Human language is a unique ability. It sits apart from other systems of communication in two striking ways: it is syntactic, and it is learned. While most approaches to the evolution of language have focused on the evolution of syntax, this paper explores the computational issues that arise in shifting from a simple innate communication system to an equally simple one that is learned. Associative network learning within an observational learning paradigm is used to explore the computational difficulties involved in establishing and maintaining a simple learned communication system. Because Hebbian learning is found to be sufficient for this task, it is proposed that the basic computational demands of learning are unlikely to account for the rarity of even simple learned communication systems. Instead, it is the problem of observing that is likely to be central -- in particular the problem of determining what meaning a signal is intended to convey. 1 The learning barrier There is a lon...

... this paper demonstrates scaling up of this movement imitative strategy for transmitting a vocabulary across a group of robotic agents, i.e. from a teacher agent to several learner agents. In particular, it shows that imitative behaviour is necessary for the grounding of the agents' proprioceptions and speeds up the grounding of exteroceptions. These studies stress the importance of behavioural social mechanisms in addition to general cognitive abilities of associativity for grounding communication in embodied agents. In particular, it shows that a simple movement imitation strategy is an interesting scenario for the transmission of a language, as it is an easy means of getting the agents to share a common context of perceptions, which is a prerequisite for a common understanding of the language to develop. It is thus suggested that a behaviour -oriented approach might be more appropriate than a pure cognitivist one which is dominating in related studies of the mechanisms involved in grounding communication.

We address the issue of rational communicative behavior among autonomous self-interested agents that have to make decisions as to what to communicate, to whom, and how. Following decision theory, we postulate that a rational speaker should design a speech act so as to optimize the benefit it obtains as the result of the interaction. We quantify the gain in the quality of interaction in terms of the expected utility, and we present a framework that allows an agent to compute the expected utilities of various communicative actions. Our framework uses the Recursive Modeling Method as the specialized representation used for decision-making in a multi-agent environment. This representation includes information about the agent's state of knowledge, including the agent's preferences, abilities and beliefs about the world, as well as the beliefs the agent has about the other agents, the beliefs it has about the other agents' beliefs, and so on.

The emergence and evolution of human language has been the focus of increasing amounts of research activity in recent years. This increasing interest has been coincident with the increased use of computer simulation, particularly using one or more of the methods and techniques of ‘Artificial Life’, to investigate a wide range of evolutionary problems and questions. There is now a significant body of work that uses such computer simulations to investigate the evolution of language. In this thesis a broad review of work on the evolution of language is presented, showing that language evolution occurs as two distinct evolutionary processes. The ability to use language is clearly the result of biological evolution. But the changes that occur over time to all spoken languages can also be viewed as being part of a process of cultural evolution. In this thesis, work using artificial life models to investigate each of these processes is reviewed. A review of the methods and techniques used in artificial life is also presented early in the work. A novel model is developed which is used to explore the conditions necessary for the

We review some of the main theories about how language emerged. We suggest that including the study of the emergence of artificial languages, in simulation settings, allows us to ask a more general question, namely, what are the minimal initial conditions for the emergence of language? This is a very important question from a technological viewpoint, because it is very closely tied to questions of intelligence and autonomy. We identify anticipation as being a key underlying computational principle in the emergence of language. We suggest that this is in fact present implicitly in many of the theories in contention today. Focused simulations that address precise questions are necessary to isolate the roles of the minimal initial conditions for the emergence of language. 1 What is the problem of language emergence? It is very hard to imagine what life would be like without language. Before some point in our evolutionary history, however, our ancestors did not have language.

Introduction: the language gap Language is the main distinctive feature of our species. Why do we feel the urge to communicate with our fellows, and why is this form of communication, characterised by relevance, unique in animal kingdom ? In this chapter, we will first stress this specificity of human communication. In a second part, using computer evolutionary simulations, we will dismiss the usual claim that human communication is a specific form of reciprocal cooperation. A Darwinian account of language requires that we find a selective advantage in the communication act. We will propose, in the third part of this chapter, that such an advantage can be found if we consider language activity in the broader frame of human social organisation. In the continuation of the `chimpanzee politics' studied by de Waal (1982), the ability to form large coalitions must have been an essential feature of hominid societies (Dunbar 1996). We will suggest that relevant speech
