We study a spatial, one-shot prisoner’s dilemma (PD) model in which selection operates on both an organism’s behavioral strategy (cooperate or defect) and its decision of when to implement that strategy, which we depict as an organism’s choice of one point in time, out of a set of discrete time slots, at which to carry out its PD strategy. Results indicate selection for cooperators across various time slots and parameter settings, including parameter settings in which cooperation would not…

A comparative analysis of spatial Prisoner's Dilemma experiments: Conditional cooperation and payoff irrelevance

TLDR
A comparative analysis of data collected in three experiments on Prisoner's Dilemmas on lattices finds that the experiments do not provide significant evidence for non-innovative game dynamics such as imitate-the-best or pairwise comparison rules, whereas moody conditional cooperation is supported by the data from all three experiments.

Social Experiments in the Mesoscale: Humans Playing a Spatial Prisoner's Dilemma

TLDR
It is found that the cooperation level declines to an asymptotic state with low but nonzero cooperation, and an agent-based model based on the coexistence of these different strategies that is in good agreement with all the experimental observations is proposed.

Spatial games and the maintenance of cooperation.

TLDR
It is shown here that the essential results remain valid in more realistic situations where the spatial distributions of cells are random in two or three dimensions, and where winning is partly probabilistic (rather than being determined by the largest local total).

Cooperation and assortativity with dynamic partner updating

The natural tendency for humans to make and break relationships is thought to facilitate the emergence of cooperation. In particular, allowing conditional cooperators to choose with whom they

Human behavior in Prisoner's Dilemma experiments suppresses network reciprocity

TLDR
It is shown that when human subjects interact in a heterogeneous mix including cooperator, defectors and moody conditional cooperators, the structure of the population does not promote or inhibit cooperation with respect to a well mixed population.

Short-Range Mobility and the Evolution of Cooperation: An Experimental Study

TLDR
This work has carried out experiments on diluted grids with human subjects playing a Prisoner’s Dilemma and found no noticeable effect of mobility in space on the level of cooperation.

Consistent Strategy Updating in Spatial and Non-Spatial Behavioral Experiments Does Not Promote Cooperation in Social Networks

TLDR
The data of an experiment in which a total of 400 players play a Prisoner's Dilemma on a square lattice in two treatments is analyzed and the strategy updates are distinct from the most popular models which lead to the promotion of cooperation as shown by computer simulations of the strategy updating.

Heterogeneous networks do not promote cooperation when humans play a Prisoner’s Dilemma

TLDR
The largest experiments to date with humans playing a spatial Prisoner’s Dilemma on a lattice and a scale-free network suggest that population structure has little relevance as a cooperation promoter or inhibitor among humans.

Evolutionary games and spatial chaos

MUCH attention has been given to the Prisoners' Dilemma as a metaphor for the problems surrounding the evolution of coopera-tive behaviour1–6. This work has dealt with the relative merits of various
