1967 Research in Verbal Behavior and Some Neurophysiological Implications  
Professor Arthur Staats has, for a number of years, been conducting experimental and theoretical analyses in the task of developing what he calls an integrated-functional learning theory of human behavior  ...  In addition to providing a conception of human behavior, one of the aspects of the theory is that its principles and methods should contribute to the solution of problems of human behavior.  ...  When this has occurred the new stimulus will come to elicit the conditioned part of the sensory response, which we commonly call an image.  ...
