ABSTRACT
Studies of discrimination learning have repeatedly demonstrated that differential responding in the presence of various compound stimuli does not guarantee that all aspects of the stimuli actually exercise control over behavior. Instead, stimulus control is sometimes selective, and the contributions of the individual components of the compounds to ultimate stimulus control are interdependent. A primary goal of discrimination-learning theories has been to predict which, to what extent, and under what conditions the various elements of compound stimuli will gain behavioral control.
