Some Major Components in General Intelligence

Abstract

In most cognitive tests of conventional design the subject gains a mark for every problem correctly solved within a time limit. The score thus gained depends in part on the choice of problems attempted, in part on the rate at which the subject works, and in part on the extent to which he abandons problems which, given greater persistence, he might eventually solve correctly. Furthermore, the extent to which these different aspects of test and performance influence total score is quite unknown. Clearly, such a single score can be only an incomplete and probably quite inadequate summary of a very complicated problem solving performance.
