Universal semantic differential shell game

Examines T. Reed's (see PA, Vol. 49:Issue 5) study and presents conceptual and methodological criticism of those semantic differential studies that purport to establish a unique structure for some specified class of concepts. Specifically, the logical conditions for strategic sampling of the meaning domains that accrue to the semantic differential are discussed in an attempt to ascertain the boundary conditions of that generative theory from which predictions of an evaluation, potency, activity structure can or cannot be derived.
