ABSTRACT
It has been suggested in the Introduction that the modern theory of intelligence constitutes a good example of a scientific paradigm. The conception of intelligence as general, innate cognitive ability is strongly supported by a great variety of researches. This chapter deals with two alternative models which attempt to change the picture of the structure of the intellect. It considers the authors Joy Paul Guilford, whose structure-of-intellect theory suggested the title, and Hans Eysenck, whose work falls into the same category, although quite different in intent and design from Guilford's. Guilford has called his theory the Structure-of-Intellect Theory, in order to demonstrate his departure from the Spearman-Thurstone tradition. His theory completely denies the existence of general intelligence, even as a higher order factor, and insists rather on the existence of a large number of independent abilities. Eysenck suggested a model-of-intellect which while it predicted some of the elements of Guilford's model differed strikingly from it in one respect at least.
