Abstract This paper explores the hypothesis that language communication in its very first stage is bootstrapped in a social learning process under the strong influence of culture. A concrete framework for social learning has been de­ veloped based on the notion of a language game. Autonomous robots have been programmed to behave according to this framework. We show ex­ periments that demonstrate why there has to be a causal role of language on category acquisition; partly by showing that it leads effectively to the bootstrapping of communication and partly by showing that other forms of learning do not generate categories usable in communication or make infor­ mation assumptions which cannot be satisfied.
1 Introduction How children acquire the meaning of words is a fascinating, still unresolved prob­ lem but a key towards understanding how human­level language communication could ever have developed. This paper addresses two basic puzzles concerning this process: 1. How does the bootstrapping into communication take place? What are nec­ essary prerequisites to enable the magic moment when the child learns `how to mean' [Halliday, 1987]? 1  2. How is meaning acquired? The meanings used by a speaker cannot directly be observed by the listener, so how can a listener who does not know the meaning of words ever learn them? There are two main lines of thinking on these questions: individualistic learn­ ing and social learning. In the case of individualistic learning, the child is assumed to receive as input a large number of example cases where speech is paired with specific situations. She is either already mastering the necessary concepts or able to extract through an inductive learning process what is essential and recurrent of these situations, in ...
