Abstract The paper proposes a mechanism for the spontaneous formation of perceptually grounded meanings under the selectionist pressure of a discrimination task. The mechanism is defined formally and the results of some simulation experiments are reported.
Keywords: origins of meanings, self­organization, distributed agents, open systems.
1 Introduction The research reported here is part of a larger research program to understand the origins of language and meaning using complex systems mechanisms such as self­organisation, co­evolution, and level formation [5]. This paper focuses on the meaning creation process. A theoretical model is proposed to explain how an autonomous agent may originate new meanings. The agent is au­ tonomous in the sense that its ontology is not explicitly put in by a designer, nor is there any explicit instruction. 1  For the purpose of this paper, meaning is defined as a conceptualisation or categorisation of reality which is relevant from the viewpoint of the agent. Meanings can be expressed through language, although they need not be. Meaning takes many forms depending on the context and nature of the situ­ ation concerned. Some meanings (such as colors) are perceptually grounded. Others (such as social hierarchies) are grounded in social relations. Still oth­ ers (such as goals or intentions for actions) are grounded in the behavioral interaction between the agent and the environment. This paper focuses on perceptually grounded meanings, although the proposed mechanism could also be used for other domains. The proposed model is theoretical in the sense that no claim is made or evidence given that it is empirically valid for humans or animals. The goal is only to outline and validate possibilities. ...
