In this paper, we claim that agents confronting with new interactive situations apply behavioral heuristics that drastically reduce the problem complexity either by neglecting the other players’ incentives, or by restricting attention to subsets of “salient” outcomes. We postulate that these heuristics are sensitive to the manipulation of those features that can be modified without altering the (Nash) equilibrium structure of the game. We call these features “descriptive”. We test experimentally...

This paper revisited Gregory Bateson’s theory of hierarchical learning through an experiment testing the existence of context effect and learning spill-over in two following games: a coordination game and a two-step battle-of-the sexes. The first part of the experiment is seen as a kind of training period. The different treatments of the coordination game are, in fact, designed so to reinforce different representations of the games, requiring to look at different aspects of a series of images sh...

In this paper we test the effect of descriptive "features" on initial strategic behavior in normal form games, where "descriptive" are all those features that can be modified without altering the (Nash) equilibrium structure of a game. We observe that our experimental subjects behave according to some simple heuristics based on descriptive features, and that these heuristics are stable even across strategically different games. This suggests that a categorization of games based on features may b...

Game theory is a mathematical language for describing strategic interactions, in which each player's choice affects the payoff of other players (where players can be genes, people, companies, nation-states, etc.). The impact of game theory in psychology has been limited by the lack of cognitive mechanisms underlying game-theoretic predictions. ‘Behavioural game theory’ is a recent approach linking game theory to cognitive science by adding cognitive details about ‘social utility functions’, theo...

Coordination games have multiple Nash equilibria (i.e., sets of strategies which are best responses to one another). In weak-link coordination games players choose a number 1–7. Their payoff is increasing in the minimum number (or weakest link) and decreasing in the difference between their number and the minimum. Choosing 7 is an efficient equilibrium because it gives everybody a higher payoff than any other coordinated choice. Higher-payoff equilibria are riskier, however, so the game expresse...
