....of its current sensory input [59] It gets reinforced (reinforcement learning[58] increase of statistic bias for the sensor[59] on the validity of its choice. The embodied aspect of grounding of meaning has also been neglected by simulated studies of language evolution (e.g. 60] 61] 62] [63], 64] In these works, grounding of communication is regarded as a computational problem that can be solved solely by means of combinatorial analysis. For these authors, categorization of sensor perceptions into concepts results from a process of statistical elimination among all possible ....

....inclusive fitness considerations and costs due to exploitation of the signal by predators, etc. then predicting the evolution of the communication system is trivial. Reliable communication requires, on average, honest signallers and trusting receivers, and thus will only develop when PS 1 As Di Paolo (1997) has pointed out, both Ackley and Littman (1994) and Oliphant (1996) do not formally demonstrate that kin selection has affected the course of evolution in their models. They simply assume that kin selection can be equated with spatial arrangement, in which an agent interacts with neighbours who ....

....it must be modelled as a game of imperfect information, in which the signaller knows something that the receiver does not. Some theorists might find this contentious: after all, Krebs and Dawkins (1984) have characterized animal communication as being more about persuasion than information, and Di Paolo (1997) has argued that the term communication should not be limited to situations of information exchange but defined more broadly as coordinated action. However, alarm and food calls clearly involve one animal with privileged access to an item of information about the world deciding whether or not ....

....change that occurs with increasing complexity and parallelism of a communication system: signals begin to lose their intrinsic meanings. The view of a context independent meaning of signals is going back to Shannon s information theory and was increasingly criticized in the past five years (e.g. DiPaolo, 1998). The new interpretation of communication is that the meaning of signals perceived by individual agents is evolving in the process of interaction between each agent s local vision and the global vision of the team, which is bigger then the sum of its parts. A simple illustration of this process ....

....a process of structural coupling with the medium. If the medium is also a structurally plastic system then both systems may become structurally interlocked, mutually selecting their plastic changes. More connections with the theory of autopoiesis and inter agent communication can be found in (DiPaolo, 1998). The autopoietic view of adaptation requires a departure from the idea that adaptation can be measured by observer independent scales and that evolution proceeds in accordance with those measures. The mutual adaptation of a system and its environment has been termed coevolution in Artificial ....

....the way how the agents might use their communication skills, but the experiments are not based on the learner s fitness advantage. The experiments do therefore complement studies on the evolution or learning of communication where fitness or task achievement usually play a central role ( MdRM96] Pao97] Nob98] 2. Learning in a social context. We investigate learning by teaching. In our experiments the learner using an imitative following strategy is literally guided by the teacher through the environment. This is more related to Vygotsky s arranging experiences ideas rather than didactic ....

.... here varies from other studies of the emergence of communication which have typically examined communication between symbolic agents over a symbolic channel (Steels, 1997a; Kirby, 1998b) or communication of a single concept with a single symbol, or set of symbols in parallel (Oliphant, 1998; Di Paolo, 1998; Cangelosi and Parisi, 1998; Oliphant and Batali, 1996) 1 An approach similar to ours has been taken by Batali (1998) who also used recurrent networks as communicative agents. However, whereas our concepts are represented as points within the unit hypercube (a continuous space) his concepts ....
