Cooperative Behaviors

Cooperation in pairs of rats playing the prisoner's dilemma game was investigated. Six pairs of animals were taught to make either cooperative or uncooperative responses by running to one or the other end of a T-maze. Two T-mazes were joined together such that animals could respond simultaneously. Animals were run under conditions in which visual communication was present and absent. Mutually uncooperative responses were the most common and mutually cooperative behaviors the least preferred. Introduction of a barrier between the mazes, which removed visual communication between pairs, sharply accentuated uncooperative behavior. Similarities of the present findings to results with human subjects and the implications of using game theory for studying cooperative behavior in animals are discussed.

Iterated Prisoner’S Dilemma

Unlike traditional time series, the action sequences of human decision making usually involve many cognitive processes such as beliefs, desires, intentions and theory of mind, i.e. what others are thinking. This makes predicting human decision making challenging to be treated agnostically to the underlying psychological mechanisms. We propose to use a recurrent neural network architecture based on long short-term memory networks (LSTM) to predict the time series of the actions taken by the human subjects at each step of their decision making, the first application of such methods in this research domain. In this study, we collate the human data from 8 published literature of the Iterated Prisoner's Dilemma comprising 168,386 individual decisions and postprocess them into 8,257 behavioral trajectories of 9 actions each for both players. Similarly, we collate 617 trajectories of 95 actions from 10 different published studies of Iowa Gambling Task experiments with healthy human subjects. We train our prediction networks on the behavioral data from these published psychological experiments of human decision making, and demonstrate a clear advantage over the state-of-the-art methods in predicting human decision making trajectories in both single-agent scenarios such as the Iowa Gambling Task and multi-agent scenarios such as the Iterated Prisoner's Dilemma. In the prediction, we observe that the weights of the top performers tends to have a wider distribution, and a bigger bias in the LSTM networks, which suggests possible interpretations for the distribution of strategies adopted by each group.

Human Participants

Prisoner’s dilemma (PD) is one of the most popular concepts among scientific literature. The task is used in order to study different social interactions by giving participants the choice of defection or cooperation in a specific social setting/dilemma. This review concerns the technical characteristics of PD use in medical literature involving human subjects and how the different settings could influence the behaviours studied by the task. We identify all studies that have used PD in medical research with human participants and distinguish, following a heuristic approach, the seven parameters that can differentiate a PD task, namely a.Opponent parties’ composition; b.Opponent perceived type; c.Interaction flow; d.Number of rounds; e.Instructions, narration and options; f.Strategy and g.Reward matrix and payoffs. For each parameter, we highlight their variability as it is captured in the literature, and we describe how each one could influence the final outcome of the PD task. Our aim is to point out the heterogeneity of such methods in the past literature and to assist future researchers into methodology design.

Zusammenfassung: Der soziometrische Status und der Viktimisierungsstatus von 5. bis 11. Klässlern wurde ermittelt, der Status hypothetischer InteraktionspartnerInnen sowie deren angebliche Wahlen variiert, und die Reaktionen im Gefangenendilemma erfaßt. Die Reaktionen wurden sowohl durch die experimentell vorgegebenen als auch durch die erwarteten Wahlen der InteraktionspartnerInnen bestimmt: Kooperative Zuege wurden eher kooperativ, und kompetitive Zuege eher kompetitiv beantwortet. Darüber hinaus vermieden Mobbingopfer kompetitive Züge, während zwei Untergruppen der Abgelehnten gegensätzliche Strategiepräferenzen aufwiesen: Versuchspersonen, die sowohl Ablehnung als auch Mobbing erfahren («Viktimisiert-Abgelehnte») verhielten sich besonders kooperativ; abgelehnte ProbandInnen, die nicht viktimisiert werden («Nicht-viktimisiert-Abgelehnte») dagegen vergleichsweise kompetitiv. Die kooperativen Wahlen viktimisierter Versuchspersonen wurden nicht erwidert: Die Versuchspersonen reagierten gegenüber den Viktimisierten kompetitiver als sich die Viktimisierten ihrerseits gegenüber ihren InteraktionspartnerInnen verhielten. Diese Befunde bestätigen die Notwendigkeit, bei «Abgelehnten» zwei Untergruppen auf der Basis der Viktimisierungsdimension zu unterscheiden. Die Befunde werden ferner vor dem Hintergrund der Hypothese diskutiert, daß die Submissivität potentieller Opfer mit zu ihrer Viktimisierungs-Erfahrung beiträgt.

Moralistic Punishment

Abstract. The present study serves to test how positive and negative appearance-based expectations affect cooperation and punishment. Participants played a prisoner’s dilemma game with partners who either cooperated or defected. Then they were given a costly punishment option: They could spend money to decrease the payoffs of their partners. Aggregated over trials, participants spent more money for punishing the defection of likable-looking and smiling partners compared to punishing the defection of unlikable-looking and nonsmiling partners, but only because participants were more likely to cooperate with likable-looking and smiling partners, which provided the participants with more opportunities for moralistic punishment. When expressed as a conditional probability, moralistic punishment did not differ as a function of the partners’ facial likability. Smiling had no effect on the probability of moralistic punishment, but punishment was milder for smiling in comparison to nonsmiling partners.
