COMPLEX STIMULUS-CONTROL AND EQUIVALENCE

A matching-to-sample procedure that engenders observation of two eleme nts of a complex sample stimulus may establish equivalence relations a mong those elements. Studies that focus on complex stimulus control wi ll help determine the necessary and sufficient conditions for equivale nce class formation. Further studies in this area will benefit by blen ding the methods and concepts of stimulus equivalence research with th ose used in studies of conceptually related learning processes. The en terprise may also profit by reconsidering the role of compound stimulu s control in the formation of equivalence.
