Talk: Prof. Maurice Grinberg (New Bulgarian University)

May 23th

MEi:CogSci together with the CEEPUS network "Cognitive Science, Knowledge Studies, and Knowledge Technologies" and the Vienna Cognitive Science Hub are happy to invite you to the following talk and workshop by

Prof. Maurice Grinberg (New Bulgarian University)
Talk: Can Social Relations Influence Cooperation in Prisoner’s Dilemma?
Date: May 23th, 2023, 11:30 - 13:00
Location: Lecture hall HS 3C (University of Vienna, Universitätsstr. 7 (NIG), 3rd floor)


Abstract: 
The seminar will discuss the impact of social role assignment and the corresponding payoff distribution on cooperation in the Prisoner’s dilemma following the types of relations according to Fiske’s relational models’ theory: communal sharing, authority ranking, equality matching, and market pricing. The corresponding roles and payoff distribution are teammates (each player receives the sum of the payoffs), partners (each player receives half of the sum of the payoffs), boss and subordinate (the boss receives 2/3 and the subordinate 1/3 of the sum of the payoffs), and opponents (each player receives the standard payoff). The results show that in the teammates’ and partners’ conditions cooperation was significantly higher than in the other conditions. Surprisingly, the results for the boss and subordinate condition although sharing a similar payoff distribution rule to the teammates’ and partners’ conditions were more similar to the opponents’ condition with significantly lower cooperation rate.

 

 

Workshop: Context effects on cooperation in the Prisoner's dilemma
Date: May 25th, 2023, 9:00 - 13:00 Location: Lecture hall HS 2i (University of Vienna, Universitätsstr. 7 (NIG), 2nd floor)

Abstract:
The Prisoner's dilemma game is considered a good framework to study cooperation in a wide range of social situations. The game is a social dilemma in the sense that the individualistic behaviour can lead to the highest payoff of the game at the expense of the other opponent if she cooperates. On the other hand, if both players behave individualistically the payoffs they are getting are lower than if they both cooperated. The latter however is related to the risk that one of the players unilaterally will become individualistic tempted by the highest payoff. Despite the complexity of the situation, behavioural experiments show that people cooperate quite often in Prisoner’s dilemma and the possible reasons for such a behaviour has attracted continuous interest and exploration. The workshop will present recent results along this line of research, related to the influence on cooperation of the payoff structure of the game, information acquisition, Simpson’s paradox effects, players role effects, etc.
