Samenvatting

The question how humans acquire perceptual categories is far from being resolved. Specifically the balance between nature and nurture remains the topic of heated debate. We present a computational model and take as case study colour categories to study two issues in perceptual category acquistion.
The first issue is the effect of linguistic communication on categories during their acquisition: we demonstrate how categories can become coordinated under the influence of language. The second issue concerns the amount of coordination needed between the categories of individuals in order to achieve unambiguous communication. We show that, depending on how strictly linguistic utterances are interpreted, coordination of the individuals' categories is not always a prerequisite for successful communication.
In order to investigate the influence of language on category acquisition, we have constructed two models. In the first, language has a direct influence on the category formation: both categories and their forms are learned in one stage; in the second model learning is divided in two stages: in the first stage the agents induce their categories individually from the environment and in the scond stage they learn the forms for communicating about these categories without further changing their category repertoires.
