Abstract The paper examines the formation of color categories and color terms in a pop­ ulation of autonomous individuals, i.e. simulated agents. Each agent is modeled to perceive color stimuli, to categorize the stimuli and to lexicalize the categories in or­ der to communicate with other agents in the population. During these interactions the agents adapt their internal representations to be more successful in future interac­ tions. The categorization of the color perception is individualistic and influenced only by the nature of the agents' perception and its environment. The color categories can be associated with word forms with which the agents communicate color meanings. The pressure to successfully convey color meaning gives rise not only to coherent color lexicons, but also to a coherent categorization of color perception. The results add to the view that certain aspects of language behave as complex dynamic systems, benefiting from self­organization and cultural interactions.
1 Introduction Human color perception and related cognitive processes have been extensively studied and have been the topic of many discussions in philosophy, psychology, anthropology and linguistics. Although the focus has always been on descriptive analysis of color cognition, this paper investigates aspects of color using experiments done in artificial and well­controlled experiments to simulate color categorization and color naming in a population of agents. Results are given, and some speculation is offered on how the results can shed new light on old discussions. Color perception can be studied at different levels. At the physical level, electro­ magnetic energy is converted in the photoreceptors of the retina into neural signals that are then conveyed to the brain. Humans have three types of ...
