Qualitative representations have proven to be useful formalisms for capturing human mental models. As a result, qualitative modeling could become an important tool for cognitive science. Specifically, an environment in which qualitative representations can be used to explore mental models and different type of reasoning and simulations can be performed on these models can be a useful tool for cognitive scientists. In this paper, we introduce the Qualitative Concept Map system, designed for cognitive scientists, for building and simulating qualitative and Bayesian models using qualitative process theory and Bayesian inference.
