Patients in token-economy programs are generally unable to reinforce each other's behavior with tokens and social interaction among patients is usually minimal. In this study, all patients on a token economy ward of a state hospital were given a daily allowance of special transferable tokens in addition to whatever other tokens they earned. Transferable tokens could be spent by any patient except the one to whom they were issued. Both the frequency of social interaction and the number of different patients interacted with increased significantly.
