CONTRIBUTIONS TO INTELLIGENCE TESTING AND THE THEORY OF INTELLIGENCE
Summary.— In offering what purport to be definitions of intelligence, psychologists do not always seem to have worked out what sense of the word ‘definition’ they have in mind. Six possible senses of the word ‘definition’ are here distinguished. Each sense is then discussed with special reference to the problem of defining intelligence. In the light of the distinctions made, the definitions of intelligence offered by Wechsler and Burt are critically examined from the point of view of methodology.
