    • We trace the difference between the ways in which apes and humans co–operate to differences in communicative abilities, claiming that the pressure for future–directed co–operation was a major force behind the evolution of language. Competitive co–operation concerns goals that are present in the environment and have stable values. It relies on either signalling or joint attention. Future–directed co–operation concerns new goals that lack fixed values. It requires symbolic communication and context–independent representations of means and goals. We analyse these ways of co–operating in game–theoretic terms and submit that the co–operative strategy of games that involve shared representations of future goals may provide new equilibrium solutions.

  • Cooperation in apes and humans
  • 2003

  • Konferensbidrag (refereegranskat)abstract
    • Human consciousness serves many roles. It helps us imagine, dream, and think rationally. One capacity that human consciousness enables is cooperation. Here, we will focus on the interplay between cooperation and how subjects understand the minds of others. The aim is to compare and elucidate the similarities and differences between humans and apes as concerns cooperative behaviour. One difference can be described with the two terms ‘competitive cooperation’ and ‘collaborative cooperation’. Apes cooperate in competitive contexts, where the resource is available and accessible, but not yet in possession. Humans can as well cooperate in order to achieve something that is not manifest, but mainly desirable. Humans can imagine what is not there, and make their imaginations known to each other. Another difference is that apes cannot represent the goal without the means to reach them. Humans, on the contrary, can reflect about different ways of reaching the goal. Language gives human beings a great advantage in cooperative behaviour, especially in communication about goals and the way to reach them. Another aspect to the difference between humans and apes that concerns a more basic capacity than language-use is joint attention. It is necessary for cooperation for it to be possible for different subjects to attend to a common goal. Apes can engage in joint attention, but do not achieve the same complexity of joint attention as humans. For one thing, they can jointly attend only to things that are present in the context. This makes it difficult to cooperate in order to achieve a goal that is not present or implicated in the immediate environment. An application of our analysis of different kinds of cooperation is game theory. However, cooperative and non-cooperative games, considered in the traditional theory, are only the extremes of the possible levels of cooperation. By taking into account different levels of joint attention and communication, a more fine-grained analysis of different kinds of cooperation in game theory is possible.

  • Building rich and grounded robot world models from sensors and knowledge resources: A conceptual spaces approach
  • 2003
  • Ingår i: Proceedings of AMIRE 2003. - 1741070120 ; , s. 123-132
  • Konferensbidrag (refereegranskat)abstract
    • Robots interacting with other agents in rich information landscapes and complex dynamic physical environments require sophisticated and robust concept and knowledge management capabilities if they are to solve problems, communicate, learn and exhibit intelligent behaviours. In this paper we describe how conceptual spaces provide a powerful substrate upon which to build effective concept and knowledge management capabilities that integrate information from multiple sensory and symbolic sources. We use SONY AIBO robots and the robot soccer domain to illustrate our framework and approach. The conceptual spaces framework allows robots to build rich and grounded world models from a wide variety of internal and external knowledge resources, e.g. sensors, ontologies, databases, knowledge bases, the semantic Web, Web services, and other agents. Conceptual spaces provide an important and effective bridge between the perceptual level and the symbolic level by grounding sensory information to objects
