ABSTRACT
This chapter considers convergers and divergers and suggests that the convergence/divergence dimension is a measure of bias, not of level, of ability. The converger is the boy who is substantially better at the intelligence test than he is at the open-ended tests; the diverger is the reverse. J. W. Getzels and P. W. Jackson base their research on a distinction between two types of child: the ‘High IQ’ and the ‘High Creative’. Getzels and Jackson defined the difference between the ‘High IQ’ and the ‘High Creative’ in terms of scores on two contrasted types of mental test. Intelligence test questions may also be diagrammatical: logical relations expressed in terms of patterns. Open-ended tests, like intelligence tests, take different forms. Indeed, the variety is already rather bewildering. The convergence/divergence distinction is based on two open-ended tests. They are Uses of Objects; and Meanings of Words.
