The Contingency-Discriminability model of choice has generally used a constant (p or m) to describe confusion between response location and reinforcers when location is unchanging, and the same approach has usually been taken in the development in models that combine control of elapsed time and reinforcer location. The value of m is the probability that a reinforcer will be correctly allocated to the response that produced it. In some of the latter modeling, m has been allowed to vary across time. The constant m, however, is a point estimate of a model that should describe how m changes with varying locations. Such a model was recently offered by the first 2 authors for the situation in which the distance apart of two response keys was varied. The present paper shows how an application of this model can describe the distribution of saccade latencies in data published by the last 2 authors.
