontes documentacionais complementares que atestam a multidimensionalidade informacional em um mundo povoado por redes de comunicação e informação. Cada fonte ao seu modo contribuiu para tecido conceitual do trabalho. A Internet foi fonte fundamental para tratar certas questões de ponta no campo da educação digital. / This dissertation presents the digital education within the contemporary times. The basis of this work comprises of two essential viewpoints: the pedagogical cybernetics and the age of networks. It also points out a panorama of the relations belonging to each topic, by establishing several relevant conceptual issues for the understanding of complexity about the topics. The study selects several topics in order to distinguish the essential dimensions in the paradigmatic changes, such as the society in the age of networks, the digital education in the age of networks, the evolution of technological instruments by considering paradigmatic implications in the educational field, and developing megatendencies of knowledge network. It still adds a case study for validating the presented topics under a conceptual and practical perspective. The discussion was based mostly in the reading of specialists literature, and in the selecting of several complementary documentation sources, which testifies the informational multidimensionality in a world of intense communication and information networks. Every source in its peculiar way provided resources for the conceptual tissue of the study. Internet was also a very fundamental source for treating some very advanced issues according to the digital education field.

Os processos de produção de arte eletrônica contemporânea (pós-anos 1990) são discutidos sob a ótica da cibernética de segunda ordem, cujos princípios consideram o observador durante a observação dos sistemas, analisando como circular a relação entre observador e observado. A metodologia empregada baseia-se na Teoria Fundamentada nos Dados, cujo argumento emerge do entrecruzamento do arcabouço teórico sobre o assunto com as informações coletadas através de observações, conversas e entrevistas. A análise se desenvolve em três capítulos, todos atravessados pela exploração das relações entre acidente e controle no campo da arte eletrônica. No primeiro capítulo levamos em consideração os aspectos conceituais e estruturais da produção artística em questão. No segundo, exploramos as relações que se tecem entre agentes criativos durante o processo, observando tal produção enquanto sistema social pautado em conversações. No terceiro, vislumbramos a experiência criativa coletiva enquanto possibilidade de construção de espaços de conhecimento, e arriscamos uma auto-crítica sobre o que apreendemos sobre o processo de produção da arte eletrônica. Nossas considerações finais trazem nossa apreensão para as relações entre a arte eletrônica e a arquitetura, apontado para o caráter utópico de nossos argumentos. / The production processes on contemporary media art (post-1990\'s) are discussed through the second order cybernetics perspective, whose principles study the observer and observed as a circular motion. The research methodology is based on the Grounded Theory. The argument emerges by blending together the theoretical framework on the subject with the information collected through observations, conversations and interviews. The analysis is developed in three chapters, all interrelated exploring the relationships between accident and control in the media art field. In the first chapter the conceptual structure of this artistic production is analyzed. In the second chapter, we explore the relationships that emerge between creative agents during the process, observing such production as a social system being ruled by conversation. In the third chapter, picturing the collective creative experience as means to the construction of knowledge spaces, we apply to the architectural field what we learned about the production process of media art. Our final conclusions bring our perception to the relations between media art and architecture leading to the utopian character of our arguments.

To increase fitness for survival, organisms not only passively react to environmental changes but also actively predict future events to prepare for potential hazards within their environment. Accumulating evidence indicates that the human brain is a remarkable predictive machine which constantly models causal relationships and predicts future events. This ‘predictive processing' framework, a prediction-based form of Bayesian inference, states that the brain continuously generates and updates predictions about incoming sensory signals. This framework has been showing notable explanatory power in understanding the mechanisms behind both human behaviour and neurophysiological data and elegantly specifies the underlying computational principles of the neural system. However, even though predictive processing has the potential to provide a unified theory of the brain (Karl Friston, 2010), we still have a limited understanding about fundamental aspects of this model, such as how it deals with different types of information, learns statistical regularities and perhaps most fundamentally of all what its relationship to conscious experience is. This thesis aims to investigate the major gaps in our current understanding of the predictive processing framework via a series of studies. Study 1 investigated the fundamental relationship between unconscious statistical inference reflected by predictive processing and conscious access. It demonstrated that predictions that are in line with sensory evidence accelerate conscious access. Study 2 investigated how low level information within the sensory hierarchy is dealt with by predictive processing and regularity learning mechanisms through “perceptual echo” in which the cross-correlation between a sequence of randomly fluctuating luminance values and occipital electrophysiological (EEG) signals exhibits a long-lasting periodic (~100ms cycle) reverberation of the input stimulus. This study identified a new form of regularity learning and the results demonstrate that the perceptual echo may reflect an iterative learning process, governed by predictive processing. Study 3 investigated how supra-modal predictive processing is capable of learning regularities of temporal duration and also temporal predictions about future events. This study revealed a supramodal temporal prediction mechanism which processes auditory and visual temporal information and integrates information from the duration and rhythmic structures of events. Together these studies provide a global picture of predictive processing and regularity learning across differing types of predictive information.

Cette thèse analyse les incidences des avancées d’une rationalité technoscientifique sur les définitions classiques de l’humain. Elle discerne, dans sa présentation de ce phénomène, le lien entre la technoscience, la cybernétique et le posthumanisme qui en découle. Elle souligne les mutations et projets de remodèlement de l’humain qui traversent cette rationalité technoscientifique et son paradigme informationnel cybernéticien. Cette rationalité technoscientifique, polémique aux ontologies dites conservatrices, soutenant une vision amorale de la RDTS (Recherche & Développement technoscientifique), accouche d’un posthumanisme – en rapport difficile avec le corps – qui bouscule les définitions classiques de l’humain judéo-chrétien, dont l’anthropologie théologique évangélique. Traitant, dans une première grande section de trois chapitres, de la rationalité technoscientifique et de ses visions de l’humain, la thèse permet la mise en exergue des enjeux principaux se dégageant des nouveaux questionnements des anthropologies classiques soumises aux pressions de la RDTS. Dans la deuxième partie, encore de trois chapitres, qui porte sur l’anthropologie évangélique, la thèse situe les Évangéliques historiquement et doctrinalement, pour mieux relever les éléments identitaires du mouvement et les grandes déterminations théologiques à l’intérieur desquels se déploie cette anthropologie. La présentation de cette dernière se décline à partir des différentes compréhensions du motif anthropologique évangélique par excellence, l’imago Dei et le concept de l’unicité de l’humain dont les fondements semblent de plus en plus fragiles à la lumière des conclusions des recherches en paléontologie et en cognition animale. Si plusieurs défis importants sont posés à l’anthropologie évangélique, la thèse, se limitant à une critique évangélique de la rationalité technoscientifique et des réponses évangéliques à cette dernière, analyse une question essentielle pour la pensée évangélique, celle de l’humain homo ii faber et l’anthropotechnie, versus le remodèlement de l’humain autour des interrogations posthumanistes sur le corps et la question du salut. Cette thèse apporte une contribution 1) sur le plan de la synthèse qu’elle présente de l’anthropologie évangélique, 2) de la compréhension de l’identité évangélique, sa singularité et sa diversité, et 3) des manières dont une théologie évangélique peut entrer en dialogue avec la raison technoscientifique. Elle lève le voile sur l’utilisation tous azimuts du concept de l’imago Dei et de son insuffisance, à lui seul, pour apprécier les véritables enjeux du débat avec la rationalité technoscientique. Elle insinue que ce motif doit être analysé en conjonction avec la christologie dans l’approfondissement du Logos incarné, pour en mieux apprécier l'étendue. Ce n'est que dans ce lien qu’ont pu être trouvés des éléments capables d'articuler ce qui est en germe dans l'imago Dei et suggérer une définition de l’humain capable de prendre en considération les défis d’une rationalité technoscientifique et de son posthumanisme. / This thesis analyzes the impact of proposals by a technoscientific rationality (or RDTS) on the classical definitions of what is human. It discerns in its presentation of the phenomenon the link between technoscience, cybernetics and post-humanism which has developed from them. Then there are the mutations and projects to remodel humans which arise with RDTS and its cybernetic informational paradigm. Technoscience, with its polemics against any ontology considered conservative, supports an amoral vision of RDTS and produces a posthumanism with its difficult relation to the human body. It also disrupts classical Judaeo-Christian definitions of what is human, among which we find evangelical theological anthropology. This thesis is divided into two sections of three chapters each. The first section examines RDTS and its vision of what is human. The principal issues which recent questioning of classical anthropology has produced, arising from the pressure of RDTS developments, are examined. Then the second section of three chapters will present evangelical anthropology, beginning with the historical and doctrinal context of evangelicalism. The elements of evangelical identity are explained along with the primary theological concepts which surround this anthropology. A variety of evangelical positions will be presented, related to the imago Dei and the concept of unicity of the human. While this concept is crucial for evangelicals, it is highly contested by recent research in paleontology and animal cognition. After examining the important new challenges facing evangelical anthropology, this thesis will concentrate on existing evangelical critiques of RDTS and posthumanism and iv refining them. Then an essential question for evangelicals will be examined: the homo faber and anthropotechnie versus the remodelling of the human involved in posthumanist questioning of the body and of salvation. Three contributions emerge from this thesis: 1) a synthesis of evangelical anthropology, 2) an understanding of evangelical identity in its distinctiveness and in its diversity and 3) an identification of necessary factors for evangelical theology to employ in a dialogue with RDTS. The difficulty of using the imago Dei in all direction is demonstrated along with a denial that this concept alone can address all the serious issues RDTS raises. Rather this motif needs to be combined with Christology and particularly the incarnation of the Logos to widen the treatment of the subject. It is only with that link that necessary elements contained in the imago Dei can be articulated and a definition for the human can be made which can address the challenges of RDTS and its posthumanism.
