One consequence of stimulus sampling theory is the prediction of probability matching as the asymptotic response probability. That is, subjects tend to choose each alternative with the frequency of its reinforcement. This prediction has been tested in many experiments and the boundaries within which it holds have been delineated. However, the experiments which find probability matching have been criticized for doing one or more of several inappropriate things. It should be noted that probability matching is not a rational solution, in the sense that the behavior which maximizes gain would be always to choose the more frequently reinforced response. Some investigators have found it possible to devise experimental situations in which the subjects do come closer to maximizing behavior. This study attempts to differentiate the conditions which lead to matching behavior from those which lead to maximizing and to develop a mathematical model for this behavior. Author
