When a well‐learned circle versus ellipse discrimination was made impossibly difficult for the subjects (rhesus monkeys), the controlling stimulus‐response topographies were replaced by competing topographies. The identification of two training conditions sufficient to reinstate the original discrimination permitted the following inferences: the original controlling topography had merely decreased in probability of occurrence, whereas the “strength” of the stimulus‐response relation remained unchanged; discriminations along the apparently continuous circle‐ellipse dimension actually involved several distinct stimulus‐control topographies.
