About MICRAC

'MICRAC' is the acronym of « Modèles Informatiques et Cognitifs du Raisonnement Causal ». It is a 3.5 year project (December 2005 - June 2009) supported by the « Programme Blanc » of the French Agence Nationale pour la Recherche (ANR, http://www.agence-nationale-recherche.fr/).

The MICRAC project brings together four partners, the « Centre de Recherche en Informatique de Lens » (CRIL), the « Institut de Recherche en Informatique de Toulouse » (IRIT), the « Laboratoire d'Informatique de Paris-Nord » (LIPN), and the Laboratory "Cognition, Langues, Langage, Ergonomie" of Toulouse-Le Mirail (CLLE-LTC), around the problem of the identification of causal relations in a sequence of reported events. This problem differs from other traditional questions related to the idea of causality, such as the diagnosis of observed effects, or the qualitative simulation of dynamic systems.

    The goals of the MICRAC project are to develop:
  1. formal investigations of models of causal judgment.
  2. experimental investigations of these models.
  3. studies of the problems raised by their implementation.
  4. and more generally, to contribute a comparative study of these models.

About the Workshop

This workshop is organized at the occasion of the end of the MICRAC project. It will take place at IRIT (Université Paul Sabatier, Toulouse) on June 8-10, 2009.

The program will include:

    - 4 invited talks by:
  • Dr. Jacques Dubucs, Directeur de recherches CNRS, Institut d'Histoire et de Philosophie des Sciences et des Techniques, Paris
  • Dr. York Hagmayer, Georg Elias Müller Institut für Psychologie Universität Göttingen, Göttingen
  • Prof. Joseph Y. Halpern, Computer Science Department, Cornell University, Ithaca, NY
  • Dr. David Lagnado, Department of Cognitive, Perceptual and Brain Sciences, University College London, London

  • - presentations of the main MICRAC results by the partners.
    - solicited talks by researchers interested in causality modeling, coming from different disciplines.

An informal booklet distributed during the workshop will gather the extended abstracts (2-4 pages) of the presentations. All presentations will be in English. Reduced subscription fees may be collected for covering the expenses of the booklet proceedings, the coffee breaks, the lunches and a workshop dinner. The workshop will be open to all persons interested in attending.

The workshop is in part supported by the Maison des Sciences de l'Homme Toulouse, Université de Toulouse-Le Mirail.

  • "The use of causal networks in evidential reasoning"
    In everyday life, as well as more specialized contexts such as legal or medical decision making, people must make judgments based on complex bodies of interrelated evidence. What psychological processes do they use, and how do these relate to formal methods of evidence evaluation? One key factor seems to be people's ability to organize information into causal networks. This talk discusses two empirical studies that support this claim. Study 1 investigates the subtleties of alibi evidence, and suggests that people draw inferences based on network representations of the evidence. Study 2 looks at the selection of new information, and shows that people are sensitive to the differential diagnosticity of evidence within a causal network.
