The origins and coordination of color categories is one of the main topics I have investigated. In my experiments the agents had to agree both on the perceptual categories they use to divide the complete spectrum of colors and on the words they use for expressing these categories. These experiments have shown that language is capable of coordinating the location of the perceptual categories. You can find a movie in which you can see the evolution of the colour categories in an artificial population here (20MB mpg).

Another idea that we are pursuing is the idea of cognitive semantics. This is an old idea which states that the meaning of a sentence is a progam the speaker wants the hearer to interpret. I have used the Incremental Recruitment Language (IRL) framework to generate these kind of programs which are then uttered in a grammatical language using Fluid Construction Grammar (FCG). I have been looking into the problem of expressing these semantic programs in language and parsing a grammatical utterance into such a program and how such mappings between programs and language can get conventionalised in a population of agents.
