Communication richness failed to produce significant differences in first-mover investments. However, the topics of conversation made a significant difference: the amounts sent were considerably higher in the unrestricted communication conditions than in the restricted communication and no-communication conditions. Most importantly, we find that first-movers’ expectations of second-movers’ reciprocation are influenced by communication and strongly predict their levels of investment.The final publication is available at Springer via http://dx.doi.org/10.1007/s11229-009-9487-ytrustlaboratory experimentscommunicationsocial normscooperationcomputer-mediated communicationCommunicationExperimental Analysis of BehaviorMetaphysicsPhilosophy of LanguageThe Medium or the Message?
