Hans Eysenck believes these recent developments approximate a general paradigm which could form the
basis for future research. He explores the many special abilities verbal, numerical, visuo-spatial memory that contribute to our cognitive behavior. He examines pathbreaking work on "multiple" intelligence, and the notion of "social" or "practical" intelligence and considers whether these new ideas have any scientific meaning. Eysenck also includes a study of creativity and intuition as well as the production of works of art and science identifying special factors that interact with general intelligence to produce predictable effects in the actual world.
The work that Hans Eysenck has put together over the last fifty years in research into individual differences constitutes most of what anyone means by the structure and biological basis of personality and intelligence. A giant in the field of psychology, Eysenck almost single-handedly restructured and reordered his profession. Intelligence is Eysenck's final book and the third in a series of his works from Transaction.
