Resumo
Five pigeons served as subjects in an experiment that examined the effects of variable as opposed to fixed delays on preference in a self‐control paradigm (choice between larger, more delayed and smaller, less delayed reinforcers). Nonindependent concurrent variable‐interval schedules were used to measure choice. When delays to the larger, more delayed reinforcers were variable as opposed to fixed, the subjects showed an increased preference for that alternative (the self‐control alternative). A series of regressions revealed that the hyperbolic decay model and incentive theory provided poor fits to the data, but a modified version of the generalized matching law provided an adequate fit. Together, consistent with a general prediction made by discounting models, the data supported the conclusion that variable delays can increase self‐control. However, specific discounting models were not able to explain the present data well.
