The law of less work (Hull, 1943) is our natural tendency given two alternatives with equal incentives to pick the less demanding one. This notion also appears in the field of judgment and decision making (Gigerenzer & Goldstein, 1996; Tversky & Kahneman, 1974), it is referred to as internal cost of effort. Cognitive parsimony is our tendency to favour low-effort strategies that help us to decide faster and simple strategies to approach a complex problem. An experimental paradigm for this phenomenon has been developed by Kool, McGuire, Rosen, & Botvinick (2010) and referred to as the demand selection task. In …

Individuals playing a sequence of different games have shown to learn about the other player’s behavior during their initial interaction and apply this knowledge when playing another game with the same individual in the future. Here we use a published computational cognitive model to generate predictions for an upcoming human study. The model plays both Prisoner’s Dilemma and Chicken Game with a confederate agent who uses one of two predetermined strategies and whose level of trustworthiness is manipulated. We go beyond the standard postdictive practice and adopt the increasingly popular practice of using the model to make a priori predictions …

The Intergroup Prisoner’s Dilemma with Intragroup Power Dynamics (IPD^2) is a new game paradigm for studying human behavior in conflict situations. IPD^2 adds the concept of intragroup power to an intergroup version of the standard Repeated Prisoner’s Dilemma game. We conducted a laboratory study in which individual human participants played the game against computer strategies of various complexities. The results show that participants tend to cooperate more when they have greater power status within their groups. IPD^2 yields increasing levels of mutual cooperation and decreasing levels of mutual defection, in contrast to a variant of Intergroup Prisoner’s Dilemma without intragroup …
