This paper introduces Repage, a computational system that adopts a cognitive theory of reputation. We propose a fundamental difference between image and reputation, which suggests a way out from the paradox of sociality, i.e. the trade-off between agents' autonomy and their need to adapt to social environment. On one hand, agents are autonomous if they(More)
In this paper we will present the EMIL project, " EMergence In the Loop: Simulating the two-way dynamics of norm innovation " , a three-year project funded by the European Commission (Sixth Framework Programme-Information Society and Technologies) in the framework of the initiative " Simulating Emergent Properties in Complex Systems ". The EMIL project(More)
In this paper the notion of emergence in complex social systems is rediscussed as a necessary instrument for a theory of the macro-micro link. Referring to Schelling's model of segregation, emergent effects are defined as effects generated by (inter)acting micro-social entities, and implemented upon, but not incorporated into, their rules. In the successive(More)
In this paper we have compared two independent models implemented to analyze the eects of social information transmission. The rst of them, Repage, is centered on an articulated theory of social evaluations. The second system, that has been developed in NetLogo, follows the same specications of the Repage model but with several simplications. We implemented(More)
One of the cognitive processes responsible for social propagation is social learning, broadly meant as the process by means of which agents' acquisition of new information is caused or favoured by their being exposed to one another in a common environment. Social learning results from one or other of a number of social phenomena, the most important of which(More)
