We investigated the evolution of signal-meaning associations (symbols and words) when there is common interest as well as a conflict between communicating individuals. For more information, see the paper that we published on it.
Our article is based on an analysis of the spatial dynamics of different language users. In some cases we carried out explicit simulations, some of which can be viewed here.
The original of the painting by Breughel that forms the background of this page can be admired in the Kunsthistorisches Museum in Vienna.
