The Project

This website is the result of a cooperation between the Institute of Psychology at the University Gießen and the Center of Cognitive Science at the University Freiburg.

Our main interest was the visualization of the theory of preferred mental models in spatial reasoning. The site collects the emprirical data of various experiments which were run during the last years and simulates the data according to the predictions of the mental model theory. The user can compare the empirical complexity of each task with the evaluation of the mental model theory. This comparison makes it possible to seperte between subsets of tasks whose empirical complexity is higly covered by the prediction of the mental model theory from those who still lack of good explanations by the current assumptions.

The project was implemented during May 2013 and December 2013. Further theoretical results can be read in the following publications.
