ABSTRACT
The traditional psychological approach to achieve this goal has been to develop stimulus-response laws, including the hypothesization of a variety of logical constructs. The psychophysiologist’s approach has had shortcomings just as the classical behavioral approach, but for a different reason. Steps in developing a formal theory of covert processes require three hypothetical constructs and their interrelationships. Hypothetical constructs are defined by means of functional relationships between external stimuli (S) that anchor them on the antecedent side and overt responses (R) that anchor them on the consequent side. Perceptions, thoughts, ideas, images, hallucinations, dreams, or whatever are common-sense terms denoting cognitive events produced during internal information processing when various of these circuits are activated.
