Relatedness decreases and reciprocity increases cooperation in Norway rats.
Kin selection and reciprocity are two mechanisms underlying the evolution of cooperation, but the relative importance of kinship and reciprocity for decisions to cooperate are yet unclear for most cases of cooperation. Here, we experimentally tested the relative importance of relatedness and received cooperation for decisions to help a conspecific in wild-type Norway rats (Rattus norvegicus). T...
متن کاملCooperation in social dilemmas, trust and reciprocity
The present study attempts to connect cooperative behavior in the repeated play prisoner’s dilemma (RPPD) with ‘‘trusting’’ and ‘‘reciprocal’’ behavior. Our goal is to see if people with different propensities to cooperate exhibit differing degrees of trust and reciprocity. We find the subjects who choose to cooperate in a RPPD game exhibit higher levels of trust. However when it comes to recip...
متن کاملCooperation under Indirect Reciprocity and Imitative Trust
Indirect reciprocity, a key concept in behavioral experiments and evolutionary game theory, provides a mechanism that allows reciprocal altruism to emerge in a population of self-regarding individuals even when repeated interactions between pairs of actors are unlikely. Recent empirical evidence show that humans typically follow complex assessment strategies involving both reciprocity and socia...
متن کاملGeneralized Reciprocity in Rats
The evolution of cooperation among nonrelatives has been explained by direct, indirect, and strong reciprocity. Animals should base the decision to help others on expected future help, which they may judge from past behavior of their partner. Although many examples of cooperative behavior exist in nature where reciprocity may be involved, experimental evidence for strategies predicted by direct...
متن کاملPathways to social evolution: reciprocity, relatedness, and synergy.
Many organisms live in populations structured by space and by class, exhibit plastic responses to their social partners, and are subject to nonadditive ecological and fitness effects. Social evolution theory has long recognized that all of these factors can lead to different selection pressures but has only recently attempted to synthesize how these factors interact. Using models for both discr...
