Abstract:
:Delay of reinforcement is generally thought to be inversely correlated with speed of acquisition. However, in the case of simultaneous discrimination learning, in which choice results in immediate reinforcement, delay of reinforcement can improve acquisition. For example, in the ephemeral reward task, animals are given a choice between two alternatives, A and B. Choice of A provides reinforcement, and the trial is over. Choice of B provides reinforcement and access to alternative A (thus, two reinforcements). Many animals appear unable to learn to choose B consistently, but inserting a 20-s delay between choice and outcome has been shown to facilitate optimal choice. Similarly, pigeons given a choice between a signal for one pellet and a signal for two pellets (each occurring without a delay) have difficulty learning to choose the two-pellet alternative, unless the reinforcement is delayed. In a version of object permanence, food is placed in one of two containers, and the pigeon must choose the container with the food. Pigeons have difficulty reliably choosing the correct container unless a brief delay is inserted between baiting and choice. Finally, pigeons have been shown to prefer a suboptimal alternative (a 20% chance of getting a cue for reinforcement) over an optimal alternative (a 100% chance of getting a cue for 50% reinforcement). However, if pigeons are forced to wait 20 s following their choice to receive the cues, no preference for the suboptimal alternative is found. Thus, impulsive choice may be reduced by delaying the consequence of that choice.
