Conference Proceedings

The official proceedings appeared end of 1999 under the title "Understanding Representation in the Cognitive Sciences" with Kluwer Academic / Plenum Publishers, New York.



Purpose and Topics

The goal of this single-track conference was to investigate and discuss new approaches and movements in cognitive science in a workshop-like atmosphere. Among the topics which seem to have emerged in the last years are: embodiment of knowledge, system theoretic and computational neuroscience approaches to cognition, dynamics in recurrent neural architectures, evolutionary and artificial life approaches to cognition, and (epistemological) implications for perception and representation, constructivist concepts and the problem of knowledge representation, autopoiesis, implications for epistemology and philosophy (of science).

    Evidence for a failure of the traditional understanding of neural representation converges from several fields. Neuroscientific results in the last decade have shown that single cell representations with hierarchical processing towards representing units seems not the way the cortex represents environmental entities. Instead, distributed cell ensemble coding has become a popular concept for representation, both in computational and in empirical neuroscience. However, new problems arise from the new concepts. The problem of binding the distributed parts into a uniform percept can be "solved" by introducing synchronization of the member neurons. A deeper (epistemological) problem, however, is created by recurrent architectures within ensembles generating an internal dynamics in the network. The cortical response to an environmental stimulus is no longer dominated by stimulus properties themselves, but to a considerable degree by the internal state of the network. Thus, a clear and stable reference between a representational state (e.g. in a neuron, a Hebbian ensemble, an activation state, etc.) and the environmental state becomes questionable. Already learned experiences and expectancies might have an impact on the neural activity which is as strong as the stimulus itself. Since these internally stored experiences are constantly changing, the notion of (fixed) representations is challenged. At this point, system theory and constructivism, both investigating the interaction between environment and organism at an abstract level, come into the scene and turn out to provide helpful epistemological concepts. The goal of this conference is to discuss these phenomena and their implications for the understanding of representation, semantics, language, cognitive science, and artificial life.

    Contrary to many conferences in this field, the focus is on interdisciplinary cooperation and on conceptual and epistemological questions, rather than on technical details. We are trying to achieve this by giving more room to discussion and interaction between the participants (e.g., invited comments on papers, distribution of papers to the participants before the conference, etc.). According to the interdisciplinary character of cognitive science, we welcome papers/talks from the fields of artificial life, empirical, cognitive, and computational neuroscience, philosophy (of science), epistemology, anthropology, computer science, psychology, and linguistics.

    The conference is centered around but not restricted to the following topics:

  1. Representation - epistemological concepts and findings from (computational) neuroscience, cognitive science (recurrent neural architectures, top-down processing, etc.), and philosophy;
  2. Alternatives to representation - applying constructivism to cognitive systems;
  3. Modeling language, communication, and semantics as a dynamical, evolutionary and/or adaptive process;
  4. Representation and cognition in artificial life;
  5. What is the role of simulation in understanding cognition?

Notes:

Plenary Discussion

The focus of a plenary discussion was not be on details, but rather on conceptual, interdisciplinary and integrative issues!

Interlude & Postlude

The purpose of interlude and postlude (Thursday morning and Friday evening) was to sum up, discuss, and integrate the trends of the talks in a larger picture and to develop some kind of vision for cognitive science. The focus was on the questions below and "fruitful" interdisciplinary interaction.

Conference Site

SCHLOSS NEUWADEGG The conference took place in a small beautiful baroque castle, Schloss Neuwaldegg, in the suburbs of Vienna.

It is surrounded by a beautiful forest and a good (international and Viennese gastronomic) infrastructure. On the tram it takes only 20 minutes to the center of Vienna.
