| Abstract: | Eight pigeons chose between pairs of different sizes and delays of reinforcement scheduled according to nonindependent concurrent variable-interval variable-interval schedules. The results were best described by the generalized matching law, where the relative effects of amount and delay on preference are independent and multiplicative. Order of presentation of the conditions had a significant effect on preference that was best represented in the model by a modification of the bias parameter. |
